Mechanism and kinetic model for glycerolysis of shellac

IOP Conference Series: Materials Science and Engineering, 2020
Abstract Shellac is a resin which is secreted from Kerria lacca, that can be utilized for coating and polyester. This material is brittle and stiff, hence modification of shellac is needed. One alternative to change its properties is by modification with glycerol.

Sustainable Recovery of Plant Lipase From Pequi Peel (caryocar brasiliense camb.) in Aqueous Two‐Phase Systems: An Optimization Approach

ChemistrySelect, Volume 10, Issue 46, December 8, 2025.
ABSTRACT While plant residues represent promising low‐cost enzyme sources, their efficient recovery remains a challenge for industrial biocatalysis. This study aimed to optimize thepurification of lipases extracted from pequi peel (Caryocar brasiliense Camb.) using aqueous two‐phase systems (ATPS) composed of polyethylene glycol (PEG) 1500 g/mol and ...

Optimized bifunctional CuNiMgAl catalysts for efficient synthesis of the renewable bioproduct glycerol carbonate

Biofuels, Bioproducts and Biorefining, Volume 19, Issue 5, Page 1271-1288, September/October 2025.
Abstract This paper presents a novel technology for converting glycerol, a byproduct of the biodiesel industry, into glycerol carbonate, a high‐value bioproduct. The effect of calcination temperature on the synthesis of quaternary Cu‐Ni‐Mg‐Al catalysts (MMO‐Cu15Ni15‐Tz) and their application in the transesterification reaction was investigated ...
