What is 3-Hydroxy-2-naphthoic acid?
3-Hydroxy-2-naphthoic acid is a natural substance with the chemical formula C 10 H 6 (OH) (CARBON MONOXIDE 2H). It is among a number of carboxylic acids derived from 2-naphthol. It is a common precursor of azo dyes as well as pigments. It is prepared by carboxylating 2-naphthol via the Kolbe Schmitt response.
3-Hydroxy-2-naphthoic acid is a forerunner of numerous anilines, such as Naphthol AS, which responds with diazonium salts to develop dark azo substances. The azo coupling of 3-hydroxy-2-naphthoic acid additionally creates numerous dyes.
3-Hydroxy-2-naphthoic acid Uses
3-Hydroxy-2-naphthoic acid is generally utilized as an intermediate in the production of dyes and pigments. Additional use is as an intermediate for insecticides and drugs (ECB, 2000).
2-Hydroxy-3-naphthoic acid (BON) is combined with diazo substances, and its calcium salt is a bright red impermeable pigment. Manganese salts with somewhat greater costs show far better exterior toughness than calcium or barium salts. The attributes of BON red pigment are high shade security, acid as well as alkali resistance, and also safe.
