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 rosin and its derivatives. The rosin processing method is mainly to separate the rosin and turpentine contained in the rosin by distillation to produce rosin and turpentine, which are used in electronics, In ink, synthetic rubber, adhesive, paint, food and other industries, a few products such as turpentine are also used in pesticide preparations, but due to high price and unsatisfactory solubility, the application is greatly restricted

Embodiment 1

[0033] Weigh 100 kg of masson pine pine resin, crush it and add it to the fat storage tank to remove water; mix the dehydrated pine resin with 0.5 kg of MGG catalytic cracking catalyst; in the isolation of air, ultrasonic frequency 100KHz, output power 500W, temperature 250 ℃ Under the condition of ultra-sonic cracking for 4 hours, the lysate was washed with 10 kg of 5% liquid alkali aqueous solution, and the oil and water were separated by standing. The separated oil phase was fractionated by a fractionating tower, and the fraction between 80 and 260 ° C was collected; the water separator was dehydrated (the mass percent of water in the cut is 0.35%), obtain 79 kilograms of cuts, add 0.8 kilograms of antioxidant 2 in the cuts, 6-di-tert-butyl-p-cresol dissolves evenly, prepares and obtains the plant source green solvent.

[0034] The composition of the detected plant source green solvent is pinene containing 28% by mass, D-limonene by 30% by mass, longifolene by 9% by mass, ca...

Embodiment 2

[0036] Weigh 100 kg of masson pine resin, crush it and add it to the fat storage tank to remove water; mix the dehydrated resin with 0.5 kg of H4[SiW12O40]xH2O silicotungstic acid (x is 1-12) catalyst; , under the conditions of ultrasonic frequency 100KHz, output power 500W, and temperature 250°C, ultrasonically cracked for 5 hours, washed the lysate with 15 kg of 3% liquid alkali aqueous solution, left standing for oil-water separation, and the separated oil phase was fractionated by a fractionating tower, collected Distillate between 80~260 DEG C; dehydration by water separator (0.35% by mass of water in the distillate), obtain 80 kilograms of distillate, add 0.81 kilogram of antioxidant butyl hydroxyanisole in distillate and dissolve evenly, prepare to obtain plant source Green environmental protection solvent.

[0037] The composition of the detected plant source green solvent is 31% by mass of pinene, 29% by mass of D-limonene, 7% by mass of longifolene, 12% by mass of ca...

Embodiment 3

[0039] Take by weighing 100 kilograms of masson pine turpentine, add in the fat storage pool after pulverizing, remove moisture; The turpentine after dehydration is mixed with 0.5 kilogram of H4[SiMo12O40]xH2O molybdosilicic acid (x is 1-12) catalyst mixes; Under the conditions of ultrasonic frequency 50KHz, output power 500W, and temperature 250°C, ultrasonic cracking was performed for 5 hours, the lysate was washed with 8 kg of 6% liquid alkali aqueous solution, and the oil and water were left to separate. The separated oil phase was fractionated by a fractionating tower and collected Distillate between 80~260 ℃; dehydration by water separator (0.35% by mass of water in the distillate), obtain distillate 78 kilograms, add 0.79 kilograms of antioxidant butyl hydroxyanisole in distillate and dissolve evenly, prepare to obtain plant source Green environmental protection solvent.

[0040] The composition of the detected plant source green solvent is pinene containing 28% by mass...

Abstract

The invention provides a method for preparing a botanical environment-friendly solvent, and in particular relates to a method for preparing the botanical environment-friendly solvent from pine resin through ultrasonic catalytic cracking. Raw materials for preparing the botanical environment-friendly solvent are all from the pine resin, and have low price; the ultrasonic catalytic cracking method adopted has simple process, mild cracking conditions, environmental protection, and low energy consumption; cracking products are mainly safe and environment-friendly components such as terpene compounds and the like; and the obtained botanical environment-friendly solvent has high yield, low price, no conflict with human, and safety and environmental protection.

Description

technical field [0001] The invention relates to a method for preparing a plant-derived solvent, in particular to a method for preparing a solvent for processing pesticide preparations by using rosin as a raw material. Background technique [0002] For a long time, the production of 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 It is an emulsifiable type of formulation (the organic solvent used in the emulsifiable type pesticide accounts for about 80% of all organic solvents used in pesticides), and these solvents have the disadvantages of low flash point, flammability, and high toxicity to humans and the environment, while organic solvents and Adjuvants will all enter the environment during the use of pesticides. In my country alone, 200,000 to 300,000 tons of "triphenyl" are used in the processing of pesticide...
