摘要

THE year 1856 marked the beginning of synthetic colorants. In 1856 there were three events took place:1. C Greville Williams reported that 'quinoline', after quaternisation with methyl, ethyl or amyl iodide, gave rise to beautiful blue dyes on treatment with silver oxide 2.William Henry Perkin was following up on August Wilhelm Hofmann's suggestion concerning quinine synthesis in London. He obtained Mauveine 3.Natanson noted the formation of a red product during experiments with aniline - Fuchsine Earlier in 1771, Peter Woulfe prepared picric acid (PA), useful for dyeing wool and silk yellow and this was produced since the last decades of the 19th century. Prior to these findings the colorants obtained were of either mineral origin (the inorganic compounds), plant origin (such as indigo, madder) and animal origin (for example insect cochineal). Majority of the share came from inorganic minerals. The naturally occurring organic compounds like indigo, and hydroxy anthraquinones were embed in o=inorganic nano-materials in paintings.
