Biomass-derived dibasic acids to diesters with inorganic ligand-supported catalyst: synthesis, optimization, characterization

Several attempts have been made to obtain aliphatic dicarboxylic diesters from esterification reaction to develop the biomass-derived platform molecules and green manufacturing processes. In this paper, Na3(H2O)6[AlMo6O18(OH)6], an Anderson-type polyoxometalate, firstly, was reported as a catalyst for diester synthesis from dicarboxylic acid to diester which showed an well productivity and selectivity characterized by 1H and 13C. Response surface methodology (RSM) integrated with the desirability function approach was used to determine the best operative conditions, and the optimal reaction parameters for maximum dipropyl succinate yield (77 ± 2.5%) were identified as 1.19?mol.% catalyst loading, 4.9:1 propanol/succinic acid ratio, 113?°C, and 9.6?h. Three batches of tests were carried for catalyst recycling with 78–75% yield even after 6 cycles of esterification. In addition, the substrate carbon chain was increased for investigation of substrate scope achieving satisfactory results and all products were characterized by 1H and 13C nuclear magnetic resonance spectroscopy.

A kind of preparation method of succinic acid diester

Disclosed is a method for preparing succinic acid diester, in which levulinic acid or levulinate esters are used as raw materials, molecular oxygen is used as oxygen source, and succinic acid diester is produced by catalytic selective oxidation and esterification reaction. The levulinic acid or levulinate esters used as raw materials in the method can be obtained from biomass such as cellulose, starch, agricultural and forestry residues or the like. The method is a new route for preparing succinic acid diester that does not rely on fossil resourse. As the reaction condition in the process is moderate and has a high succinic acid diester selectivity, it has important application prospect.

Vapor pressures and enthalpies of vaporization of a series of the symmetric linear n -alkyl esters of dicarboxylic acids

Vapor pressures and the molar enthalpies of vaporization of the linear aliphatic alkyl esters of dicarboxylic acids R-CO2-(CH 2)n-CO2-R with n = (0 to 4) with R = C 2H5, n-C3H7, and n-C 4H9 have been determined using the transpiration method. A linear correlation of enthalpies of vaporization (at T = 298.15 K) of the esters with the number n and with Kovat's indices has been found, proving the internal consistency of measured data.
