Název v původním jazyce

Hydrogenolysis of dimethyl adipate over copper oxide-zinc oxide-alumina catalysts

Popis výsledku v původním jazyce

Hydrogenolysis of organic esters to alcohols is commonly performed using Adkins catalysts based on copper and chromium oxides. However, as a result of an increasingly tightening environmental legislation, efforts are being made to replace the catalysts containing undesirable chromium by an environmentally-friendly option. Hence, this study is focused on determining the activity of an alternative CuZnAl catalyst in the hydrogenolysis of dimethyl adipate and the selectivity of the reaction to hexane-1,6-diol. The catalyst was tested in a flow reactor over a temperature range of 145-190 °C under a hydrogen pressure of 16 MPa. All reaction intermediates and products were identified by GC-MS. The influence of time-on-stream on the conversion of dimethyl adipate was also investigated. The study showed that at the maximum temperature of 190 °C it is possible to obtain a conversion of about 79%.
