Patent GB-418385-A (GB)
Title: A process for the manufacture of para (or 2.5) diketocamphane carboxylic acid and related acids
IPC: C07C49/437
Filed: 1933-04-27
Abstract: p-Diketocamphane carboxylic acid and related acids are obtained when carbon dioxide is introduced into a solution of p-diketocamphane or bromo-p-diketocamphane in an organic solvent in the presence of metallic sodium, potassium or magnesium.  The metal is present in at least one atomic proportion per molecular proportion of the starting material.  The products, of which one appears to be p-(or 2 : 5)-diketocamphane-3 or 6-carboxylic acid, possess therapeutic properties.  According to the example, dry carbon dioxide is passed into a solution of either starting material in xylene, toluene or benzene, to which the metal has been added.  The solution is kept at a temperature of 100--140 DEG  C., if desired under a pressure of 5--10 atmospheres.  Cold water is added, followed by an inorganic acid, and the p - diketocamphane carboxylic acid then extracted therefrom with ether and crystallized from benzene.  From the mother liquor, two further acids of the formula C11H16O4 are isolated by means of their quinine or cinchonine salts.

Title: Pharmaceutical compositions including low molecular weight polypeptides
IPC: C07K14/575
Filed: 1976-03-29
Abstract: The novel polypeptides consist of a sequence of 3 to 10 amino acids which corresponds to a part of the amino acid sequence 265 - 537 of the Fc region of immunoglobulin E (IgE). A first amino acid or a peptide, which may be covalently bonded to a solid carrier, is condensed with a second amino acid or a peptide so that the total number of the amino acid radicals is equal to that of the polypeptide to be prepared. Carboxyl and amino groups, except for those which are to react, are present in protected form; the protecting groups and the solid carrier are subsequently cleaved off. The polypeptides are also converted into salts, esters, amides, N-acyl derivatives and O-acyl derivatives. The compounds block the bonding sites of IgE; they can be used for the prophylaxis or treatment of the symptoms of allergic reactions.
Patent GB-582034-A (GB)
Title: Production of alkylated aromatic compounds
IPC: C07C2/66
Filed: 1944-07-03
Abstract: An aromatic compound is alkylated by contacting it with a mixture of an olefin and a paraffin which is of lower solubility in said aromatic compound, separating the absorption product from unabsorbed material and contacting it with an alkylation catalyst under alkylating conditions.  The olefin may also be mixed with hydrogen or other diluents produced in its preparation by dehydrogenation or cracking.  The compound alkylated may be a hydrocarbon, e.g. benzene, toluene or xylene, phenol, cresol, benzyl alcohol, benzoic acid, aceto phenone, or chlorbenzene or nitrobenzene.  The extraction of the olefin with an aromatic hydrocarbon to be alkylated may be made more selective by adding to the latter an agent capable of increasing the solubility of the olefin, e.g. liquid sulphur dioxide, acetone, methyl or ethyl alcohol, b -b -dichlorethyl ether, nitrobenzene, benzonitrile, furfural and methyl formate.  These generally have a higher boiling point than the hydrocarbon to be alkylated to facilitate separation prior to alkylation.  In producing cumene from benzene and propene, gases containing C2-4 hydrocarbons and hydrogen may be utilized by scrubbing in counter current a C3 fraction, with or without lighter gases, with the benzene, and passing the absorption product to an alkylator.  Any propane in the product may be dehydrogenated to propene and added to the feed to the scrubber. About 3-10 mols. of benzene per mol. of propene may be used for the absorption at about 10-40 DEG  C. and 15-35 atm.  The presence of small amounts of C2 and C4 hydrocarbons is permissible, ethyl and butyl benzenes formed in the alkylation optionally being included with the cumene as fuel components.  The alkylation may be effected with liquid catalysts, e.g. sulphuric or phosphoric acid, hydrogen fluoride or solutions or suspensions of aluminium chloride or its complexes, by the method of Specification 540,824, with solid catalysts, especially aluminium chloride or phosphoric acid on a support, as in Specification 579,781, or with gases such as boron fluoride.  The dehydrogenation step may be effected as in Specification 464,957, [Group III].  Prior to the absorption, separation of components such as hydrogen by fractionation or of hydrogen sulphide may be effected.  The Specification as open to inspection under Sect. 91 comprises the use of alkylating agents generally, mixed with less soluble compounds, for example alkyl halides contaminated with hydrocarbons or hydrogen halides. Alcohols, ethers and esters are also specified.  This subject-matter does not appear in the Specification as accepted.

Title: Method for polymerizing ethylene alone or together with other olefinic comonomers and catalyst therefor
IPC: C01B25/37
Filed: 1966-03-24
Abstract: A polymerization catalyst for ethylene alone or admixed with other olefinically unsaturated monomers comprises (1) a vanadium phosphate having a composition expressed by the general formula (V2Oy)(P2O5)z wherein Y represents the mean valence of the vanadium atom and is a number not less than 4 and less than 5, and z is a positive number less than 10, and (2) a compound or composition having a mean formula of RnAlX3- n, wherein R is a hydrocarbon radical of 1 to 8 carbon atoms, X is a halogen atom and n is a number greater than 0 and less than 3. The vanadium phosphate is preferably made by treating pentavalent vanadium phosphate with an organic compound selected from a hydrocarbon, alcohol, aldehyde, or an aldehyde polymer, drying, heating at a temperature ranging from 250 DEG  to 600 DEG  C. to reduce the mean valency of the vanadium atom to between 4 and 5.  The vanadium compound may be supported. Component (2) may be a mixture of an organoaluminium compound and an aluminium halide. The comonomers may be propylene, butene-1, styrene, 3-methylbutene-1, octane-1, or hexadecene-1. A small amount of a linear or cyclic diolefin may be present such as butadiene, isoprene, piperylene, 1,5-hexadiene, cyclo-octadiene, dicyclopentadiene, or vinyl cyclohexene. The polymerization may be effected in bulk but is preferably carried out in a hydrocarbon or halogenated hydrocarbon solvent or diluent. Hydrogen may be present.  The polymers are recovered by conventional "low-pressure" techniques.ALSO:A vanadium phosphate having a composition expressed by the general formula (V2Oy) (P2O5)z wherein y represents the mean valence of the vanadium atom and is a number not less than 4 and less than 5, and z is a positive number less than 10, is made by reducing a penta-valent vanadium phosphate by (1) heating in a current of H2, CO, or SO2, or (2) by heating at about 400 DEG C. in the presence of an organic compound such as benzene, toluene, methanol, ethanol, propanol, butanol, formaldehyde, benzaldehyde, and aldehyde polymers.  The pentavalent vanadium phosphate can be made by reacting a penta-valent vanadium compound with phosphoric acid or a phosphate, e.g. vanadium pentoxide with ortho-phosphoric acid containing a small amount of water, or reacting ammonium vanadate and orthophosphoric acid at room temperature for five days.  In the examples compounds of the above formula are all made by method (2).
