Method for the preparation of storage-stable 3-methylmercaptopropionaldehyde |
| abstract |
Process for the preparation of 3-methylmercaptopropionaldehyde by reaction of acrolein with methylmercaptan, wherein impurities and by-products from the reaction of acrolein with methylmercaptan are removed by distillation, characterized in that the reaction is carried out in the presence of a basic amine, the basic amine has a pK b smaller than 8, that prior to distillation, the basic amine is neutralized by adding an acid and that the acid has a pK s less than 5 and a vapor pressure less than 10 hPa at 20 ° C. |
