Abstract
本发明涉及一种多胺的合成方法及多胺。该方法以下步骤:步骤1:将式(I)的不饱和酯a):R1(R2)C=C(R4)‑COOR3(I);与b)X‑(NH2)n(II)在0‑100℃进行迈克尔加成反应获得含有一个或更多个仲氨的树脂;其中a)与b)不饱和双键与伯氨基的摩尔比为0.1‑1.05;步骤2:将步骤1中获得的树脂与每分子含有f个羟基基团且数均分子量从62至20000的的多元醇进行酯交换反应。本发明还涉及利用该方法获得的多胺。根据本申请的方法拓宽了原材料使用种类,可以通过此反应增加低元胺的官能度,制备成有实用性的多胺。
Description
技术领域
本发明涉及聚合物合成领域,更具体而言,涉及一种多胺的合成方法及利用该方法制备的多胺。
背景技术
在已知的合成技术中,英国专利GB1017001描述了不饱和聚酯与伯胺或仲胺与α,β-不饱和聚酯酯基α,β-位的双键加成获得的加成产物。α,β-不饱和聚酯通过α,β-不饱和单羧酸和/或多羧酸或其衍生物与多羟基醇酯化或酯交换制备。所述产物具有残留的酸,残留的羧酸在后续与伯氨的加成反应中极易产生铵盐,会造成聚氨酯与天门冬氨酸酯树脂的反应速度过快。
高度支化的聚天冬氨酸酯也是已知的(例如,参见US 5,561,214)。这些高度支化的聚天冬氨酸酯通过羟基天冬氨酸酯自身聚合或至少一部分羟基天冬氨酸酯的羟基和酯基发生酯交换制备,但是这只适用与含有羟基的伯氨,对于不含羟基的伯氨这无法进行此种反应。
在CN1616513A中描述了使用多官能度的马来酸酯与伯氨加成制备聚天门冬氨酸酯树脂的方法,其中多官能度马来酸酯通过马来酸二甲酯、马来酸二乙酯、马来酸二丙酯、马来酸二丁酯等一些单不饱和双键的马来酸二酯与多元醇经过碱性催化剂作用下,酯交换生成多官能度的马来酸酯后,再与伯氨进行加成反应。此种通过酯交换法制备多不饱和度马来酸酯的方法,在脱除酯交换过程中产生的一元醇过程中,极易将反应中的原材料单不饱和双键的马来酸酯带出,造成原材料比例失调,从而影响多不饱和度马来酸酯的官能度比设计值偏高。
发明内容
针对现有技术存在的不足,本发明的目的是提供一种多胺的合成方法,该方法包括以下步骤:
步骤1:将下式(I)的不饱和酯a):
R1(R2)C=C(R4)-COOR3 (I)

具体实施方式
目前已经存在不少多胺合成方法(例如CN1616513A)。然而,在对现有技术进行研究的过程中,本申请人发现其存在不少的问题。例如,在脱除酯交换过程中产生的一元醇过程中,极易将反应中的原材料单不饱和双键的马来酸酯带出,造成原材料比例失调,从而影响多不饱和度马来酸酯的官能度比设计值偏高。
对此,为了减小副反应对产品的色泽、不饱和度的影响,需要尽可能缩短酯交换反应的时间,然而这也造成了反应中多元醇原材料中的羟基残留,而羟基会使天门冬氨酸酯树脂与聚氨酯反应速度加快,这并非所希望的结果。
进一步地,为了尽量提高反应的转化率,需要将温度升高至150℃,导致产物的色泽加深。在碱性催化剂存在下,多元醇不仅与马来酸酯进行酯交换反应,并且存在多元醇羟基与不饱和双键的加成反应,在较高的温度下不饱和双键还会有一定程度的聚合,而聚合后的多不饱和马来酸酯沸点极高或是无法汽化。对于这些原材料、副产物、中间产物与产品,通常所使用的分离方法并无法对产品进行有效的分离精制,这些杂质通常会对后续与聚氨酯的使用、材料的最终性能有很大的影响。此种改性方法也局限于高沸点不饱和酸酯,对于低沸点的丙烯酸酯类的改性则由于沸点过低与丙烯酸酯在高温下易于挥发、聚合而无法进行改性。
由此可见,在现有合成多胺(尤其是天门冬氨酸酯树脂)的现有方法中,仍存在诸多问题。因此,本申请人的发明人对此进行了大量研究,并基于这些研究对现有方法进行了改进,从而完成本发明。
具体而言,本发明人提供一种改进的多胺合成方法。该方法可以包括以下步骤:步骤1:将下式(I)的不饱和酯a):R1(R2)C=C(R4)-COOR3 (I),其中R1可以为酯基、酰胺基、烃基及氢原子,R2、R4可以相同或不同,并表示在100℃下呈化学惰性的氢或有机基团;与b)X-(NH2)n (II),其中X为表示在150℃或更低的温度下稳定的有机基团,n为1-3范围内的整数;在0-100℃进行迈克尔加成反应获得含有一个或更多个仲氨的树脂;其中a)与b)不饱和双键与伯氨基的摩尔比为0.1-1.2;步骤2:将步骤1中获得的树脂与每分子含有f个羟基基团且数均分子量从62至20000的的多元醇进行酯交换反应;其中f为2-6的整数,所述多元醇的羟基与酯键的比例为0.1-1。
