Example Embodiment
[0011] Put turpentine, toluene, and anhydrous aluminum trichloride into the reactor for polymerization reaction, control the temperature of the reactants with refrigeration system control and self-control technology, after the reaction is completed, inject hot water into the mixed product of the polymerization reaction for hydrolysis and water washing, The catalyst is decomposed by water washing and then discharged with water. After passing the washing, the mixed product of the polymerization reaction is distilled, and the toluene is recovered through the distillation process. The bottom polymer and monomer are extracted during the distillation process, and the obtained is the terpene resin. . The reactor in this embodiment is an enamel reactor with a paddle stirrer and a cooling jacket. The cooling of the reactor is realized by a built-in coil cooling device in the jacket, and the cooling device is placed in the jacket of the reactor. Composed of stainless steel coil tubes, a...

Abstract
The invention discloses a method for preparing terpene resin. The method comprises the following processes of: polymerizing, washing and distilling, wherein the polymerization process comprises the following steps of: putting methylbenzene, turpentine and a catalyst into a stirring reaction kettle to perform polymerization reaction; after batch feeding is finished, keeping the temperature of a mixed material in the reaction kettle; and homogenizing the mixed material by using a circulating pump during temperature-keeping in the polymerization process. Compared with the prior art, the method has the advantages that the degree of polymerization and the yield of products are high, the oxidation resistance of the products is high, the using quantity of the catalyst is low, and the production cost is reduced.
Description
technical field [0001] The invention relates to the technical field of compound preparation, in particular to a method for preparing solid hydrocarbons. Background technique [0002] Terpene resin is a hydrocarbon produced by polymerizing olefins contained in turpentine under the action of a catalyst. It is light yellow, transparent, brittle solid, non-toxic, odorless, radiation resistant, resistant to dilute acid and dilute alkali , Anti-crystallization, strong electrical insulation and other properties, good compatibility with various composites, soluble in benzene, toluene, turpentine, ether and other organic solvents, insoluble in water, formic acid and ethanol, etc. It has a wide range of applications and is widely used in rubber, adhesives, heat-sensitive adhesive tapes, hot-melt coatings, paints, flat inks, packaging, anti-rust oil, chewing gum (food grade) and other industries. The production procedure of existing a kind of terpene resin is to use high-grade turpen...
