Problems solved by technology

When compound A is applied in the market, it is difficult to dissolve the original drug and derivative impurities. Generally, it is difficult to dissolve compound A and derivative impurities with alkane series solvents, even if some other types of solvents can be used to dissolve the compound A and its dissolution, but because compound A is normally used in aerosols, and propylene butane is often used as filling gas in aerosols, even if other types of solvents are used to dissolve, wait until it is filled into the aerosol can, because Subtle differences between compound A and derivative impurities, derivative impurities will slowly precipitate out over a long period of time, and even cause the pre

Abstract

A provided pesticide mother liquid comprises, in percent by weight, 1%-20% of n active composition A, 1%-98% of one solvent B selected from C8-C19 low alkane solvents, 1%-98% of one or more cosolvents C selected from diethyl phthalate, diisopropyl adipate, dibutyl adipate, epoxy soybean oil, epoxidized fatty acid methyl esters, soybean oil, isopropyl myristate, tributyl citrate, dimethyl carbonate, n-butanol, n-amyl alcohol and n-octyl alcohol; and the active composition A is a pyrethroid compound shown as a formula (X1). The pesticide mother liquid solves multiple technological problems that the active composition A is difficult to dissolve in low alkane solvents and generates a large amount of impurities after being dissolved and influences downstream usage.

Description

technical field [0001] The invention relates to an insecticide mother liquor and its preparation method and application. Background technique [0002] D-2,2-Dimethyl-3-trans-(2,2-dichlorovinyl)cyclopropanecarboxylic acid-(s)-2-methyl-3(2-propargyl)-4 -Oxo-cyclopent-2-enyl ester is a new type of pyrethroid, referred to as D-trans permethrin, hereinafter referred to as compound A, the activity of this compound is higher than that of ordinary d-transmethrin 10 times, but due to factors such as its own solubility, it has not been widely promoted. When compound A is applied on the market, it is difficult to dissolve the original drug and derivative impurities. Generally, it is difficult to dissolve compound A and derivative impurities with alkane series solvents, even if some other types of solvents can be used to dissolve the compound A and its dissolution, but because compound A is normally used in aerosols, and propylene butane is often used as filling gas in aerosols, even ...
