3. Usage:
1. ethyl anhydride method will be tert-butanol, ethyl anhydride and anhydrous zinc chloride mixing heating reflux 2h, then cooling, distillation to a temperature of 110 ° C, the crude distillate washed with water, and then washed with 10% potassium carbonate to neutral, anhydrous potassium carbonate drying, and then distillation, collection of 95-96 ° C fractions that is the finished product. 2. acetochlorine method will be tert-butanol, N, N-dimethylaniline and anhydrous ethyl ether mixing, heating reflux, and then add acetyl chloride, control the addition temperature, maintain a moderate reflux rate, add 2/3 of acetyl chloride, N, ChemicalbookN-dimethylaniline hydrochloride crystallisation, ice bath cooling, and then heated for 1h. The method of acetyl chloride is to mix tert-butyl alcohol, N,N-dimethylaniline and anhydrous ether, heat and reflux, then add acetyl chloride, control the charging temperature, maintain a moderate reflux rate, add 2/3 acetyl chloride, N,ChemicalbookN-dimethylaniline hydrochloride crystals, ice-bath cooling, and then heated for 1h. Add water to make the solids all soluble, separate the ether layer, extracted with cold 10% sulfuric acid, washed with saturated sodium bicarbonate solution for 1 time, drying with anhydrous sodium sulfate, and obtained the finished products by fractional distillation.3.Acetyl chloride-magnesium method will be Magnesium powder, terbutyl alcohol and anhydrous ether mix well, add acetyl chloride and anhydrous ether solution drop by drop, add cooling, add cold aqueous solution of potassium carbonate, so that the decomposition, extracted with ether for 3 times, drying with calcium chloride, distillation and finished products.
4. Packaging and storage:
Packaging specification: Packing specification: 25kg/drum, also can be determined according to user's need.
During transportation, it is necessary to protect against sunlight, rain, and high temperatures.
The product should be stored in a cool, dark, ventilated place, away from sources of fire.
5.Safety protection:
Pay attention to labor protection when handling it and avoid contact with skin, eyes, etc.After contact, rinse immediately with plenty of water
