| titleOfInvention | Method for producing rhodamine dye |
| abstract | (57) Summary [Objective] The present invention relates to a novel method for producing an alkyl esterified rhodamine dye. [Structure] A dye base obtained by a condensation reaction of phthalic anhydride and N-substituted-m-aminophenol is used with a dialkyl sulfuric acid in the presence of one or more solvents selected from dialkyl ketones and cellosolves. A method for producing an alkyl-esterified rhodamine dye, which comprises performing esterification. [Effects] According to the method of the present invention, the target alkylesterified rhodamine dye and its double salt can be industrially advantageously produced in high yield and high purity by an industrially easy method. it can. |
