Problems solved by technology
At present, the most widely used in industry is the acid-catalyzed polymerization process using Lewis acid as a catalyst. This method has a fast reaction speed and mild reaction conditions. The reactant sticks and is easy to emulsify during the washing process, which makes the separation of the catalyst quite difficult, and a large amount of wastewater containing the catalyst is produced when the catalyst is removed

Embodiment 1
[0022] Add 5 g of aluminum trichloride to 20 ml of anhydrous ether. 3 grams of molecular sieves were dried at 200° C. for 2 hours. Add the dried molecular sieve into the aluminum trichloride-diethyl ether solution, stir for 4 hours, and soak for 12 hours. The above solution was filtered under the protection of nitrogen, and the obtained solid was dried at a constant temperature of 140° C. for 4 hours to obtain the desired supported catalyst A. Wherein the loading of aluminum trichloride is 10-70wt%.
Embodiment 2
[0024] Except that the carrier material molecular sieve was changed to activated carbon, the rest was the same as in Example 1 to obtain the required supported catalyst B. Wherein the loading of aluminum trichloride is 10-40wt%.
Embodiment 3
[0026] Except that the carrier material molecular sieve was changed to silicon dioxide, the rest was the same as in Example 1 to obtain the required supported catalyst C. Wherein the loading of aluminum trichloride is 10-35wt%.

Abstract
The invention relates to a preparation method of C9 petroleum resin. The preparation method comprises the following steps: adding metal halide into waterless ether, stirring for 0.5 to 4 hours to prepare a metal halide-ether solution, soaking a catalyst carrier into the solution, filtering the solution under the protection of nitrogen gas, drying the obtained solid at a constant temperature of 50 to 300 DEG C for 0.5 to 10 hours so as to obtain a loaded metal halide catalyst; adding C9 fraction and the obtained catalyst into a reactor, carrying out reactions for 0.5 to 10 hours at a temperature of 10 to 100 DEG C so as to obtain a polymerization solution, filtering the polymerization solution, and distilling the polymerization solution under a reduced pressure so as to obtain the C9 petroleum resin. The used loaded metal halide catalyst can be easily separated from the polymerization solution and can be used repeatedly. The production cost of catalyst is reduced, no wastewater is generated during the production process, the resin yield is high, and the energy consumption is low. The prepared C9 petroleum resin has a wide application range.
Description
Technical field: [0001] The present invention relates to a C 9 The preparation method of petroleum resin, be specifically related to a kind of adopting loaded metal halide catalyst to prepare C 9 Petroleum resin method. Background technique [0002] C 9 Petroleum resin is generally a thermoplastic resin obtained by polymerizing heavy aromatics by-products from ethylene cracking units as the main raw material in the presence of a catalyst. C 9 Petroleum resin is light yellow to dark brown functional resin, has good water resistance, acid and alkali resistance, good solubility in organic solvents, good compatibility with many other resins, and can be used for coatings, rubber additives, adhesives Agents, printing inks and many other aspects. [0003] Preparation C 9 The commonly used methods of petroleum resin are thermal polymerization, catalytic polymerization and free radical polymerization. At present, the most widely used in industry is the acid-catalyzed polymeriz...
