The kinetics of the homogeneous acylation of microcrystalline cellulose, MCC, with carboxylic acid anhydrides with different acyl chain-length (Nc; ethanoic to hexanoic) in LiCl/N,N-dimethylacetamide have been studied by ...

The N-acylation reaction of a series of lactams of biological interest, derived from 2-benzoxazolinones and 1,4-benzoxazin-3-one, with acetic anhydride has been studied. The reaction yields show the same tendency as that ...

The present work covers an important gap in the field of analytic standards synthesis of the plants minor component, the acyl steryl glucosides (ASG). A simple and powerful procedure that allows the synthesis of different ...

Gas phase acylation of guaiacol on acid solids was studied using catalysts with different acid site density, nature and strength. The main products formed were acetovanillone, 2-acetoxyanisole and catechol using acetic ...

The gas-phase synthesis of aromatic ketones via acylation of phenol with acetic acid was studied on SiO2–Al2O3, Al-MCM-41, zeolites HY and ZSM5, and tungstophosphoric acid (HPA) supported on MCM-41 and carbon. At contact ...

The deactivation mechanism of the gas-phase synthesis of o-hydroxyacetophenone (o-HAP) via acylation of phenol with acetic acid was studied on Al-MCM-41 and zeolites HY, HBeta and HZSM-5. The o-HAP yield remained constant ...

In this work, the ethanolysis of triglycerides catalyzed by immobilized lipase was studied, focusing on the secondary reaction of acyl migration. The catalytic tests were performed in a solvent-free reaction medium using ...
