本文开发了氯化氢-氯化锌使松香树脂酸的异构-二聚同时进行的新工艺,探讨了对工艺影响的因素,优选出工艺最佳条件,证实该工艺具有良好的可控性和稳定性,140标号的聚合松香其二聚体含量达60％或更高。氯化氢不仅有异构能力和活化反应体系,降低反应的活化能,并且在多方面有良好的促进作用,如:提高了产品的二聚体含量,减少了脱酸作用,稳定了工艺条件和产率。 In this paper, a new process of simultaneous and heterogeneous dimerization of rosin resin acid with hydrogen chloride and zinc chloride was developed. The factors affecting the process were discussed, and the optimum process conditions were optimized. The process was proved to be well controllable and stable Polymeric, rosin, 140, has a dimer content of 60% or higher. Hydrogen chloride not only has the ability of isomerization and activation of the reaction system, reducing the activation energy of the reaction, and in many aspects have a good role in promoting, such as: increased dimer content of the product, reducing the deacidification, stabilizing the process conditions and production rate.
