Patent GB-808124-A (GB)
Title: Process for the production of dicarboxylic acids
IPC: C07C45/50
Filed: 1955-07-27
Abstract: A mixture of b -(3-carboxycyclohexyl) propionic acid and b -(4-carboxycyclohexyl) propionic acid is made by dimerizing butadiene to form 1-vinyl-cyclohexene-3, subjecting the latter to the aldehyde synthesis with carbon monoxide and hydrogen to give a mixture of dialdehydes, catalytically hydrogenating the latter under pressure to give the corresponding diols and oxidizing these to the carboxylic acids.  The dimerization may be effected by known methods without a diluent, or by heating the butadiene to 200 DEG  C. with dodecane in the presence of iron powder in an autoclave, or continuously in a tubular coil.  The aldehyde synthesis may be conducted at 150-160 DEG C. and at a pressure of 250-300 kg./sq. cm. in the presence of an inert liquid diluent such as benzene or toluene, a polymerization inhibitor such as metallic cobalt or iron, and a stabilizing agent such as hydroquinone.  The catalyst may be a cobalt carbonyl hydride or a compound capable of yielding this such as an acidified aqueous solution of magnesium sulphate and cobalt sulphate.  The oily product obtained is heated at 200-220 DEG  C. with water to precipitate the cobalt and cleave any acetals formed.  The hydrogenation may be conducted at 150-155 DEG  C. in the presence of a thorium-free cobalt-magnesia-kieselguhr catalyst at 200 kg./sq. cm.  The product is fractionated to give a mixture of 3-(methylolcyclohexyl) propan-1-ols and cyclohexyl-propanol, the latter being derived from monoaldehyde formed at the previous stage.  The diols are separated by distillation and oxidized with concentrated nitric acid and ammonium vanadate or by heating with a molten alkali, such as potassium hydroxide, in the presence of octadecane with the elimination of hydrogen to form the corresponding salts which are then acidified.  The solid b -(4-carboxycyclohexyl) propionic acid is separated by filtration and the liquid b -(3-carboxycyclohexyl) isomer is obtained from the filtrate by extraction.  Examples are given. Specifications 728,913 and 750,144 are referred to.

Title: Water-soluble dyestuffs containing sulphuric ester groups
Inventor: ANDREW HERBERT FRANCIS
IPC: C09B47/12
Filed: 1958-07-09
Abstract: The invention comprises water-soluble dyestuffs which contain from one to eight methylene groups each methylene group being linked on the one hand to an aromatic nucleus and on the other hand through a nitrogen or sulphur atom to a divalent cycloalkylene, alkylene, hydroxyalkylene, sulphatoalkylene or allyloxyalkylene radical carrying a sulphated hydroxyl group, and mixtures of such dyestuffs. The dyestuffs are made by sulphating the corresponding hydroxy compounds, by synthesising the dyestuffs by methods known to be capable of converting colourless dyestuff intermediates into dyestuffs, the said intermediates together containing from one to eight of the above-defined methylene groups attached to an aromatic nucleus, or by condensing coloured sulphonyl chlorides with amines containing such methylene groups attached to an aromatic ring.  The dyestuffs may be of the anthraquinone or other polycyclic quinone, azo, azoxystilbene, acridine, thiazine, azine, di- and tri-arylmethane, indigoid, peridicarboxylic imide, nitro or phthalocyanine series. The dyestuffs colour in a variety of shades protein fibres, synthetic fibres such as nylon and polyacrylonitrile fibres by the usual methods, or colour natural or regenerated cellulose fibres in conjunction with an alkali treatment.

Title: Improvements in or relating to the manufacture of cellulosic products
IPC: C08B1/02
Filed: 1924-09-25
Abstract: 249,173. Dreyfus, H. Sept. 25, 1924. Pulp, preparation of.-A high quality cellulose is prepared by pretreatment of cellulosic materials first with acetic alkali or other basic purifying materials and then with glacial or dilute acetic, formic or other lower fatty acid. The process is particularly applicable to sulphite pulp, soda pulp, sulphate pulp and other pulps which have been treated for the removal of the lignocelluloses, pentosans, resins, &c., particularly those in which this extraction has been carried out with low pressure or with open boil, such pulps being prepared from wood. bamboo, reeds, esparto and other grasses; but it may be applied to mechanical wood pulps, in which case these are first treated for the removal of the lignocelluloses &c. or this extraction may be combined with the treatment with alkali constituting the first stage of the present process; and cotton may also be treated. The caustic alkali is preferably used in concentrations of less than 3 per cent, preferably of “-2 per cent, in which cases the treatment may be applied as a repeated or prolonged treatment in the end or at moderate temperatures or with boiling-it is preferred however to boil for a substantial time; when stronger solutions of caustic alkali say 10- 20 per cent, are employed, the treatment is carried out at lower temperatures, and preferably with the higher concentrations, in the cold; further a treatment with strong caustic alkali solution such as would swell the fibres, may be followed by a treatment with dilute alkali solution. In all cases, mercerization of the cellulose is undesirable and is to be avoided. The caustic alkali solution is used in excess. that is, in the proportion of 10-40 times the weight of the pulp according to the strength of the alkali solution. Mechanical wood pulps require more drastic treatment, that is, they require repeated or continued treatment as by boiling with caustic alkali solution; and if the extraction of the lignocelluloses &c., is to bo combined with the pretreatment then it is necessary to increase the quantity of the alkali employed in order to allow for that consumed in such extraction. In the place of caustic alkali, other basic materials may be employed such as alkali carbonates, barium hydroxide, sodium aluminate or zincate. ammonia, methylamines, or tetrammonium bases, the conditions being adjusted according to the basicity or alkalinity of the agent selected; thus. with weakly alkaline agents it may be necessary to use concentrated solutions and to boil under pressure say of 2-3 atmospheres. It is probably that one effect of the alkali treatment is to secure a more complete removal of the lignocelluloses, pentosans, resins. &c. The second stage of the process treatment with acetic acid. &c., is preferably carried out with glacial acetic acid, although diluted acid may be employed, and it preferably comprises boiling, say for several hours, although lower temperatures or even prolonged treatment in the cold will give satisfactory results.
