Abstract

The invention relates to a missible oil preparation taking secbutyl acetate as a solvent and a preparation method thereof. The missible oil preparation provided by the invention contains no any polluting organic solvents, such as aromatic solvents, and comprises the following components by weight percent: 0.1%-75% of pesticide active ingredients, 0-5% of a cosolvent, 5%-10% of an emulgator and the balance of secbutyl acetate. The pesticide active ingredients, secbutyl acetate, the cosolvent and the emulgator are uniformly, homogeneously and fully stirred, so that the missible oil preparation provided by the invention is acquired. The missible oil preparation disclosed by the invention contains no aromatic organic solvent, and thus the environmental pollution is reduced; the production technique is simple and the energy consumption is low; the grain size of missible oil preparation drops is less than 1.0 micron, the missible oil preparation is high in ingredient dispersity, is uniform, is high in stability, is long in lasting period, is safe in use and causes small environmental pollution, and the use efficiency of host and auxiliary agents is increased.

Description

technical field [0001] The invention relates to a pesticide preparation, in particular to an emulsifiable concentrate preparation using sec-butyl acetate as a solvent and a preparation method thereof. Background technique [0002] At present, domestic pesticide emulsifiable concentrate preparations basically require the use of organic solvents such as aromatic hydrocarbons. These organic solvents mainly include benzene, toluene, xylene, methanol, etc., and the annual consumption is as high as 200,000 to 300,000 tons. However, these solvents have disadvantages such as low flash point, flammability and high toxicity to humans and the environment. Organic solvents and auxiliaries will all enter the environment during the use of pesticides, causing serious environmental pollution and damaging human health. . [0003] The use of green solvents to replace dangerous and toxic benzene solvents is the need for sustainable economic and social development. In terms of the substitutio...
