Abstract: A vaporizer device for an inhaler, in particular for an electronic cigarette product or a medical inhaler, comprising: a vaporizer film, which in turn comprises a layer system with a polymer film and at least one metal film which contacts the polymer film over its surface and is designed as a heating element a liquid reservoir, and a wick structure, which is configured to supply the vaporizer film with liquid from the liquid reservoir, wherein the vaporizer film comprises at least one first receiving opening for receiving liquid and at least one dispensing opening for dispensing vaporized liquid, wherein the vaporizer film is in contact with the wick structure via the base surface, wherein the vaporizer film forms at least one supply channel, via which the at least one first receiving opening can be supplied with liquid from the wick structure.

Abstract: Organic and/or inorganic substances and water are thermally separated from contaminated materials, solid aggregates, the contaminated material is pretreated and is subsequently heated in a directly or indirectly heated furnace, which includes a rotary kiln, a fluidized bed furnace or a floating zone reactor, and during the heating the material is treated with recycled hot gases or recycled hot steam and with oxidizing agents. The exiting processing gases, which contain water vapor, are dedusted, and 80 to 90% by volume of the water vapor-containing processing gases are recycled to the furnace to act as entraining gas. The remaining water vapor-containing processing gases are condensed, the resulting liquid phase is withdrawn, and pollutants are removed from the withdrawn liquid phase by a wet chemical or physical processing.

Abstract: A process for the tertiary dealkylation of a tertiary alkyl containing m- and/or p-cresol wherein a tertiary alkyl containing m- and/or p-cresol is continously introduced into a reaction vessel with a small amount of sulfuric acid or an quivalent amount of a sulfonic acid and the reaction vessel contains a high concentration of m- and/or p-cresol or a high boiling phenol which under the prevailing reaction conditions is not substantially vaporized from the reaction mixture. The reaction mixture is maintained at a temperature of no greater than 230.degree. C. The reaction products are withdrawn continuously from the reactor (and separated into its components) and at the same time a small amount of the reaction mixture being withdrawn intermittently or continously from the reactor.

Abstract: A process for the continuous preparation of a ditertiary butylcresol wherein m- or p-cresol is reacted with isobutene at elevated temperature using H.sub.2 SO.sub.4 as catalyst wherein the process is carried out stepwise by introducing stepwise into a reaction mixture comprising substantially all of the cresol to be reacted with isobutene. The total amount of isobutene introduced is introduced such that less isobutene is charged in a last stage of the process than in the first stage thereof. Thereafter the catalyst is deactivated.

Abstract: A process for the removal of acids and potential acid-forming agents from a composition containing such acids and potential acid-forming agents and an alkylphenol which composition is obtained by reacting phenols with alkenes in the presence of sulfuric acid or a sulfonic acid, and for treating the effluent thereby obtained, the process being characterized by the steps of:(a) extracting a major amount of the acid constituents from the alkylphenol mixture by means of water;(b) treating the alkylphenol mixture with a dilute aqueous alkali solution in an amount such that the alkali is insufficient to neutralize all the acid originally present in the alkylphenol mixture,(c) separating the alkylphenol mixture from the aqueous alkali solution;(d) combining the aqueous phases obtained from steps (a) and (b);(e) heating the combined aqueous phases to a temperature of 100.degree. to 200.degree. C,(f) separating off the organic phase obtained in step (e); and(g) discharging the aqueous phase.
