二甲基氨乙基甲基丙烯酸酯合成的研究报告

本研究选用四种价格较低,使用方便且无毒的催化剂,通过酯交换反应,成功地合成出DMAM产品。研究了几种催化剂的用量、合成条件等对产品得率、反应速度及釜残量的影响,并通过物理常数的测定和气相色谱分析,对产品进行了定性和定量分析。结果表明产品纯度达99％以上,已达到日本同类产品纯度指标。同时具有设备简单,操作方便,价格低廉等优点。

RESEARCH REPORT OF COMPOSITION OF N.N-DIMETHYL AMINO ETHYLMETHACRY

N.N-Dimethyl amino ethylmethacry (DMAM) is a new chemical medium products of positive ion. It may compose many high molecular weight compound of aqueous solution, which can be used in pulp and paper production, printing and dyeing, spinning and weaving, mental process, additive of lubricate oil, treating waste water and so on. In the research, we have been chosen four kinds of catalyst. They are low in cost, convenient in use and nonpoisonous. DMAM in composed by reaction of ester exchange. We have studied the effect on quality of catalyst, the condition of composition, reaction rate and quantity of the waste residue. We have determined physics constant and have been in the process of gas chromatography analyssis of determining the character and fixed quantity. It has been proved that purity of the products have reached 99%, which is up to the standard of the same products made in Japan, whose equipment is simple and easy in operation and low in price, too.
