Description

Benzothioxanthene dicarboxylic anhydride is a synthetic polymer that is used as a colorant in the textile industry. It has been shown to be lightfast and to have good chemical stability, as it can resist decomposition even at high temperatures. Benzothioxanthene dicarboxylic anhydride is also chemically stable when exposed to alcohols and stabilizers. The molecule is low molecular weight, which means it can be easily polymerized into a long chain of molecules. The polymerized form of benzothioxanthene dicarboxylic anhydride is used to make cellulose acetate, which is widely used in the production of paper and textiles.
