    Abstract: A novel quaternary ammonium salt fit for a softening basis which excels in softness and enjoys high biodegradability and a liquid composition of softener composition exhibiting fully satisfactory quality in terms of softness and stability in storage, excelling in biodegradability, and behaving gently to the natural environment. A quaternary ammonium salt represented by the general formula (1), a liquid composition of softener composition comprising 3 to 40% by weight of the quaternary ammonium salt and the balance of water, and a method for the production of the composition: (wherein R , R , and R stand for an alkyl group or hydroxyalkyl group of 1 to 4 carbon atoms, R and R stand for an optionally hydroxyl group-substituted linear or branched alkyl group or alkenyl group of 8 to 36 carbon atoms, A stands for a linear or branched alkylene group of 2 or 3 carbon atoms, X stands for an anion group, n stands for an integer in the range of 1 to 6, and m stands for a numeral in the range of 0 to 20).

    Abstract: To provide processes suitable for industrial production by which high-purity N-(long-chain acyl)amino acid and salt thereof can be prepared from inexpensive raw materials. An alkyl ester of a fatty acid (2) is reacted with an aminonitrile (3) in the presence of a basic catalyst to form an amidonitrile (1), the amidonitrile (1) is hydrolyzed into an N-(long-chain acyl)amino acid salt (4) in the presence of a basic substance, the pH of the resulting aqueous solution is adjusted to a pH from 1 to 5 with a mineral acid to form an N-(long-chain acyl)amino acid (5), and this amino acid is recovered. wherein R CO- represents a fatty acid residue having 8 to 22 carbon atoms; R represents a hydrogen atom or an alkyl group having 1 to 3 carbon atoms; R represents an alkylene group having 1 to 5 carbon atoms; R represents an alkyl group having 1 to 4 carbon atoms; and M represents a monovalent cation.

    Abstract: Prepn. of aliphatic prim. amine comprises reacting a 8-24C aliphatic nitrile with hydrogen at 150-250 deg.C and a hydrogen pressure of 1-50 atm. in the presence of a hydrogenation catalyst and either an alkali metal hydroxide or ammonia. The catalyst contains (a) Cu, (e) a gp.VIII Pt metal and/or (f) a IV period transition metal (not Cu) in a wt. ratio (a/e) of 1/0.0001 to 1/0.1 and (a/f) of 99/1 to 10/90. The catalyst can also contain (c) an alkali or alkali earth metal in a wt. ratio (a/c) of 1/1 to 1/0.01 and (d) at least one metal selected from Al, Mo and W in a wt. ratio (a/d) of 1/1 to 1/0.1.
