Title:
1-HALOPIPERIDINE DERIVATIVE AND N-HALO-HINDERED AMINE COMPOUND
Document Type and Number:
Japanese Patent JP2609996
Kind Code:
B2
Abstract:

PURPOSE: To obtain a new 1-halopiperidine derivative and an N-halo-hindered amine compound usable for blenching agent compositions capable of exhibiting excellent bleaching effect even at low temperature and causing no discoloration.
CONSTITUTION: A 1-halopiperidine derivative of formula I [R1 to R4 are alkyls; R5 and R6 are H; R1 and R2 or R3 and R4 may form a ring together with C; X1 is a halogen; Z is formula II, formula III or formula IV (Y is an alkoxy, etc.)], e.g. 1-chloro-4-[N-(2-hydroxyethyl) methyl-amino]-2.2.6.6- tetramethylpiperidine of formula V. A N-halo-hindered amine compound of formula VI(R24 is OH, a halogen, etc.,;X2 is a halogen), e.g. 3-(N-chloro-N- cyclohexylamino)-1,2-propanediol of formula VII. The compound of formula I is obtained as the objective N-halogenated compound by dissolving, e.g. an amine compound as a raw material in an inert solvent and adding a halogenating agent and as necessary, solid carbonic acid thereto.
