Abstract: 158,154. Coles, S. O. Cowper-. Feb. 20, 1920. No Patent granted (Sealing fee not paid). Rotary furnaces. - A rotary sherardizing-drum is mounted on a wheeled carriage arranged on a track which facilitates introduction into, or removal from, a furnace-chamber, the drum being heated both externally and internally by the combustion products which circulate around the drum and are exhausted through one or more internal tubes. Fig. 1 shows a singletubed drum a, supported by rollers e, provided with a charging and discharging door d communicating with the annular space c into which the zinc dust is introduced when the drum is retracted from the furnace chamber. The drum is revolved by one of the rollers e which is detachably connected with external driving-mechanism by means of a shaft which passes through the furnace-chamber door i. The drum is heated by gas-burners i arranged below a casing k which is secured to the carriage f and partially surrounds the drum a, the casing guiding the furnace-gases around the drum and also acting as a discharge hopper when the carriage f is withdrawn and the door d is removed. In a modification, a number of eccentrically arranged internal tubes are provided through which the gases escape to the chimney l, and a smaller centrally-arranged tube is provided to hold a pyrometer. In a further modification, the combustion products from a solid-fuel grate are first passed through the internal tube or tubes and then circulated externally before passing to the chimney, a baffle being provided to prevent the gases from passing direct from the internal tubes to the chimney without first circulating around the drum.
Patent GB-759291-A (GB)
Title: Improvements in or relating to the production of secondary amines
IPC: C07C209/48
Filed: 1954-02-23
Abstract: Saturated aliphatic secondary amines are obtained by heating with a hydrogenation catalyst an aliphatic nitrile or a primary aliphatic amine of 8-22 carbon atoms (or mixture of such nitrile and amine) until all the moisture has been removed, contacting the mixture with hydrogen under pressure, maintaining within the hydrogenation zone the ammonia formed until the total amine content becomes constant, discharging the ammonia and continuing the hydrogenation to completion.  Further ammonia may be discharged at intervals during the final hydrogenation.  The entire process should be carried out in the absence of hydroxides and metallic soaps but the presence of an inert bleaching agent is desirable, e.g. 1-3 per cent of finely divided activated carbon or adsorbent clay.  The preheating may be to 120-150 DEG  C. and it is preferable to pass an inert gas through the mixture during this period.  Suitable conditions for the initial hydrogenation are 130-160 DEG  C. and 100-500 p.s.i.g., e.g. 135 DEG C. at 175-190 p.s.i.g.  The catalyst may be Raney nickel in an amount of 0.4-3 per cent based on weight of nickel to weight of nitrile. The ammonia is discharged when the total amine content has ceased to rise, e.g. at about 75-90 per cent.  The hydrogenation is then continued at a higher temperature such as 170-210 DEG  C., preferably 175-198 DEG  C.  The starting materials may be the C12-C18 nitriles or amines obtained from natural fats and may be a mixture.  When a double bond is present this is saturated during the hydrogenation. Examples are given of the process using the nitriles and amines derived from coconut and tallow fatty acids, the products containing some primary amine.

Title: A process for the oxidation of cyclic ethers
Filed: 1946-02-26
Abstract: Aliphatic lactones are produced by oxidising cyclic ethers containing one oxygen atom and four or five carbon atoms in the ring, the groups adjacent to the oxygen atom being methylene groups, in the liquid phase at elevated temperature by means of a gas containing free oxygen.  Suitable temperatures are 70 DEG -200 DEG  C. and increased pressures, e.g. up to 10 atmospheres gauge may be employed. Oxidation catalysts comprising metal compounds or organic compounds may be used, e.g. compounds of cobalt, manganese, iron, cerium lead, copper and chromium; organic acid salts of the metals, e.g. the salts of mono-carboxylic acids, such as the stearates, linoleates, naphenates and acetates and particularly cobalt stearate.  Benzoyl peroxide is also suitable. An inert solvent may be used, e.g. acetic acid or benzene.  In examples: (1) tetrahydrofuran and cobalt naphthenate are heated under pressure, the product is distilled to give a -butyrolactone; (2) tetrahydropyran, cobalt naphthenate and cyclohexane are heated in an autoclave and a stream of air passed through the mixture. Distillation of the product yields a -valerolactone and some formic acid; (3) a -butyrolactone is obtained as in (1), but without the use of a catalyst.  2,5-Dihydrofuran is also specified and yields the lactone of a -hydroxy crotonic acid.
