-
, (2008/06/13)
A hair cosmetic which can impart, to hairs, flexibility, smoothness and oily feeling when the hairs are wetted and smoothness, softness and combing easiness after the hairs are dried are provided, the hair cosmetic comprising an amine represented by the formula (I): Formula (I) (wherein R1 represents a C8-40 alkyl group or alkenyl group or a group represented by the formula R5O—(AO)n—CmH2m— (R5 represents a C8-40 alkyl group or alkenyl group having 8 to 40 carbon atoms, A represents a C2-3 alkylene group, n denotes a number from 0 to 30 in average and m denotes an integer of 2 or 3), R2 represents a C1-5 alkylene group, R3 represents H, a C1-24 alkyl group, alkenyl group or hydroxyalkyl group or a C6-28 aryl group or arylalkyl group, R4 represents H, a C1-5 alkyl group, alkylene group or hydroxyalkyl group or a C6-28 aryl group or arylalkyl group, p denotes an integer from 1 to 3, q and r denote integers from 0 to 2 and p+q+r is equal to 3. Also, the amine (I) can be produced with high selectivity and highly economically by reacting a primary amine with an aminocarboxylic acid to run amidation. An amine represented by the formula (1), its salt or quaternary ammonium salt are also provided: Formula (1)
Process for production of ether amine
-
Example 1; comparative 1, (2008/06/13)
Disclosed herein are a process for producing an ether amine(3), which comprises reacting a primary or secondary alcohol(1),ROH, with acrylonitrile in an amount of 0.8 to 1.2 equivalents of the alcohol(1) in the presence of an alkali metal hydroxide in an amount of not less than 0.01 part by weight, but less than 0.05 part by weight per 100 parts by weight of the alcohol(1) to obtain an alkyloxypropionitrile(2),and then adding water to the reaction system without removing the alkali metal hydroxide therefrom and effecting hydrogenation using a hydrogenation catalyst:ROH(1)+ CH2=CHCN, ROCH2CH2CH2CN(2), ROCH2CH2CH2NH2(3) wherein R denotes a linear or branched alkyl or alkenyl group having 6 to 24 carbon atoms. Also disclosed are a process for producing an ether tertiary amine (5), R-O-CH2-CH2-CH2-N(CH2R1)2, which comprises adding an aldehyde to the resulting ether amine(3) in the presence of a metal catalyst or a Raney nickel catalyst, and a process for producing an ether quaternary ammonium salt (6), R-O-CH2-CH2-CH2-N(CH2R1)2(R2), which comprises reacting a quaternizing agent with the ether tertiary amine(5).
