Abstract
A kind of liquid aluminum trichloride catalyst and preparation technology thereof are characterized in being made up of methylbenzene, solid alchlor and hydrogen chloride gas.Catalyst of the present invention in use, have active strong, consumption is few, low temperature reacts, applicability is wide, can replace the solid aluminum trichloride catalyst.Good dispersion in reaction makes reaction thoroughly, and product yield improves 5-10%, and this catalyst is steady, easy to control in reaction.Also have in addition and make simply, easy to use, available pump is carried, and improves advantages such as operating environment.
Description
The invention belongs to the catalyst processing technique field, specifically a kind of liquid aluminum trichloride catalyst of chemical industry synthesized polymer reaction.
The aluminum trichloride catalyst that in synthetic reaction, adopts at present, its big portion uses the solid alchlor, as the used catalyst of alpha-olefin polymerization is exactly the solid alchlor, although external relevant patent has been introduced the solid alchlor is added in the dimethylbenzene, add in the alpha-olefin again and react, but the solid alchlor is a suspension in dimethylbenzene, is not true solution.Be among the 90101107.X at number of patent application in addition, introduced the preparation technology about liquid aluminum trichloride, the defective of this liquid aluminum trichloride catalyst maximum is exactly: can not long preservation, and prepared finished catalyst must use at once.Also there are severe reaction conditions, deficiency that cost is high in addition.
The purpose of this invention is to provide a kind of liquid aluminum trichloride catalyst of being convenient to long preservation, good stability.
The object of the present invention is achieved like this: its preparation technology is: the methylbenzene of 35-70 kilogram is added in the enamel still of band stirring, adding 30-65 kilogram solid alchlor again stirs, hydrogen chloride gas with the 3-8 kilogram feeds in alchlor and the methylbenzene mixed liquor at normal temperatures and pressures, cause the solid alchlor all to dissolve, generate ternary liquid aluminum trichloride complex compound catalyst, through 200 order stainless (steel) wire filtering and impurity removing matter, the liquid aluminum trichloride catalyst that can to obtain active alchlor content be 30-65%.Pack in the airtight Plastic Drum, can store and year do not change half a year to two.This liquid aluminum trichloride catalyst belongs to acidic materials, and corrosiveness is arranged, and meets water decomposition, can lose catalytic activity.
Catalyst of the present invention in use, have active strong, consumption is few, low temperature just can react, applicability is wide, and is every when making catalyst reaction with the solid alchlor, an all available catalyst.Owing to being therefore good dispersion in reaction of liquid, make reaction thoroughly, product yield improves 5-10%, and this catalyst is steady, easy to control in reaction.The present invention also has manufacturing in addition simply, does not need the energy and special installation, easy to use, and available pump is carried, and improves advantages such as operating environment.
The present invention can be made into liquid aluminum trichloride catalyst lowest activity alchlor content 30% as required to high activity alchlor 65%, and the scope of application is wide.
Below will the invention will be further described by embodiment.
