Title: Improvements in or relating to corrosion inhibiting compositions
IPC: C10L1/24
Filed: 1954-05-18
Abstract: An ammonium salt of a sulphonated alkyl benzene is prepared by bubbling gaseous ammonia through a sulphonated alkyl benzene which may be prepared by reacting an alkyl benzene with sulphuric acid maintained below 50 DEG  C., and removing the acid sludge.  Suitable alkyl benzenes for the above reaction may be prepared by alkylating benzene with a polymerized hydrocarbon containing 9-15 carbon atoms, for example polypropylene prepared by contacting propylene with a polymerization catalyst such as phosphoric acid on kieselguhr or silica gel at a temperature of 300 DEG -350 DEG  F. and a pressure of 200-5,000 lb./sq. in.  In the example, benzene is alkylated with tetrapropylene at a temperature below 50 DEG  C. in the presence of anhydrous aluminium chloride and chloroform.  An ammonium salt of a phosphoric acid ester is prepared by treating the reaction product of P2O5 and an alcohol with ammonia.  Alcohols referred to are alkyl, aryl and cycloaliphatic alcohols, e.g. monohydric primary alcohols having 6-18 carbon atoms.  The preparation of the ammonium salt of di-(isooctyl) phosphoric acid is referred to.  Mixed salts may be obtained by adding ammonia to a mixture of a sulphonated alkyl benzene and an alkyl derivative of phosphoric acid.ALSO:Corrosion of iron or steel surfaces such as those of storage tanks and pipelines in contact with petroleum distillation products such as gasoline, kerosene, gas oil, heating oil or lubricating oil containing traces of moisture, is prevented by adding to the gasoline, &c. an oil soluble inhibiting composition consisting of a mixture of an ammonium salt of a sulphonated alkyl benzene and an ammonium salt of an alkyl or aryl derivative of phosphoric acid, from 1/4 to 25 pounds of the composition being added to each 1,000 barrels of distillate. Preferably the ammonium salt of the alkylated benzene sulphonic acid is prepared by reacting ammonia with the acid made by sulphonating benzene alkylated with tetra-propylene, whilst the other salt is prepared by reacting ammonia with the acid made by adding phosphorous pentoxide to iso-octyl alcohol, the composition consisting of a mixture of one part by weight of the first salt with one to three parts by weight of the second.

Abstract: 748,290. Electromagnetic interrupters. DONAT, E. May 27, 1953, No. 14798/53. Class 38(5) [Also in Group XVIII] In an electro-magnetically maintained pendulum device the pendulum 1, Fig. 1, carries a permanent magnet'2 2 of the polarity shown, oscillating in an air gap of the yoke of an electromagnet 5. The said yoke has a second air gap 6 in which is located the south pole of a polarized armature 7 connected by a spring 9 to a permanent magnet 8 which has north pole shoes 10 which embrace the armature 7. The arrangement is such that when the .permanent magnet 2 is in the first air gap of the yoke of the electromagnet 5, which is unexcited, the said yoke is induced with the polarity shown in full lines to cause the armature 7 to assume the position shown and so close the contacts 12, 13. The electromagnet 5 is thereby excited and its yoke assumes the polarity indicated in dotted lines so that the permanent magnet 2 is impulsed and the armature 7 is moved to the other pole in the air gap 6. The armature 7 is retained in the position to which it is moved by the corresponding pole shoe 10 until the permanent magnet 2 again enters the first air gap. The device for counting the oscillators of the pendulum may be electrically operated on closing of the contacts 12, 13 or mechanically by the armature 7.
