N-Cyanoimido-S,S-dimethl-dithiocarbonate - Preparation Method
Open Data Verified Data
calcium dithioate was obtained by the reaction of lime nitrogen with carbon disulfide. After the waste residue was separated by centrifugation, dimethyl dicalcium dithioate was reacted with dimethyl sulfate by methyl esterification to obtain dimethyl cyanoimine dithiocarbonate. After separation and removal of calcium sulfate and low boiling material, to obtain the finished product.
