二聚酸作为一种重要的化工原料,被广泛用作印刷电路板材料,油墨制造,火箭发动机材料及燃料油,润滑油,压延油,切削油中作改性添加剂,其生产及加工工艺一直备受关注。文章重点介绍了二聚酸聚合生产过程工艺实践,对影响二聚酸品质的因素:脂肪酸原料、水份、碱性碳酸锂、时间长短、温度、白土及氧气残留量的影响进行分析,指出生产工艺中常见问题,值得在油脂厂中推广使用。 Dimer acid as an important chemical raw materials, is widely used as a printed circuit board material, ink manufacturing, rocket engine materials and fuel oil, lubricating oil, rolling oil, cutting oil as a modified additive, its production and processing has been Concerned. The paper mainly introduced the process of dimeric acid polymerization process and analyzed the factors affecting the quality of dimer acid: the influence of fatty acid raw material, water, alkaline lithium carbonate, time, temperature, clay and oxygen residue, Common problems in the process, it is worth to promote the use of oil plant.
