IPC: C09K23/00
Filed: 1930-12-18
Abstract: Emulsions of lecithin with or without added oils are prepared solely with the aid of benzyl alcohol, glycol or the higher homologues derivatives or substitution products thereof such as propylene or amylene glycol, tolyl or phenylpropyl alcohol, glycol ethyl ether, glycolchlorhydrin, pinacone.  The products may be used in oiling leather, treating textiles or in the preparation of baked goods or margarine.  Examples of the invention are as follow: (1) 30 parts of soya bean lecithin containing 30 per cent of oil are mixed with 10 parts of benzyl alcohol, 60 parts of linseed oil are added and the mixture emulsified with 400 parts of water; the product may be used for softening, dressing, or finishing fibres, threads or fabrics, (2) 30 parts of lecithin as in (1) are mixed with 8 parts of benzyl alcohol and 58 parts of neutralized train oil, and emulsified with 900 parts of water, (3) 90 parts of lecithin as in (1) are mixed with 10 parts of benzyl alcohol; the mixture may be dispersed in a fat emulsion constituting margarine or in a dough prepared from meal and water.  Specification 266,746, [Class 91, Oils &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of other alcohols or derivatives or substitution products thereof and states that the emulsion of Example 2 contains 4 parts of triethanolamine.  This subject-matter does not appear in the Specification as accepted.ALSO:Emulsions of lecithin, with or without added oils, suitable for addition to margarine, are prepared solely with the aid of benzyl alcohol, glycol or the higher homologues derivatives or substitution products thereof such as propylene or amylene glycol, tolyl or phenyl propyl alcohol, glycol ethyl ether, glycolchlorhydrin, pinacone.  An example of the invention is as follows 90 parts of lecithin containing 30 per cent of oil are mixed with 10 parts of benzyl alcohol and the mixture dispersed in a fat emulsion constituting margarine.  Specification 266,746, [Class 91, Oils &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of other alcohols or derivatives or substitution products thereof.  This subject-matter does not appear in the Specification as accepted.ALSO:Dressing and finishing agents for fibres, threads, or fabrics comprise emulsions of lecithin, with or without added oils, prepared solely with the aid of benzyl alcohol, glycol or the higher homologues, derivatives or substitution products thereof such as propylene or amylene glycol, tolyl or phenyl propyl alcohol, glycol ethyl ether, glycolchlorhydrin pinacone.  An example of the invention is as follows: 30 parts of soya bean lecithin containing 30 per cent of oil are mixed with 10 parts of benzyl alcohol, 60 parts of linseed oil are added and the mixture emulsified with 400 parts of water.

For example, 90 parts of lecithin, containing 30 per cent of oil, are mixed with 10 parts of benzyl alcohol and the mixture dispersed in a dough prepared from meal and water.  Specification 266,746, [Class 81 (i), Disinfecting &c.], is referred to.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the use of other alcohols or derivatives or substitution products thereof.
