Method for producing coumarins |
| abstract |
(57) [Summary] [Object] An object of the present invention is to provide a method having a high reaction rate in producing coumarins from 3,4-dihydrocoumarins. [Structure] When producing coumarins by dehydrogenation of 3,4-dihydrocoumarins in the presence of a metal catalyst, the heating amount per unit reaction liquid amount for evaporating the reaction liquid is 80 to 1000 kcal / kg. It is characterized in that it is performed in hr. |
