摘要

A process for the preparation of new water-soluble, physically stable, insecticidal and nematicidal concentrates comprising (a) s-methyl {(methylcarbamoyl) oxy} thioacetimidate and (b) n ", n" -dimethyl-n - methyl {(methylcarbamoyl) oxy} -1-thiooxamyimidate in a solvent, the latter being selected from solvent systems consisting of methanol/water containing from 0 to 70% by weight of water; acetone/water containing about 0 to 70% by weight of water and cyclohexanone/cyclohexanol/methanol/water containing about 20 to 92% by weight of cyclohexanone and cyclohexanol, with the proviso that at least about 35% of this component is cyclohexanone, about 3 to 25% by weight of methanol and at least about 5% by weight of water, the ratio of (a) to (b) being from 2: 1 to 1: 2.5 approximately, keeping said composition at a ph of about 2.8 to 3.2, and, optionally, a coloring agent, whose method consists of introducing the solvent system and the acid required to bring the ph to the designated value, in a container equipped with a device mixer and optionally, devices for covering the container with nitrogen or with another inert gas, to properly combine both products.
