Abstract:
1. A process for preparing soluble granules comprising, a) premixing 75 to 98 wt. % a phosphoroamidothioate compound of the following formula: wherein R and R 1 individually are an alkyl, alkenyl or alkynyl group containing up to 6 carbon atoms, R 2 is hydrogen, an alkyl group containing 1 to 18 carbon atoms, a cycloalkyl group containing 3 to 8 carbon atoms, an alkenyl group containing 2 to 18 carbon atoms or an alkynyl group containing 3 to 18 carbon atoms, R 3 is hydrogen or an alkyl group containing 1 to 6 carbon atoms, and Y is oxygen or sulfur; 0.1–3.0 wt. % a wetting agent and a filler to make 100 wt. %, to form a substantially dry premix; b) grinding said substantially dry premix to produce a ground product having a predetermined particle size; c) post-mixing said ground product to produce a mixture; d) granulating said mixture using an agitative ball process to produce granules; e) conditioning said granules to produce conditioned granules; and f) sieving said conditioned granules to separate fines which are less than a predetermined granular size.
