Patent GB-367545-A (GB)
Title: The manufacture of conversion products of higher paraffin hydrocarbons
IPC: C07C17/00
Filed: 1931-02-06
Abstract: The Specification comprises further examples, as below, of the process of the parent Specification for the manufacture of products, which may be used in the textile and leather industries as lubricating and greasing agents, either as such or in emulsified form by the treatment of technical mixtures of higher paraffin hydrocarbons containing more than eight carbon atoms and at least two halogen atoms in the average molecule, with aqueous caustic alkalies or alkali carbonates (bicarbonates being excluded) or alkaline earths: (1) a chlorinated hard paraffin obtained by direct chlorination until the entrance of 3-4 chlorine atoms into the average molecule (367) is heated in an autoclave with 16 per cent caustic soda lye.  The product, which is a mixture of olefine alcohols useful in the textile industry, comprises an oil and a tallowy material: (2) a light product of buttery consistency is similarly obtained by treatment of the same starting material with caustic soda lye of 33 DEG  B<\>ae: or caustic potash lye.  By further heating the product, the chlorine may be entirely removed: (3) a chlorinated soft paraffin obtained by chlorination until the entrance of four chlorine atoms into the average molecule (300) is heated with aqueous sodium or potassium carbonate in an autoclave: (4) a chlorinated product obtained by chlorinating hard paraffin until the entrance of five atoms into the average molecule (367) is heated in an autoclave with water and barium carbonate or milk of lime whereby a viscous oil is produced: (5) a chlorinated product obtained by chlorinating American paraffin until the entrance of seven chlorine atoms into the average molecule (254) is heated in an autoclave with 57 per cent caustic potash lye.ALSO:The Specification comprises further examples, as below, of the process of the parent Specification for the manufacture of products, which may be used in the textile and leather industries, e.g. as lubricating and greasing agents, either as such or in the form of an emulsion by the treatment of technical mixtures of higher paraffin hydrocarbons containing more than eight carbon atoms and at least two halogen atoms in the average molecule, with aqueous caustic alkalis or alkali carbonates (bicarbonates being excluded) or alkaline earths, whereby in some cases products of a more solid consistency are obtained: (1) a chlorinated hard paraffin obtained by direct chlorination until the entrance of 3-4 chlorine atoms into the average molecule (367), is heated in an autoclave with 16 per cent caustic soda lye.
