Method 1: n-decanoic acid n-decyl ester was prepared as follows: 1 mol n-decanol and 1 mol n-decanoic acid and 0.22 g 0.22 g 2001 (tin oxalate) were heated in an aqueous separator at a temperature of 240 C for 3 hours. The product was evaporated via a 30 cm column (153-168 C, 0.8 mbar). The product was a colorless, odorless oil.
Method 2: In a reaction kettle, 348 parts of decanoic acid, 383 parts of decanol, 0.30 parts of catalyst stannous oxide, 1.0 part of activated carbon were added sequentially, N2 was passed, the temperature was gradually increased under stirring, and the reaction was held for 6 hours at a temperature of 160-170C. The reaction-generated water was distilled, and after the end of the holding time, the product was transferred to a deethanolization kettle, and the product was held at a temperature of 160C and a vacuum of 100 Pa for 30 minutes, and then the temperature was reduced to 70 Decanoic acid decanol ester was obtained by filtration at , and the esterification rate was 99.3%.
