Abstract

1,272,884. Amines. UGINE KUHLMANN. 13 March, 1970 [14 March, 1969], No. 12063/70. Heading C2C. [Also in Divisions C4-C5] The Na salt of N-ethyl-N- ( 2<SP>1</SP>-p-sulphophenoxyethyl) - m - toluidine is prepared by condensing 2 - bromo - ethoxy - benzene with N - ethylm - toluidine to yield N-ethyl-N-(21-phenoxyethyl) - m - toluidine which is sulphonated and isolated as the Na salt: the Na salt of N-ethyl- N - (2<SP>1</SP>- p - sulphophenoxy - ethyl) - o - toluidine and N ethyl - N - (21 - phenoxyethyl) - mtoluidine are similarly prepared.
