production method | 1. Tobacco: FC,9. 2. Preparation Method: In a dry reaction bottle equipped with a stirrer, a vent tube, a reflux condenser (a calcium chloride drying tube) and a dropping funnel, 5.5g of magnesium bar (0.23mol) was added and the mixture was covered with anhydrous ether. 1-bromodecane (66G, 0.2mol) and 70ml of dry diethyl ether were added to the dropping funnel and mixed well. About 5ml was added, followed by 0.5ml of methyl iodide to initiate the reaction. After the start of the reaction, the remaining 1-bromodecane solution was slowly added dropwise. The addition was completed for about 3H and then refluxed for 3H. After cooling, 50ml of diethyl ether was heated again, and ethylene oxide (2) was introduced under cooling in an ice-salt bath. The reaction was exothermic, and the reaction system gradually became viscous until stirring was impossible, and the passage of ethylene oxide was stopped. At this time, a large amount of magnesium compound crystals are precipitated and a large amount of heat is released. Dilute hydrochloric acid decomposition products were added and heated in a water bath to separate the oil layer. The aqueous layer was extracted with benzene. Merge oil layer and benzene layer. Cooling crystallization. After filtration and drying, about 20g of 1-Eicosanol (1) was obtained. The product can be used as a solvent for benzene recrystallization purification, can also be vacuum distillation purification, collecting 213~216 deg C/1.5kPa fraction. [1] |
