The comparison of the course of hydrogenolysis performed in protic solvent as a source of hydrogen in situ with hydrogenolysis carried out in the presence of molecular hydrogen was made. As a donor of hydrogen molecule 1- and 2-propanol were used. Hydrogenolyses with hydrogen generated in situ were conducted using two methods: under inert gas pressure (nitrogen) and pressureless ? in the absence of inert gas and molecular hydrogen.
Introduction
Biodiesel production based on transesterification of vegetable oils with methanol or ethanol provides large amounts of waste glycerol, containing about 30?80 %wt of glycerol [1]. For every 10 kg of biodiesel produced, about 1 kg of waste glycerol is formed [2]. Therefore, there is a need to manage the glycerol contained therein. Firstly, the methods of manufacturing glycerol to more valuable chemical compounds have been sought. One such method is hydrogenolysis of glycerol to 1,2-propanediol....
