[中文文摘]蜂蜡或糠蜡用乙醇处理,然后用碱醇在苯中皂化,由蜂蜡所得不皂化物再经戊醇-盐酸提取,中层用苯重结晶;由糠蜡所得不皂化物用丙酮萃取后真空分馏,其一馏份也用苯重结晶,两者都得白色鳞片状晶体(m.p.85.5—56.5℃)。其乙酰化物用乙醇重结晶得白色片状晶体(m.p.69—70℃)。元素定量分析及红外光谱分析表明:该物质是三十烷醇-1。[英文文摘]Bees-wax or Bran-wax is treated with alcohol and then saponified with alc. alkali in benzene. The unsapontficd substance from been-wax is extrated with amyl alcohol-HCL and the middle layer recrystallized from benzene. The unsaponif ied substance from bran-wax is extracted with acetone, the extr-actact after removal of acetone is vacuum-fractionated, one of the distillates also recrystallized from benzene. Both give white scale-like crystals m. p. 85.5-86.5℃. The acetylated derivative is recrystallized from alcohol to give white plate-like crystals.m.p.69-70℃.Elemental quantitative analysis and IR spectral analysis show the substance to be 1-triacontanol.
