Usage

General Description

Dipropyl sebacate, also known as DPS, is a chemical compound commonly used as a plasticizer in the production of various synthetic materials and products. It is a clear, colorless liquid that is insoluble in water but can dissolve in organic solvents. DPS is known for its ability to improve the flexibility and durability of polymers, making it suitable for use in the manufacturing of adhesives, coatings, and other industrial materials. Its low volatility and high thermal stability also make it a popular choice for applications in the automotive and aerospace industries. Additionally, dipropyl sebacate is considered to be relatively safe and is approved for use in food packaging and medical devices, further expanding its range of applications.

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.
