Synthesis method
Composed of diethyl adipate or dimethyl adipate in the presence of metallic sodium, ethanol or in the presence of lead chromium oxide It can be obtained by catalytic reduction under the condition of catalytic reduction, or by catalytic reduction of 2,4diyne-1,6-diol. For example, hydrogenation reduction of diethyl oxalate. The catalyst for the above reaction is copper chromite, the hydrogen pressure is 3.79-20.68 MPa, the reaction temperature is 255°C, and the product yield is 85%-90%.
