2-METHYL-4'-SUBSTITUTED-4-(4"-METHOXYCINNAMIC ACID)AZOBENZENE AND PRODUCTION THEREOF

Title:

2-METHYL-4'-SUBSTITUTED-4-(4"-METHOXYCINNAMIC ACID)AZOBENZENE AND PRODUCTION THEREOF

Document Type and Number:

Japanese Patent JPS61212549

Kind Code:

A

Abstract:

NEW MATERIAL:A compound shown by the formula I [R is CnH2n+1' or CnH2n+1O (n is 1W4)].

EXAMPLE: 2-Methyl-4'-methoxy-4-(4'-methoxycinnamyloxy)azobenzene.

USE: Useful as a stationary phase for a column of gas chromatography, etc. For example, effective for separating isomers of xylene or naphthalene substituted substance, cis- and trans-isomers, and conjugated double bond isomers which were not easily separated by a conventional procedure.

PREPARATION: An azo compound shown by the formula II is reacted with a 4-methoxycinnamic acid halide shown by the formula III (X is halogen, prefer ably Cl) under a dehydrohalogenating condition to give a compound shown by the formula I. The reaction is carried out in equimolar amounts and the amount of the compound shown by the formula III used is 1W2 times the molar amount of the compound shown by the formula II.
