Abstract
本发明提供一种水溶性抗氧化剂及其制备方法,该水溶性抗氧化剂为具有式(1)的化合物,其中,R1与R2可互为相同或互不相同的含C1~C18的直链或支链烷基或C5~C12环烷基;R3与R4可互为相同或互不相同的含C1~C6的直链或支链烷基或氢;M为IA金属离子或氢原子;a为2至6的整数;b为0、1、2、3或4;m为1或2;n为2至500的整数;p为1、2或3;q为1、2或3;及r为0或1,且p、q与r须满足p+q+2r=4的式子。该水溶性抗氧化剂为含3‑(3,5‑二叔丁基‑4‑羟苯基)丙酸甲酯基团/聚亚烷基二醇架桥/羧酸基团的亲水性抗氧化剂,其具有低挥发性与高水溶性,同时也具有界面活性剂(乳化剂)的特性,在工业上可帮助其它油溶性抗氧化剂应用于水相系统中。
Description
技术领域
本发明有关一种制备亲水性抗氧化剂的方法,尤其是有关一种制备含3,5-甲酯基团/聚亚烷基二醇架桥/羧酸基团亲水性抗氧化剂的方法。
背景技术
塑料高分子链在紫外光、热的作用下容易发生断链而生成活性自由基,活性自由基再与氧反应形成过氧化自由基后,再与剩余的分子链反应,形成氧化产物和新的活性自由基,活性自由基则持续引发自由基链锁反应,而使塑料发生老化现象。
3-(3,5-二叔丁基-4-羟苯基)丙酸甲酯(简称3,5-甲酯)类受阻酚类分子是塑料中常用的一级抗氧化剂,其具有高分子量、低挥发性、高抗氧化特性与低毒性的优点,但此类抗氧化剂受限于水溶性差,故无法单独于水相系统中使用。
常见的水溶性抗氧化剂多为天然物,例如维他命C、维他命B、茶多酚,多应用于生物系统的医疗研究,此类天然水溶性抗氧化剂未含有3,5-甲酯基团。
3,5-甲酸类受阻酚类小分子如3,5-二叔丁基-4-羟基苯甲酸、3,5-二叔丁基-4-羟基苯乙酸与3,5-二叔丁基-4-羟基苯丙酸虽兼具水溶性与抗氧化性,但属于低分子量小分子,于高温受热下易迁移离开(挥发散逸)基材表面,且本身也会因老化分解而降低抗氧化能力,造成此类小分子抗氧化剂对基材的抗老化作用无法长久有效。
聚乙二醇(PEG)具有无毒性、无刺激性与良好的水溶性,属于非离子型界面活性剂而与许多有机物具良好的相溶性,其在化妆品、制药、化纤、橡胶、塑料、造纸、油漆、电镀、农药、金属加工、生物工程及食品加工等行业中被广泛的应用。
美国专利案US 4,032,562报导将3,5-甲酯与PEG进行单边酯交换反应得到3,5-甲酯/PEG单边酯化产物,如23-羟基-3,6,9,12,15,18,21-七氧杂二十三烷基3-(3,5-二叔丁基-4-羟基苯基)丙酸甲酯,此结构引入了亲水性聚合物PEG,虽然使其分子量上升而改善挥发性过低的问题,但水溶性仍属于微溶(5.8g/L@pH=1~10、文献理论计算),类似的合成反应可参考US3285855、US3441575、US5696281、DE2231671与CN100430366C,其产物也是属于油溶性。
聚乙二醇与3,5-甲酯进行双边酯交换反应得到3,5-甲酯/PEG双边酯化产物,如三甘醇双[(3-叔丁基-4-羟基-5-甲基苯基)丙酸酯]、二甘醇双[3-(3,5-二叔丁基-4-羟基苯基)丙酸酯]、三甘醇双[3-(3,5-二叔丁基-4-羟基苯基)丙酸酯]、四甘醇双[3-(3,5-二叔丁基-4-羟基苯基)丙酸酯]、九甘醇双[3-(3,5-二叔丁基-4-羟基苯基)丙酸酯],此类结构虽含两个3,5甲酯基团,使其相较单边产物具较佳的抗氧化性与更低的挥发性,但水溶性却变得更差,无法单独应用在水相系统。
德文期刊「应用巨分子化学与物理(Die Angewandte Makromolekulare Chemie)」260期(1998年)第77–81页揭示将3,5-二叔丁基-4-羟基苯丙酸与11-[(2R,3S)-3-戊基-2-环氧乙烷基]-(9Z)-9-十一碳烯酸进行环氧基开环反应而得到含有羧酸基的3,5-甲酯单边分子(9Z)-13-(3-(3,5-二叔丁基-4-羟基苯基)丙酰氧基)-12-羟基十八碳-9-烯酸,此抗氧化剂虽含有一个亲水性羧酸基,但其水溶性仍属于微溶。
综合上述论点,同时兼具低挥发性、水溶性佳且含3,5-甲酯基团的抗氧化剂分子尚未被报导。
发明内容
本发明的一目的在于提供一种水溶性抗氧化剂及其制备方法,以解决现有技术的抗氧化剂水溶性仍属于微溶的缺陷。
为实现上述目的,本发明提供一种水溶性抗氧化剂,该水溶性抗氧化剂为具有式(1)的化合物,
其中,

化合物(2)为3,5-甲酯类结构,其中X可为卤素例如氯或溴、羟基或烷氧基,例如碳数小于4的烷氧基,诸如甲氧烷基或乙氧烷基;
R1与R2可互为相同或互不相同含C1~C18的直链或支链烷基,支链烷基含有二级与三级碳,如甲基、乙基、丙基、异丙基、正-丁基、仲-丁基、异丁基、叔-丁基、2-乙基丁基、正-戊基、异戊基、1-甲基戊基、1,3-二甲基丁基、正-己基、1-甲基己基、正-庚基、异庚基、1,1,3,3-四甲基丁基、1-甲基庚基、3-甲基庚基、正-辛基、2-乙基己基、1,1,3-三甲基己基、1,1,3,3-四甲基庚基、壬基、癸基、十一烷基、1-甲基十一烷基、十二烷基、1,1,3,3,5,5-六甲基己基、十三烷基、十四烷基、十五烷基、十六烷基、十七烷基或十八烷基,较佳为甲基与叔丁基;

酯交换是一种常见的平衡反应,为了使平衡的方向偏向于产物,在反应进行过程中可以持续地将副产物从反应系统移除,比较便利的方式是酯交换反应进行中蒸除低沸点的低碳数醇类副产物如甲醇;另外也可增加反应物的浓度达平衡偏向产物之目的,此处选择将化合物(3)配比增量除了使平衡偏向于产物外还可达使单边酯交换的中间体(4)成为主要产物之目的。

当以单烯三元酸(5-2)或单烯四元酸(5-3)作为反应物时,可藉由中间体(4)与单烯三元酸(5-2)或单烯四元酸(5-3)间的配比调控,而得到以3,5-甲酯/聚亚烷基二醇基团为主要组成或以羧酸基团为主要组成之中间体(6)混合物。酯化程度越高,则化合物(5)接上3,5-甲酯/聚亚烷基二醇基团的程度也会越高,分子量增加的程度也会越高;酯化程度越低,则化合物(5)未反应残留的羧酸基团会越多,分子量增加的程度也会越低,所以主要是藉由GPC来定量中间体(6)混合物中的主要组成为何。
以3,5-甲酯/聚亚烷基二醇基团为主要组成的中间体(6)混合物其抗氧化性能较佳,但水溶性较差;以羧酸基团为主要组成的中间体(6)混合物其水溶性较佳,但抗氧化性能较差。
最后一步为中间体(6)于碱性条件下进行皂化反应而得到化合物(1)的水溶液,适用的碱液有氢氧化钠或氢氧化钾水溶液。
