水杨醛乙二醇缩醛合成的研究
摘要: 以***化铵为催化剂,水杨醛(salicylaldehyde)和乙二醇为原料,甲苯为溶剂反应合成水杨醛乙二醇缩醛。本文考察了影响水杨醛缩乙二醇醛的合成工艺影响因素。利用单因素实验方法,分别研究了反应时间、溶剂用量、乙二醇用量、摩尔比等对水杨醛缩乙二醇醛的影响。以水杨醛乙二醇缩醛的收率为指标,结果表明较好的反应条件是:反应时间为几小时、溶剂用量为多少ml、乙二醇用量为多少ml、摩尔比为多少ml。借此,本文为水杨醛的进一步发展与开发利用提供了参考。(要求150字左右)

毕业论文外文摘要
The Study of Salicylaldehyde and Ethylene Glycol Acetyl’s Synthesis
Abstract: The salicylaldehyde ethylene glycol acetal was synthesized by the reaction of salicylaldehyde and ethylene glycol, the catalytic agent was ammonia chloride, and the solvent was toluene. The affected factors on synthesis of salicylaldehyde ethylene glycol acetal were discussed. The single factor method was applied in the experiment, and the reaction time, the volume of solvent and ethylene glycol, mole ratio were also researched. With the aim of yields of salicylaldehyde ethylene glycol acetal, the result indicated that the optimum reaction condition as follows: the reaction time was 多少hours, the volume of solvent was 多少ml and the amount of ethylene glycol was 多少ml, the mole ratio was 几比几,and the amount of catalytic agent was 多少. From this, it provided the further step and exploit consult of salicylaldehyde.
Keywords: salicylaldehyde;ethylene glycol; acetyl;methylbenzene
