氯化氢

Several carbonates are synthesized from carbamates either with hydrochloride as coreactant or with zeolites as catalysts under low temperature and pressure, whereas high yield is achieved through either the formation of ammonium chloride as precipitate or the adsorption of ammonia in zeolites.

在较低温度和压力下，以氯化氢为共反应物或沸石分子筛为催化剂，由氨基甲酸酯与醇反应合成多种碳酸酯。

In the mixture gas of hydrogen chloride / nitrogen, the influence of pressure, concentration and cut-off ration are also researched on the permeability and separation factor.

在氯化氢和氮气混合体系，考察了压差、浓度和切割率对渗透系数和分离系数的影响。

Sythesis and application of chlorostyrene-DVB strongly acidic cation exchange resin ;2. For this study,a series of poly( p -amino styrenes) with various amounts of supported hydrogen chloride,and a series of strongly acidic cation exchange resin s with various exchange capacity were synthesized,and their catalytic property for ketalization of cyclohexanone and glycol were investigated.

通过测定固载了不同量的氯化氢的聚和不同交换量的强酸性阳离子交换树脂催化的环己酮与乙二醇的缩酮化反应缩酮的收率，研究了聚合物固体酸催化剂的疏水性对其催化缩酮化反应性能的影响；发现在一定范围内增加催化剂的疏水性，可提高缩酮化反应的收率。

Tze Wei of sulphur dioxide, hydrogen chloride, chlorine, hydrogen fluoride and other toxic gases resist sexual stronger.

紫薇对二氧化硫、氯化氢、氯气、氟化氢等有毒气体抗御性较强。

This paper introduced using K2SiF6 Volumetric Method to analyze the content of silicon in silicon tetrachloride recycled from sponge titanium production technology.

四氯化硅在空气中遇空气中水分极易分解为强腐蚀性的氯化氢气体和二氧化硅粒子，具有窒息性气味，给分析工作带来很大困难。

After dryness, silica powder is put into chlorinated furnace in fluid bed and reacts with dried hydrogen chloride gas in the environment of 340℃ to form crude trichlorosilane. The crude trichlorosilane , through hydroscrubber and pipe bundle condenser to extract silicon tetrachloride in distillation column produces trichlorosilane gas out of the d istillation column , which can be made into the finished product of trichlorosilane by condensation .

硅粉经干燥后加入氯化沸腾炉，与通入炉中的干燥氯化氢气体在340o C进行反应，生成的粗三氯氢硅经湿法除尘器、列管冷凝器去蒸馏塔分离匹氯化硅，由蒸馏塔出来的三氯氢硅气体经冷凝，制得三氯氢硅成品。

The mechanism of the second kind of FRs, FRs , can be described as"Accelerating the Elimination of HCl and Crosslinking by Ion Model". FRs can obviously promote the elimination of HCl, decrease the on-set temperature of decomposition of PVC, it can promote the crosslinking during decomposition, reduce the total output of aromatic compounds, increase the gel of condensed phase and char residue, the char residue is loosened.

第二类阻燃抑烟剂对PVC的阻燃抑烟机理可用&快速脱氯化氢离子交联模型&描述，其主要特点为：阻燃抑烟剂在热分解过程中，转化成为MCl〓，它一方面促进PVC释放HCl，另一方面，促使体系产生分子间交联，使裂解气相产物中芳烃化合物含量减少，凝聚相凝胶含量变大，残炭量提高，残炭物结构呈松散状态。
