Abstract

Glycerol carbonate has gained attention as a value-added product from reacting glycerol and dimethyl carbonate. This work studies the dispersion in nonreacting conditions of the two compounds under...

Highlights

  • Over the past decade there have been a large number of studies on the chemical valorization of the surplus of glycerol (Gly) generated by the biodiesel industry owing to the steep decrease of its retail prices.[1]

  • A thorough study of the dispersion of glycerol in dimethyl carbonate was conducted in a stirred vessel fitted with a Rushton turbine

  • The droplet size distribution (DSD) when the viscosity of the dispersed phase was high were bimodal, which indicates that better coalescence takes place compared to moderate viscosities of the dispersed phase, whose distributions were unimodal

Summary

Introduction

Over the past decade there have been a large number of studies on the chemical valorization of the surplus of glycerol (Gly) generated by the biodiesel industry owing to the steep decrease of its retail prices.[1] These studies include several processes conducted by microorganisms, enzymes, or catalytic processes, which have been thoroughly covered in the literature.[2−4]. Over the past decade there have been a large number of studies to obtain glycerol carbonate (GC) as a value-added chemical from the valorization of glycerol (Gly).[8,9] Its properties make it a valuable product in many applications as a green solvent for reactions and separation processes or in batteries, in the formulations of cosmetics and foods, or as a building block for polymers and surfactants.[8] GC production can be performed by transcarbonation with organic carbonates such as dimethyl,[10,11] diethyl,[12] ethylene,[10,13] propylene, and butylene carbonates.[14]
