摘　　要：抗氧剂1098属于高相对分子质量分子内复合型受阻胺受阻酚抗氧剂,一般以3,5-甲酯与己二胺为原料,在碱性催化剂作用下通过氨解反应合成,有低温和高温2种合成工艺,无论是低温工艺还是高温工艺,其核心是反应的催化剂,由于锡的毒性,有机锡催化剂导致的锡残留严重限制了该抗氧剂的应用,因此抗氧剂1098合成工艺改进的核心是以新型碱催化剂取代有机锡催化剂,同时提高溶剂的回收率,降低生产成本。该抗氧剂在国内已实现商业化生产并得到广泛应用。可提高尼龙的抗黄变性、耐热、耐湿热稳定性以及力学性能保持性;可提高PVA及PVB的热稳定性;可提高PASS的熔体稳定性和流动性;可改善聚酯粉末的耐黄变性能;可提高环氧黏合剂的耐热及耐湿热老化性能;可改善ABS树脂的耐辐照性能。Antioxidant 1098 belongs to the high relative molecular weight intramolecular complex hindered amine hindered phenol antioxidant.Generally,3,5-methyl ester and hexamethylenediamine are used as raw ma-terials and synthesized by amolysis reaction under the action of alkaline catalyst.There are two synthesis pro-cesses,i.e.,low temperature and high temperature,and the core of both the two processes is the catalyst for reaction.Due to the toxicity of tin,the tin residue caused by organotin catalyst severely limits the application of the antioxidant,so the core of the improvement of the synthesis process of antioxidant 1098 is to replace the organotin catalyst with a new base catalyst,and at the same time improve the solvent recovery rate and reduce the production cost.This antioxidant has been commercially produced and widely used in China.It can improve the yellowing resistance,heat resistance,moisture and heat resistance and mechanical property reten-tion of nylon,improve the thermal stability of PVA and PVB,improve the melt stability and fluidity of PASS,improve the yellowing resistance of polyester powder,improve the heat resistance and moisture heat aging re-sistance of epoxy adhesive,and improve the radiation resistance of ABS resin.
