In a 1-litre flask fitted with a stirrer, a reflux condenser and a thermometer, a mixture of 63.2g potassium permanganate and 500g water is heated to 70 ° C under agitation. Then, 240g of aqueous solution dissolved with 96.2g of manganese sulfate and 40g of 15% sulfuric acid was added to the mixture and the contents were kept at 70 ° C for 3 hours for the reaction. After cooling the contents, the sediment is drained and washed with 2.4 litres of water. The precipitated cake was dried overnight at 60℃ to obtain 74g of activated manganese dioxide, which was used as the catalyst for the subsequent reaction. Add 150g of acetone cyanohydrin 1,350g of water, 100g of acetone and 60g of manganese dioxide obtained in this step in sequence to a 1-litre flask fitted with a stirrer, a reflux condenser and a thermometer. The contents are kept at 60 ° C for 5 hours under agitation for reaction. After cooling, the resulting solution is extracted and filtered to remove the catalyst. The results of gas chromatography showed that the conversion rate of ACH was 99.5%, the yield of α-hydroxyisobutylamide was 95%, and there were a small amount of acetone and formaldehyde in the filtrate.
