The authors reported the synthesis of C102 macroporous cation exchange resin from ST-DVB copolymer via chlorination and sulfonation, with NB-1 weak polar solvent as pore formation agent. 以NB-1型弱极性溶剂为致孔剂合成的ST-DVB共聚体为骨架,经氯化、磺化制得C102大孔阳离子交换树脂。
In the reaction of chlorination, carbon tetrachloride was used as agent, and chlorine gas as chlorinating agent. 在氯化反应中,以四氯化碳为溶剂,氯气为氯化剂。
A clean process of recovering chlorination mother liquor generated in ADC foaming agent production ADC发泡剂生产中氯化母液的清洁回收工艺
N-acylation takes place from ester as acylating agent and amine, which avoids the reaction of esterolysis and chlorination. Compared to the former method using irritant acyl chloride as acylating agent, this new process shortens the reaction steps and avoids pollution. N-酰化反应,直接用酯作为酰化试剂与胺反应,代替了有强烈刺激性的酰氯,避免了酯的水解、氯化反应,既减少了反应步骤,又有利于清洁生产;
Then, 2-methyl-2-hydroxy-1-phenyl-1-pentanone was prepared by chlorination and hydrolysis with 2-methyl-1-phenyl-1-pentanone in the presence of NaOH and CCl4 as chlorinating agent and tetrabutyl ammonium bromide as the phase transfer catalyst. 最后在氢氧化钠水溶液中,以四氯化碳为氯化试剂,四丁基溴化铵作相转移催化剂,2-甲基-1-苯基-1-戊酮直接氯代和水解制得2-甲基-2-羟基-1-苯基-1-戊酮。
In chlorination treatment, a dosage of 3% chlorine releasing agent should be used at a temperature of 20 ℃ and pH4 in 60 minutes. 氯化整理工艺:释氯剂3%,温度20℃,pH为4,时间60min。
On the basis of testing results of gold leaching from lateritic gold ores in Hubei by cyanide process and chlorination process, this paper discusses the advantages and disadvantages of two leaching methods above as well as rational selection of leaching agent for lateritic gold ore. 根据氰化法和水氯化法对湖北省红土型金矿石浸金试验结果,论证红土型金矿石浸出剂的合理选择,兼评二者长短。
Lower chlorine content in RRG, less loss of chlorine in catalyst and less use of chlorination agent. 再生循环气体的氯含量低,且催化剂上的氯流失少,所需氯化剂用量少,设备材质要求低;
A safer and environment-friendly chlorination agent was used to instead of SOCl_2 and phosgene. 采用一种更安全、更环保的氯化试剂&固体光气代替氯化亚砜和光气进行氯化反应,选择了合适的引发剂。
