Patent number: 5705648Abstract: Mepiquat chloride is formed from the reaction between N-methylpiperidine and chloromethane in an anhydrous liquid solvent selected from the group consisting of acetone, methyl ethyl ketone, toluene, tetrahydrofuran, isopropanol, acetonitrile, N,N-dimethylformamide and methylene chloride in the absence of sodium hydroxide. Mepiquat chloride precipitates as a solid of high purity and is recovered under a substantially moisture-free atmosphere.The solid mepiquat chloride can be sealed into a water soluble pouch or into a water soluble encapsulated solid form (e.g., granule, pellet, or briquette) for convenient handling. The pouch contains powdered mepiquat chloride or the encapsulated solid is merely introduced directly into a spray tank or reservoir for application with low human exposure and no containers in contact with the mepiquat chloride that require disposal.Mepiquat chloride is used as a component of a system for growing a number of commodity plants including cotton.Type: GrantFiled: October 17, 1994Date of Patent: January 6, 1998Assignee: Micro Flo Co.Inventors: Richard U.
