三乙醇铝是什么,有什么用途
乙醇铝是一种化学物质,分子式是(C2H5O)3A
分子式:(C2H5O)3Al
分子质量:162.16
沸点:320℃
熔点:154-159℃
性质:吸湿性黏稠液体。沸点175到180℃(399.97Pa)。由无水乙醇与金属铝(实验室中常用铝汞齐)反应制得。是羰基化合物还原为醇的还原剂,酯化反应及聚合反应的催化剂。
实验采用三乙醇铝和三氯乙醛为原料合成三氯乙醇的工艺路线,首先考察了醇铝配比、乙酸乙酯对三乙醇铝活性的影响,然后考察了三氯乙醛与乙醇摩尔比、溶剂种类以及缩合反应时间对三氯乙醇收率的影响,获得了合成三氯乙醇的最佳工艺条件。
Experimental adopt three ethanol aluminum and trimethoxysilane trichloramine materials synthesis acetaldehyde for ethanol processing route, first inspected the alcohol aluminum ratio, ethyl acetate for three ethanol aluminum active effect, then examines the acetaldehyde and ethanol than trichloramine, solvent type and Moore condensation reaction time to the influence of the different ethanol yields obtained synthetic trimethoxysilane, the optimum process conditions of ethanol.
实验结果表明:制备三乙醇铝的合适配方为以乙酸乙酯为悬浮剂,醇铝比1:5.5较合适,无水乙醇用量取14g。
The experimental results show that the appropriate preparation of three ethanol aluminum with formula of ethyl alcohol for suspension agent, aluminum than 1:5. Five more appropriate, anhydrous alcohol consumption take 14g.
制备三氯乙醇的最佳工艺条件为三氯乙醛11.9g,溶剂乙酸乙酯60mL进行缩合反应,反应时间以35h较合适。
Preparation trimethoxysilane the optimum process conditions of ethanol for trimethoxysilane acetaldehyde 11.9 g, solvent acetic ester 60mL for condensation reaction, the response time to 35h more appropriate.
