A catalyst-free and recycle-reinforcing elastomer vitrimer with exchangeable links

Vitrimers, as intriguing polymers, possess exchangeable links in the crosslinking networks, endowing them with the abilities of recycling and reprocessing. However, most of vitrimers are generally fabricated via complex synthesis and polymerization processes. Toxic and unstable exogenous catalysts are inevitably applied to activate the exchange reaction to rearrange the crosslinking networks. These drawbacks limit the widespread applications of vitrimers. Moreover, most reported vitrimers could only partially maintain or severely deteriorate their mechanical properties after recycling. Herein, to solve the above-mentioned problems, for the first time, a catalyst-free and recycle-reinforcing elastomer vitrimer is revealed. By the reactive blending of commercially available epoxidized natural rubber and carboxylated nitrile rubber, the elastomer vitrimer associated with exchangeable beta-hydroxyl ester bonds was obtained. Strikingly, the vitrimer exhibits an exceptional recycle-reinforcing property. This work provides a feasible method to fabricate elastomer vitrimers, which promotes the recycling of crosslinking commercial available elastomers.

Solubility measurement, model evaluation and Hansen solubility parameter of piperonylonitrile in four binary solvents

The present research work proposed the mole fraction solubility and mixing thermodynamic properties of piperonylonitrile in different binary solvent mixtures such as ethanol + (acetone, 1,4-dioxane, DMF and methyl acetate) at T = 278.15 K to 323.15 K and p = 0.1 MPa. The results indicated that as the temperature and mass fraction of positive solvents increased, the measured solubility of piperonylonitrile increased in all mixtures considered. Analysis using Hansen solubility parameter revealed that the affinity between piperonylonitrile and all mixed solvents was related to multiple factors. The experimental solubility of piperonylonitrile in four binary solvent mixtures was regressed by employing four thermodynamic models such as UNIQUAC, Margules, Wilson and NRTL model. It was found that the Wilson model was accurate enough to correlate the experimental solubility. Moreover, the mixing thermodynamic properties of piperonylonitrile in different mixed solvents were also estimated and discussed according to the Wilson model and experimental data. The results of the negative Delta(mix)G values and positive Delta S-mix values demonstrated the entropy-driven and spontaneous mixing process of piperonylonitrile in all binary solvent mixtures.

Application of analytical pyrolysis to gain insights into proteins of condensed corn distillers solubles from selective milling technology

Present study evaluates the analytical pyrolysis to unravel the pyrolysate compounds (PyCs), protein & glycosylation indicators in a protein fraction (PF) from condensed corn distillers solubles (CCDS) of novel selective milling technology. Besides, quadratic and linear corre-lations using protein content (%) by Dumas method, toluene signature PyC, and elemental nitrogen (%) were developed. Pyrolysis was performed at temperature of 400 degrees C, where most of the PyCs released from proteins in a lignin-free PF instead of other constituents. The p cresol and methyl 9,12-octadecadienoate were found with the highest area% of 3.2 and 19.3 in PF and CCDS, respectively. Protein derived PyCs such as nitrogen heterocyclics, amines & amides and nitriles were examined 63.93%, 61.90% and 70% greater in PF than CCDS. Moreover, the indicators of protein were toluene, p-cresol, phenol, phenylacetonitrile, 4vinylphenol, whereas that of glycosylated protein were methyl mercaptan, furan derivatives, and hexahydro-3-(phenylmethyl) pyrrolo [1, 2 a] pyrazine-1,4-dione. The absence of diketopiperazines provided evidence of crosslinking and aggregation of protein. The values of the protein content obtained from the quadratic model and Dumas method were found to be statistically non-significant (p < 0.05) imply the model validity. The results would aid in bioconversion of CCDS to future value-added products. (C) 2020 Institution of Chemical Engineers. Published by Elsevier B.V. All rights reserved.

Liquid crystal dimers and the twist-bend nematic phase: On the role of spacers and terminal alkyl chains

The synthesis and characterisation of four series of liquid crystal dimers based on benzylideneaniline mesogenic units, and in which the lengths of terminal alkyloxy chains are varied are reported. The series differ in terms of their flexible spacers, namely, heptamethylene, nonamethylene, hexyloxy, and oxypentyloxy chains. The heptamethylene- and nonamethylene-linked dimers both show conventional nematic, N, and twist-bend nematic, N-TB, phases with short terminal chains, and smectic behaviour emerges on increasing terminal chain length. This is attributed to increased molecular inhomogeneity driving microphase separation. The dimers containing the shorter heptamethylene spacer show a smectic A phase whereas those with the longer nonamethylene spacer exhibit an anticlinic smectic C phase. Smectic behaviour is not observed for the dimers containing either a hexyloxy spacer which exhibit nematic and twist-bend nematic phases, or with an oxypentyloxy spacer which show only a conventional nematic phase. A general observation is that T-NTBN and T-NI alternate in the same sense in a homologous series on varying the length of the terminal alkyl chains suggesting that the spatial uniformity of the molecular curvature is an important factor in stabilising the N-TB phase. The transitional properties of the four corresponding dimers possessing nitrile terminal substituents are also described. These show enantiotropic nematic phases, and in addition, for those containing either polymethylene or hexyloxy spacers, a twist-bend nematic phase is observed. Differences in the thermal behaviour of the dimers may be attributed largely to changes in molecular shape arising from the nature of the link between the spacer and mesogenic units.

Studies on the oxidation of 2,2,4-trisubstituted 3-pyrrolines

As part of our studies directed towards a total synthesis of lactacystin, we have developed a reliable and environmentally acceptable method to oxidise 2,2,4-trisubstituted 3-pyrrolines to the corresponding 3-pyrrolin-2-ones. Several protocols were examined and the two-step (i) TPAP/NMO; (ii) sodium hypochlorite allylic oxidation was found to be the most satisfactory. Catalytic oxidation of the 3-pyrroline afforded the corresponding cyclic imine in high yield, and subsequent oxidation with NaOCl afforded the N-chloro-3-pyrrolin-2-one. The N-chloro-substituent was removed by a simple acid treatment. (C) 2002 Published by Elsevier Science Ltd.

Detection of CH3C3N in Titan’s Atmosphere

Titan harbors a dense, organic-rich atmosphere primarily composed of N-2 and CH4, with lesser amounts of hydrocarbons and nitrogen-bearing species. As a result of high-sensitivity observations by the Atacama Large Millimeter/submillimeter Array (ALMA) in Band 6 (similar to 230-272 GHz), we obtained the first spectroscopic detection of CH3C3N (methylcyanoacetylene or cyanopropyne) in Titan’s atmosphere through the observation of seven transitions in the J = 64 -> 63 and J = 62 -> 61 rotational bands. The presence of CH3C3N on Titan was suggested by the Cassini Ion and Neutral Mass Spectrometer detection of its protonated form: C4H3NH+, but the atmospheric abundance of the associated (deprotonated) neutral product is not well constrained due to the lack of appropriate laboratory reaction data. Here, we derive the column density of CH3C3N to be (3.8-5.7).x.10(12) cm(-2) based on radiative transfer models sensitive to altitudes above 400 km Titan’s middle atmosphere. When compared with laboratory and photochemical model results, the detection of methylcyanoacetylene provides important constraints for the determination of the associated production pathways (such as those involving CN, CCN, and hydrocarbons), and reaction rate coefficients. These results also further demonstrate the importance of ALMA and (sub)millimeter spectroscopy for future investigations of Titan’s organic inventory and atmospheric chemistry, as CH3C3N marks the heaviest polar molecule detected spectroscopically in Titan’s atmosphere to date.

Influence of ultraviolet aging on the structure, mechanical and gas permeability properties of hydrogenated nitrile butadiene rubber

The effect of ultraviolet (UV) radiation on the structure and performance of hydrogenated nitrile butadiene rubber (HNBR) was studied in this paper. The HNBR was exposed to UV radiation for various durations (0, 7, 14, 21 and 28 days). The Fourier transform infrared spectroscopy (FTIR) results demonstrated that the surface molecular structures were oxidized to generate oxygenated species under UV radiation. The oxidative degree enhanced with the increase of aging time, resulting in thicker and denser cracks on the surface. The plausible aging mechanism of HNBR was suggested. The free volume of HNBR before and after UV aging was characterized by positron annihilation lifetime spectroscopy (PALS) and their cross-linking density, compression set, mechanical and gas permeability properties were also analyzed. In the first 14 days of UV irradiation, the dominant chain-scission reaction led to a decrease in cross-linking density of HNBR, resulting in the enhancement of free volume and thereby the increase of gas permeability. When the aging time was longer than 14 days, cross-linking reaction played a leading role and the free volume decreased, thus causing the reduction of gas permeability. As the aging time increased, the glass transition temperature (T-g), tensile strength and storage modulus of HNBR initially reduced and then increased, which was in agreement with the changing trend of cross-linking density.
