摘要

(CN106632111) 本​发明​公开​了​种​通过​无​溶剂​缩合​合成​2、2′－亚​甲基－双[4－特​辛​基－6－(2H‑苯​并​三​唑​基－2)]苯酚(UV‑360)的​方法。其​过程​是：先以​二​正​丙基​胺​和​甲醛​或​多​聚​甲醛​为​原料，在​温度​约​120℃的​条件下​缩合​脱水​合成​二(正​丙基​氨基)甲烷，再​和​2‑(2′‑羟基‑5′‑特​辛​基​苯基)苯​并​三​唑​在​无​溶剂​和​氢氧化钠​的​催化作用​下于​约​160℃缩合​合成​UV‑360。由于​该​方法​不使​用​高沸点​溶剂，克服​了​现有​方法​存在​的​问题，即​二​正​丙基​氨​容易​回收​及​循环使用，且​产品​质量​高。
