Due to the ability of the bivalent magnesium cation to form stable chelate complexes with carbonyl compounds,magnesium methylate for example is used as a selective carbonyl condensing agent. Three synthesis routes was proposed based on literatures and comprehensive comparison with other ways. First,Magnesium methylate is prepared by reacting magnesium metal with dry methanol.The magnesium salts of"higher"primary alcohols,i.e.alcohols with ≥ 2 carbon atoms,do not react directly with pure alcohols under normal conditions.In fact catalysts are required to set the reaction in motion and the preparation is performed under pressure at the higher temperatures.

一、直接合成法：本文将镁与无水甲醇直接反应制得甲醇镁；"更高级"的醇（比如C≥ 2的醇）在无催化剂的条件下无法直接和镁进行反应，本文以CCl4为催化剂将无水乙醇与镁直接反应制得乙醇镁，但是以原甲酸三乙酯为催化剂无水乙醇与镁无法反应；不论是以CCl4为催化剂还是以原甲酸三乙酯为催化剂，丙醇均无法与镁直接反应。

As the results, both the friction and wear are much lower in n-monohydric alcohols than in water; in ethanol, the friction and wear increase rapidly when a small amount of water was blended into the lubricant; the friction and wear decrease slightly with increasing the chain length in n-alcohols; in polyhydric alcohols, the increase of the hydroxyl number greatly reduces the friction and wear.

研究结果表明，陶瓷在醇中的摩擦和磨损均比水中低；在乙醇中加入少量水可明显增大其摩擦和磨损；随着一元醇分子链长的增加，其摩擦磨损略有降低；多元醇中羟基数目越多，其摩擦磨损越低。

Differential Scanning Calorimetry and Small Angle X-ray Diffractometry were used to characterize the phase transitions in lamellar liquid crystal systems containing water, alkyl polysorbates, sorbitan esters, stearyl alcohol and oil. The order-disorder transition temperatures of the gelled O/W and W/O globular onion lamellar phases L(subscript O1) and L(subscript O2) and planar gelled lamellar phase L(subscript β) were measured as a function of system compositions.

It is prepared from titanium tetrachloride carried on an alcohol carrier that Mg and Li chlorides with molar ratio of 1:(2-20) are dissolved in alcohol, and by: co-dissolving Mg chloride and Li chloride in a low carbon alcohol and stirring at high speed in an inert medium to form micro-particles; reacting the said alcohol with titanium tetrachloride twice, adding organic acid polyester at first time, washing out uncarried titanium tetrachloride, and drying to obtain powdery pruduct.

它是由四氯化钛负载于将氯化镁和氯化锂共溶于醇形成的醇合物载体上组成，其中氯化锂与氯化镁的摩尔比为1∶2～1∶20。这种主催化剂组分的制备有两个步骤：(1)无水氯化镁和氯化锂共溶于低碳醇中形成醇合物，并在惰性介质中高速搅拌形成醇合物微粒；(2)醇合物与四氯化钛进行两次反应，其中第一次反应时加入有机酸多元酯。反应结束后用惰性溶剂洗去未负载的四氯化钛，干燥后得到呈粉末状的主催化剂组分。

Their technology and process is basically similar to that used ethylene, the raw material for the oxygen in the silver catalyst, caused by methane or nitrogen stabilizer, the existence of inhibitors of chloride, ethylene oxide directly generate ethylene oxide and ethylene B N and further to certain substances in water than in the tubular reactor for generating hydration ethylene glycol, ethylene glycol solution through evaporation to mention thick, dehydration, fractionation be ethylene glycol and other by-products.

它们的工艺技术和工艺流程基本上相似，即采用乙烯、氧气为原料，在银催化剂、甲烷或氮气致稳剂、氯化物抑制剂存在下，乙烯直接氧化生成环氧乙烷，环氧乙烷进一步与水以一定物质的量比在管式反应器内进行水合反应生成乙二醇，乙二醇溶液经蒸发提浓、脱水、分馏得到乙二醇及其他副产品。
