3-Amino-4-carboalkoxy-benzoic acid 4{40 -phenoxy-anilides |
摘要 |
3-Amino-4-lower carboalkoxy-benzoic acid-4'-phenoxy-anilides which may be halogenated in the phenoxy nucleus are obtained by reacting the corresponding 4-carboalkoxy-benzoyl chlorides having in 3-position a group capable of yielding the amino group with a 4-amino-diphenyl ether which may be halogenated in the phenyl nucleus which is not substituted by the amino group, and setting free the amino group from the group capable of yielding it. The products are diazo components for azo pigments, especially of the 2-hydroxy-3-naphthoic acid arylide type.
