Kinetic Study of Glycerol Monolaurate (GML) Production from Glycerol with Lauric Acid Using a Dealuminated Zeolite Y Catalyst (original) (raw)

IOP conference series, 2021

Abstract

This study aims is to study the ability of zeolite Y to produced higher yield of glycerol monolaurate. This study focused on dealumination zeolite synthesis Y applied on glycerol monolaurate synthesis and kinetic study of glycerol monolaurate synthesis. The stages of this research consisted of zeolite Y catalyst dealumination, synthesis of glycerol monolaurate and acid-base analysis of catalyst. The esterification process was carried out with 1: 7.5 mole ratio of reactant (glycerol/lauric acid) at 1300C and a stirring speed of 300 rpm. Data obtained from the experimental results show that the longer the time used, the greater the ability of the zeolite Y to synthesize the glycerol monolaurate. The esterification process was carried out by using 2nd order rate equation with R2 about 0,9051 with ratio of the first reactant CA0≠CB0. The determination of k value was expressed by equation l n M − X A M ( 1 − X A ) = ( C B O − C A O ) k t . Constant reaction rate value of glycerol monolaurate is 0,006805 L/mol.min.
