Title: Improvements in or relating to the preparation of piperidine derivatives
IPC: C07D211/22
Filed: 1944-09-01
Abstract: Compounds having the general formula <FORM:0595631/IV/1> wherein R1 represents hydrogen or a lower alkyl, hydroxy-alkyl, or an alkoxy-alkyl radical, X represents a radical of the structure <FORM:0595631/IV/2> wherein R2 represents a lower alkyl, a lower alkoxy or a hydroxy radical and R3 represents hydrogen, a lower alkyl or lower alkoxy or a hydroxy radical, or both R2 and R3 together form a methylenedioxy group and one of the radicals Y and Z represents hydrogen and the other a radical of the structure <FORM:0595631/IV/3> wherein R4 and R5 have meanings similar to those assigned to R2 and R3, are obtained preferably by condensing a 2.4- or 2.6-dimethylpyridine with a substituted benzaldehyde of the formula <FORM:0595631/IV/4> to yield a phenethenyl pyridine intermediate in which the two phenethenyl radicals carry identical substituents.  The terms "lower alkyl" and "lower alkoxy" refer to radicals containing not more than eight carbon atoms.  Products carrying phenyl ethyl radicals containing different substituents are obtained by condensing 1 mol. of 2.4- or 2.6-dimethylpyridine with 1 mol. of a substituted benzaldehyde, and subjecting the separated monophenethenyl derivative to a second condensation with a benzaldehyde containing other substituents.  Specifically suitable benzaldehydes are anisaldehyde, p-ethoxybenzaldehyde, m- or p-tolualdehydes, vanillin, isovanillin, piperonal or m- or p-hydroxy benzaldehydes.  The phenethenyl pyridine compounds are next subjected to two alternative treatments: (a) heating with an alkyl, hydroxyalkyl, alkoxyalkyl or aralkyloxyalkyl-arylsulphonate, e.g. methyl-, ethyl-, propyl-, hydroxyethyl-, ethoxyethyl-, or benzoxyethyl p-toluenesulphonate and reducing the resultant phenethenyl pyridinium aryl sulphonate with hydrogen in the presence of a catalyst such as platinum, palladium, nickel or copper chromite; (b) hydrogenating catalytically the di-phenethenyl pyridine compound to obtain the 1-unsubstituted piperidine derivative which may then be alkylated with an alkyl halide, an oxalkyl halide or an oxalkyl halide ether.  The reaction products may be converted into salts by treating a solution of the base with the equivalent proportion of an acid, e.g. nitric, hydriodic, hydrobromic, acetic, lactic, or with normal or acid salts of dibasic or tribasic acids, e.g. tartaric, sulphuric, phosphoric, gluconic, citric.  Numerous examples are given.

Patent GB-426456-A (GB)
Title: Process for producing sulphur by reducing sulphur dioxide
IPC: C01B17/04
Filed: 1934-06-12
Abstract: <PICT:0426456/III/1> In the reduction of sulphur dioxide by reducing gases formed by the passage through a producer of a gaseous mixture containing sulphur dioxide and oxygen, the composition and speed of passage of the mixture being so controlled that the carbonaceous gases formed consist chiefly of carbon monoxide, the carbonaceous material is maintained in continuous movement, e.g. by a rotary grate, so as to provide fresh contact surfaces.  Prior to entry into the converter the gaseous mixture is preheated by the products of the reaction and a second quantity of sulphur dioxide is supplied before the reaction chamber is reached.  As shown, the gaseous mixture containing sulphur dioxide, which may result from the roasting of various kinds of pyrites, is forced by a pump 2 through a pipe 1 traversing a preheater C and a pipe 3 to the rotary hearth 4 of the producer A which is sealed by a water trough 5.  The products of reduction, together with a second supply of sulphur dioxide fed in by pump 7 through a pipe 6, pass to a reaction chamber B filled with contact material which may consist of brick coated with an iron or alkali compound.  From the reaction chamber the gases pass through the preheater C before passing to the condenser where elemental sulphur is removed. Should the roaster gases contain appreciable amounts of arsenic or selenium, the gases are cooled and passed through an electrostatic separator prior to entry into the producer.
