Phenthoate water emulsion and preparation process thereof

Abstract

The invention discloses phenthoate water emulsion, and relates to the field of agricultural chemicals. The phenthoate water emulsion comprises the following components: 40.0+ / - 2.0% of phenthoate, 5+ / -2% of a stabilizer, 5+ / -2% of an anesthetic, 5-10% of a solvent, 5-10% of an emulgator, 5-10% of a solubilizer, 2-10% of an antifreezing agent and 2-10% of a wetting agent. Dimethylbenzene is not used as the solvent of the phenthoate water emulsion, but the requirement of solubility can be met, and harm to an ecological environment and human health is greatly reduced; the stability of the qualityof pesticide is good, and the phenthoate water emulsion is easy to store and transport; and the pesticide effect is rapid and lasts for a long time.

Description

technical field [0001] The invention relates to the field of agrochemicals, in particular to a rice-rich water emulsion and a preparation process thereof. Background technique [0002] For a long time, due to the extensive use of chemical pesticides, especially the formulation of emulsifiable concentrate, most of the solvents in the product are aromatic hydrocarbons such as benzene, toluene, and xylene. The long-term use year after year has not only caused a serious waste of resources, Moreover, it has caused serious harm to the environment, ecology and food safety, and constituted a certain threat to human health. Therefore, development is beneficial to ecology, environment, replaces traditional organic solvent with water as a class of new dosage form of solvent, more and more is subject to people's attention. [0003] Daofengsan its chemical name: O, O-dimethyl-S-(α-ethoxycarbonylbenzyl) phosphorodithioate. Physical and chemical properties: colorless crystals (the origin...
