- W2370698073 abstract "With anhydrous magnesium sulfate packed in Soxhlet extractor as de hydrant,and cation exchange resin as catalyst,diethyl malonate was first synthe sized by esterification of malonic acid with ethyl alcohol.The catalyst had hig h activity,no corrosion to the facilities,reaction product separated easily and no waste acid discharged.It was an environmentlly friendly catalyst.The reacti on conditions of esterification were studied.The optimum condition was obtained as follows: malonic acid 0.2mol,ethyl alcohol 0.6mol,catalyst 1.5g,reaction ti me5h,anhydrous magnesium sulfate 8g.The conversion was 95.5% under the optimum conditions." @default.
