Green solvent for pesticide and application of green solvent

Abstract

The invention relates to a green solvent for pesticide and an application of the green solvent. The green solvent for pesticide is a composition in which natural oils serve as the primary components and gemini pyrrolidone serves as the cosolvent. The green solvent for pesticide has excellent dissolubility and application stability and is used for replacing the poisonous and harmful benzenes solvent in traditional pesticide preparation. The green solvent for pesticide is safe to human body, domestic animals and environment. The green solvent comprises the following components by weight percent: 70.0-99.0% of natural oils, 0.1-20.0% of cosolvent and 0-10.0% of anti-freezing agent. Such a green solvent is prepared by uniformly mixing the components according to a certain weight percent. The green solvent for pesticide has the advantages that the preparation process is simple, the solvent use is safe and convenient, the green solvent for pesticide meets the demand of replacing the benzenes solvent in pesticide preparation of national policy, and the green solvent for pesticide is suitable for being applied and popularized in large area.

Description

technical field

[0001] The invention relates to a green solvent for pesticides, which is a composition composed mainly of natural oils and geminipyrrolidone as a cosolvent, has good solubility and application stability, and is used to replace toxic and harmful solvents in traditional pesticide formulations. Benzene solvents. The invention also relates to the application of the green solvent in pesticides. Background technique

[0002] my country consumes more than 300,000 tons of pesticide technical materials every year, and makes about 2 million tons of various preparations, of which emulsifiable concentrate preparations account for about half, that is, 1 million tons. The harm of solvents to the human body and the environment has become an important factor restricting the development of a harmonious society. International pesticide formulations are developing in the direction of high efficiency, environmental protection, convenience, economy, and low pollution. Environment...
