Method for synthesizing allyl phenoxyacetate

The invention discloses a method for synthesizing allyl phenoxyacetate. The method comprises: putting phenol, caustic soda flakes and water into a flask in a proportion, carrying out stirring at 80-90DEG C for a reaction for 1-3h, removing a part of water under normal pressure, thoroughly removing water through toluene to obtain a toluene suspension of sodium phenolate, adding sodium chloroacetate into the toluene suspension of sodium phenolate, carrying out heating reflux for a reaction for 3-5h to obtain a toluene suspension of sodium phenoxyacetate, adding chloropropene and a phase transfer catalyst into the toluene suspension of sodium phenoxyacetate, carrying out heating reflux for a reaction for 6-10h, carrying out cooling, filtering to remove the catalyst and the product sodium chloride so that a crude product containing chloropropene and a toluene solvent is obtained, recovering excess chloropropene and toluene solvent from the crude product under normal pressure and carryingout rectification under vacuum to obtain an allyl phenoxyacetate finished product. Compared with the conventional method, the method provided by the invention has a high product yield, is not seriously corroded, produces the minimal amount of waste water and has environmentally friendly processes.

Production method of sodium phenoxyacetate

An embodiment of the invention discloses a production method of sodium phenoxyacetate. The production method comprises steps as follows: (1), raw materials including 38 parts by weight of chloroacetic acid and 50 parts by weight of water are weighed, chloroacetic acid is dissolved in water, and a chloroacetic acid solution is cooled to 0 DEG C; (2), a saturated sodium carbonate solution is added to the chloroacetic acid solution during stirring at the temperature of 0 DEG C until the pH value of the solution is 7-8; (3), 26 parts by weight of phenol and 50 parts by weight of water are added to the mixed solution, a 35% sodium hydroxide solution is added until the pH value is 12, and the mixed solution is heated to 92 DEG C and subjected to a reaction for 0.5 h; (4), the mixed solution is subjected to suction filtration, solids obtained through filtration are washed and dried, and required sodium phenoxyacetate is obtained. The original production technology is improved, by the aid of a simple measure of cooling, hydrolysis of chloroacetic acid is effectively inhibited, the yield of sodium phenoxyacetate is increased, the quantity of impurities in sodium phenoxyacetate is greatly reduced, and the difficulty in purification and impurity removal of a sodium phenoxyacetate product is reduced.

Finding new elicitors that induce resistance in rice to the white-backed planthopper Sogatella furcifera

Herein we report a new way to identify chemical elicitors that induce resistance in rice to herbivores. Using this method, by quantifying the induction of chemicals for GUS activity in a specific screening system that we established previously, 5 candidate elicitors were selected from the 29 designed and synthesized phenoxyalkanoic acid derivatives. Bioassays confirmed that these candidate elicitors could induce plant defense and then repel feeding of white-backed planthopper Sogatella furcifera.
