According to the method, 1-bromo-undecane and ethylene glycol are used as initial raw materials, common strong base is added, and after heating, a one-pot method is adopted for reaction to finally synthesize the 2-undecyloxy-1-ethanol. The synthesis method disclosed by the invention is mild and controllable in reaction condition, mainly adopts cheap raw materials, is low in product cost and high in reaction yield, and can be suitable for industrial large-scale production, and the product content can reach 99% or above (GC detection). In addition, the 2-undecyloxy-1-ethanol synthesized by the method can be used as a sex pheromone component of the monochamus alternatus hope, and can be prepared into a lure to be combined with a trap to effectively trap male monochamus alternatus hope. Therefore, the method disclosed by the invention has great market application and popularization prospects.

Method for preparing monochamus alternates hope aggregation pheromone

The invention discloses a method for preparing monochamus alternates hope aggregation pheromone. The method comprises the following steps: mixing two compounds into a first solvent, and carrying out asubstitution reaction under an alkali condition so as to obtain a third compound; mixing the third compound and the fourth compound in a second solvent, and carrying out a substitution reaction underan alkali condition under the action of a first catalyst so as to obtain a fifth compound; mixing the fifth compound with a third solvent, and carrying out deprotection under an acid condition underthe action of a second catalyst, thereby obtaining a final compound, namely the monochamus alternates hope aggregation pheromone. According to the method, 2-tert-butoxyethanol is adopted as an initialraw material, and the final product undecyl ethanol can be prepared through sulfonic acid esterification, undecyl alcohol substitution and deprotection reactions. The method is simple and convenientin process operation, high in yield, low in cost, good in weight and capable of meeting industrial production requirements.

Nematocide composition comprising 2-(1-alkyloxy)-1-ethanol compounds

The present invention relates to a method for manufacturing a 2-(1-alkyloxy)-1-ethanol compound and a nematicide compound comprising compounds having alkyl groups with different carbon number. When treated with Meloidogyne or Bursaphelenchus xylophilus, compounds excluding 2-(1-undecyloxy)-1-ethanol as Cerambycidae aggregation pheromone can be used as the nematicide compound for controlling pine wilt, and there is an excellent effect of controlling the root-knot nematode which causes great damages to horticulture, flowers, trees and the like by using the composition.COPYRIGHT KIPO 2017
