| titleOfInvention | PROCEDURE FOR THE PREPARATION OF ALKYLAROMATIC HYDROCARBONS. |
| abstract | Process for the preparation of alkylaromatic hydrocarbons, suitable for the production of perfectly biodegradable synthetic detergents, characterized in that heavy fractions of petroleum or gas-oil of any composition are submitted, with a boiling point range of 300-600ยบ C, such as example fractions of fuel oil, heavy naphtha, etc., to cracking under such conditions that produce the largest amount of monoolefins with a long chain of carbon atoms in the resulting hydrocarbon mixture, of which hydrocarbon mixture, produced by the cracking, a fraction is separated by fractional distillation, comprising, among others, linear olefins with the number of carbon atoms ranging from 8 to 15; after that said fraction is conveniently treated with urea in the presence of a solvent for the urea and optionally in the presence of a diluent for the hydrocarbons, so that the urea selectively forms an adduct with the linear olefins; after that said adduct is separated, it is then decomposed in the presence of an aromatic hydrocarbon capable of maintaining said olefins in solution, while permitting the separation of the urea by means of precipitation; after that, the alkylation reaction between said aromatic hydrocarbon and the straight chain olefins dissolved therein, directly within the olefin solution in the free aromatic hydrocarbon of the urea, is carried out after the usual ones have been added to the solution. alkylation catalysts of the Friedel-Crafts type.
