Title: Preparation of n, n-diacyldiaminoalkanes
Inventor: TURINSKY OTTO
IPC: C07C233/00
Filed: 1951-03-07
Abstract: A process for the preparation of N,N1-diacyldiaminoalkanes comprises the step of reacting an aliphatic amide of a monocarboxylic acid and an aldehyde with not more than four carbon atoms at a temperature exceeding the melting point of the reaction product in the presence of a catalyst consisting of an inorganic acid or a strong organic acid having an ionization constant at least as high as chloroacetic acetic acid and in the absence of an organic solvent.  The inorganic acids may be added as such or may be produced in situ by adding substances which in the reaction mixture yield inorganic acids.  In carrying out the process the catalyst or the substance yielding it and the aldehyde are added to the molten amide.  The reaction may be represented as follows: 2 R.CO.NR1H + R1CHO--> R.CO.NR1.CHR1.NR1.CO.R + H2O, where R is an alkyl or substituted alkyl radical which may contain such substituents as hydroxyl, halogen and carboxyl which are inert towards the aldehyde under the reaction conditions, R1 is an alkyl radical of not more than three carbon atoms or hydrogen and R1 is an alkyl radical or hydrogen.  The reactants may be employed in stochiometric proportions or either reactant may be in excess.  Amide starting materials mentioned include acetamide, propionamide, butyramide, capric amide, lauric amide, palmitic amide, stearic amide and amides prepared from the mixtures of acids obtained by the hydrolysis of natural oils such as soybean or linseed oil or fractions thereof.  The amides may be primary or secondary and those having from 12 to 18 carbon atoms in an alkyl group are especially suitable.  The aldehyde starting materials mentioned are formaldehyde, acetaldehyde, propionaldehyde and butyraldehyde. Formaldehyde may be introduced into the reaction mixture, e.g. in the form of a gas or a polymer, preferably paraformaldehyde.  Catalysts or substances yielding catalysts in the reaction mixture mentioned include sulphuric acid, hydrochloric acid or phosphoric acid, sulphur dioxide, sulphur trioxide, sulphur monochloride, thionyl chloride, aluminium chloride, the pentachloride, trichloride, pentoxide and oxychloride of phosphorus, strong organic acids such as p-toluene sulphonic acid, oxalic acid and chloracetic acid.  In examples: N,N1-distearyldiamino-methane is obtained on heating commercial stearamide which has been recrystallized from toluene and ethyl alcohol, with paraformaldehyde in the presence of sulphuric acid (I); in a similar process stearamide is employed without purification (II); N,N1-dilauryldiamino-methane is obtained in a similar process from commercial lauric amide and formaldehyde (III); N,N1-diacetyldiamino-methane is similarly obtained from acetamide and formaldehyde, the product being soluble in water and ethyl alcohl (IV); and acetaldehyde is bubbled through heated stearamide in the presence of sulphuric acid as catalyst.  The mixture is further heated and N,N1-diaminostearylethane is obtained (V).

Abstract: 384,633. Stabilizing ships. GES. FœR ELEKTRISCHE APPARATE, 44, Wilhelm von Siemensstrasse, Marienfelde, Berlin. Feb. 24, 1931, No. 5727. Convention date, Feb. 24, 1930. Void [Published under Sect. 91 of the Acts]. Addition to 357,138. [Class 113 (i).] In arrangements for damping the rolling or pitching of ships in which carriages are moved athwart ship or longitudinally of the ship out of phase with the rolling or pitching motion, the motors driving the carriages are controlled simultaneously by means operated from the angle of roll indicator whilst an independent control for each motor is provided to correct uneven movements of the carriages caused by list &c. The movements of the angle of roll indicator 11 are transferred by the motor 12 through the gear shown to the contact arm 2. The movements are also passed by the bevel wheel 16 to the device for producing a lag comprising a spring 45, Fig. 2, the strength of which is regulated by hydraulic damping- cylinders 49, 50 connected by tube 53 provided with the throttle valve 54. The output from the lag device is passed by the gearing shown to the differential 10 and are subsequently combined with the movements directly passed from the angle of roll indicator. The control arm 2 is electrically connected to all the carriage motors and moves across the resistances 4, 5 connected to the mains. The exciting winding 21 of the motor is inserted between the earthed and the positive leads in series with the resistance 22 which is adjusted to correct for the frictional resistance of the individual carriages. The resistance 23 is in circuit with the armatures 24<1>, 25<1> of relays 24, 25. The movements of the individual carriage motors are transferred to the electric motor 29 and thence through the lag device 30 similar to the lag device 17 to bevel wheels 21, 32. Reciprocating movements are thus transmitted to a switch disc 34 in permanent connection with the positive main through the contact 35. Further contacts 36, 37 rest on nonconducting parts of the switch disc and are connected to auxiliary contacts 40, 41, the other members 40<1>, 41<1> of the pair being connected to the relays 24, 25, associated with the armatures 24<1>, 25<1>. In the event of one-sided movements of the carriages caused for example by a list, the switch disc 34 contacts with either the pair of contacts 35, 36, or 36, 37 and with the closure of the contact pairs 40, 40<1> or 41, 41<1> operates the relays 24, 25 to modify the field currents until the movements of the carriages becomes again uniform relative to the fore-and-aft line of the ship.
