Title: Production of high-purity monoglyceride sulfate
Inventor: YAMASHITA KAZUHIKO
IPC: C07C309/17
Filed: 1982-11-15
Abstract: PURPOSE:A specific aliphatic alcohol is used to remove the remaining reagents, when a fatty acid monoglyceride is sulfated with a specific amount of fuming sulfuric acid, to produce the titled compound used as a surfactant under mild conditions, preventing hydrolysis, in high purity. CONSTITUTION:In the sulfation of a fatty acid monoglyceride with 5-20% fuming sulfuric acid, an aliphatic alcohol of CnH2n+1OH (n is 4 and/or 5) such as n-butyl alcohol or isobutyl alcohol is used to remove the remaining reagent, thus giving fatty acid monoglyceride sulfate. The process enables the formation of sulfate ester with a considerably small amount of sulfating reagent and reduces the dilution heat of the reaction mixture remarkably, thereby the decomposition of the product can be extremely reduced even in its mass production. Further, when the reaction mixture is poured in water or a mixture thereof with butanol, the objective product goes into the alcohol layer to prevent the ester from being hydrolyzed to facilitate the separation from the sulfuric acid layer.
