Problems solved by technology

On the other hand, more than 3,000 forestry chemical companies in the country are mainly engaged in the deep processing and application of pine resin and its derivatives. The annual production capacity is seriously insufficient, which affects the income of forestry workers and the expansion of reproduction of enterprises. The problem of product outlets needs to be solved urgently.
[0008] However, it is difficult to process rosin into an environmentally friendly solvent: although rosin can be catalytically pyrolyzed at a temperature higher than 400 ° C, carbon-carbon cracking and rearrangement occur, and the main products are methyl-substituted cyclopentane and toluene , naphthalene, methylnaphthalene, α-pinene, D-limonene, phenol, organic acid, etc., but need to consume a large amount of heat energy; decarboxylation and lactonization reactions occur in rosin under mild conditions, and good plants cannot be obtained Source green solvent components

Abstract

The invention provides a green plant source environmental protection solvent and a preparation method thereof. The environmental protection solvent is obtained by the microwave cracking of turpentineunder the action of a certain catalyst. The solvent comprises 15wt% to 35wt% of alpha pinene, 15wt% to 40wt% of D-hesperidene, 5wt% to 15wt% of longifolene, 5wt% to 15wt% of camphene, 1wt% to 5wt% ofterpenol and 0 to 2wt% of antioxidant. Compared with the prior art, the raw material of the green plant source environmental protection solvent completely comes from the turpentine of a pine and has low price and simultaneously, a new prospect is supplied to silvichemicals. The solvent as a natural carrier of pesticide replaces an aromatic solvent and a polar solvent with poor safety environmentalprotection, reduces the release of toxic and harmful organic solvents in the environment and has mild and simple preparation condition and low energy consumption.

Description

technical field [0001] The invention relates to a solvent for processing pesticide preparations, in particular to a plant source green solvent derived from pine products and a preparation method thereof. Background technique [0002] At present, domestic pesticide liquid preparations basically need to use organic solvents such as aromatic hydrocarbons, especially emulsifiable concentrate formulations (organic solvents used in emulsifiable concentrate formulation pesticides account for about 80% of all organic solvents used in pesticides), these organic solvents mainly include benzene , toluene, xylene, methanol, etc., and the annual consumption of "triphenyl" is as high as 200,000-300,000 tons. However, these solvents have disadvantages such as low flash point, flammability, and high toxicity to humans and the environment. Organic solvents and additives During the use of pesticides, all of them will enter the environment, causing serious environmental pollution and damaging ...
