| titleOfInvention | Method for synthesizing ester aviation engine oil base oil without acid catalysis |
| abstract | The invention belongs to the technical field of chemical synthesis, and in particular relates to a method for synthesizing ester aviation engine oil base oil without acid catalysis. The following effective steps are included: a. adding the polyhydric alcohol and the linear saturated monocarboxylic acid containing C5～C10 into the vacuum reactor according to the molar ratio of 1:5～8; b. controlling the vacuum degree in the vacuum reactor to be less than 50pa, and the reaction The esterification reaction is carried out at a temperature of 200°C to 280°C; c. Maintain the vacuum degree of the vacuum reactor and the reaction temperature for 6h to 8h, and then the ester aviation engine oil base oil can be obtained. The present invention provides a method for synthesizing ester aviation engine oil base oil without acid catalysis, and utilizes the combination of the molar ratio of polyhydric alcohol and the raw material containing C5-C10 linear saturated monocarboxylic acid, vacuum conditions, reaction temperature and other conditions. , and then replace the use of traditional catalysts, so that the reaction between polyols and low carbonic acid can be quickly reacted without catalysts, and the produced ester aviation engine oil base oil has high yield and good purity. |
