Title: An improved process for the production of the condensation products of phenols with aldehydes
IPC: C08G8/28
Filed: 1927-02-01
Abstract: 283,002. Petroff, G. Feb. 1, 1927. Phenol-aldehyde condensation products.-The formation of the initial condensation products of phenols and aldehydes is effected in the presence of the sodium salt of toluene p-sulphonchloramide. The products may be hardened by heating, with or without the addition of acid or basic catalysts. Suitable acid catalysts are solutions of an acid in an alcohol, such as amyl or propyl alcohol, glycerol, or glycol, in a chlor-substituted hydrocarbon, such as tetrachlorethane, or in a fatty acid. and suitable basic catalysts are alcoholic solutions of glycerates and phenolates. In an example, commercial carbolic acid, formaldehyde, and the sodium salt of toluene p-sulphonchloramide are heated under reflux, whereafter water is evaporated from the product. A solution of octohydroanthracene sulphonic acid in a mixture of ethyl alcohol and glycerine is then added, and the mass is allowed to stand and finally heated. Alternatively, there may be added to the initial product a basic catalyst prepared by adding glycerol to a saturated solution of caustic soda in ethyl alcohol and distilling off part of the alcohol. The sodium salt of toluene p-sulphonchloramide also may be used as a basic catalyst.

Abstract: 284,678. Hulin, P. L. Feb. 3, 1927, [Convention date]. Electrolytic furnaces.-In a furnace for the electrolysis of chlorides or other compounds of light metals such as magnesium, calcium and glucinium, the cathode comprises a number of suspended rods which are cooled at their upper ends The cathodes shown consist of rods D secured co a water-cooled ring E of copper, iron or steel, which mav be made in sections. A cathode with a solid copper ring E is also described. Fig. 6 shows rods which may be adjusted to maintain the distance between the anode and cathode constant as the anode wears away. The cooling effect results in the formation of a light crust on the surface of the bath around the rods, and lessens the action of the chlorine on the rods. The globules of magnesium leave the rods below the surface of the bath, the action of the chlorine on the metal being reduced thereby. A cathode rod may consist of an iron sheet closed at the bottom and containing a core of copper alloy extending beyond the upper end of the sheath.
