Sulfuric ester - sulfuric ester

Japanese: 硫酸エステル - りゅうさんエステル(英語表記)sulfuric ester
Sulfuric ester - sulfuric ester
A general term for compounds in which one or two hydrogen atoms of the dibasic acid sulfuric acid (HO) 2 SO 2 are replaced by a hydrocarbon group R. There are two types: acidic esters (monoesters) RO-SO 2 -OH and neutral esters (diesters) RO-SO 2 -OR. Acidic esters are produced by reacting alcohol with concentrated sulfuric acid or fuming sulfuric acid. They can also be obtained by adding sulfuric acid to alkenes. Acidic esters are viscous liquids and cannot be distilled. They dissolve in water and are hydrolyzed to alcohol when heated.
