| titleOfInvention | Method for producing chromancarboxylic acid |
| abstract | (57) [Problem] To provide a method for easily and smoothly producing a chromancarboxylic acid industrially with high productivity using easily available raw materials and inexpensive raw materials. . A dialkylphenol compound, formaldehyde and an alcohol are reacted in the presence of a secondary amine and an acid to obtain an alkoxymethylated phenol compound (first step). Reacting with an ester having a carbon double bond at a temperature of 100 ° C. or higher to obtain a dialkyl chroman carboxylic acid ester (second step), hydrolyzing the obtained dialkyl chroman carboxylic acid ester to convert the dialkyl chroman carboxylic acid to A method for producing chromancarboxylic acid, comprising reacting the obtained dialkylchromancarboxylic acid with an aromatic hydrocarbon in the presence of a Lewis acid (fourth step). |
