Title: Improvements in or relating to the extraction of sugar from dates
IPC: C13B10/00
Filed: 1948-09-01
Abstract: 660,590. Extracting sugar. A.P.V. CO., Ltd., GREGORY, S. A., BICKLE, R. S., and TINSEY, G. S. Aug. 22, 1949 [Sept. 1, 1948], No. 23033/48. Classes 81 (i) and 127. Sugar is extracted from dates by feeding them through a hopper 15 into the lower end of an inclined elongated container 11 up which they are moved by a moving mechanical conveyer 13 and down which water, heated by injected steam to 90-97‹ C. to soften the dates, is continuously fed and the sugar liquor is removed from the lower end of the container. In the container below the hopper a baffle wall 17 is provided beneath which the liquor in the container rises and overflows over the wall of the container which forms a weir 18, Fig. 4, over which the liquor flows into a wort container 19 with outlet 20 and which controls the level of the liquor in the container. This liquor level is maintained helow the upper end of the conveyer so that the dates are lifted out and can be washed by hot or cold water spray 35. The liquid from outlet 20 is fed to a stone removal machine and then to a reservoir from which it passes to filter presses and thence to fermentation vessel. From the upper end of the machine the removed dates are fed to stone removal machines and the pulp from the latter is fed to filter presses. The liquor from the latter may be returned to the extracting container at the point 59 above the liquor level and/or through inlet 60 below the liquor level. Specification 660,573 is referred to.

Inventor: JONES WILLIAM OWEN
IPC: C07C69/157
Filed: 1953-08-21
Abstract: 2-Cyclooctyl phenyl acetate is claimed as a new compound.  It is prepared by acetylating 2-cyclooctyl phenol, which may be obtained by reacting cyclooctene with phenol in the presence of boron trifluoride-acetic acid as catalyst.  In an example, cyclooctene is reacted with phenol and a boron trifluoride-acetic acid complex as catalyst at 60 DEG  C. to give a mixture of 2- and 4-cyclooctyl phenols and 2:4-dicyclooctyl phenol.  This mixture is treated with caustic soda solution to form and precipitate the sodium 4-cyclooctyl phenate only, which is separated off.  The oil which separates from the resulting liquid as an organic phase is distilled to give 2-cyclooctyl phenol which is then reacted with pyridine, concentrated sulphuric acid and acetic anhydride at room temperature, the reaction mixture treated with dilute hydrochloric acid and the product isolated by extraction and distillation to give 2-cyclooctyl phenyl acetate.

Abstract: 282,863. Imray, O. Y.. (I. G. Farbenindustrie Akt.-Ges.). Sept. 25, 1926. Isatin-a-derivatives; indigo and indigoid dyes. -New water-soluble isatin-a-derivatives are produced by the action of sulphites upon isatin-achloride or its substitution products: the same compounds together with a corresponding amount of an indigo, can be obtained by treating dehydroindigo bisulphites with weakly alkaline agents such as sodium carbonate, alkali sulphite, borax, or very dilute caustic alkali; the solutions of dehydroindigo sulphites obtained from dehydroindigo acetates and sulphites may be directly employed. The new products eontain two sulphur atoms and differ from the known bisulphite addition products in that they are stable to dilute hot acids; with concentrated mineral acids they yield chiefly the corresponding indigo, and with strong alkalis solutions of the corresponding isatins; they are decomposed when spread upon a support, such as paper, and exposed to light. They can be condensed in aqueous solution with the usual components such as naphthol, oxythionaphthene, indoxyl, or acenaphthenone, to produce indigoid dyes. According to examples,. (1) 5-chlorisatin-a-chloride is warmed with sodium sulphite solution and the product salted out; it yields chlorisatin with hot alkali, dichlorindigo by action of hot sulphuric or hydrochloric acid, leuco dichlorindigo with alkaline hydrosulphite, and 2-naphthalene-2-chlorindol-indigo bv condensation with a-naphthol; dibromisatin-a-chloride yields chlorisatin with hot alkali, dichlorindigo bisulphite and tetrabromdehydrindigo bisulphite are warmed with sodium carbonate solution and sodium sulphite solution respectively; the soluble products are salted out after filtering off the indigo or tetrabromindigo simultaneously produced.
