摘　　要：以异丁醇、氢氧化钠、二硫化碳为原料,在溶剂二氯甲烷中合成异丁基黄原酸钠,经元素分析、核磁共振氢谱及碳谱、红外光谱分析,证实所得产物即为目标产物.考察了物料配比、溶剂用量、合成温度、合成时间等因素对产物纯度、产率的影响,得出优化工艺条件为:n[(CH3)2CHCH2OH]∶n(NaOH)∶n(CS2)=1∶1∶1.05,二氯甲烷用量为异丁醇体积的2.5倍,温度25℃左右,时间4 h,在此条件下,异丁基黄原酸钠的产率可达93.92%,纯度可达87.78%.Sodium iso-butyl xanthate is synthesized from isobutanol, sodium hydroxide and carbon disulphide with dichloromethane as solvent. The compound is characterized by elemental analysis, infrared spectrum, 1H NMR and 13C NMR. The influence factors on the product purity and yield including material ratio, solvent volume, reaction temperature and reaction time are studied. The results show that when n[（CH3）2CHCH2OH]： n（NaOH）： n（CS2）=1：1：1.05 ,reaction temperature is about 25 ℃ and reaction time is 4 hours, the product yield could be up to 93.92 %, and the product purity reaches 87.78 %.
