Abstract: A serum albumin fraction is prepared in high yield and purity from plasma and other albumin-containing blood protein fractions by contacting with a resinous polymeric material having a high capacity for adsorption of albumin, heating at 65.degree. C-72.degree. C for about 1-4 hours while maintaining a pH of 5.0-5.5, and then selectively eluting the albumin from the resin-protein mixture at a pH of 3.5-4.5. The resinous polymeric materials are water-insoluble, cross-linked polyelectrolyte copolymers of ethylene and maleic anhydride containing pendant dimethylaminopropyl functional groups.

Abstract: A photochemical reaction system is provided in which a single polychromatic light source is used to simultaneously irradiate a plurality of photochemical reactions with different regions of the spectrum. In this system, the reactions are carried out in separate but adjacent chambers which are accessible to a single polychromatic light source and positioned in series so that each reaction provides a filter for the next adjacent reaction more remote from the light source.

Abstract: The invention concerns dehydrogenation of carboxylic acids, lactones, esters, nitriles, the carbon skeleton of the feed material being characterized as containing mono-unsaturation or alternatively functional groups such as hydroxyl which convert under process conditions to unsaturation, the dehydrogenation reaction being conducted in the presence of a contact catalyst comprising a carbonaceous layer effective for the dehydrogenation of mono-unsaturated reactants to di-unsaturated products. Another aspect of the invention involves production of the mono-unsaturated reactants. In particular, the invention provides a route to sorbic acid, for example by dehydrogenation of hexenoic acids or esters thereof.
