    摘要： The present invention provides novel tertiary alcohol compounds which are useful as monomers for the preparation of photoresist materials having high transparency and a great affinity for the substrate and hence suitable for use in photolithography using a light source comprising preferably light having a wavelength of 300 nm or less and more preferably light emitted from an ArF excimer laser. Specifically, the present invention provides tertiary alcohols compounds represented by the following general formula (1): wherein R1 and R2 each independently represent a straigh-chain, branched or cyclic alkyl group having 1 to 10 carbon atoms, in which some or all of the hydrogen atoms on the constituent carbon atoms may be replaced by a halogen atom or halogen atoms, or R1 and R2 may be joined together to form an aliphatic hydrocarbon ring; Z represents a straight-chain, branched or cyclic divalent organic group having 2 to 10 carbon atoms; and k is 0 or 1.

    摘要： The method of the invention uses raw corn, or a corn by-product as a source. The source is mixed with an alcohol to produce an alcohol-corn slurry. Centrifugation or filtration produces a clear filtrate from the alcohol-corn slurry. A membrane filtration step is then used to separate purified xanthophylls. Other steps may be combined with the basic process to produce additional corn products, such as oil and zein.

    摘要： An improved method for the recovery of xanthophylls from corn gluten is provided. More specifically, a method for the recovery of xanthophylls from corn gluten whereby relatively dry corn gluten is extracted with an organic alcohol followed by a saponification reaction to convert xanthophyll esters to xanthophylls is described. Using this method, xanthophylls can be recovered from corn gluten in higher yields, greater efficiencies, and higher purity as to compared to prior art methods. Moreover, the xanthophyll product recovered in this method is a crystalline, powdery solid ideally suited for use in food products and pharmaceuticals. This material is especially suited for use in poultry feeds to provide the desired, healthy yellow color or hue in broiler and egg yolks.
