Abstract: Disclosed is a method for producing a primary amine compound represented by the formula (2) below, which is characterized in that a halogen compound represented by the formula (1) below, ammonia and formaldehyde are reacted with each other, and then the thus-obtained reaction product is [1] brought into contact with an aqueous solution of an acid or [2] reacted with a hydroxylamine under acidic conditions. By this method, a primary amine compound can be commercially advantageously produced by using a low-cost ammonia while suppressing production of a secondary amine as a by-product. (1) (In the formula, R1 and R2 independently represent a hydrogen atom, a C1-C5 alkyl group which may be substituted by a halogen atom or the like, a C1-C5 alkoxy group which may be substituted by a halogen atom, a cyano group, a C2-C11 alkenyl group or a phenyl group or the like; R3 represents a hydrogen atom, a linear or branched C1-C5 alkyl group or a cyano group; and X represents a halogen atom.

Abstract: This invention provides an improved process for the preparation of chloroalkynes from alkynyl alcohols. The chloroalkynes can be employed to prepare alkynyl amines which are useful for the manufacture of biologically active materials. The present invention reduces the hazards of the chlorination reaction, eliminates or greatly reduces by-product formation, and provides certain environmental benefits.

Abstract: The process of this invention comprises a two step sequence wherein an alcohol is converted to an organic chloride through reaction with a chlorinating agent in a first step followed by amination of the organic chloride to the corresponding amine in a second step. In the second step, a surfactant is employed in order to facilitate the reaction.

Abstract: An allyl amine compound such as an allyl dialkyl amine is prepared by the reaction of ammonia or a water soluble amine with an allyl halide in the presence of an alkali metal or alkaline earth metal hydroxide or carbonate using a two-phase reaction system comprising water and a water-immiscible organic liquid. The allyl amine product is of an exceptionally high purity and contains relatively small amounts of salts. When the reaction method is employed to prepare an allyl dialkyl amine, the allyl dialkyl amine can effectively be quaternized to prepare a pure diallyl dialkyl ammonium compound at high yields.

Abstract: This invention relates to the preparation of amines by the reduction of imines with phosphorous acid, preferably under basic conditions.

Abstract: The invention is a process for reducing residual organic chloride in a hydrocarbyl amine by contacting the hydrocarbyl amine with a chlorine-displacing nucleophile selected from NaSCN, NaCN, and NaSPH where a portion of the residual organic chloride is converted to an inorganic chloride, and removing the inorganic chloride.
