9-bromo-1-nonanol CAS 55362-80-6

9-Bromo-1-nonyl cawv yog ib qho organic intermediate uas tuaj yeem tau los ntawm bromination los ntawm 1,9-nonediol ua cov khoom siv raw. Nws tau raug tshaj tawm tias nws tuaj yeem siv los npaj cov pheromone sib deev ntawm Spodoptera litura. Npaj thiab ntxiv 40g ntawm 1,9-nonediol, 550ml ntawm toluene, thiab 35ml ntawm 48% HBr aqueous kua rau hauv lub thawv. Do thiab reflux rau 12 teev, ntxiv 8ml ntawm 48% HBr aqueous kua, reflux rau 15 teev, txias rau chav sov, dilute nrog n-hexane, ntxuav nrog saturated NaHCO3 kua thiab dej ntsev, qhuav nrog anhydrous Na2SO4, thiab distill nyob rau hauv txo qhov siab kom tau txais cov kua tsis muaj xim pob tshab 9-bromo-1-nonol.
