Adding a certain compound to certain chemical reactions, such as: 10160-24-4, 7-Bromo-1-heptanol, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, Recommanded Product: 7-Bromo-1-heptanol, blongs to alcohols-buliding-blocks compound. Recommanded Product: 7-Bromo-1-heptanol
A method for synthesizing cis-7-tetradecenol acetate, which is the main sex pheromone of the elm moth, comprises the following steps:(1) Preparation of (7-bromoheptyl-1 -) – 2-tetrahydropyranyl ether To a 500 ml four-necked flask equipped with an electromagnetic stirrer, a reflux condenser,Pressure dropping funnel in a 250 mL four-necked flask, 3,4-dihydropyran 8 g was added and 0.03 g of 37% hydrochloric acid was added as a catalyst with stirring. After 10 min, a solution of 7-bromo- Alcohol 17 g, control the dropping rate (the reaction is exothermic reaction, 7-bromo-1-heptanol dropping speed is accelerated, the reaction is accelerated, exothermic increase, to be ice bath cooling), keep the reaction temperature of 40 ~ 60 C, add room temperature after reaction 2 h, stop stirring, instead of distillation device, steamed unreacted 3,4-dihydropyran. After the residue was cooled, 85 g of petroleum ether was added, washed with saturated sodium hydrogencarbonate solution and saturated brine, dried over sodium sulfate for 10 to 15 hours, concentrated and evaporated to give (7-bromoheptyl-1- Tetrahydropyranyl ether 23.5 g, purity 99.2%, the yield was 96.7%.
At the same time, in my other blogs, there are other synthetic methods of this type of compound,10160-24-4, 7-Bromo-1-heptanol, and friends who are interested can also refer to it.
