Abstract

289,415. Auer, L. April 26, 1927, [Convention date]. Modified fats and oils; candles.-In the treatment of substances containing unsaturated carbon compounds such as mineral or fatty oils, and particularly substances consisting of or containing high-molecular organic acids or their derivatives, with electrolytes to modify their physical properties and produce thermoplastic materials, a solution or colloidal solution of the electrolyte in an organic solvent is employed and the electrolytes consist of organic or inorganic acids, their salts or esters, metallic derivatives of organic compounds, metal oxides or hydroxides, or organic bases. The substance treated may be dissolved in an organic solvent or the treatment be effected in the presence of such a solvent. From the product the solvent may be removed as by centrifuging, distilling, or washing, and excess of the electrolyte by washing. A sulphurizing treatment with for instance sulphur or sulphur chloride, may be effected simultaneously with, or may follow, the electrolyte treatment, and accelerators such as hexamethylenetramine, aniline, or diphenylguanidine may be added. The products may be emulsified in an aqueous medium, preferably in the presence of an emulsifying agent such as ammonium linoleate, soaps, sulphonated fattyacid salts or compounds of organic bases, and in presence or absence of protective colloids. Varnishes, linoleums, rubbers, and soaps may be prepared from the products, with the addition, if necessary, of filling materials, pigments, or solvents. In examples :-Chinese wood oil is treated with a solution of sodium in amyl alcohol, and the excess of alcohol distilled off. The jellylike product is mixed with iron oxide and sulphur and heated at 160‹ C., and finally pressed in moulds. Chinese wood oil and ether are treated with a mixture of stannic tetraphenyl and alcohol, the solvent distilled off, and the product emulsified in water with the assistance of the reaction product of a fatty oil and sodium cresylate. The emulsion can be used with rubber latex as a rubber substitute. Specifications 14281/10, [Class 2 (iii), Dyes &c.], 153,942, 259,431; 261,406, [Class 2 (iii), Dyes &c.], and 287,943 are referred to. The Specification as open to inspection under Sect. 91 (3) (a) refers also to the treatment of goudrous, to the use of sulphonated fatty acids, organic bases, albuminous compounds, sulphonated alkylated aromatic hydrocarbons, and saponin as emulsifying-agents, and to the employment of the products in the manufacture of candles Hungarian Specifications 3083/26, 3088/26, 3109/26, and 3145/26 are also referred to. This subject-matter does not appear in the Specification as accepted.
