Please select the most similar patent number from A, B, C and D. Which number is?
Disclosed in the invention is a plant growth-regulator containing 6-benzylaminopurine, and the present invention in particular relates to a water-soluble composition containing 6-benzylaminopurine and a preparation thereof; the plant growth-regulating composition comprises the following components with the following weight ratios: A. 0.05-5 parts of 6-benzylaminopurine; B. 10-30 parts of at least one alkaline ingredient selected from tripotassium phosphate, trisodium phosphate, dipotassium hydrogen phosphate, disodium hydrogen phosphate, potassium tripolyphosphate, sodium tripolyphosphate, disodium octaborate tetrahydrate, potassium tetraborate, borax, triethanolamine and ethanolamine; and C. 5-30 parts of at least one chelating agent ingredient selected from disodium EDTA, calcium EDTA, magnesium EDTA, calcium disodium EDTA, magnesium disodium EDTA, sodium citrate and potassium citrate; the present invention can effectively improve the solubility property of 6-benzylaminopurine in water, and improve the efficacy thereof; furthermore, the plant growth-regulating composition containing 6-benzylaminopurine of the present invention can also avoid the adverse effects on the health of the human body caused by using a strong acid or alkali.
A: Provided is a synthesis method for 6-furfurylaminopurine. In the presence of 1,8-diazabicycloundec-7-ene (DBU), furfurylamine and 6-chloropurine undergo a nucleophilic substitution reaction under hexamethyldisilazane reflux conditions to obtain a 6-furfurylaminopurine crude product, and recrystallisation is performed to obtain 6-furfurylaminopurine, the HPLC purity being more than 99.5%, a single impurity being less than 0.1%. The method has a simple path process, a high yield, and no wastewater discharge.
B: Disclosed is a balance growth regulator for plants. The balance growth regulator is characterized by comprising a filling agent and at least four crop growth regulators selected from brassinolide, methyl jasmonate, auxin (heteroauxin), salicylic acid, cytokinin, gibberellic acid, abscisic acid, ethylene and triacontanol. The product provided by the present invention is a plant growth regulator prepared by at least more than four existing endogenous plant growth regulators, so the balance growth regulator can not only be used for greatly increasing the yield, but also used for additionally producing dry matters, has desirable crop disease resistance and adverse resistance, is green and safe, and does no harm to consumers.
C: A vaginal acid-base buffer gel and a preparation method, the gel consisting of the following components by mass: 1%-39% of an oil phase base, 60%-99% of a water phase base, 0.001%-2% of a pH regulator and 0.05%-5% of a bacteriostat, wherein the oil phase base is white petrolatum or liquid paraffin or glyceryl behenate or Span or Tween or glycerol or propylene glycol; the water phase base is hydroxypropyl methylcellulose or carbomer or sodium carboxymethylcellulose or polycarbophil or polyethylene glycol or azone or gelatin or purified water; the pH regulator is citric acid or sodium citrate or sodium hydroxide or hydrochloric acid or triethanolamine or boric acid or borax or sodium dihydrogen phosphate or disodium hydrogen phosphate; and the bacteriostat is benzoic acid or sodium benzoate or benzyl alcohol or benzalkonium bromide or benzalkonium chloride or sorbic acid or potassium sorbate or nipalgin. The prepared product may effectively regulate the original vaginal environment of inflammation, remove vaginal odor and relieve symptoms such as increased vaginal secretions or itching.
D: The present invention relates to the field of heat storage materials. Specifically disclosed is a composite phase change regulator, comprising disodium hydrogen phosphate dodecahydrate, diatomite, polyacrylamide and sodium dodecylbenzene sulfonate. Also provided are a composite phase change heat storage material containing the composite phase change regulator, as well as the preparation for and application of the composite phase change heat storage material. According to the present invention, it is found that the combination of the quaternary active ingredients of the disodium hydrogen phosphate dodecahydrate, the diatomite, the polyacrylamide and the sodium dodecylbenzene sulfonate is synergistic, which may effectively and synergistically improve the problems of phase separation and supercooling of the phase change material, may regulate the crystallization behavior of phase change material crystals, and may assist in improving the phase change behavior of the phase change material. The composition arrangement of the present invention is reasonable, the processing technology is simple, and the heat storage behavior of the material may be directionally regulated. The adaptability is strong, making the invention convenient for large-scale application.
