New discoveries in chemical research and development in 2021.In classical electrochemical theory, both the electron transfer rate and the adsorption of reactants at the electrode control the electrochemical reaction. In an article, author is Ouyang, Ruiling, once mentioned the application of 636-41-9, Name is 2-Methyl-1H-pyrrole, molecular formula is C5H7N, molecular weight is 81.12, MDL number is MFCD02822910, category is pyrrolines. Now introduce a scientific discovery about this category, Application In Synthesis of 2-Methyl-1H-pyrrole.
Solubility Measurement and Data Correlation of Thiabendazole in 12 Pure Organic Solvents from 283.15 to 323.15 K
The solubility of thiabendazole (TBZ) in 12 organic solvents (methanol, ethanol, n-propanol, isopropanol, n-butanol, isobutanol, acetone, butanone, methyl acetate, ethyl acetate, n-butyl acetate, and acetonitrile) was determined by the gravimetric method from 283.15 to 323.15 K. The solubility in all selected solvents increases with increasing temperature and in acetonitrile changes much greater than that in other solvents as temperature increases. The solubility of TBZ is higher in alcohol and ketone solvents than those in esters and nitriles. Besides, the solubility is mainly related to the solvent polarity and cohesive energy density in nonalcohols and influenced by the complicated combination of many factors in alcohols. Further, the Apelblat model, lambda h model, and NRTL model were used to correlate the solubility of TBZ. The relative deviation is less than 2.23% with the modified Apelblat equation, which shows better fitting performance compared with other two models.
