The present invention relates to a process for the preparation of a Cto Cwax from the thermal decomposition of plastic polymer. The present invention provides a vacuum pyrolysis process for preparing a Cto Cwax from the thermal decomposition of plastic polyolefin polymer, the method comprising the steps of: i) introducing plastic polyolefin polymer into a thermal reaction zone of a vacuum pyrolysis reactor; ii) heating the plastic polyolefin polymer at sub-atmospheric pressure, wherein the temperature in the thermal reaction zone of the reactor is from 500° C. to 750° C., to induce thermal decomposition of the plastic polyolefin polymer and to form a thermal decomposition product effluent which comprises a major portion by weight of a Cto Cwax fraction; and iii) condensing a vapour component of the thermal decomposition product effluent from the vacuum pyrolysis reactor in a multistage condensation comprising a plurality of condensation stages connected in series.

This invention relates to a process for the preparation of glycerol carbonate from the reaction of glycerol and a dialkylcarbonate, for example dimethyl carbonate, or a cyclic alkylene carbonate. More specifically, the invention relates to a process where the synthesis of glycerol carbonate is conducted in the presence of a homogeneous transesterification catalyst and involves the partial reaction of a glycerol reactant stream and a dialkyl carbonate or cyclic alkylene carbonate reactant stream and an intermediate step of alcohol by-product separation before further reaction in order to improve glycerol conversion and glycerol carbonate selectivity and yield.
