Abstract: Disclosed is a process for upgrading paper-grade wood pulp to dissolving grade pulp which is suitable for use in the preparation of viscose rayon, cellulose ethers and cellulose esters such as cellulose acetate. The process utilizes a sequence of caustic extraction, xylanase treatment and caustic extraction to remove most of the xylan, which may be recovered for use in the production of xylose, xylitol, and furans.

Abstract: A method for quantitatively monitoring in situ by Raman spectrometry one or more selected constituents of a chemical composition comprises: simultaneously irradiating with a substantially monochromatic radiation source a reference material and a chemical composition containing one or more constituents, the radiation being transmitted from the source to the chemical composition by an excitation conduit connecting the source to an optical probe that interfaces with the composition; simultaneously acquiring at more than one wavelength convolved Raman spectra of the reference material and the chemical composition by means of a spectrograph, which is connected to the optical probe by a collection conduit; choosing the standard Raman spectrum of the reference material; determining the convolution function of the convolved spectra from the convolved Raman spectrum and the standard Raman spectrum of the reference material; applying the convolution function to adjust the convolved Raman spectrum of the composition to produce the standard Raman spectrum of the chemical composition; and applying predetermined calibration means to the standard Raman spectrum of the chemical composition, by which the chemical constitution of the composition at the time of acquisition of the convolved Raman spectra can be ascertained.

Abstract: This invention provides a catalyst recovery process whereby a liquid/liquid extraction is used to separate mixtures of 2-alkene-1,4-diols and 3-alkene-1,2-diols, formed by the hydration of gamma,delta-epoxyalkenes using mixtures of hydriodic acid and organic solvent soluble iodide salts as catalysts, from the catalyst. In this extraction, gamma,delta-epoxyalkene, or a gamma,delta-epoxyalkene-containing organic solvent, is used to convert any hydriodic acid present to iodoalcohol and to extract the catalysts from water, leaving the diol products in the aqueous phase, from which they may be subsequently recovered by distillation, extraction or by other means.
