Containers with low permeability to hydrocarbon vapors, and in particular to fuel vapors, having at least one surface coated with a p-xylylene polymer and/or its derivatives. The containers find use in the fuel industry and, in particular, in the automobile industry for the production of fuel tanks for cars, commercial vehicles, and motorcycles.

Containers having low permeability to hydrocarbon vapors and process of

Ethylene is polymerized in a gaseous phase and in contact with a Ziegler/Natta type solid catalyst capable of producing polyethylene in the form of granules having an easily controllable and homogeneous granulometric size, the polymerization being conducted in a tubular reactor in which the catalyst and the polymer granules which are formed are carried along the reactor by the flow of the gas.

Process for polymerizing ethylene in a gaseous phase

A process is provided for the production of formaldehyde by oxidizing methanol in the presence of a catalyst containing metal oxides wherein the feed stream is admixed, outside the reaction stage, with at least one portion of the reaction product.

Process for the production of formaldehyde

Apparatus and process for the production of formaldehyde by catalytic conversion of methanol wherein a reaction vessel has an outlet means and an inlet injector nozzle means at one end thereof, the injector means feeding reactants to a diffuser member, the diffuser member having at its other end an annular catalyst bed, and means in said reaction vessel for circulating reactants products passing from the catalyst bed to the outlet means and to the injector means-diffuser member for recirculation therethrough.
