Hydrogenolysis of dimethyl adipate over CuZnAl catalysts produces not only the desired hexane-1,6-diol, but also a number of by-products that have not been described so far. Catalytic experiments were carried out in a fixed bed reactor in the temperature range of 175–205 °C at hydrogen pressures of 10 and 16 MPa in the presence of a commercial CuZnAl catalyst. All reaction intermediates and products were identified by GC–MS and a reaction pathway of their formation via hydrogenolysis and transesterification was proposed. Upon evaluation of the role of the intermediates in dimethyl adipate conversion to hexane-1,6-diol it was established that the reaction by-products formed by transesterification affected the rate of hexane-1,6-diol formation.

在CuZnAl催化剂上进行己二酸二甲酯的氢解反应不仅会产生所需的1,6-己二醇己烷，还会产生许多迄今未描述的副产物。在商业化CuZnAl催化剂存在下，在固定床反应器中于175-205°C的温度范围内，在10和16 MPa的氢气压力下进行了催化实验。通过GC-MS鉴定了所有反应中间体和产物，并提出了它们通过氢解和酯交换反应形成的反应途径。在评估中间体在己二酸二甲酯向己烷-1，6-二醇转化中的作用后，确定了通过酯交换反应形成的反应副产物影响了己烷-1，6-二醇的形成速率。
