Abstract

The invention discloses a method for compounding high-purity sulfuric acid esters, wherein alcohol and thionyl chloride react to generate a midbody A, the midbody A is reacted in oxidizing agents to generates sulfuric acid esters. The method for compounding the high-purity sulfuric acid esters has the beneficial effects that the method for compounding the high-purity sulfuric acid esters use the alcohol, the thionyl chloride and the oxidizing agents as raw materials, wherein the alcohol, the thionyl chloride and the oxidizing agents are easy to obtain, and are low in cost. The method for compounding the high-purity sulfuric acid esters is high in selectivity, does not have side effect, is high in yield and strong in universality, and is suitable for all complex high grade sulfuric acid esters. The method for compounding the high-purity sulfuric acid esters is simple in production operation, is low in demands on process equipment, does not have corrosivity, does not need strict production conditions such as high pressure high temperature or high pressure low temperature and the like, is easy for industrial scale production and small in pollution to environment, and accords with environmental protection requirements of green production.

Description

technical field

[0001] The invention belongs to the field of organic chemistry, in particular to a method for synthesizing high-purity sulfuric acid diester. Background technique

[0002] Sulfuric acid esters such as structural formula (I) are organic ester derivatives of sulfuric acid, the general formula R-O-SO 2 -O-R',

[0003]

[0004] When R is an organic group and R' is a proton or no group (i.e., a sulfate at one end), the general formula represents a sulfuric acid monoester, such as the detergent sodium lauryl sulfate derived from lauryl alcohol and chlorosulfonic acid , and ethoxylated fatty alcohols such as sodium lauryl polyoxyethylene ether sulfate used in daily necessities. When R and R' are both organic groups, the general formula represents a sulfuric acid diester, usually a symmetrical sulfuric acid diester (that is, R=R'), and diethyl sulfate and dimethyl sulfate are common.

[0005] Sulfate ester is an important class of organic chemical raw materials...
