Problems solved by technology

[0003] With the deepening of petroleum resin research, the requirements for petroleum resin in the market are getting higher and higher, and the output of petroleum resin with high quality and high softening point cannot meet the current demand, which brings us inconvenience.
[0004] At the same time, in today's petroleum resin preparation technology, the finished product contains a large amount of impurities and unsaturated bonds, so we generally carry out hydrogenation operation on petroleum resin to improve the quality of petroleum resin, but in the process of hydrogenation, petroleum Chloride ions and sulfur elements in resin will greatly affect the hydrogenation effect of petroleum resin, which will bring us great inconvenience

Abstract

The invention discloses hydrogenated petroleum resin and a preparation method thereof. Generally speaking, at present, all catalysts used for preparing the C5 petroleum resin are aluminum trichloride;however, aluminum trichloride is easy to decompose in water, so that the catalyst is easy to remove incompletely, a large amount of industrial wastewater is generated after the catalyst is used, theenvironment is polluted, and the quality of the generated C5 petroleum resin is influenced by residual chloride ions and aluminum ions in the petroleum resin. Aluminum trichloride reacts with methanesulfonic acid to synthesize aluminum methanesulfonate. The aluminum methanesulfonate does not decompose in water, has a good catalytic effect and high reaction activity, and is an environment-friendlycatalyst. The invention has the advantages of reasonable formula design and simple preparation process. The hydrogenated petroleum resin with good quality is effectively prepared, the softening pointis increased, impurities are reduced, meanwhile, the preparation process is optimized, the cost is saved, and the hydrogenated petroleum resin has better practicability and generalization performance.

Description

technical field [0001] The invention relates to the technical field of petroleum resin processing, in particular to a hydrogenated petroleum resin and a preparation method thereof. Background technique [0002] Petroleum resin is a kind of C5 and C9 fractions produced by petroleum cracking. It is a thermoplastic resin produced by pretreatment, polymerization, distillation and other processes. Petroleum resin is named for its source of petroleum derivatives. It has an acid value Low, good miscibility, water resistance, ethanol resistance and chemical resistance, chemical stability to acid and alkali, and good viscosity adjustment and thermal stability. [0003] With the deepening of petroleum resin research, the requirements for petroleum resin in the market are getting higher and higher, and the output of petroleum resin with high quality and high softening point cannot meet the current demand, which brings us inconvenience. . [0004] At the same time, in today's petroleu...
