-
Paragraph 0032-0039, (2021/10/30)
The invention discloses a synthesis method of 2-undecyloxy-1-ethanol, and belongs to the technical field of chemical production. 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.

Paragraph 0046-0049; 0051-0053; 0055-0057; 0059-0061; 0063-0, (2018/10/19)
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.

Paragraph 0023; 0024; 0026; 0027, (2017/07/23)
The present invention relates to a preparation method of 2-(1-alkyloxy)-1-ethanol, and a nematocide composition comprising a 2-(1-alkyloxy)-1-ethanol derivative as an effective component. According to a result of treating root knot nematode or Bursaphelenchus xylophilus with the nematocide, the 2-(1-alkyloxy)-1-ethanol derivative has an effect suitable for using as a nematocide composition, and moreover, has an excellent effect on exterminating root knot nematode and Bursaphelenchus xylophilus which severely damages horticultural products, flowers, trees, etc. by using the composition.COPYRIGHT KIPO 2017
