| titleOfInvention | Process for the production of dithiocarbamates from polyols, in particular glycerol type polyols |
| abstract | The present invention relates to a process for producing glycerol dithiocarbamate or bisdithiocarbamate (GDTC). In this method, (1) a glyceryl-type polyol associated with a carbonate selected from diethyl carbonate, dimethyl carbonate, and ethylene or propylene carbonate in the presence of a basic catalyst; or (2) a five-membered ring in a solvent medium In the presence of carbon disulfide, a primary or secondary amine is added to a reaction medium containing a cyclic carbonate of GDTC, and then the formed GDTC is removed. More specifically, a glycerol-type polyol was formed by contacting with diethyl carbonate in the presence of a catalyst and then adding to the reaction medium a primary or secondary amine in the presence of carbon disulfide. Remove GDTC. The present invention makes it possible to synthesize glyceryl dithiocarbamate in one step directly from glycerol as a starting material and a solvent. This method uses glycerol, diethyl carbonate, carbon disulfide (CS 2 ), and primary or secondary amines to obtain glyceryl dithiocarbamate; the glycerol / NaOH phase significantly reduces the yield Can be reused 6 times; ethyl acetate can also be reused after each extraction. |
