Abstract

The present invention is method of eliminating aluminum trichloride and purifying product in C5 petroleum resin producing process with C5 fraction as material and aluminum trichloride as catalyst. The method includes adding 3-12 % concentration sodium hydroxide solution in 20-60 vol% of the resin liquid into the molten C5 petroleum resin liquid, heating the mixture to 90-120 deg.c and stirring for the resin liquid and the sodium hydroxide solution to react, cooling to room temperature for separating oil phase and water phase and solidifying petroleum resin, washing the solidified petroleum resin with water, crushing solidified petroleum resin into 10-100 micron powder, soaking in distilled water containing non-ionic surfactant for 20-24 hr, washing with water to neutrality, eliminating water, and vacuum drying to obtain purified C5 petroleum resin.

Description

technical field [0001] The invention belongs to the field of petrochemical industry, and relates to a method for removing catalysts in the production process of petroleum resin to purify products, in particular to a by-product C in the production of ethylene 5 The distillate is used as raw material, and aluminum chloride is used as a catalyst to prepare C 5 A method for removing aluminum trichloride and purifying products in the production process of petroleum resin. Background technique [0002] C 5 Petroleum resin is cracked C by-product of ethylene plant 5 The distillate was separated as raw material and used anhydrous AlCl 3 or BF 3 The ether complex is the resin obtained after cationic polymerization of the catalyst. cationic polymerized C 5 Petroleum resins contain catalysts, unpolymerized monomers and oligomers with very small molecular weights, which need to be removed by suitable methods to obtain good quality products. Catalyst removal is the synthesis of C ...
