    Abstract: With a method or a device for producing 1,2-dichloroethane or ethylene (di)chloride (EDC) with the use of a circulating reaction medium and a catalyst, whereby ethylene and chlorine are supplied to the reaction medium, the goal is to permit the catalytic chlorination of ethylene in a manner that is particularly gentle to the product.This is achieved in terms of the method and by other means in that the ethylene or chlorine gas are introduced into the reaction medium by means of microporous gas diffuser elements for producing gas bubbles with a diameter of 0.3 to 3 mm.

    Abstract: The present invention relates to a compound of the LaMO3 type, M being aluminum, gallium or indium, in the form of a powder or in sintered form, its process of preparation and its use as an oxygen conductor. The compound in powder form is capable of achieving, by pressureless sintering, a density of at least 93% of the theoretical density and of giving a sintered compound substantially free of any electrically active secondary phase of the grain boundaries. The compound in powder form is obtained by the reaction of the salts of lanthanum and of the element M with a base, and then the separation and calcining of the precipitate obtained. It may also be obtained by mixing, in a liquid medium, salts of lanthanum, and of the element M and, optionally, of a base, and then spray-drying and calcining the precipitate obtained. The sintered compound may be used in any application requiring an oxygen-conducting material in oxide form, such as solid-oxide fuel cells.
