Using 100% ethanol and ice cold acetic acid to make stock solutions recommended by your company doesnot give any problem for the product to be dissolved. However, because limonin slightly dissolves in water, is it possible that there will be crystal of the product when we prepare the working solution from the stock while exceeding the solubility. If there is such effect on the research result, are there any solutions for it? According to research articles, the IC50 of limonin in cell model is around 100ug/ml, the effective concentration in animal model are way higher!

产品用贵公司推荐的100％乙醇或冰醋酸作为融媒配成母液时并不存在溶解的问题，但当母液进一步配制工作液时由于Limonin微溶于水，若超出溶解度范围是否将有结晶析出，如有将会影响研究结果，应该如何解决该问题（注：根据文献报道细胞模型Limonin的IC50约在100ug/ml左右，动物模型有效作用浓度将更高！

用氯化反应与熔融结晶耦合装置，进行乙酸氯化与产物氯乙酸的结晶分离，避免了 MCA 的深度氯化，从而提高了 MCA 的收率。

The possible mechanism was discussed. These bowl-shaped aggregates are promising candidates for nano reactor or drug carrier.4 2,7-dimethylene-1,4,6-trioxaspiro[4, 4]nonane with two vinyls was prepared to be used as electron-donor and crosslinker. The ATRP of this crosslinker and excess methylacrylate (used as electron-accpetor) was proved to mainly form homopolymers.
