高纯度柠檬黄的研制

Study in synthesis of high-purity tartrazine

本文对柠檬黄商品做了有机杂质的定性分析。并在此基础上综合运用在线跟踪控制、相转移催化、膜分离等新技术，研制出高纯度柠檬黄，质量达到了美国食用化学品法典（FCCV）柠檬黄标准。

In this paper, the organic impurities in commercial Tartrazine are qualitatively analyzed, and on the base of it, High - purity Tartrazine is developed, which has the quality reaching the criterion of FCC V, by applying the techniques of on - line tracking, phase transfer catalysis and membrane separation.
