Abstract: Aminomethyl-chromans are obtained by alkylation of correspondingly substituted amines or by reductive amination of correspondingly substituted aldehydes. The aminomethyl-chromans can be used as active compounds in medicaments, in particular for the treatment of diseases of the central nervous system.

Abstract: The substituted pentaalkylchromans of the general formula: ##STR1## wherein R denotes a lower alkyl group having 1 to 4 C atoms and Hal denotes chlorine, bromine or iodine, are novel intermediates for the preparation of hypolipidaemic pharmaceuticals. A process for their preparation is described in which a trialkylhydroquinone is reacted with a halogenated butenol to give a substituted tetraalkylhydroquinone, which is finally cyclized to the final product.

Abstract: Bathing preparations comprising a soluble aluminum carboxylate exhibit excellent dissolvability into bath water.

Abstract: An FCC reactor achieves greater utilization of the space within the reactor vessel by using a vented riser arrangement having an inlet opening at the bottom of a vented riser collector. The inlet opening at the bottom of the vented riser collector allows plug flow of the catalyst and hydrocarbon vapors through the upper and lower section of the reactor vessel without any substantial degradation and separation efficiency between the catalyst and the hydrocarbon vapors. This permits almost the entire tangent length of the reactor vessel to be used for the purpose of catalyst and hydrocarbon contact.

Abstract: Acyclic terpene compounds useful as intermediates for producing sarcophytol A which have an anti-carcinogenic promotor activity and anti-tumor activity, which compounds are shown by the general formula (I): ##STR1##
