Description
Technical field
The invention belongs to technical field of pesticide preparations more particularly to a kind of environmental-protecting and high-efficient type propiconazole emulsifiable concentrate and its preparation sides
Method.
Background technique
Missible oil is one of basic dosage form, has many advantages, such as that processing cost is low, preparation is simple, good drug efficacy, but contains in missible oil
There are a large amount of aromatic hydrocarbon solvent, such as toluene, benzene, dimethylbenzene and acetone, these solvents are not only to environment, ecology and food safety
The harm of accumulation property is caused, and there are also stronger volatility and inflammabilities, there are many insecurity factors.Missible oil is thus solved to ask
The fundamental way of topic necessarily finds the safety and environmental protection substitute of aromatic hydrocarbons equal solvent, to complete the green upgrading of missible oil.
Dibasic ester (Du Pont DBE) is referred to as dibasic acid ester mixture, also known as dibasic acid ester, dicarboxylic acids rouge.Be it is a kind of low toxicity,
Low taste, can biodegradable environment protection type high-boiling-point solvent (alembroth).There is preferable solubility property to most pesticides, with mesh
Preceding common composite emulsifier and monomer are easy matching, have freezing point is lower, flash-point is higher, stability is good, to crop without medicine
The features such as harmful and quality is stablized, meets the requirement of green and environment-friendly solvent.It is to substitute benzene,toluene,xylene, acetone etc. in missible oil
Ideal solvent.
Using dibasic ester substitution missible oil in benzene,toluene,xylene, acetone equal solvent when, in kind and dosage with virtue
Hydrocarbon solvent is substantially suitable, and adaptability is wider.There is difference on specific emulsifier monomer, appropriate adjustment when use.Base
Originally it is applicable in existing agricultural emulsifier system, industrial application is simple and easy.
Summary of the invention
