| titleOfInvention | Improvements in or relating to the manufacture of dimethylformamide |
| abstract | Dimethylformamide is produced by mixing calcium formate with an aqueous solution of dimethylamine sulphate, removing the calcium sulphate formed, and heating to distil off the water and cause amide formation. The reactants are preferably mixed in stoichiometrically equivalent quantities, the dimethylamine sulphate being obtained by absorbing dimethylamine in dilute sulphuric acid. The product is recovered mainly from the distillation residue, but also from the aqueous distillate. The amount of water in the system may be from 200 to 300 grams per gram molecule of calcium formate used. |
