Jatropha curcas essence micro-emulsion and preparation technology thereof

Abstract

The invention belongs to the field of pesticides, and specifically relates to a jatropha curcas essence micro-emulsion and a preparation technology thereof. According to the invention, a plurality of emulsifiers, auxiliary solvents, synergists and stabilizing agents are screened, and the jatropha curcas essence micro-emulsion with good stability and good dispersity is prepared. The technology is characterized in that: the jatropha curcas essence micro-emulsion is prepared from components of: 1-40% of jatropha curcas essence (wherein the active component is jatropherol I), 1-30% of an emulsifier, 4-13% of a stabilizing agent, 0.1-5% of a synergist, 10-20% of an auxiliary solvent, 0.01-1% of a pH regulatior, 0.1-5% of an anti-freezing agent, and balance of water. The pesticide provided by the invention is a micro-emulsion with water as a solvent. Therefore, insecurity during production, application, storage and transportation caused by over-commitment of organic solvents is avoided. The micro-emulsion provided by the invention is characterized in high safety and environment friendliness.

Description

technical field

[0001] The invention belongs to the category of preparation techniques of pesticides and insecticides, and relates to a jatropha insecticide dosage form and a preparation technique thereof. Background technique

[0002] Due to the extensive use of chemically synthesized pesticides, various negative effects such as corresponding resistance of pests and rampant pests have been caused. In addition, solvents such as xylene used in conventional pesticide formulations cause secondary pollution to the environment. Therefore, in developed countries, the use of organic solvents in pesticide formulations is increasingly restricted, which impels the continuous renewal of pesticide formulations, and microemulsions use water. It has obvious advantages as a solvent.

[0003] The insecticidal active ingredients in botanical pesticides are mainly derived from the secondary metabolites of plants. Since the secondary metabolites are the result of the co-evolution of the plant...

Examples

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the examples, but not limited to the examples.

[0024] Example 1, fully stir 1g jatropha parent drug and 14g cyclohexanone to make it evenly mixed, add 5g urea and stir evenly, then add 12g Tween-40 and 6g butanobuterol successively, add triethanolamine after fully stirring When the pH value reaches 7.5, 62g of water is finally added and stirred vigorously and heated to 52°C until the mixture becomes transparent, then cooled to room temperature to prepare a 1% jatropha microemulsion.

[0025] Example 2, fully stir 2g jatrophin parent drug and 20g dimethyl sulfoxide to make it evenly mixed, add 5g sodium sorbate and stir evenly, then add 7g phenylethylphenol polyoxyethylene ether phosphate and 7g Pyrobutane, after fully stirring, add hydrochloric acid to adjust the pH value to 6.5, and finally add 59g of water and stir vigorously and heat to 49°C until the mixture becomes transparent, then cool to...
