Abstract

A composite includes a first preform and a second preform spaced from and in overlying relationship to the first preform. The second preform defines at least one first opening extending therethrough along an axis transverse to the first preform. A first surface layer is disposed adjacent to the second preform and on an opposite side of the second preform from the first preform. A polymeric composition including the reaction product of an isocyanate component and an isocyanate-reactive component is disposed between the first preform and the second preform. The polymeric composition adheres the first surface layer to the second preform through the at least one first opening. The surface layer is adhered to the second preform during molding of the composite article and in the absence of additional adhesive, thereby reducing production time and cost of the composite article.

Abstract

(Chloro)hydrocarbon-free hydrogen chloride and phosgene-free (chloro)hydrocarbons are recovered from a hydrogen chloride stream having (chloro)hydrocarbons and phosgene. The recovery involves connecting a first adsorber and a second adsorber in series and passing the fresh hydrogen chloride stream comprising phosgene and (chloro)hydrocarbons firstly through the first adsorber and subsequently through the second adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the first adsorber, passing the fresh hydrogen chloride stream through the second adsorber while the first adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration, passing the fresh hydrogen chloride stream firstly through the second adsorber and subsequently through the regenerated first adsorber until essentially no more (chloro)hydrocarbon is adsorbed by the second adsorber, and passing the fresh hydrogen chloride stream through the first adsorber while the second adsorber is regenerated, with essentially phosgene-free (chloro)hydrocarbon being obtained in the regeneration.

Abstract

The invention relates to a process for preparing polymethylol compounds of the formula (I) where the radicals R are each, independently of one another, a further methylol group or an alkyl group having from 1 to 22 carbon atoms or an aryl or aralkyl group having from 6 to 22 carbon atoms, by condensation of aldehydes having from 2 to 24 carbon atoms with formaldehyde in an aldol reaction using tertiary amines as catalyst to form alkanals of the formula (II) where the radicals R each independently have one of the abovementioned meanings, and subsequent hydrogenation of the latter. The particular inventive feature of this process is that the aldol reaction is carried out using an aqueous formaldehyde solution having a formic acid content of <150 ppm and preferably <100 ppm. In this way of carrying out the process, the formation of by-products can advantageously be prevented in a targeted manner and the yield of the desired polymethylol compound can thereby be increased.

Abstract

60) is the weight of 0.9% by weight sodium chloride solution absorbed by 70 g of the water-absorbing polymeric particles in 60 minutes, wherein the water-absorbing polymeric particles are situated, during measurement, in a circularly round vessel which has an internal diameter of 6 cm and is sealed at its lower end by a sieve base of 36 μm mesh size, and the sieve base is in atmospheric contact with 0.9% by weight sodium chloride solution, processes for their preparation and also their use in hygiene articles and packaging materials.

Abstract

A process for heterogeneously catalyzed partial dehydrogenation of a hydrocarbon, in which a reaction gas mixture input stream comprising the hydrocarbon to be dehydrogenated is conducted through a fixed catalyst bed disposed in a shaft and the reaction gas mixture input stream is obtained in the shaft by metering an input gas II comprising molecular oxygen upstream of the fixed catalyst bed into an input gas stream I which comprises molecular hydrogen and the hydrocarbon to be dehydrogenated and is flowing within the shaft toward the fixed catalyst bed.
