Abstract: An improved solid Ziegler-Natta type catalyst for the (co)polymerisation of ethylene and α-olefins, particularly in high-temperature processes, such as for example adiabatic solution processes and high-pressure adiabatic processes with elevated productivity, is provided. Said catalyst is obtained by means of an original process comprising dissolving in hydrocarbons, compounds of titanium, magnesium and optionally a metal selected from hafnium and zirconium, and reprecipitating them in two steps in succession, the first of which is chlorination and the second reduction.

Abstract: The invention relates to a new catalytic composition for the alkylation of aromatic compounds with alcohols, or mixtures of alcohols and corresponding olefins, wherein said composition comprises a zeolite of the MTW type and is characterized in that it contains one or more alkaline metals in a total quantity which is less than or equal to 0.02% by weight. The use of said catalyst in the alkylation of aromatic compounds with alcohols, in particular benzene with isopropanol or ethanol, allows the formation, as by-product, of the aldehyde or ketone corresponding to the alcohol used, to be minimized: the formation of reaction by-products of said aldehydes or ketones having a boiling point very close to that of polyalkylation products, is therefore significantly reduced. This provides a considerable advantage in the subsequent transalkylation step for the recovery of said polyalkylates by transformation into the corresponding monoalkylates.
