Title: New derivatives of salicylic acid and process for the production thereof
IPC: C07D295/088
Filed: 1954-07-08
Abstract: The invention comprises ethers of salicylamide of the general formula <FORM:0754789/IV(a)/1> wherein Z is a primary, secondary or tertiary amino group, their salts with organic and inorganic acids and their quaternary ammonium derivatives; and their preparation by heating the sodium or potassium salt of salicylamide with an excess of b ,b 1-dihalogendiethylether followed by amination and, if desired, quaternization, of the resulting 2-[b -(b 1-halogenethoxy)-ethoxy]-benzamide.  Suitable aminating agents are ammonia, primary, secondary and tertiary amines and hexamethylene tetramine, and suitable quaternating agents are alkyl halides. Tertiary amino compounds include those in which the nitrogen atom forms part of a saturated heterocyclic ring system.  In examples the intermediate 2 - [b  - (b 1 - chlorethoxy) - ethoxy]-benzamide is prepared from the sodium salt of salicylamide and b ,b 1-dichlordiethyl ether in ethanol.  In separate experiments this intermediate is then heated in benzene solution with ethylamine, butylamine, diethylamine, dimethylamine, methylethylamine, dibenzylamine, piperidine, morpholine and pyrrolidine to form the corresponding salicylamide derivatives of the above general formula. With liquid ammonia the above intermediate gives 2-[b -(b 1-amino - ethoxy) - ethoxy] - benzamide and, as a by - product, bis - [b  - (b 1 - 2 - carbamoyl - phenoxy - ethoxy) - ethyl] - amine.  The former can also be prepared by hydrogenolytic decomposition of the corresponding dibenzyl compound.  Picrates and hydrochlorides of some of the above amino compounds are described.  2-[b (b 1 - diethylamino - ethoxy) - ethoxy] - benzamide gives with ethyl iodide the corresponding quaternary ammonium salt which is also prepared by treatment of 2-[b (b 1-trimethylammoniumethoxy) - ethoxy] - benzamide chloride, itself obtained from 2-[b (b 1-chloroethoxy)-ethoxy]-benzamide and triethylamine, with sodium iodide in acetone.  Medicinal compositions are referred to (see Group VI).ALSO:A therapeutic composition comprises ethers of salicylamide of the general formula <FORM:0754789/VI/1> wherein Z is a primary, secondary or tertiary amine group or a quaternary ammonium salt group, and acid addition salts of the compounds in which Z is a primary, secondary or tertiary amino group, in the form of aqueous solutions, oily solutions or suspensions, tablets, pills, dragees, sticks, suppositories or salves.  Mixtures of the salicylamide ethers are also referred to.

[Class 32] In a process of the kind in which mixtures of fatty acids and neutral oils, e.g. the " foots " obtained in the refining of animal and vegetable oils with alkali, are fractionally distilled to separate the individual acids by heating the mixture with steam under vacuum and injecting the vapours obtained into a tractionating tower where they are fractionated in counter current with :a reflux of fatty acids of increasing saturation and from which fatty acids are withdrawn as side fractions, the neutral oil is withdrawn from the bottom of the fractionating tower, reheated, and returned thereto. The fatty acid stock from a tank 10 is fed through a preheater 13 into a mixing chamber 19 where it is mixed with neutral oil recycled through line 25 and steam injected through line 26. The mixture is passed through a tubular heater 14 heated by a mixture of diphenyl and diphenyl oxide vapours to 600‹F. into a fractionating tower 24 provided with upper and lower banks of trays 30, 32 and maintained under high vacuum. Vapours pass off through line 37 and condenser 38 into a mist extracting tank 40 in which a pool of condensate is maintained by a liquid level control 42 and is heated to 150'F. by a closed coil 44. The steam passes from the line first downwardly and, then upwardly through a bubble plate 45 and baffle plates 49, 50 finally leaving through line 51 and barometric-vacuum vessel 52. Part of the condensate from the pool and the plate 45 is recirculated as reflux through line 54 to the top of the tower. A side cut comprising chiefly oleic and linoleic acid is removed through line 55 and stripped in tower 56 with steam fed through line 58. The residual liquid collecting at the bottom of the tower and comprising glycerides and tar is removed through line 25 and recirculated in part to the mixer 19. The remainder is fed to tank 35 where it is hydrolysed the fatty acid set free being separated by distillation. U.S.A. Specification 2,054,096 is referred to.

Abstract: 623,749. Printing-machines. NATIONAL MARKING MACHINE CO. July 12, 1946, No. 20975. Convention date, July 12, 1945. [Classes 100 (i) and 100 (ii)] A machine for printing and cutting the printed tags from the tape which is fed intermittently to the platen of the machine is constructed with a printing-head 12 fitted with type wheels 14, and as the head 12 is lowered the tape is fed forwards from a reel 45 by means of reciprocating grippers carried by a carriage 63, 64, 65, moving on guides which is reciprocated by a slotted lever 86 which is actuated by a projection 98 on a rod 95 which descends with the printing head 12. On the upward movement of the head 12 a cutting blade 102, carried by a curved lever 100 is actuated by a link 115 having a slot 117, the link being connected to the head 12. The slot 117 engages a roller 114 on a drive plate 106 rotating it clockwise and causing, by the action of a pin 109 on the slotted end of a plate 103 secured to the lever 100, a counterclockwise movement of lever 100 and knife 102. The portion of tape extending through a slit- 17 in a plate 16, secured to the platen 15 is thus severed. An adjustable lug 120 on the plate 106 frees the link 115 after the cutting operation, and springs 112, 118, return the parts to normal position. The cutting mechanism may be put out of action by means of a rod 123 connected to the link 115, and operated by projection 126. The tape T is led between rollers 30, 31, which act as tensioning rollers, but these may be held apart when desired by a yoke 36 depressible by a key 41. The feed grippers comprise a lower gripper 67 and an upper one 71 mounted on a spring-controlled plunger 70 provided at the top with a camsurface 75 and with a pin 73 engaged by a spring 72 tending to keep the grippers open. As the grippers move towards the platen 15 they are maintained closed by the crossmember 78 of a pivoted yoke 76 which operates on a point 74 above the cams 75. The grippers are opened at the end of a feed stroke by a pin 51 on a bar 49 which moves the yoke 76 to the position shown by dotted lines in Fig. 5. On the return movement of the feed carriage a block 52 engages an extension 80 of the yoke 76, and the grippers are again closed. The block 52 is adjustably connected to the bar 49 by means of a spring-pressed pin 56 which engages a desired hole 50 in the bar. An index and scale may be used with the block 52. A pin 81 limits the clockwise movement of the yoke 76, and a plate 65 the reverse movement. The cut tag is removed from the platen by a flipper member 128, 129, 130, which is operated against the action of a spring 131 by means of a spring member 133, 134 carried by the head 12.
