摘要
旨在提升我国二聚酸工业化水平和产品竞争力,从合成和应用两个方面对近年来二聚酸的研究进展进行了综述.二聚酸以C18不饱和脂肪酸为原料,通过Diels-Alder反应或碳正离子反应机制经催化聚合或热聚合制备得到,通过分子蒸馏提纯后二聚酸含量可高达98％以上;二聚酸在合成聚酰胺树脂、聚酯类化合物、氢化二聚酸以及生产润滑剂和腐蚀抑制剂等方面均有应用.建议进一步对二聚酸合成机制、合成工艺及下游产品的应用进行深入研究.
Abstract
In order to enhance the industrialization level and product competitiveness of dimer acid,the research progress on dimer acid from two aspects of the synthesis and application in recent years were reviewed.Dimer acid can be obtained by catalytic dimerization or thermal dimerization of C18 unsaturated fatty acids through Diels-Alder reaction or carbocation reaction mechanism,and the content of dimer acid can reach more than 98％by molecular distillation.Dimer acid has been used in the synthesis of polyamide resin,polyester compounds,hydrogenated dimer acid and production of lubricants and corrosion inhibitors.Further studies of the synthesis mechanism,synthesis technology and downstream product application of dimer acid should be performed.
