Abstract

The invention provides a combined solvent and application thereof. The combined solvent comprises the following components in percentage by weight: 1 to 99 percent of terpenoid and 1 to 99 percent of isoparaffin. The combined solvent has good compatibility with pesticides, good safety and environmental performance, high biodegradability, low freezing point and high flash point, is eco-friendly and is safe and reliable for production, storage, transport and use, and can be applied to pesticide preparations.

Description

technical field [0001] The invention belongs to the field of pesticide preparations, in particular to a combined solvent and its application. Background technique [0002] For a long time, aromatic hydrocarbons (including benzene, toluene, xylene, etc.) organic solvents have been widely used in the production of pesticide liquid preparations in China. In the process of production and use, it not only seriously endangers people's health, but also pollutes the environment and endangers the ecological balance of nature. Aromatic organic solvents are mostly derived from petroleum refining products, and petroleum is a non-renewable resource. The price has been rising in recent years, and petroleum resources will continue to be scarce and exhausted. [0003] In 1992, the U.S. government issued regulations prohibiting the use of organic solvents such as toluene and xylene in pesticide preparations. Since then, European countries have successively issued similar regulations; 38 ki...
