Abstract

A process of generating a glycerol ether is provided. The process includes reacting isobutylene with an alcohol to obtain a tertiary alkyl ether through an etherification reaction and generating a glycerol ether from the tertiary alkyl ether and glycerol through a transetherification reaction, A system for generating a glycerol ether is also provided.

Description

technical field [0001] The subject matter of the present disclosure relates to methods and systems for producing glyceryl ethers. Background technique [0002] Glycerol, also known as glycerin, is a colorless, odorless, viscous liquid. Glycerin has various uses including, for example, as an antifreeze agent and as an excipient in certain pharmaceutical formulations. Glycerol occurs in nature and can also be prepared synthetically by various routes. One source of glycerol is the commercial production of biodiesel. Glycerol can be a waste product in the production of biodiesel. [0003] Biodiesel is a fuel or a component of fuel that can be used for various purposes, including powering diesel engines. Biodiesel is gaining attention as a renewable fuel and can complement and / or replace various fossil fuels. Biodiesel is generally a mixture of compounds including alkyl esters of natural fatty acids, and can be produced by transesterification of triglycerides with simple alc...
