【摘要】 以仲辛基苯酚、甲醛、氨水等为主要原料,氢氧化钠为催化剂,合成了新型有机锌润滑油添加剂的中间体———芳胺基中间体.确定了合成的最佳工艺条件,即:反应温度为90℃;仲辛基苯酚、甲醛、氨水物质的量比为2.0∶2.0∶1.0;反应时间为4h;催化剂的质量分数为1.0%;阻聚剂的质量分数为0.05%.在此条件下,芳胺基中间体收率可达85%以上.经红外光谱分析及对相对分子质量、氮的质量分数的测定,芳胺基中间体的相对分子质量约为470,氮的质量分数为2.90%～3.10%,与理论值接近.更多还原

【Abstract】 An intermediate product in the synthesis of a new type of organic zinc lubricating oil additive—alkyl arylamino dithiophosphate zinc—was synthesized from octyl phenol, ammonia and formaldehyde, taking sodium hydroxide as catalyst. The influencing factors on the synthesis were studied, and the proper technological conditions were given as follows. The reaction temperature is 90 ℃;the mass ratio of octyl phenol, formaldehyde and ammonia is 2.0∶2.0∶1.0;reaction time is 4 hours;the content of catalyst is 1.0%;the content of inhibitor is 0.05%. The molecular weight of the intermediate product is about 470, and the content of nitrogen is in the range of 2.90%～3.10%. The yield of the product is over 85%. The IR spectra analysis confirmed the correction of the synthesis route.更多还原
