Title: Heat sealing sheet wrapping materials and coatings therefor
IPC: C09J7/35
Filed: 1951-10-08
Abstract: A coating composition, suitable for applying to flexible organic sheet material to form heat-sealing wrapping material, comprises a cellulose derivative as film-forming substance, a plasticizer therefor, a heat-sealing or blending resin, and a polyorganosiloxane resin comprising molecular chains formed by recurring groups of the formula <FORM:0709575/IV (a)/1> wherein R is an alkyl, aryl, cycloalkyl, aralkyl, alkaryl or alkoxy group.  Moisture-proof coatings on transparent non-fibrous sheet wrapping materials may be obtained and these are age-resistant, heat-sealable, and do not adhere to hot surfaces such as are employed in sealing devices in automatic packaging machines.  Sheet materials which may be coated include films of regenerated cellulose, cellulose esters and cellulose ethers, and fibrous sheet materials such as paper.  When a moisture-proof coating is desired it is preferred to include a wax in the composition.  The polyorgano-siloxane may be dimethyl, dipropyl, dihexyl, diphenyl, phenyl methyl, dinaphthyl, di-amyl-phenyl, di-phenyl-propyl, di-tertiary-butoxy, di-phenylmethoxy, iso-butyl methyl or ethyl phenylmethoxy polysiloxane.  A copolymer such as dimethyl diphenyl polysiloxane may be used.  Cellulose acetate or nitrate or ethyl cellulose may be used as film-former.  In an example a mixture of cellulose nitrates of different viscosities is used.  As heat-sealing plasticizer there may be used dibutyl sebacate, dibutyl phthalate, the propionic ester of b -hydroxy-ethyl phthalimide, or ethyl o-benzoyl benzoate.  The heat-sealing or blending resin may be an alkyd resin, polyvinyl chloride, vinyl chloride-acetate copolymer, a modified rosin resin such as glycerine-modified rosin, a glycerine ester of hydrogenated rosin, copal resin or ester gum.  Rape seed oil and abietic acid are also specified as blending agents.  Paraffin wax may be incorporated with the composition to improve the moisture proofing properties of the coating.  The polyorganosiloxane resin is preferably present only in a small proportion, e.g. 0.1-2 per cent. by weight of the total solids in the composition.  Volatile solvents and diluents are incorporated in the composition to produce a solution of the required concentration.  For sealing the sheet wrapping material there may be used platens which have a coating of a heat-hardenable polyorganosiloxane resin of the same kind as that which is present in the coating on the wrapping material, or a mixture of such resin with metal powder, or the platens may be moulded from a mixture of a polyorganosiloxane resin and metal powder.
Patent GB-684958-A (GB)
Title: Improvements in and relating to the production of oxygen-containing organic compounds
IPC: C07C27/22
Filed: 1949-09-12
Abstract: Oxygen - containing compounds, especially aldehydes, are made from alkene mixtures containing di- and/or poly-enes which may be aliphatic or alicyclic by removing from the mixture the di- and/or poly-enes and then carbonylating at elevated temperature and pressure with a mixture of CO and H2 in which the molar ratio CO : H2 is at least 1 : 4 and preferably at least 1 : 3 in the presence as catalyst of cobalt metal in the form of a suspension or of a soluble cobalt compound dissolved in the liquid, the proportion calculated as metal being preferably at least 0.1 per cent by weight of the liquid. C4-C18 monoolefines are mentioned, especially C4-C12 monoolefines, and particularly C6-C8 normal olefines, especially alpha-olefines and olefines made by thermally cracking higher hydrocarbons, e.g. paraffin wax.  Di- and polyenes have higher densities and refractive indices than the corresponding mono-olefines and they may be removed by fractional, azeotropic and extractive distillation, solvent extraction with aqueous cuprous salts, e.g. cuprous chloride, polymerization and relative hydrogenation.  Conventional carbonylation conditions are used the cobalt preferably being introduced as a soluble organic acid salt.  The aldehydic product may be converted to the corresponding alcohol by hydrogenation.  It is stated that the di- and/or poly-enes inhibit carbonylation.  When selective hydrogenation is used for their removal it is convenient to employ vapour phase reaction over, e.g. copper-on-chromia catalyst, which is optionally supported, e.g. on silica.  Reaction conditions are pressures up to 250 p.s.i., temperatures of 180-280 DEG  C., space velocities of 200-2000 litres/litre of bulk catalyst volume per hour, and a molar ratio of H2 to diene or polyene of 1 : 1 to 5 : 1. Polymerization may be effected by passing the alkene in the vapour phase over aqueous phosphoric acid on metallurgical coke at up to 100 p.s.i. and at 150-250 DEG  C. for contact times of 10-500 seconds, or by treatment with sulphuric acid, e.g. mixed alpha-olefines may be treated with 0.5 per cent by weight of H2SO4 of about 98 per cent strength and after washing the product is distilled to remove the polymerisate. Illustrations are provided of the removal by fractional distillation and polymerization and in an example a C6-C8 cut from the cracking of paraffin wax is fractionally distilled to remove material of high density and refractive index before being carbonylated.
