Abstract
本发明公开无溶剂酰胺合成方法及其在高分子抗氧化稳定剂合成中应用,通过8个反应通式合成了不同结构酰胺连接硫醚高温长效抗氧化稳定剂,位阻酚硫醚杂化抗氧剂,位阻酚酰胺类抗氧剂等目标产物。这些酰胺稳定键连不同类型多功能基杂化结构抗氧剂与市场大多羧酸酯键连抗氧剂比较结构稳定,抗酸,抗碱,抗水解,抗环境降解能力强,协同抗氧化性能好,建立起新一代性能更加满足新材料发展需求的抗氧化稳定剂产品。这些新型高分子材料抗氧化稳定剂产品克服了市场同类酯键连抗氧化稳定剂的酯键在酸碱条件下分解,易水解等不稳定性能,同时大大的减少了现市场产品DSTDP/DLTDP使用加工中产生的气味和降解材料中释放VOCs的问题,为新型高分子材料发展提供了有力支持和更多选择的抗氧化稳定剂。
Description
技术领域
本发明属于高分子抗氧化稳定剂合成制备领域,特别涉及一种无溶剂酰胺合成方法及在高分子抗氧化稳定剂合成中应用。
背景技术
现阶段工业上广泛的羧酰胺合成方式是将羧酸酰氯化,然后再与有机胺反应,两步化学反应合成出羧酰胺产品。常用的酰氯化试剂有SOCl2和C2O2Cl2,通过DMF或DMAP的催化,加快羧酰氯的转化,反应中过量的SOCl2或C2O2Cl2会不可避免的盐酸气产生,和不愉快的酰氯气味;下一步羧酰氯在必要过量或至少定量的缚酸碱存在下才能有效的与有机胺耦合反应产生羧酰胺产物。在这两步反应中,过量试剂,反应中释放出来的气味,副产物等都表明这类反应虽然有效,原料成本低,但是有明显的不氯色环保,操作繁琐,三废处理麻烦等缺点。此外其它羧酸直接通过缩合试剂与有机胺反应也是制备羧酰胺的又一类普遍方法,常用试剂有DCC/HOBt,EDCI,BOP,PyBOP,BOP-Cl,FDP,FDPP,DEPBT,PyBr,TBTU,HBPyU,HATU,HAPyU,HDTU,HAPyTU等,一般来讲缩合试剂较贵,副产物一定会同时产生,给最终产物分离纯化带来繁琐。引进活性基团活化羧基,然后有机胺与其发生取代反应制备羧酰胺是另一种羧酰胺的常用制备方法,常见的活化酯有硝基苯酯,2,4,6-三氯苯酯,五氯苯酯,五氟苯酯(PfOH),N-羟基琥珀酰亚胺(HOSu)酯和N-羟基苯并三唑酯(HOBt)等。一般的操作步骤是先制备并分离得到活化酯,再与胺反应得到酰胺,两步反应,要求有效后续副产物分离纯化步骤,成本高。
发明内容
本发明在于提供一种通过无溶剂羧酸盐催化下甲酯和有机胺进行缩合反应而成的无溶剂酰胺合成方法,其具有转化率高,操作方便的特点,尤其适于绿色环保生产,是目前为止最经济、最方便、最环保的制备羧酰胺的生产转化过程。

一元胺和二元胺与甲酯的反应方程式:
n:自然数;
R:H,Me,Et,n-Pr,i-Pr,n-Bu,i-Bu,t-Bu,长链烷基
RCO2Na:HCO2Na,CH3CO2Na等。该实施例加热控制升温是一个重要的因素,反应在长时间高温情况下会变黄,产品质量下降,对应的反应条件请见下表:Beta-硫醚甲酯与一元和二元有机胺在羧酸盐催化下缩合反应
注释:n.a.意思是没有应用到此(not applicable)
合成实例丙烯酸甲酯为原料:
第一步:丙烯酸甲酯与硫醇在无溶剂羧酸盐催化条件下经过Michael 1,4-加成反应得到beta-硫醚甲酯,反应需要控制温度,搅拌在1-24小时左右为好。第二步:有机胺与硫醚甲酯中间体反应,有机胺可以是第一胺,第二胺;有机胺可以是一胺,二胺,三胺等;有机胺在羧酸盐催化下,加热无溶剂反应条件下完成,反应完成时间与催化剂量,反应温度有关,反应在最佳温度范围,最佳反应时间内转化率可达85-99%,如果甲酯过量或有机胺过量反应可定量完成。有机多元胺(例如,丁二胺,己二胺,三胺等)与硫醚甲酯反应,硫醚甲酯最好过量,相反如果选择多元胺过量,给反应完全彻底带来麻烦,多元胺的部分反应产物量增大,给多元胺完全反应产物分离带来困难。
