摘要： A process for preparation of thiocyclam base and salt. A method of manufacturing N,N-dimethyl-1,2,3-trithian-5-ylainine hydrochloride is described including the steps of: providing a mixture of thiosulfuric acid S, S′[2-(dimethylamino) trimethylene] ester monosodium salt and sodium hydroxide; adding an aqueous saline solution to the mixture of thiosulfuric acid S, S′-[2-(dimethylamino) trimethylene] ester monosodium salt and sodium hydroxide; separating the phases of the mixture; collecting the solids from the mixture using filtration; washing the solids with organic solvent; and drying the solids, where the dried solids are methyl-1,2,3-trithian-5-ylamine hydrochloride, and where the yield of the N,N-dimethyl-1,2,3-trithian-5-ylamine hydrochloride is increased by incorporation of a body charge of diatomaceous earth into the saline addition step, forming a mixture of the diatomaceous C earth with the composition of this step, and filtering the charged mixture through a diatomaceous earth media prior to the separation step.

摘要： Encapsulation of cyclohexanediones process and product. A composition particularly adapted for herbicidal use is described, including biopolymer micro-capsules containing one or more cyclohexanediones encapsulated therein, resulting in enhanced chemical stability and dispersibility of the encapsulated cyclohexanediones for such use. A complex coacervation method of forming such microcapsules is also described.

摘要： Preparation of O,O-dimethyl phosphoramidothioate and O,O-dimethyl phosphoroamidothioate. A process of making O,O-dimethyl phosphoroamidothioate is described including reacting sulfur with PCl3 to form PSCl3, reacting the PSCl3 formed with methanol to form O-methyl phosphorodichloridothioate, and reacting the O-methyl phosphorodichloridothioate formed with methyl lye to form O,O-dimethyl phosphorochloridothioate in solution in CH2Cl2, and reacting the O,O-dimethyl phosphorochloridothioate formed with sodium hydroxide and ammonium hydroxide to form O,O-dimethyl phosphoroamidothioate in solution in CH2Cl2. Reacting the O,O-dimethyl phosphoroamidothioate formed with catalytic dimethyl sulfate to form methamidophos and reacting the methamidophos formed with acetic anhydride to form N-(methoxy-methylsulfanylphosphoryl) acetamide is also described. Throughout the process, the O,O-dimethyl phosphorochloridothioate and the O,O-dimethyl phosphoroamidothioate formed are maintained in solution in CH2Cl2 at all times.

摘要： A flucarbazone sodium hemihydrate method and composition. A method of suppressing growth of grass and broadleaf weeds is described including applying to said weeds at least one dust-free composition comprising flucarbazone sodium-hemihydrate as an active ingredient. A method for preparing flucarbazone sodium-hemihydrate is also described including treating 4,5-dihydro-3-methoxy-4-methyl-5-oxo-N-[[2-(trifluoromethoxy)phenyl]sulfonyl]-1H-1,2,4-triazole-1-carboxamide (MSU) with aqueous sodium hydroxide under pH-controlled conditions; and confirming that a hemihydrate flucarbazone sodium has been obtained.
