摘要： Unsaturated organic compounds, in particular .alpha.-acids and .beta.-acids, are purified prior to hydrogenation by mixing them with an adsorbent capable of adsorbing catalyst poisons, preferably activated carbon, and separating the adsorbent containing the catalyst poisons to recover the thus purified unsaturated organic compounds. A significant reduction in the use of hydrogenation catalyst is realized.

摘要： Tetrahydroiso-.alpha.-acids are prepared from iso-.alpha.-acids metal salts by hydrogenating the salts in a reaction solvent of a lower alkanol containing about 5% to about 20% w/w water and in the presence of up to about 5-50 psig hydrogen and a hydrogenation catalyst at about 30.degree.-50.degree. C. to form tetrahydroiso-.alpha.-acids.

摘要： Disclosed are methods for the production of light stable hop products, useful for the brewing of beer or ale to be stored in clear or green glass containers, which beer or ale will not develop objectionable flavor as a result of exposure to light. Light stable hop products are prepared by double extraction of liquid/supercritical CO2 extracted hop solids with ethanol to remove alpha/iso-alpha-acids. Such alpha/iso-alpha-acids may be further removed from the ethanol extraction filtrate obtained in the double extraction process by subjecting such filtrate to an ion exchange medium, or precipitation by a metal ion, heavy metal ion, or alkali metal ion, or hydrogenation to provide an alpha/iso-alpha-acids free filtrate which may be added to the light stable double extracted hop solid residues obtained in the initial double extraction process.

摘要： Carbon dioxide is used as a reaction solvent in the hydrogenation of organic compounds. The carbon dioxide is preferably a liquid or a supercritical fluid. The hydrogenation method can be used advantageously in methods for making tetrahydroiso-alpha-acids from alpha-acids, iso-alpha-acids, or beta-acids. If beta-acids are used to make tetrahydroiso-alpha-acids, an acidic lower alcohol is preferably added to the carbon dioxide reaction medium to act as a promoter.
摘要翻译： 在有机化合物的氢化中使用二氧化碳作为反应溶剂。 二氧化碳优选为液体或超临界流体。 氢化方法可有利地用于从α-酸，异-α-酸或β-酸制备四氢异α-酸的方法。 如果使用β-酸制备四氢异α-酸，则优选将酸性低级醇加入到二氧化碳反应介质中以起促进剂的作用。
