| titleOfInvention | Production of pure form 5-formylvalerate |
| abstract | (57) [Summary]nA mixture of 5-formylvalerate with either 3- or 4-formylvalerate or a mixture of 3- and 4-formylvalerate, wherein the ester group of each formylvalerate is To produce 90% or more by distillation of the same) from 5-formylvalerate to 3- and 4-formylvalerate or mixtures thereof (using the corresponding methyl or ethyl ester as the ester) By distillation at a pressure in the range from 2 to 100 mbar and at a temperature of 150 ° C. or lower (temperature measured at the bottom of the distillation column), whereby the purity of 5-formylvalerate is 98% or more. To produce 5-formylvalerate having an amount of 4-formylvaleric acid of 100 ppm or less as an impurity. |
