| titleOfInvention | Efficient method for producing carbonic acid diester |
| abstract | PROBLEM TO BE SOLVED: To stably perform a reaction operation over a long period of time in a method for producing a carbonic acid diester using a catalyst solution containing a copper catalyst, while avoiding the problem of solids that may cause catalyst deterioration. Provide a way to A method for producing a carbonic acid diester using a catalyst solution comprising a homogeneous solution in which a copper catalyst is present in a dissolved state, comprising: (i) a reaction step of reacting an organic hydroxy compound with carbon monoxide and oxygen in the catalyst solution; (Ii) separation for separating at least a part of the carbonic acid diester from a part or all of the reaction product liquid containing the carbonic acid diester, by-product water, unreacted organic hydroxy compound and the catalyst liquid extracted from the reaction step (Iii) from a part or the whole of the reaction product liquid extracted from the reaction step or the remaining liquid after at least part of the carbonic diester is separated from the reaction product liquid; A solid separation step of separating solids present in the liquid, (Iv) a circulation step of circulating the liquid after separating the solid obtained in the solid separation step to the separation step or the reaction step; A method for producing a carbonic acid diester, comprising: |
