Magnesium chloride is an inorganic compound with the formula Mg Cl 2. It forms hydrates MgCl2·nH2O, where n can range from 1 to 12. These salts are colorless or white solids that are highly soluble in water. These compounds and their solutions, both of which occur in nature, have a variety of practical uses.

2019年12月11日 · Andeselisk has pointed out that hydrared magnesium chloride decomposes to the basic salt Mg(OH)Cl M g (O H) C l unless the atmosphere is supplemented with hydrogen chloride gas. This basic salt decomposes upon further heating to give the oxide, a reaction that parallels the decomposition of magnesium hydroxide upon heating. From Wikipedia:

High-quality in situ synchrotron powder diffraction data have been used to investigate the decomposition products of bischofite in the temperature range 298 ≤ T ≤ 873 K. At least eight phases could be identified: MgCl 2 · n H 2 O (n = 1, 2, 4 and 6), MgOHCl· n H 2 O (0 ≤ n ≤ 1.0), MgCl 2 and MgO.

We find that doping MgCl2·nH2O with calcium considerably reduces HCl formation compared to its pure form, caused by a combination of the stronger Ca–Cl interaction than Mg–Cl and a less polar H2O molecule in a calcium environment than in a magnesium environment.

2021年1月3日 · Magnesium chloride is very water soluble and crystallizes from solution as the hexa-hydrate, MgCl2·6H2O. This salt cannot be dehydrated by simple heating because magnesium oxychlorides and magnesium oxides are formed with …

氯化镁又名卤片，化学式MgCl2。常见的是六水合氯化镁，又称水氯镁石，它的化学式为MgCl2·6H2O，式量203.30。晶体为无色易潮解的单斜晶体，有苦咸味。密度1.569g/cm3，熔点118℃(分解)，极易溶于水和乙醇。高于170℃时生成碱式氯化镁和氯化氢。

基于离子液体电化学窗口宽、热稳定性好等优良特性，进行水氯镁石热裂解产物（MgCl2·nH2O (n=2,4,6)）在 [Bmim]Cl (类)离子液体中富积和电化学行为的研究，是以水合氯化镁合成含镁离子液体用于镁的电沉积，可避开镁熔盐电解中无水氯化镁的来源限制，对实现绿色冶金和青海水氯镁石资源的综合开发利用具有重要的战略意义。 基于以上内容，本文具体工作内容如下： （1）使用微波合成仪，在微波功率550W、N-甲基咪唑和氯代正丁烷摩尔比为1:1.1、反应温度100℃、反 …

2018年1月2日 · A new efficient and solvent-free method for the synthesis of anhydrous MgCl2 from its hexahydrate is proposed. Fluidized dehydration of MgCl2·6H2O feedstock at 200 °C in a porous bed reactor yields MgCl2·nH2O (0 < n < 1), which has a similar diffraction pattern as activated MgCl2.

在干燥的HCl气流中加热MgCl2·6H2O,能得到无水MgCl2.下列说法不正确的是 A. MgCl2·nH2O(s)=MgCl2·(n-1)H2O(s)+H2O(g) ΔH>0 B. 。 MgCl2·2H2O(s)=Mg(OH)2(s)+2HCl(g),HCl气流可抑制反应进行 C. MgCl2·H2O(s)=Mg(OH)Cl(s)+HCl(g),升高温度,反应更易发生 D. 。
