Abstract

Belonging to the chemical field of plasma synthesis, the invention relates to a method for direct preparation of polyols and higher alcohols from ethanol. The method is characterized by: choosing dielectric barrier discharge, corona discharge, pulsed corona discharge, glow discharge, radio frequency discharge, gliding arc discharge or microwave plasma and other discharge methods to perform selective activation to ethanol molecules, then setting the residence time of a reaction mixture in a reaction zone, the discharge reaction temperature, the discharge reaction pressure, and the mole ratio between a carrier gas and ethanol, conversing the selectively activated ethanol into target products. The method of the invention adopts ethanol as the raw material for preparing polyols and higher alcohols, while ethanol has various sources and renewability. The method provided in the invention belongs to a one-step synthesis technology, and has the advantages of no need for catalyst, no environmental pollution, as well as high selectivity.

Description

technical field

[0001] The invention belongs to the field of plasma synthesis chemistry and relates to a new method for directly preparing high-carbon alcohols and polyhydric alcohols from ethanol. Background technique

[0002] Ethanol is an important basic organic chemical raw material with a wide range of uses. Most notably, it is used in the synthesis of low-carbon olefins such as ethylene, propylene, and butene; in addition, it can also be used to produce hydrogen, gasoline, aromatics, acetaldehyde, acetic acid, propionic acid, dibutyl ether, ethyl acetate, dimethyl Ether, vinyl acetate, etc. Since ethanol can be obtained by converting biomass, it has attracted more and more attention as a new type of renewable clean energy.
