查询词典 chlorine

The distillation column with a single photochlorination reactor was built in this paper, which is used in the laboratory study. In light initiation, the semi-continuous operation was applied to study the influence of the chlorine flow, the reflux and the height of the packing on photochlorination of acetic acid. Crude MCA with a purity of 90% or more was attained and the feasibility of this technology was proved.

本文建立了适合实验室研究的背包式光氯化反应精馏耦合装置，采用半连续操作的方法，在光引发条件下，考察了氯气流量、回流量和填料高度对乙酸光氯化反应的影响，得到了含量达90％以上的氯乙酸粗品，证实了工艺的可行性。

Mixed chlorotoluenes photo-chlorination experiments in a loop reactor were made, the effects of chlorine flow, temperature and p-/o- chlorotoluene initial ratio on mixed chlorotoluenes photo-chlorination were researched. The relations between the concentration of each component and time under different conditions were measured. The rule and the suitable process parameters of the photochlorination of p-chloromethyl benzene in the side chain were obtained.

本文在环流反应器中进行了邻、对氯甲苯混合光氯化反应试验，分别考察了不同氯气流量、不同氯化温度和不同对/邻氯甲苯初始配比对对、邻氯甲苯侧链光氯化反应的影响，实测了反应液中各组分浓度随时间的变化关系，得出了对、邻氯甲苯的侧链光氯化反应规律和适宜的工艺条件。

Hospital waste water was treated with polysilicate aluminum as coagulant, and using chlorine dioxide to kill bacteria.

以聚硅酸铝为混凝剂，用化学法絮凝处理医院污水，并用二氧化氯杀菌。

The bactericidal activity of NEW for both of pathogens increased with increasing the available chlorine concentration and treatment time. A 100% inactivation of S. pullorum initial logarithm of population of pathogen 8.12 log10 (cfu/mL and E.

结果表明，中性电解水对2种病菌均具有较强的杀灭效果，其杀菌效果随着有效氯浓度和处理时间的增加而增强，但温度对中性电解水的杀菌效果影响不显著。

The S. pullorum on the surface of shell eggs was completely killed and E. coli O157:H7 logarithm of counts decreased to less than 1.0 log10 by NEW containing 12 mg/L available chlorine for 3 min without viable cells in the washing water after treatment.

当中性电解水清洗消毒被人工污染的鸡蛋表面时，有效氯质量浓度为12 mg/L、处理3 min可将鸡蛋表面的鸡白痢沙门氏菌全部杀灭，大肠杆菌O157：H7菌落数对数降低到1.0 log10 以下，且处理废液中没有残存菌，无二次污染问题。

The resin is prepared by swelling chlorine balls in a solvent such as nitrobenzene; adding catalyst to obtain polystyrene-divinylbenzene adsorptive resin; removing reaction mother solution; washing to remove residual solvent and catalyst; swelling; adding pyrane reagent to further react with chloromethyl residual on inner and outer surfaces of the resin to obtain the pyranyl modified adsorptive resin with the composite function.

该树脂的制备方法：将氯球溶胀于硝基苯等溶剂中，加入催化剂，得到聚苯乙烯-二乙烯苯吸附树脂；抽尽反应母液，洗去残留的溶剂和催化剂；溶胀，加入吡喃试剂与树脂内外表面残留氯甲基进一步反应，可制得吡喃基修饰复合功能吸附树脂。
