Abstract: 548,967. Isothiouronium compounds; waterproofing fabrics. DU PONT DE NEMOURS & CO., E. I. Feb. 24, 1941, No. 2477. Convention date, Feb. 24, 1940. [Classes 2 (iii) and 15 (ii)] [Also in Group VIII] Compounds having the formula Z(N(CH 2 X) YR) 2  where R is an aliphatic or alicyclic radical containing at least 7 carbon atoms, Y is the group CO or OCO, Z is a divalent hydrocarbon radical and X is halogen, are reacted with thiourea to form isothiuronium salts, which are used in the treatment of cotton, wool, rayon, nylon and other textiles. They impart a soft feel to the latter and also, after drying and baking, render textiles resistant to water. The starting materials are made by treating the compounds having the formula Z(NHYR) 2  with hydrogenhalide and paraformaldehyde. The compounds Z(NHYR)  2  may be made by reacting alkyl amides or carbamates with formaldehyde or other aldehyde or by treating diamines with two molecular proportions of aliphatic carboxylchlorides or chlorcarbonicalkyl esters. By warming the products with caustic soda, the thiourea groups are removed, dimercaptans being formed. In examples : (1) methylenedidistearamide is treated with hydrogen chloride and paraformaldehyde and the chlormethyl compound condensed with thiourea; cotton cloth impregnated with an aqueous solution containing the product sodium acetate and formaldehyde, after baking becomes water repellant and crease resisting ; (2) methylenedioctadecylurethane and dioctadecyl-#-phenylenedicarbamate are similarly converted into the chloromethyl compound and condensed with thiourea. The following starting materials are also specified : di (N-chlormethyloleylamido) methane, di (N- chlormethylmyristamido) methane, di (N- brommethyllauramido) methane, dioctadecyl- N:N<SP>1</SP>-di (chlormethyl) ethylenedicarbamate, dioctadecyl-N:N<SP>1</SP>-di (chormethyl) hexamethylenedicarbamate, dioctadecyl-N:N<SP>1</SP>-di (chlormethyl) o-phenylenedicarbamate, dioctadecyl-N:N<SP>1</SP>-di (chlormethyl)-1:5-naphthylenedicarbamate, dioctadecyl- N:N<SP>1</SP> - di (chlormethyl) - 6 - methyl - 1:3-phenylenedicarbamate and the corresponding dibrommethyl and didodecyl, dicetyl and dimontanyl derivatives.

Title: Process for the production of food preparations from potatoes and similar farinaceoustubers
IPC: A23L19/12
Filed: 1943-02-22
Abstract: Crisp ready-to-eat food preparations are made by treating peeled and cut potatoes or similar farinaceous vegetables with steam at a pressure of 1-1.5 atmospheres for about 5 minutes, or boiling water for about 10 minutes, to gelatinise part of the starch and burst some of the starch cells without completely cooking them, mashing, converting at atmospheric pressure and at a temperature below 100 DEG C. into a form suitable for rapid and uniform drying, subjecting them to a short intense baking treatment, e.g., for about 10 minutes at a temperature between 200 DEG  and 220 DEG C., and finally drying at a temperature well below 100 DEG C., e.g., for 15-30 minutes at 50 DEG -60 DEG C., to a low moisture content.  Where the potatoes are cut into large pieces, e.g., halves, the treatment with steam or boiling water may be preceded by a dry heat treatment at a temperature above 200 DEG C., e.g. at 215 DEG C. for about 45 minutes, and this treatment may be assisted by spraying with a very dilute solution, e.g., .02-.05 per cent. of a mineral acid, such as hydrochloric acid, or an organic acid, such as lactic acid.  The mashed material may be formed into rods, p  filaments, tubes, sheets, flakes, or discs as by extrusion, pressing, or rolling or into granules by pressing through a jolted perforated screen.  Flavouring or other ingredients, such as salt, cheese, treacle, meat-extract or spices and aerating agents, such as carbonates, may be incorporated in the mash prior to shaping or the shaped material may be coated with flavouring material. According to the first Provisional Specification, the initial dry heat treatment is effected at about 400 DEG C. for about 45 minutes and the intense baking treatment at 400 DEG -450 DEG C. for a few minutes.

Title: A process for the recovery of antimony trifluoride or hexafluoroantimonic acid from complex compounds of hexafluoroantimonic acid and hydrocarbons
IPC: C01G30/00
Filed: 1965-01-22
Abstract: SbF3 is recovered from complex compounds of hexafluoroantimonic acid with hydrocarbons by decomposing the complex by heating to a temperature between 150 DEG  and 350 DEG  C. with the formation of low molecular weight (C1 to C6) hydrocarbons, HF and a SbF3-containing carbonaceous residue and recovering the SbF3 by solvent extraction, e.g. with a low boiling point (i.e. \sO 100 DEG C.) alcohol and/or ketone, e.g. CH3OH, C2H5OH, C3H7OH, (CH3)2CO, CH3.CO.C2H5 and/or recovering by sublimation and/or distillation. The heating may take place at temperatures that rise continuously or stepwise and may be for 1/4 to 2 hours.  The heating may be in an inert gas that is free from O2 or oxygen-containing compounds, e.g. N2, CH4 and C2H6.  Hexafluoroantimonic acid may be recovered by evaporating any HF present in the complex by heating to 88 DEG  to 100 DEG  C. then heating as above, solvent extracting the SbF3, removing the solvent from the extract phase and converting the recovered SbF3 to SbF3Cl2 using elemental chlorine and converting this into hexafluoroantimonic acid using liquid HF, HCl being eluted. The reactions are performed in corrosion resistant vessels, e.g. Pt, Al or Al/Au, Ni/Mo, Ni/W and Al/Mg alloys or vessels lined with polytri- or polytetra-fluoroethylenes.

Abstract: Glycosides of the general formula: <FORM:0950251/C2/1> wherein R is a nitro-phenyl or cyano-methyl group, and the two alkyl groups in the 5-position are identical with one another and the glycosido alkyl and aralkyl groups are C1-4- alkyl and monocyclic-aryl substituted C1-4-alkyl groups respectively and wherein the asterisks denote that the double bonds radiating from the carbon atoms so marked are appropriate to an alpha-glycoside, in particular methyl 5,5-dimethyl -4-(O methyl) -3- (O p-nitro-phenyloxycarbonyl) -2-(O benzoyl) -L- alphalyxopyranoside, are made by reacting the appropriate alkyl or aralkyl 5, 5-dialkyl -4- (O alkyl) -2- (O acyl) -L- lyxopyranoside with a chloroformic acid ester of the general formula: <FORM:0950251/C2/2> wherein R is a nitro-phenyl or cyano-methyl group, in the presence of a tertiary organic base. The preferred starting materials are methyl 5,5-dimethyl -4- (O methyl) -2- [O (benzoyl or p-methoxy-benzoyl)] -L- lyxopyranoside.  The product may be converted to noviose by reaction with ammonia, hydrolysing the carbamoyl compound and de-etherifying it.  The reactions are: <FORM:0950251/C2/3>  Full details are also given for the preparation of the starting material from D-glucose, which undergoes the following transformations: 1, 2 mono-acetone derivative, tri-benzylate, hydrolyse off acetonyl group and methylate; acid catalysed hydrolysis yields the D-glucofuranose.  This is oxidised to D-gamma gluconolactone; which is reacted with ammonia or methyl or dimethylamine to yield the D-gamma gluconic acid amide. The free hydroxyl group in the 4-position of the latter is esterified with a sulphonic acid; for example, by treatment with methane-sulphonic acid chloride. The next step consists in the solvolysis of the 2-(O alkyl)-3, 5, 6-tri (O benzyl) -D-gluconic acid amide which has been esterified in the 4-position with a sulphonic acid, whereupon a 2-(O-alkyl)-3, 5, 6-tri (O benzyl)-D-gamma-galactonolactone is formed.  By reaction of this lactone with an alkylmagnesium halide by the Grignard method (preferably employing one mol of lactone to two mols of organo-metallic compound), followed by hydrolysis of the reaction product, a 1,1-dialkyl-2-(O-alkyl)-3, 5, 6-tri(O-benzyl) -D- galactonohexitol is obtained.  The hydroxyl group in the 4-position of this hexitol is then esterified with benzoic acid or the appropriate alkyl- or alkoxy-substituted benzoic acid, or a functional derivative thereof.  Preferred esterification agents are those which give the benzoyl or p-methoxy-benzoyl group.  The esterification product is then reductively debenzylated and subjected to a glycol splitting reaction (employing, for example, lead tetraacetate in methylene chloride solution), whereupon a 5, 5-dialkyl -4- (O alkyl)2-(O acyl-L-lyxopyranose is formed. The latter is then acetalized with a C1-4-alkyl alcohol (which may contain a monocyclic aryl substituent) to form the required starting materials. The example includes full details of the synthesis of the starting material.
