Abstract: Natural and synthetic rubbers, rubber articles, and rubber latices are preserved by incorporating therein an antioxidant of the formula <FORM:0805368/IV (a)/1> in which R1 is an alkyl radical, e.g. methyl, ethyl, n-butyl, or nonyl, and R2 is a secondary alkyl radical (which may be cycloalkyl) of not more than 8 carbon atoms, attached to the aromatic nucleus through the secondary carbon atom.  The antioxidants specified comprise 2-and 3-isopropyl-4-methoxyphenols, 2- and 3-sec. - butyl - 4 - methoxy - phenols, 2- and 3-cyclo - hexyl - 4 - methoxyphenols, and the corresponding 4-ethoxy and 4-butoxy compounds.  When the process of manufacture yields mixtures of 2- and 3-substituted 4-alkoxyphenols these may be separated, or the mixtures themselves used as antioxidants.  If such mixtures contain 10 per cent by weight or less of a dialkylated-alkoxy-phenol this need not be removed.  The synthetic rubber may consist of a polymer of butadiene-1 : 3, isobutene, or 2-chlorobutadiene1 : 3, or a copolymer thereof with acrylonitrile, styrene, methyl methacrylate, or other compound copolymerizable therewith.  In examples are described the preparation of mixtures of 2- and 3-isopropyl-4-methoxyphenols and of 2- and 3 - cyclohexyl - 4 - methoxyphenols, respectively (see Group IV (b)), and the preparation of natural rubber compositions containing such mixtures.ALSO:To prepare a rubber antioxidant having the formula <FORM:0805368/IV (b)/1> in which R1 is an alkyl radical, e.g. methyl, ethyl, n-butyl, or nonyl, and R2 is a secondary alkyl radical (which may be cycloalkyl) of not more than 8 carbon atoms and attached to the aromatic nucleus through the secondary carbon atom, a 4-alkoxy-phenol is reacted with a secondary aliphatic or cycloaliphatic alcohol containing not more than 8 carbon atoms, or the corresponding olefine, in the presence of a Friedel-Crafts catalyst, e.g. sulphuric acid, anhydrous zinc chloride, or boron fluoride or its complexes with ether or phosphoric acid.

Patent GB-727074-A (GB)
Title: Manufacture of monochloroacetic acid
Inventor: JR JOHN TURNER PINKSTON
IPC: C07C51/363
Filed: 1952-10-29
Abstract: Monochloracetic acid of low dichloracetic acid content is obtained by passing chlorine into a mixture of glacial acetic acid with either acetyl chloride or acetic anhydride and sulphuric and/or phosphoric acid or the sulphate, phosphate, nitrate, acetate or chloride or manganese, chromium, calcium, cobalt, nickel, sodium, zinc, barium, potassium, lithium, caesium, magnesium, vanadium, copper, silver, cadmium or tin.  These acids and salts ionize in glacial acetic acid and inhibit the formation of dichloracetic acid by decomposing the peroxides simultaneously produced during the reaction.  Chlorination should not be carried beyond 85 per cent and excess acetic acid, by-product ahydrides and the acetyl chloride in the reaction mixture are removed by distillation at ordinary pressure, preferably passing hydrogen chloride in countercurrent through the products in a packed tower at a temperature above the boiling-point of acetyl chloride before fractionation of the monochloracetic acid at reduced pressure. In examples, chlorine is passed into a reactor equipped with a reflux condenser, an agitator and gas distributer, containing glacial acetic acid, acetic anhydride and the compound which decomposes peroxides. Acetic anhydride is added periodically and acetyl chloride finally removed from the products by passing in recovered hydrogen chloride. The remaining mixture is then distilled to free it from the compound which decomposes peroxides and the distillate again distilled under reduced pressure.  In a modification, the acetyl chloride and excess acetic acid are removed as a first fraction and the mono- and di-chloracetic acids as a second fraction from the crude product by fractional distillation under vacuum in a column packed with glass helices.  A flow sheet is given in which the excess acetic acid, by-products and recovered materials are recycled.

Title: Method of texturizing soft uncured cheese
Inventor: HURLBURT JOHN CONRAD
IPC: A23C19/076
Filed: 1962-07-16
Abstract: Soft uncured cheese such as cream cheese or Neufchatel cheese, is texturised by uniformly dispersing in the cheese rendered flowable a concentration of inert gas for the cheese in excess of that required to saturate the cheese so as to open the texture of the cheese, and thereafter packaging the cheese.  The inert gas is dispersed in the cheese under a gauge pressure of at least fifty pounds per square inch in sufficient concentration to provide a total volume of the cheese of between 1% and 5% greater than the total volume before the introduction of inert gas, the relative volumes being measured at atmospheric pressure, and the gas is maintained in dispersion under pressure during the subsequent packaging of the cheese which preferably takes place at elevated temperatures prior to cooling; if the dispersion is subjected to substantial working prior to packaging as by straining through a 30 mesh screen, pressures of 70 pounds per square inch (even up to 1000 pounds per square inch) may have to be imposed.  The cheese may be rendered flowable either by heating, usually to a temperature within the range 135 DEG -180 DEG F., or by beating or whipping.  Inert gases mentioned are nitrogen, helium, argon, krypton and zenon.  It is stated that the texturised cheese has an extended shelf life (up to 4 weeks or more).  Examples are given.
