Preparation method of isotridecanol isononanoate

The invention relates to a preparation method of isotridecanol isononanoate. The isotridecanol isononanoic acid ester is synthesized by esterification reaction of isotridecanol and isononanoic acid in the presence of a stannous chloride catalyst, and the whole production process comprises the procedures of esterification, dealcoholization, decoloration and the like to prepare the isotridecanol isononanoic acid ester. The catalyst stannous chloride is used in the preparation method, the esterification period can be shortened, the catalyst can be recycled, the conversion rate is improved, the production cost is reduced, meanwhile, post-treatment such as neutralization alkali washing and water washing is not needed in the reaction process, sewage discharge and sewage treatment cost are avoided, water resources are saved, and the environment is not polluted. 本发明涉及一种异十三醇异壬酸脂的制备方法。本发明采用异构十三醇与异壬酸在氯化亚锡催化剂下经过酯化反应合成，整个生产过程为酯化、脱醇、脱色等工序，制得异十三醇异壬酸脂；制备方法中用到了催化剂氯化亚锡，可以缩短酯化周期，催化剂可以重复利用，提高转化率，降低生产成本，同时反应过程中无需中和碱洗、水洗等后处理，无污水排放
