Dispersants in high-electrolyte solutions

摘要

Embodiments of the present invention disclose a composition of an electrolyte solution comprising a water-soluble active ingredient; a water-insoluble solid active ingredient; and a dispersant that consists of a polyaminoamide resin, a polyoxyalkylene derivative thereof, a polyglycerol derivative thereof, a polycarbamate derivative thereof and a combination thereof.

主权项

1. A composition comprising:
an electrolyte solution having a water-soluble active ingredient; a water-insoluble solid active ingredient selected from the group consisting of a pesticide, a herbicide, an insecticide, an insect repellent, a fungicide, a bactericide, a plant growth regulator, a fertilizer, an acaricide, an anthelmintic, a nematicide, and a combination thereof; a dispersant selected from the group consisting of a polyoxyalkylene derivative of a polyaminoamide resin, wherein the polyaminoamide resin is obtained by thermal condensation of a poly-functional fatty acid with a poly-functional amine and wherein a starting acid for the poly-functional fatty acid is a C2 to a C60 fatty acid; and wherein the polyoxyalkylene derivative is obtained by reacting the polyaminoamide resin with a polyoxyalkylene selected from the group consisting of ethylene oxide, propylene oxide and a mixture thereof at a molar ratio of polyoxyalkylene to polyaminoamide active hydrogens from 2.4 to 4.8; wherein the weight ratio of the dispersant to the water-insoluble solid active ingredient is from 1:50 to 1:5, and the weight ratio of the electrolyte in solution to the water-insoluble solid active ingredient is from 60:1 to 1:1.
