提出以2mol/L KBr-冰醋酸(1:3 V/V)为电解液,在阳极电生溴与茄尼醇发生反应来测定茄尼醇含量的库仑滴定法.茄尼醇与溴反应,其n值为18.对于烟叶提取物中茄尼醇,以正已烷-二氯乙烷-丙酮为展开剂,用薄层色谱法予以分离,用库仑滴定法进行测定.
A coulometric titration method was proposed for the determination of solanesol with the reaction of 2mol / L KBr-glacial acetic acid (1: 3 V / V) as electrolyte at the anode and the reaction of sobrinol with solanesol.The reaction of solanesol with bromine, The value of n is 18. For the solanesol in tobacco extract, n-hexane-dichloroethane-acetone was used as the developing solvent, and was separated by thin layer chromatography and determined by Coulometric titration.
