PROCESS FOR PRODUCING DIMETHYL (2,2,2-TRICHLORO-1-HYDROXYETHYL)-PHOSPHONATE AND GRANULAR FORMULATIONS THEREOF |
摘要 |
The present invention relates to an integrated process for synthesizing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate and a process for impregnating the dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate on to inert carrier granules. The process involves adding dimethyl phosphite to a reaction mixture containing chloral under anhydrous, inert conditions. The molar ratio of chloral to dimethyl phosphite used in the reaction mixture is from about 1.0:1.0 to about 1.1:1.0. The impregnation process involves transferring molten dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate into a process vessel and discharging weighed aliquots into a formulation vessel to form a granular product containing dimethyl (2,2,2-trichloro-1-hydroxyethyl)-phosphonate. |
