| titleOfInvention | A kind of green preparation method of N,N-dimethylamino ethyl acrylate |
| abstract | The invention discloses a green preparation method of N,N-dimethylamino ethyl acrylate. The steps of the method include: in a carbonylation reaction kettle, ethyl acetate, sodium ethoxide and carbon monoxide are in a xylene solvent, and a catalyst acts as a catalyst. carbonylation reaction is carried out to obtain a reactant comprising ethyl formyl acetate sodium salt; the ethyl formyl acetate sodium salt in the reactant is then subjected to condensation reaction with dimethylamine hydrochloride to obtain N,N-dimethylaminoacrylic acid ethyl ester. The present invention uses tri-n-propylamine as a catalyst, reduces side reactions, and improves product yield; the carbonylation reaction kettle uses a self-priming stirring reaction kettle, which reduces side reactions and reduces the amount of by-product ethyl formate produced; and also The recycling of by-product ethyl formate and the recycling of catalyst tri-n-propylamine and solvent xylene are further realized. The invention improves the total yield of products, reduces side reactions, reduces the amount of three wastes treated, saves costs, and is more conducive to large-scale industrial production. |
