Title: Process for the preparation of monocyclic ketones with more than nine ring members
IPC: C07C45/48
Filed: 1925-05-18
Abstract: 251,188. Naef et Cie, M. May 18, 1925. Addition to 235,540. Monocyclic ketones; dicarboxylic acids.-Further examples are given of the preparation of carbocyclic ketones having more than nine ring members, according to the process of the parent Specification. In one method a mixture of the thorium and cerium salts of the dicarboxylic acid is used as the starting point, e.g. from a mixture of the cerium and thorium salts of tetra-decane- 1.14. dicarboxylic acid, cyclo-pentadecanone is obtained. In another method, a mixture of ketones is obtained from a mixture of different acids, thus from a mixture of the thorium salts of tridecane-1.13-, tetradecane-1.14-, and pentadecane-1.15-dicarboxylic acids, a mixture of cyclotetra-, cyclopenta-, and cyclohexa-decanone is prepared, and from a mixture of the thorium salts of tetradecane-1.14-, and hexadecane-1.16- dica,rboxylic acids, a mixture of cyclopentadecanone and cycloheptadecanone is obtained. The process may also be carried out in the presence of cerium or thorium, or thorium oxide. Cyclopentadecanone can be prepared by heating to over 400‹ C. tetradecane-1.14-dicarboxylic acid alone, or in the presence of cerium or of acetic anhydride, or bv heating the anhydride of the acid with or without thorium oxide. The ketone may ' be isolated by forming the semi-carbazone which is recrystallized from alcohol and the ketone regenerated by treatment with acid. In the motherliquor of the semi-carbazone is contained a mixture of semi-carbazones which gives on treatment with acids a ketone mixture. The preparation of cyclodecanone, cyclohexadecanone and cyclooctadecanone by heating the thorium salt of the corresponding dicarboxylic acid from 300‹ to more than 400‹ C. in the presence of a good conductor of heat, such as copper or iron turnings, is also described. The ketones obtained may each be oxidized with chromic acid to give a dicarboxylic acid, thus cyclodecanone gives octane- 1.8-dicarboxylic acid, and so on for the others.

In a multi-stage axial-flow turbine or compressor, a shroud ring is disposed in the annular space between the tips of rotor blades of each row and the inner surface of the stator casing, each shroud ring having at least one end face in sealing abutment with an annular end face formed by the root portions of the blades of a row of stator blades and the other end face in sealing engagement with an annular abutment. Each shroud ring thus forms a shield between the working fluid passage and the stator casing. Each shroud ring and each annular member supporting a row of stator blades is supported and guided from the stator casing so as to accommodate relative radial expansion and contraction. The turbine shown comprises a first row of stator blades 13, second and third rows of stator blades 7 and three rows of rotor blades 16, all disposed within a stator casing 1, the diameter of which increases in steps in the downstream direction. The stator blades 13 and 7 have circumferentially abutting platforms 17 and dovetail-shaped blade roots, the roots of the blades 13 being received in grooves formed in the stator casing 1, while the roots of the blades 7 are received in grooves in blade-carrying rings 8 which are supported within the stator casing 1 by means of extensions 11 on the rings engaging in annular grooves 12 formed in the stator casing 1. Radial pins 9 extend through the casing 1 to engage in slots 10 formed in the blade-carrying rings. Shroud rings 15 are disposed in the annular spaces between the tips of the first two rows of rotor blades 16 and the stator casing 1, the shroud rings each abutting at each end against the annular surfaces formed by the adjacent blade platforms 17. The second shroud ring 15 is also engaged by the radial pins 9 which project through the casing whereas the first shroud ring 15 is engaged by radial pins 20. The shroud ring 18 disposed around the third row of rotor blades 16 similarly abuts at its upstream end against the adjacent blade platforms 17, but at its downstream end abuts against a ring 19 secured to turbine stationary structure 2. The ring 18 is also engaged by radial pins 9. The second shroud ring 15 and the third shroud ring 18 are formed with annular recesses 21 with which shroud rings secured to the tips of the rotor blades co-operate. The stator casing 1 is secured at its downstream end to stationary structure 2 and engages at its upstream end in an annular groove 5 in the combustion chamber casing 6 which is also supported from the stationary structure 2. Cooling fluid may be circulated through the spaces between the shroud rings and the stator casing.
