Title: Improvements in the disintegration of vegetable fibrous materials
IPC: D21C3/16
Filed: 1937-04-12
Abstract: A process for disintegrating vegetable fibrous material such as wood, straw or grasses by means of nitric acid consists in impregnating the cellulose material in a pressure vessel with a solution of nitric acid of 10-15 per cent strength by volume under vacuum, then introducing air to provide an excess pressure of several, e.g. 5 atmospheres, or allowing an excess pressure to build up and raising the temperature gradually, e.g. during 3 hours, from its initial value of 30-40 DEG  C. to 40-50 DEG  C., and then displacing the surplus acid by hot water, e.g. at 80-85 DEG  C. and completing the disintegration during 6-8 hours at 70-90 DEG  C. at ordinary pressure if a medium or highly viscous pulp is required, or at raised pressure, e.g. 1-2 atmos. for a pulp of low viscosity.  The excess pressure produced or obtained during the first nitric acid treatment is maintained substantially constant at about 5 atmospheres by blowing off carbon dioxide produced.  The acid removed after the initial impregnation may be made up to strength and re-used. Specification 468,388 is referred to.

Title: Improvements relating to fermented cereal products
Inventor: HEINRICH RICHARD MAX
IPC: C12G3/02
Filed: 1967-03-08
Abstract: In a brewing process in which a mash containing one or more cereal ingredients is subjected to fermentation, one or more of the cereal ingredients including the husk of the cereal is comminuted to such an extent that the husk component becomes sufficiently fine so as to be rendered unobjectionable if retained in the final brew and the comminuted material is subjected to brewing, there being no straining step of the mash or brew included in the entire process from the preparation of the mash until the brew is ready for use.  The comminuting is achieved by grinding the cereal in an air stream pulverizer.  In the making of African beer, both whole maize (or millet) and malt are comminuted, the ground cereal is cooked with water and under pressure, a predetermined pH being maintained by a regulated addition of lactic acid, the comminuted cooked cereal and malt are brought together to effect saccharification, and the saccharified mash is pasteurized and then subjected to alcoholic fermentation in a closed vessel with selected, cultivated yeast. Reference is made also to the preparation of mahew by lactic acid fermentation.

Title: Refining alcohols
Inventor: WISE ROBERT H
IPC: D01G15/62
Filed: 1957-04-03
Abstract: Water-immiscible synthetic C4-C15 alcohols, produced by reaction of mixtures containing carbon monoxide and hydrogen, are contacted with an alkali metal (or ammonium) borohydride or an alkaline earth metal borohydride to destroy undesirable impurities.  The process is applicable to alcohols obtained by the Fischer-Tropsch and oxo processes.  The purification may be carried out simultaneously with a distillation whereby the purified alcohol is separated from the crude alcohol feedstock, or may be used as a finishing process to improve the colour and remove colour-forming impurities from the previously distilled alcohol.  The purified alcohols may be used to produce esters of improved colour or alternatively the borohydride may be added to the esterification mixture.  The preferred borohydrides are those of lithium, sodium, potassium, calcium, magnesium and barium. The borohydrides may be used in the form of a dilute aqueous solution.  If used in the solid form they may be mixed with an inert filtering medium such as clay or diatomaceous earth.  A polyvalent metal halide, e.g. the chloride or bromide of calcium, aluminium, gallium, titanium or zirconium, may also be present.  In the examples: (a) crude isooctylalcohol obtained by the oxo process is heated with sodium borohydride; (b) a crude C8 alcohol obtained by the oxo process is treated with (i) sodium borohydride, (ii) lithium borohydride, and (iii) a mixture of calcium chloride and sodium borohydride; (c) octyl alcohol obtained by the oxo process is treated with potassium borohydride; (d) octyl alcohol obtained by the oxo process is treated with sodium borohydride; the purified alcohol is esterified with phthalic acid in the presence of a trace of sulphuric acid; (e) octyl alcohol obtained by reacting carbon monoxide and hydrogen with a heptene fraction in the presence of a cobalt catalyst is treated with sodium borohydride; and (f) octyl alcohol obtained by the oxo process is esterified with phthalic anhydride, using sulphuric acid as catalyst, in the presence of sodium borohydride. In each case the colour of the product is improved.
