Method of preparation and use of solid, phytoactive compositions.

摘要

A method for the preparation of a solid, phytoactive composition comprising: (a) reacting an acid form of a phytoactive N-phosphonomethyl-N-carboxylmethyl compound with a liquid amine to form the amine salt of said N-phosphonomethyl-N-carboxylmethyl compound; (b) admixing said amine salt of said N-phosphonomethyl-N-carboxylmethyl compound with a molten surfactant, the surfactant being solid at ambient temperatures; and (c) cooling said mixture to a temperature below the melting point of the surfactant to form a composition comprising said surfactant and said amine salt of N-phosphonomethyl-N-carboxylmethyl compound interdispersed in the matrix thereof and which is solid at ambient temperatures.
