A kind of low carbon olefin hydration process

Abstract

A low carbon olefin hydration technology comprises the following steps: injecting water to a raw material tank full of liquid low carbon olefin, conveying the liquid low carbon olefin to water and a reactor under the extrusion of water, and carrying out a hydration reaction under the action of a catalyst under a liquid-volume hourly space velocity of the liquid low carbon olefin of 0.5-2.5h<-1> under a water / olefin mole ratio of 0.8-2.5 at a temperature of 135-170DEG C under a pressure of 5.0-10.0MPa. The technology is simple to operate, and can obviously improve the long period running stability of a method for preparing low carbon alcohol through hydration of the low carbon olefin.

Description

technical field [0001] The invention relates to a low-carbon olefin hydration process, in particular to a low-carbon olefin hydration process for producing low-carbon alcohol capable of long-term and high-stability operation. technical background [0002] The hydration reaction of light olefins is an important catalytic process. In the hydration reaction, the most representative and practical value is the preparation of alcohols through the hydration reaction of low-carbon olefins, such as ethanol, isopropanol, sec-butanol and other low-carbon alcohols. As important organic chemical raw materials and solvents, low-carbon alcohols have a very wide range of uses. Ethanol can be used to make dyes, paints, drugs, synthetic rubber, and detergents. Isopropanol can be used in the synthesis of glycerin and acetone, and can also be used in the synthesis of fine products such as pesticides and spices. Second-butanol is widely used in the synthesis of methyl ethyl ketone, or as a ra...
