Problems solved by technology

The deep eutectic solution formed by choline chloride (hydrogen bond acceptor) and urea, polyol (hydrogen bond donor) has been studied more at present. This solvent is easy to synthesize, low in price, non-toxic, biodegradable, Environmentally friendly, low volatility, designable structure, high viscosity, large specific gravity, good moisture retention, strong solubility, etc., but so far there has been no report on the application of eutectic solution to agricultural adjuvants

Embodiment 1

[0041] Weigh 100g of choline chloride crystals and 400g of propylene glycol, put them into the reaction kettle, mix well, stir while heating, keep at 60°C for 1 hour, choline chloride and propylene glycol form a transparent liquid, and then add 500g of JI Xiaoli organic Silicone surfactant, keep the temperature at 60°C for 0.5 hours to obtain a clear and transparent viscous liquid.

Embodiment 2

[0043] Weigh 250g of choline chloride crystals, 100g of urea, and 450g of propylene glycol, put them into a reaction kettle, mix evenly, stir while heating, and keep at 80°C for 2 hours. Choline chloride, urea, and propylene glycol form a transparent liquid, and then add 200g of nonylphenol polyoxyethylene ether NP-10 was kept at 60°C for 0.5 hours to obtain a clear and transparent viscous liquid.

Embodiment 3

[0045] Weigh 150g of choline chloride crystals and 650g of polyethylene glycol-200, put them into the reaction kettle, mix evenly, stir while heating, keep at 70°C for 2 hours, choline chloride and polyethylene glycol-200 become transparent Liquid, then add 200g NP-10 surfactant, keep the temperature at 70°C for 1 hour to get a clear and transparent viscous liquid.

Abstract

The invention relates to an agricultural auxiliary agent containing a eutectic solution. The agricultural auxiliary agent comprises the following components in parts by weight: 1-99 parts of a surfactant and 99-1 part of the eutectic solution, wherein the eutectic solution comprises a hydrogen bond acceptor compound and a hydrogen bond donor compound in a mass ratio of 1: (1-10). The invention also relates to application of the agricultural auxiliary agent in promoting medicament absorption. The agricultural auxiliary agent disclosed by the invention is good in stability and strong in moisturizing and dissolving capacities.

Description

technical field [0001] The invention relates to an agricultural adjuvant, in particular to an agricultural adjuvant containing a deep eutectic solution and its application. Background technique [0002] In order to give full play to the effects of insecticides, fungicides, acaricides, herbicides and growth regulators, appropriate agricultural surfactants must be added in the production of pesticides according to the efficiency and safety of pesticide spreading. Surfactants play the role of wetting, dispersing, emulsifying, solubilizing, spreading and defoaming in the preparation process. After it is sprayed on the target in use, it has the following effects: expand the effective contact area of ​​the droplets, narrow the air gap between the solution and the leaf surface, and reduce the diffusion resistance of the cuticle of the leaf; dissolve the pesticide in the sediment, Prevent or delay the formation of crystals in sediments; dissolve or destroy cuticle wax, and act as c...
