Patent GB-1103326-A (GB)
Title: A process for producing hydrocarbon compounds of aluminium
IPC: C07F5/06
Filed: 1965-04-27
Abstract: Internal olefins are made by displacement from internally-linked hydrocarbon compounds of aluminium with an a  olefin, e.g. dodecene and tetradecene, the internal olefin can have 8-18 carbon atoms, e.g. dodecene and tetradecene. The displacement reaction may be at 280-320 DEG  C. with a contact time of 0.1-1 second under parallel flow conditions or at 180-220 DEG  C. with a contact time of 20-60 seconds under countercurrent flow conditions. The internal olefins can be recycled to produce the initial aluminium compound.  Excess a  olefin can be used in the displacement reaction, e.g. a 1 to 5:1 excess.ALSO:Hydrocarbon compounds of aluminium in which the aluminium is linked to the terminal carbon atom are prepared by isomerizing at least 50% of an internally linked hydrocarbon compound of aluminium and thereafter displacing any remaining internally linked groups by reaction with an a -olefin.  The critical compound may be formed by displacing the organo groups of an organo aluminium with an internal olefin.  The internally linked groups may contain 8-18 C atoms each, and may be of equal size. The a  olefin may contain the same number of C atoms as the displaced group, e.g. dodecene.  The displacement reaction with internal olefin may be at 150-300 DEG  C. with a contact time of 0.1-300 seconds.  The displacement reaction with the a  olefin may be at 280-320 DEG  C. with a contact time of 0.1 to 1 second in a parallel flow reactor, or at 180 DEG  to 220 DEG  C. with a contact time of 20-60 seconds in a counter-current flow reactor. The internal olefins displaced by the a  olefin may be recycled. Primary alcohols and acids may be formed from the hydrocarbon compounds of aluminium. The organo aluminium may be triisobutyl aluminium. The internal olefin may be dodec-3-ene.  The isomerization may be up to 97% primary alkyl content.  Purities of the primary alkyl aluminiums may be up to 99.7%.  Any internal olefins remaining after displacement and isomerization are preferably flashed off and recycled before the second displacement. Any unreacted a  olefin and internal olefin in the effluent after the second displacement reaction is preferably recycled.

Patent GB-481185-A (GB)
Title: A process for improving artificial fibrous material
IPC: D01F1/10
Filed: 1936-06-29
Abstract: Artificial fibrous materials are treated with a nitrogenous condensation product obtained by the reaction of an alkyl halide, which contains at least two halogen atoms attached to different carbon atoms, at a raised temperature with ammonia or a compound containing a primary amino-group in such proportions that for every reactive hydrogen atom attached to the nitrogen of the nitrogenous component there are present about one and one-third or more atomic proportions of halogen of the alkyl halide.  In the production of the condensation product, all the reactive hydrogen atoms undergo substitution, and the product contains no organically combined halogen.  The nitrogenous condensation product may be obtained in presence of polymeric compounds or compounds capable of polymerization, e.g. acrylic acid or other vinyl compounds.  The treatment of the fibrous materials with the condensation product imparts greater resistance to creasing, increases the adsorption capacity towards wool dyestuffs, and improves the water-repelling properties.  Treatment may be carried out on the finished artificial fibres or during the course of their production.  In an example, there is added to a spinning bath for viscose artificial silk a small proportion of a product obtained by reaction of ethylene chloride with ammonia under raised pressure at raised temperature, excess ethylene chloride being removed at the end of the reaction, or a product obtained by using octadecylamine or octadecenylamine instead of ammonia.  In another example, there is added to a cuprammonium artificial silk spinning solution or coagulating bath a small proportion of a condensation product obtained by boiling triethylene tetramine with excess of ethylene chloride in presence of caustic soda lye. The product may be emulsified, if desired with the aid of an emulsifying agent, in the spinning solution or bath or in a subsequent treatment bath.  An emulsifying agent may be incorporated during the preparation of the condensation product. In another example, there is added to the spinning solution for producing viscose, cuprammonium, cellulose acetate, or polyvinyl chloride filaments, a reaction product of ammonia, ethylene diamine, or octadecyl or octadecenyl amine, with excess of trichlorinated hard paraffin.  In another example, any one of the products previously specified is incorporated in finely divided, emulsified or colloidal form in an after-treatment bath for artificial spun fibres.

Title: Coke-making process
IPC: C10B57/08
Filed: 1963-05-09
Abstract: In a process for producing coke from a mixture comprising a coal with good coking properties and at least one of the substances, coke breeze, ore or other mineral and coal with poor or no coking properties, the mixture is preheated before being coked in an oven by direct contact with a hot gas, the hot gas first coming into contact with a part of the mixture composed wholly or mainly of substance which is non-coking or has poor coking properties and then into contact with the rest of the mixture.  The hot gas may be a mixture of fresh combustion gas at e.g. 1400 DEG  C. and recirculated gas in amounts depending on the proportion of non-coking or poorly-coking substance in the mixture.  In the event of this proportion being 40% by weight no gas need be recirculated.  The first part of the mixture to be coked may be fed into a stream of the hot gas and the second part of the mixture added thereto or the preheated first part may be separated from the preheating gas before the second part of the mixture is introduced.  In a modification a stream of preheating gas containing the first part of the mixture to be coked is led into a chamber and maintained therein as a fluidized bed, the second part of the mixture being separately introduced into the fluidized bed.  The coking may be effected at between 400 DEG  and 1,000 DEG  C. and in an example the mixture to be coked was preheated to a temperature of 320 DEG  C.
