Example Embodiment
[0010] Example one:
[0011] The method for synthesizing terpene resin includes the following steps to synthesize 1 ton of terpene resin: after the catalyst is added to the solvent and mixed uniformly, the raw material is slowly dropped under low temperature conditions, where the raw material is the heavy turpentine which is fractionated under vacuum and reduced pressure. The product contains 65%-70% β-phellandrene and the solvent is toluene. After adding 0.09 tons of anhydrous aluminum trichloride to 1.2 tons of toluene and mixing, then 1.5 tons of 65%-70% content The raw material of β-phellandrene is slowly added dropwise to carry out low-temperature polymerization. The temperature in the reactor is controlled at -15°C~-5°C. After 4 hours, it is hydrolyzed, washed with water, and synthesized after distillation. Solid terpene resin.
Example Embodiment
[0012] Embodiment two:
[0013] The method for synthesizing terpene resin includes the following steps to synthesize 1 ton of terpene resin: after the catalyst is added to the solvent and mixed uniformly, the raw material is slowly dropped under low temperature conditions, where the raw material is the heavy turpentine which is fractionated under vacuum and reduced pressure. The product contains 75%-80% β-phellandrene and the solvent is toluene. After adding 0.065 tons of anhydrous aluminum trichloride to 1.56 tons of toluene and mixing, then 1.3 tons of 75%-80% content The raw material of β-phellandrene is slowly added dropwise to carry out low-temperature polymerization. The temperature in the reactor is controlled at -15°C~-5°C. After 8 hours, it is hydrolyzed, washed with water, and then synthesized after distillation. Solid terpene resin.
Example Embodiment
[0014] Embodiment three:
[0015] The method for synthesizing terpene resin includes the following steps to synthesize 1 ton of terpene resin: After the catalyst is added to the solvent and mixed uniformly, the raw materials are slowly dropped under low temperature conditions, where the raw materials are heavy turpentine and fractionated under vacuum. The product contains 75%-80% β-phellandrene, and the solvent is toluene. Add 0.052 tons of anhydrous aluminum trichloride and 0.013 tons of anhydrous antimony trichloride to 1.33 tons of toluene. , And then 1.33 tons of the raw material of β-phellandrene with a content of 75%-80% is slowly added dropwise to carry out low-temperature polymerization. The temperature in the reactor is controlled at -15°C~-5°C for 6 hours , And then hydrolyzed, washed with water, and distilled to synthesize solid terpene resin.
