    摘要: A C. I. Solvent Orange 63 with reduced corrosive behavior during the processing in plastics can be obtained by controlling the residual amount of organic bromine in by-products resulting from di-bromo content of the raw material.The C. I. Solvent Orange 63 thus obtained is negative in mutagenicity and sensititzation tests, allowing an improved industrial hygiene during handling and processing and a safer end use in regulated end uses such as the coloration of consumer goods, food packaging and toys.
