摘　　要：以N-张链烷基-β-氨基丙酸乙酯和马来酸双酯为原料，通过调节两者配比，合成了一系列结构由α-长链烷基和β-氨基丙酸钠及α-氨基乙酸钠组成的两性表面活性剂产品（简称MAPA）。对α-长链烷基-β-氨基丙酸乙酯合成的反应温度和反应时间进行了选择，确定为85℃下反应2．5h。对合成的MAPA系列产品的物理性能如乳化性、润湿性、等电点和表面张力等进行了测定。用MAPA系列产品作为皮革染料NG-3的染色增艳荆，对其助染性能进行了研究。加入MAPA-1后，染料NG-3紫外光谱的K-谱带从192nm红移到205nm，最大吸收强度从0．950提高到2．222；当MAPA-1的浓度为4g／L，原料质量配比（十二胺：丙烯酸乙酯：马来酸双酯）为1：1．2：0．6时，其助染性能最好；皮革染色试验，加入坯革质量1％的MAPA-1染色增艳剂，成革的透染率从75．36％提高到94．57％。上染率从85．2％提高至97．4％，染色革的耐干、湿擦牢度分别由4—5级和4级提高到5级。A series of new type of amphoteric surfactants （ MAPA）with the main structure of N - alkyl , β- alanine and α- aminoacetic acid were synthesized by N - alkyl - β- aminopropionic ethyl ester and maleic diester through modulate their mol α-tion . It discussed the synthesis conditions of N - alkyl - β- aminopropionic ethyl ester and identified as 85℃ and 2. 5h. The physical properties of MAPA series products were detected such as emulsibility , wettability, isoeleetric point and surface tension. The dyeing assistant properties of MAPA were studied by using it on leather dye NG - 3 . The K - band of the dye＇ s ultraviolet spectnun red move from 192nm to 205nm and the absorption intensity increased from 0. 950 to 2. 222 when being added in MAPA - 1. The dyeing assistant properties is the best when the MAPA＇ s concentration is 4g/L and the raw material mole ration is 1： 1.2 ： 0. 6（ twelve amine： ethyl acrylate： maleic diester）. When being used in leather dyeing ,the deepdye ratio increased from 75.36% to 94. 57% ,the dyeuptake improved from 85. 2% to 97. 4% and the dry and wet rubbing resistant changed respectively from level 4 - 5 and 4 to level 5.
