Problems solved by technology

The aqueous solution of sodium nitrophenolate (or sodium polynitrophenolate) is alkaline, and it is easy to generate insoluble compound nitrophenolate (or polynitrophenolate) when it encounters acidic substances, so it is not easy to compound with acidic pesticides or fertilizers, and the concentration of action is very high. High, improper use can easily cause drug injury
Both Xu Ligen and Zheng Chunming have reported the plant growth regulating activity of triacontanyl phosphate potassium salt, which can increase yield when used in crops such as corn and rice (Xu Ligen et al., Preliminary report on barley application of triacontanyl potassium phosphate field test, Hangzhou University Journal (Natural Science Edition), 1998, 25(3): 89-92 and Zheng Chunming et al., Bioactivity Detection of Potassium Triacontanol Phosphate, Pesticides. 1999, 38(12): 22-23), but The technology or product identical with plant growth regulator of the present invention have not been reported yet

[0027] Synthesis of example 15-nitroguaiacol phosphate potassium salt

[0028]

[0029] Add 16.9g (0.1mol) of 5-nitroguaiacol and 100mL of chloroform into a 250mL reaction flask, stir to dissolve, add 15.2g (0.1mol) of phosphorus oxychloride dropwise at room temperature, stir at room temperature for 1h, and cool in an ice bath. Warm at 0-10°C, add 0.1mol saturated potassium carbonate aqueous solution dropwise, after dropping, stir at room temperature for 2 hours, thin layer chromatography (TLC) detects that 5-nitroguaiacol has completely reacted, control temperature at 20-40°C, add dropwise 20 % potassium hydroxide solution until the pH of the reaction solution was 7, and the solvent and water were distilled off to obtain 22 g of a white powdery solid with a yield of 71%.

[0030] Can prepare o-nitrophenol phosphate potassium salt and p-nitrophenol phosphate potassium salt according to example 1 method.

[0031] Preparation of Example 24-Hydroxycoumarin Phosphate Potassium Salt

[0032]

[0033] Add 16.8g (0.1mol) of 4-hydroxycoumarin, 100mL of ethyl acetate and 0.1mol of triethylamine into a 250mL reaction flask, and add 15.2g (0.1mol) of triethylamine dropwise at 0-10°C. The mixed solution of phosphorus oxychloride and 30mL ethyl acetate, after dripping, stirred at room temperature for 2h, thin layer chromatography (TLC) detected that the raw material point disappeared, filtered out triethylamine hydrochloride, and the filtrate was neutralized to pH with potassium hydroxide solution 7, the solvent and water were distilled off to obtain 20 g of a light yellow powdery solid, with a yield of 68%;

Description

technical field [0001] The invention belongs to the field of pesticide plant growth regulators, and relates to a potassium phosphate plant growth regulator and its application. Background technique [0002] Sodium nitrophenolate is a high-efficiency plant growth regulator commonly used in agriculture at present. It is composed of 5-nitroguaiacol sodium, o-nitrophenolate sodium and p-nitrophenolate sodium. Tianjin University developed sodium polynitrophenolate plant growth regulator by adding 2,4-dinitrophenolate sodium on the basis of complex sodium nitrophenolate. This type of plant growth regulator increases the yield of crops and the survival rate of transplanted plants by accelerating the flow of plant body fluids, enhancing photosynthetic ability, promoting root growth, etc., and has the advantages of fast drug effect and low cost. The aqueous solution of sodium nitrophenolate (or sodium polynitrophenolate) is alkaline, and it is easy to generate insoluble compound nit...
