Abstract: Color-containing alkanolamines or alkyleneamines, having color numbers of up to 100 PtCo or higher, can be treated with inorganic solid acidic catalysts. Inorganic support materials having bonded inorganic acid functionalities may be used as the inorganic solid acidic catalysts. In the presence of water, these inorganic solid acidic catalysts produce decolorized alkanolamines or alkyleneamines having color numbers of 20 PtCo or less. The process of decolorization can be carried out in batch or continuous mode processes thus providing low cost, high quality and high purity end products.

Abstract: Optionally substituted cyclohexylamine and optionally substituted dicyclohexylamine can be obtained by catalytic hydrogenation of optionally substituted aniline, a catalyst being employed which contains ruthenium, palladium or a mixture of both metals, which are applied to a support of niobic acid or tantalic acid or a mixture of both. The catalyst contains the noble metal(s) in a total amount from 0.05 to 5% by weight, relative to the total weight of the catalyst. In the case of the use of both noble metals, their weight ratio to one another is 1:9-9:1.

Abstract: The invention provides a specific measure of iron stores in vivo using magnetic resonance imaging. T.sub.2 relaxation times in both lower-to-mid field strength magnetic resonance imaging instruments and a higher field strength instrument is evaluated. T.sub.2 obtained at the higher field strength instrument is subtracted from T.sub.2 obtained at the lower field strength instrument. This difference, T, is then correlated with a quantitative measure of the iron stores in vivo in the scanned tissue. A two-dimensional or multidimensional map of the scanned tissue is then constructed on the basis of T to visually identify different tissue types as being normal or abnormal, either through a visual determination based on gray scales or a numeric comparison based on quantitative measure. The introduction of artificial or nonbiological substances as opposed to natural ferritin, is permitted for further diagnostic use by application of this methodology.

Abstract: A continuous process for making N,N-dimethylacrylamide (NNDMA) is disclosed which uses a commodity chemical, namely vinyl chloride (VCl), which is amidated with dimethylamine (DMA) and carbon monoxide in the presence of a supported palladium(O) triorganophosphine catalyst used under conditions where the ratio of P/Pd is critical. The continous process unexpectedly provides the catalyst with long life because the reaction can be carried out in a moving bed of catalyst in the presence of enough acetonitrile solvent to prevent deposition of DMA.HCl, formed during the reaction, in the pores of the catalyst support.
