Method for carrying out the catalyst-free production of o-alkyl-n-cyanoformimidates |
| abstract |
The invention relates to a method for producing O-alkyl-N-cyanoformimidates, during which the reaction of cyanamide with orthoformic acid alkyl esters ensues with a molar ratio of 1: 0.8 to 10.0 without the addition of a catalyst, at pressures ranging from 0.1 to 10 bar, and at a temperature ranging from 40 to 180 °C. It is advantageous to remove alkanol formed during the reaction from the reaction mixture and to work, by and large, without using solvents. The product is obtained in very good yields and with utmost purity in a technically simple manner under environmentally friendly conditions. |
