Scope
Main technical content: This document specifies the requirements for ammonium sulfate produced as a by-product of D-methylsulfonyl benzyl serine ethyl ester (D-ethyl ester), testing methods, inspection rules, marking and accompanying documents, packaging, transportation, and storage, etc. This document applies to the aqueous solution of ammonium sulfate produced in the esterification process of D-methylsulfonyl benzyl serine ethyl ester. After extraction, decolorization, and centrifugal concentration, the ammonium sulfate produced as a by-product of D-hydroxyl benzyl glycine methyl ester is mainly used in municipal greening, rare earth mining, and leather degreasing agents, etc.
