Embodiment 1

[0037] Collect C with a boiling point of 40-70°C under normal pressure 5 Alkenes and C with a boiling point of 90-120°C at a vacuum of 0.09 MPa 9 Olefin component; first in the reactor with stirring (stirrer model is 60W, 3000 rpm, Changzhou Guohua Electric Machinery Co.), adding mass percentage is 10% toluene as solvent under the condition of being lower than 10 ℃ , then add 2% AlCl 3 Catalyst; Then in the toluene solvent with the speed of 2 drops / second dripping the C9 that the mass percentage is 30%, then with the speed of 1 drop / second in the toluene solvent, drop the C5 that the mass percentage is 60%; Dropping is completed After that, stir evenly, and react at 60°C for 6 hours to obtain a polymerization solution; pour the reacted polymerization solution into a separatory funnel and perform water washing-alkali washing-water washing at 75°C. It is a 5% NaOH solution, and this process is carried out alternately until the polymerization liquid is washed to neutral; pour t...

Embodiment 2

[0039] Collect C with a boiling point of 40-70°C under normal pressure 5 Alkenes and C with a boiling point of 90-120°C at a vacuum of 0.09 MPa 9 Olefin component; first in a stirred reactor, add 8% by mass of toluene as a solvent at a temperature lower than 10°C, and then add 1% by mass of AlCl 3 Catalyst; Then in the toluene solvent with the speed of 2 drops / second dripping mass percent is after the C9 of 33%, then in the toluene solvent with the speed of 1 drop / second is the C5 that drips the mass percent of 66%; Drops complete Afterwards, stir evenly, and react at 50°C for 5 hours to obtain a polymerization liquid; pour the reacted polymerization liquid into a separatory funnel and perform water washing-alkali washing-water washing at 65-75°C, and this process is carried out alternately until the polymerization liquid Washed to neutral; pour the polymer solution washed to neutral into the reactor, heat and distill the polymerization solution at 0.08Mpa, the heating temper...

Embodiment 3

[0041] Collect C with a boiling point of 40-70°C under normal pressure 5 Alkenes and C with a boiling point of 90-120°C at a vacuum of 0.09 MPa 9 Olefin component; first in a stirred reactor, add 9% by mass of toluene as a solvent at a temperature lower than 10°C, and then add 0.5% by mass of AlCl 3 Catalyst; Then in the toluene solvent with the speed of 2 drops / second dripping mass percent is after the C9 of 16%, then in the toluene solvent with the speed of 1 drop / second drips the C5 that the mass percent is 74.5%; Dropping is finished Afterwards, stir evenly, and react at 40°C for 3 hours to obtain a polymerization solution; pour the reacted polymerization solution into a separatory funnel and perform water washing-alkaline washing-water washing at 65°C, and this process is carried out alternately until the polymerization solution is washed to neutrality; pour the neutralized polymerization solution into the reactor, heat and distill the polymerization solution at 0.09Mpa,...

Abstract

Disclosed is a process for preparing C9 modified C5 petroleum resin, which comprises using C5 as the main raw material, using C9 as the modifying raw material, charging C9 active fraction into C5 active fraction, preparing C9 modified C5 petroleum resin, using AlCl3 as catalyst for copolymerizing C5, C9 petroleum resin.

Description

technical field [0001] The present invention relates to a kind of preparation method of petroleum resin, particularly a kind of C 5 、C 9 Preparation method of copolymerized petroleum resin. Background technique [0002] Petroleum resin was originally developed to replace pine resin and its derivatives. But once it came out, it developed rapidly. In just a few decades, it has already had a considerable production level and output. Especially in the industrially developed countries in the world, there are many specifications of petroleum resin products and the scale of production equipment is very large. For example, there are nine companies producing petroleum resin in Japan, with a production capacity of 1 million tons per year. Exxon, Hercules, and Goodyear in the United States; CdF in France; ICI in Britain and other major petrochemical companies in the world also have petroleum resin production devices. my country Taiwan and South Korea and other places also produce...
