A kind of chlorpyrifos emulsifiable concentrate and preparation method thereof

Abstract

The invention relates to chlorpyrifos missible oil and a preparation method thereof. The chlorpyrifos missible oil comprises the following components in parts by weight: 40-50 parts of a chlorpyrifos active ingredient, 40-50 parts of sec-butyl acetate and 8-12 parts of an emulsifier. According to the chlorpyrifos missible oil and the preparation method thereof disclosed by the invention, sec-butyl acetate is chosen to replace xylene, and the stability of the chlorpyrifos missible oil is improved by adjusting the dosage ratio of sec-butyl acetate and combining with the emulsifier, thus overcoming the defects of high pollution, and poor solubility and stability of existing chlorpyrifos missible oil.

Description

technical field [0001] The invention relates to a chlorpyrifos emulsifiable concentrate and a preparation method thereof, belonging to the field of pesticide emulsifiable concentrate preparations.
