Preparation method of higher fatty alcohol 2-alkoxy ethanol

The invention provides a preparation method of higher fatty alcohol 2-alkoxy ethanol, and relates to the technical field of organic synthesis, higher fatty alcohol and sulfonyl halide are used as raw materials for cascade reaction, the higher fatty alcohol is completely converted into sulfonate under the action of alkali, and then the sulfonate is subjected to phase transfer reaction under the promotion of a phase transfer catalyst (the used phase transfer catalyst comprises quaternary ammonium salt or crown ether), sulfonate directly performs nucleophilic substitution reaction with ethylene glycol, and the reaction temperature is controlled to complete the reaction within half an hour to obtain the corresponding higher fatty alcohol 2-alkoxy ethanol. The method is low in raw material and reagent cost, simple in process operation, small in pollution, high in product yield and purity, and suitable for large-scale preparation.

Method for preparing monochamus alternates hope aggregation pheromone

The invention discloses a method for preparing monochamus alternates hope aggregation pheromone.
