Abstract

The present study describes a rapid and novel method for the synthesis of two monoazo MORDANT DYEs. In this method, diazonium salt (ArN2+ -CrO3-SiO2) was prepared via grinding of 2-amino benzoic acid as diazo component, NaNO2, wet SiO2 and nano silica chromic acid without solvent at room temperature. The obtained diazonium salt was sufficiently stable to be kept at room temperature in the dry state. AZO DYEs were prepared by coupling of (ArN2+ -CrO3-SiO2) with 1 and 2-naphthoxide as coupling components, in good to excellent yields. The analytical methods such as FT-IR, 13CNMR and 1HNMR were used for identification of two synthesized dyes. Synthesized monoazo MORDANT DYEs were applied to DYEING wool in after chrome method. The chromaticity co-ordinations and wash fastness of samples were measured. The results showed that the hues of both dyed and mordanted samples are the same and their wash fastnesses are 3. J.
