Plant source green and environment-friendly solvent and preparation thereof

Abstract

The invention is suitable for the technical field of pesticide solvents, provides a plant source green and environment-friendly solvent and simultaneously provides a method for preparing the plant source green and environment-friendly solvent from destructive distillation turpentine. The plant source green and environment-friendly solvent comprises the following components in percentage by mass: 10 to 40 percent of pinene, 10 to 40 percent of D-limonene, 5 to 15 percent of longifolene, 5 to 15 percent of camphene, 3 to 15 percent of dehydroabietic acid, 1 to 10 percent of pinane and 0 to 2 percent of antioxygen. The preparation method comprises the following steps: (1) pulverizing and dehydrating the turpentine; (2) performing dry distillation and collecting lysate; (3) washing the turpentine by alkali liquor, standing the washed turpentine for fractional distillation; (4) performing dehydration; and (5) adding the antioxygen for uniform dissolution to prepare the plant source green and environment-friendly solvent. A raw material adopted by the solvent is the turpentine of pine trees, and is low in cost; the preparation method has simple process, environmental protection and lessenergy consumption; decomposition components give priority to safe and environment-friendly components, such as a terpene compound and the like and can be controlled; and the plant source green and environment-friendly solvent has low production cost, safety and environmental protection, and is beneficial for people.

Description

technical field

[0001] The invention belongs to the technical field of pesticide solvents, and in particular relates to a plant source green and environment-friendly solvent, and also relates to a method for preparing the plant source green and environment-friendly solvent by dry distillation of turpentine. Background technique

[0002] For a long time, the production of domestic pesticide liquid preparations has widely used aromatic hydrocarbons (including benzene, toluene, xylene, etc.) organic solvents, polar solvents (such as N,N-dimethylformamide (DMF), cyclohexanone, etc.), Especially the emulsifiable type formulation (organic solvent used in the emulsifiable type pesticide accounts for about 80% of all pesticide organic solvents), the annual consumption of "triphenyl" is as high as 200,000-300,000 tons, but these solvents have low flash point, Inflammable, explosive and highly toxic to humans and the environment. Organic solvents and additives will all enter the envi...
