| overview | monoethyl oxalyl chloride is a colorless and transparent liquid, volatile, deliquescent, with a boiling point of 135 ℃, and is used as a raw material for the synthesis of antibiotics, high-efficiency herbicides and organic chlorides. |
| use | for organic synthesis |
| production method | note! Operate in a fume hood. 1. Oxalic acid-ethyl vinegar-potassium 100 ml of water, 100 grams (1.02 mol) of potassium acetate and 143 grams (0.98 mol) of oxalic acid-ethyl vinegar are heated and stirred in a water bath until they are homogeneous, which takes about 4 hours. Evaporate to about 100 ml under vacuum, add 200 ml of ethanol and 600 ml of ether. Filter, collect oxalate monoethyl potassium. The filtrate is properly steamed and concentrated to obtain part of the potassium salt. The yield of oxalate-ethyl ester-potassium is 95-97%. 2. Ethyl oxalate-acid chloride 50g (0.32 mol) of the above-mentioned dried potassium salt is moistened with anhydrous ether, cooled in an ice bath, and 80g (0.67 mol) thiomethylphthalide chloride is added drop by drop. After the temperature rises to room temperature, it is heated and refluxed in a water bath for 15 hours. Filtration, washing and filtering with anhydrous diethyl ether, combining filtrate and washing solution, fractionation with a short fractionation column, collecting the fraction of Buddha point 125-138 ℃ as the product, with a yield of 60-70%. |
