Abstract
18-Crown-6 was used as a catalyzer for the monobenzylation of 1,9-nonanediol at a mild condition.By optimized the reaction temperature and the equivalent of KOH or benzyl bromide,an entry consisted 1.5 mol equivalent of KOH,0.95 mol equivalent of benzyl bromide and within 0~-5 ℃,was considered as the ideal condition,which has the most product and fewer dibenzylated compound.
