| titleOfInvention | A kind of process of ester ammonia exchange process coproduction oxamides and carbamate |
| abstract | The invention discloses a kind of ester ammonia exchange process coproduction oxamides and the process of carbamate, the present invention, by a series of ester ammonia exchange reactions, can simultaneously obtain oxamides and two kinds of products of carbamate with urea, oxalate diester as raw material.The problems such as technique solves single product in original oxalate diester ammonolysis synthesis oxamides technology and urea alcoholysis synthesis of carbamates technology, accessory substance influence reaction process.Further, since urea is through CO 2 And NH 3 Synthesis is obtained, and the technique replaces NH with urea 3 , to CO 2 Change into the efficient using with positive effect of high added value value chemicals. |
