preparation example Construction

[0048] The preparation process of the n-dodecyl-glucoside is as follows: take anhydrous glucose, n-dodecyl alcohol, and a catalyst in a three-necked flask, install a condenser tube, a thermometer, and a stirring device, and slowly The temperature was raised to 110°C, and the reaction was carried out at a constant temperature for 4 hours. Take out 2mL of the reactant, add 5% sodium hydroxide solution to adjust the pH value to 8, use Fehling's reagent to judge the end point of the reaction, if a large amount of brick red precipitate is formed, the reaction is not complete, continue the reaction until a small amount of precipitate is formed after adding Fehling's reagent The reaction is over. The system was cooled to 70° C., and the pH value of the system was adjusted to 8 by adding 5% sodium hydroxide solution. The unreacted and excess n-dodecyl alcohol in the product is separated by vacuum rotary evaporation, and the residual n-dodecyl alcohol is further extracted with a chlor...

Abstract

The invention relates to the technical field of pesticides, and particularly provides a pesticide adjuvant and a preparation method thereof. The first aspect of the invention provides a pesticide auxiliary agent which at least comprises the following preparation raw materials in parts by weight: 4-30 parts of calcium dodecylbenzene sulfonate, 1-20 parts of nonylphenol polyoxyethylene ether, 1-20 parts of an emulsifier, 0.1-10 parts of dodecylbenzene sulfonic acid, 0.1-6 parts of triethanolamine, 2-20 parts of a wetting agent and 30-100 parts of a solvent. The wetting agent is alkyl glycoside with a carbon chain length of 8-14.

Description

technical field [0001] The invention relates to the technical field of pesticides, and more specifically, the invention provides a pesticide adjuvant and a preparation method thereof. Background technique [0002] Agriculture is the foundation of the national economy, and pesticides play an important role in the process of agricultural development. Pesticide adjuvants refer to the general term for various auxiliary materials used in the processing and application of pesticide formulations. Although the adjuvants themselves generally have no biological activity, However, it is an indispensable additive in the formulation of dosage forms or when administering medicines. [0003] Regardless of the method of application, the drug effect can only be exerted when the target contacts and absorbs the pesticide. Cloth and penetration are directly related. Pesticide adjuvants themselves have no biological activity, but they can enhance the control effect of pesticides. The adjuvant...
