| titleOfInvention | The method of synthesizing alcohol acid esters |
| abstract | The present invention relates to a kind of methods of synthesizing alcohol acid esters, mainly solve that the technical issues of ethyl glycolate yield is low exists in the prior art.The present invention mixes it by using using the oxalate containing part carbonic ester as reaction raw materials with hydrogen in advance, and then in 150~240 DEG C, 0.5~4MPa of reaction pressure of reaction temperature, oxalate weight space velocity is 0.1~3 hour ‑1 , hydrogen and oxalate molar ratio are (10~160)：It is contacted under conditions of 1 with the catalyst crossed through temperature programming hydrogen reducing and carries out hydrogenation reaction, obtain the product containing ethyl glycolate；Wherein catalyst by weight percentage, including following components：1) 0.5~25wt% silver or its oxide；2) at least one of the IVth B races of 0~20wt% metal or its oxide；3) technical solution of 62~99.5wt% silica supports；Preferably solves the problems, such as this, in the industrial production available for preparing ethanol by oxalate hydrogenation acid esters. |
