Reaction Conditions:
with sodium ethanolate at 105 - 110; for 8 h;Large scale;
Steps:
1 The present invention is carried out according to the following stepsPreparation of R-propylene carbonate
R - Preparation of propylene carbonate,R-1,2-propanediol was added to a glass-lined reactor(38.05 kg, 500Mol),Diethyl carbonate(70.88 kg, 600 mol) and (3.4 kg, 50 mol) of sodium ethoxide,Heated to 105-110 ° C,Reaction for 8 hours,The reaction is terminated,The unreacted diethyl carbonate was distilled off under reduced pressure,Cooled to room temperature,Filter insoluble matter,The filtrate was evaporated to remove the solvent of product R - propylene carbonate 34.24 kg,Purity ≥ 99%The yield was 90%.
