STABLE EMULSION OF ORGANIC PHOSPHORIC ACID ESTER AGRICULTURAL CHEMICAL

摘要

PURPOSE:To obtain a stable emulsion containing an organophosphorus agent effective in preventing the formation of precipitate during storage, by using a propylene glycol derivative as a stabilizer and adding the stabilizer to an organic phosphoric acid ester agricultural chemical. CONSTITUTION:The objective stable emulsion of organic phosphoric acid ester agricultural chemical contains at least one kind of propylene glycol derivative of formula (R1 and R2 are H or 1-6C alkyl; n is 1 or 2) (e.g. propylene glycol monomethyl ether). The amount of the propylene glycol derivative is 1-10wt.% based on the emulsion and is >=0.6wt.%, preferably >=2wt.% based on the organophosphorus agent.
