Valorisation of glycerol by new mechanochemical processes [PDF]

open access: yes, 2019
The search for new applications of glycerol, as a chemical platform from which a broad spectrum of new valuable derivatives can be obtained, is ongoing. In the present communication, a new mechano-chemical reactor is used for the valorisation of glycerol,

Transesterification Reactions Catalyzed by Papain

open access: yesJournal of Biological Chemistry, 1966
Abstract The hydrolysis of a series of esters of benzoyl-L-arginine and glycylglycine by papain has been examined in mixtures of water with various alcohols in the pH range of 5 to 6. The presence of straight chain alcohols resulted in an apparent inhibition of acid release.

Experimental and Modeling Studies of the Reaction Kinetics of Alkaline-Catalyzed used Frying Oil Glycerolysis using Isopropyl Alcohol as a Reaction Solvent [PDF]

open access: yes, 2012
An alkaline catalyzed glycerolysis of used frying oil using sodium hydroxide and isopropyl alcohol as solvent was investigated. A reaction kinetic model considering glycerol-triglyceride solubility and a second order kinetic mechanism was also developed.

Ionic liquids as transesterification catalysts: applications for the synthesis of linear and cyclic organic carbonates

open access: yesBeilstein Journal of Organic Chemistry, 2016
The use of ionic liquids (ILs) as organocatalysts is reviewed for transesterification reactions, specifically for the conversion of nontoxic compounds such as dialkyl carbonates to both linear mono-transesterification products or alkylene carbonates.

Transesterification Reactions Catalyzed by Subtilisins

open access: yesJournal of Biological Chemistry, 1966
Abstract The hydrolysis of l-tyrosine ethyl ester by Carlsberg subtilisin, subtilisin BPN', and Novo bacterial proteinase has been examined in mixtures of water with various alcohols. The presence of straight chain alcohols resulted in an apparent inhibition of acid release.

Lipid content and biomass analysis in autotrophic and heterotrophic algal species [PDF]

open access: yes, 2016
Biofuels are a form of renewable energy derived from living matter, typically plants. The push for biofuels began in order to decrease the amount of carbon dioxide (CO2) released into the atmosphere, as biofuels are essentially carbon neutral.
