| titleOfInvention | Method for producing coumarin and its derivatives |
| abstract | (57) [Summary] [Objective] In a method for producing coumarin and its derivatives by cyclodehydrogenation of 3- (2-cyclohexanoyl) propionic acid esters, while increasing the yield of coumarin and its derivatives, The purpose is to reduce the residual amount of the raw material, that is, to increase the conversion rate, to the extent that it does not cause an offensive odor when mixed in the product. [Structure] When coumarin and its derivatives are produced by cyclodehydrogenation of 3- (2-cyclohexanoyl) propionic acid esters, the reaction temperature and stirring power are increased in the latter half of the reaction in the latter half of the reaction.
