Title: Improvements in and relating to the manufacture of aromatic oxyaldehydes
IPC: C07C47/56
Filed: 1929-05-18
Abstract: 333,313. Riedel-E. de HaÙn Akt.- Ges., J. D. May 18, 1929. Addition to 285,451 and 290,649. Vanillin; pyrocatecheuic aldchyde.-The mixture of alkoxyvanillin and 4-alkoxymethyl ether of 1-propenyl-3 : 4-pyrocatechin obtained by the alkaline oxidation with nitro compounds of the alkaline decomposition products of safrol, is separated by fractional acidification. The unoxidized propenyl compound, which is precipitated first, is alkylated, treated with dilute acids to remove the alkoxymethyl group and the resulting iseugenol or homologue oxidized to vanillin or its higher homologues. The alkoxyvanillin, after protection of the free hydroxy group, e.g. by acidylation, is treated first with dilute acids and then with alkylating agents so as to obtain vanillin or its homologues, the acidyl or other group being removed by saponification. Alternatively, the alkoxyvanillin is converted into protocatecheuic aldehyde by treatment with dilute acids. In one example, the oxidized products derived from safrol as described in Example 2 of Specification 290,649 are separated by addition of acetic acid. The 4-methoxymethylether of 1-propenyl-3 : 4- pyrocatechin dissolved in alcoholic caustic soda is treated with ethyl chloride and the ethylated product saponified with dilute acid in accordance with Specification 284,199 to obtain 1-propenyl- 3 : 4-pyrocatechin-3-ethylether. The latter is oxidized to the corresponding aldehyde by means of nitrobenzene. The methoxyvanillin separated by further addition of acetic acid is converted to protocatecheuic aldehyde by boiling a methyl alcoholic solution thereof with mineral acid. In a second example, the methoxyvanillin is treated with benzenesulphonyl chloride to protect the hydroxy group, and the methoxymethyl group removed by boiling with a little hydrochloric acid in methyl alcoholic solution. After methylation with dimethylsulphate the resulting benzene sulphonic ester of vanillin is saponified with alcoholic caustic soda to give vanillin. Specifications 285,551 and 318,939 also are referred to.

Title: Improvements in flushing cisterns for sanitary and other purposes
IPC: E03D1/08
Filed: 1930-05-28
Abstract: 355,749. Siphon - discharge waterwaste preventers. CLEVELAND, F. J., 29, Southampton Buildings, London.- (Nicholl, G.; 26, Park Road, Walmer Estate, Cape Town, South Africa.) May 28, 1930, No. 16527. [Class 26.] A flushing cistern of the siphon-discharge type for sanitary or other purposes contains a central tube D extending from the outlet B to above the water level, and surrounded by a sleeve or guide pipe N, having attached to it a lift base O to which the lifting rod Q is secured. An annular ring R normally rests on the base 0, and is loose on the rod Q but is prevented from rising by a stop Q<1>. The rod passes through a hole T, which is sealed by water in a cup-shaped container V, and is operated by a horizontal rod X, quadrant Y and chain AA, a stop CC, by coming to rest against the side of the casing, retaining the quadrant in the desired position. The water level in the container A is maintained, by the usual floating ball valve, just below the open end E of the tube D, and when the rod Q is lifted, the water is raised bodily by the lift base and annular ring until it overflows down the tube D. The stop Q<1> eventually strikes the under portion of the casing, and the rush of water causes the ring R to rise and allow water to flow freely around the lift base until most of the water in the container has been siphoned out, the entry of air stopping the action.
