The reduction of trihalomethane formation potential was discussed, which indicated that ozonation has a good removal for chlorofom and bromodichloromethane formation potential, but for dibromochloromethane formation potential the removal efficiency was undesirable and there was almost no removal for bromoform forming potential, Furthermore, when there was enough bromide in water, ozonation would have a promotion effect for bromoform formation potential.
通过研究臭氧对三卤甲烷生成潜能的去除规律发现，臭氧对三氯甲烷和二氯一溴甲烷生成潜能都有很好的去除，对一氯二溴甲烷生成潜能的去除效果较差，对溴仿生成潜能基本没有去除。当水中溴化物含量较高时臭氧对溴仿的生成反而具有促进作用。

According to the Box-Benhnken design principle,the method of response surface method with 3 factors and 3 levels was used. The factors influencing the technological parameters were determined by means of regression analysis. Response surfaces were finally graphed with the yield as the response value. The synthesis conditions were optimized as follows:reaction reagent was NBS,stoichiometric proportion between NBS and anhydrovinblastine was 1.07; the dosage of TFA was 22 mL/L; reaction temperature was －68 ℃ and duration was 90 min.
在单因素实验基础上，根据Box-Benhnken实验设计原理，采用三因素三水平的响应面分析法，研究了各个因素及其交互作用后，得到了合成7′-Br-脱水长春碱的最佳工艺条件：以二氯甲烷为溶剂，采用NBS为溴代剂，其用量与底物的物质的量比为1.07∶1，TFA的加入量22 mL/L，在－68 ℃下反应90 min，终止反应后，得到卤代产物。
