Yield:95-92-1 99.3%

Reaction Conditions:

with enriched hydroxylated graphene oxide in benzene at 120 - 140;

Steps:

4 Example 4

Example 4 400 ml of 98% sulfuric acid was maintained at a temperature of -2 ° C,Add 10 ml of 30% hydrogen peroxide,After incubation for 30 min,Followed by adding 0.6g graphite powder,3.6g sodium perchlorate;Then 20 insulation 1-3h,Centrifugation to obtain hydroxylated graphene oxide;In 1000ml four bottles,Respectively, put oxalic acid,Ethanol,benzene,200 g of enriched graphene oxide, 220 g, 20 g, 1 g,The reaction temperature is controlled atBelow 120 ,Until there is no water out,Continue to heat up to 140 ° C,Distilled benzene,The benzene is distilled off.Cooling the separation of diethyl oxalate,Hydroxylated graphene oxide,The yield of diethyl oxalate was 99.3%.
