Title: Improvements in and relating to the preparation of detergent compositions
Inventor: PENGILLY PETER JOHN
IPC: C07C303/06
Filed: 1957-02-06
Abstract: The invention comprises a process for the preparation of a detergent composition of low inorganic salt content, in which the reaction mixture obtained by sulphonation of an aromatic organic material having a C8-C20 alkyl group in the molecule, after removal of free sulphuric acid by a known process, is mixed with at least 20% of its own weight of a C1-C4 aliphatic alcohol and/or a C3-C4 ketone, or a mixture of two or more of the above alcohols, and/or ketones, an amount of water which is not greater than the weight of alcohol and/or ketone used, and an agent in an amount calculated as sufficient to react with the free sulphuric acid present in the reaction mixture so as to form a crystallizable sulphate, but not substantially more than sufficient to neutralize the free sulphuric acid completely, the precipitated material so obtained in the treated reaction mixture is separated, and the resulting sulphonic acid neutralized and worked up to the required product.  The preliminary removal of the free sulphuric acid may be carried out, e.g. by settling and running off, or centrifuging.  The process of the invention may be applied to e.g. sulphonation products of dodecylbenzene.  Alcohols and ketones specified are methanol, ethanol, propanol, iso-propanol, butanol, iso-butanol, propylene glycol and acetone.  Suitable neutralizing agents are caustic soda, soda ash, sodium bicarbonate, caustic potash, ammonia.  The amount of agent used should be such that a crystallizable sulphate is formed such as the neutral or acid sulphates or double or mixed sulphates, preferably such that the acid sulphate is precipitated.  The water, alcohol and/or ketone, and neutralizing, agent may be added to the pre-treated sulphonation product in any order.  The sludge so precipitated may be removed, e.g. by centrifuging or filtering and is preferably washed with fresh alcohol and/or ketone, which is to be added to the next batch.  The process may be carried out at 50-130 DEG  F., and the purified product so obtained may be neutralized with any desired base.  The alcohol and/or ketone used may be recovered by distillation from the neutralized, purified sulphonic acid, or left in the product.  Examples are given of the application of the process of the invention to the product of the sulphonation with oleum of dodecylbenzene, and of a mixture of toluene and dodecylbenzene.

Abstract: The invention provides 1:1-monoazodyecobalt complexes of formula <FORM:1094746/C4-C5/1> in which A is a phenylene or naphthalene radical X11 is -O- or -COO- in ortho position to the azo group, B is any coupling component with an o-hydroxy or vicinal enolizable keto group, n is 1-3, R1, R2 and R3 each represent a molecule of ammonia or of a primary, secondary or tertiary monoamine.  The 1:1 complexes are made by reacting a dye of formula <FORM:1094746/C4-C5/2> in which the symbols are as above and X is -OH or -COOH with at least one molecular proportion of a cobaltous salt and ammonia or a primary, secondary or tertiary amine, or a complex formed therefrom, the reaction with the complex being effected in water or organic liquid preferably miscible with water or a mixture of water and a water miscible organic liquid.  Preferably, the reaction is carried out in an inert atmosphere.  Alternatively, the metallizable azo dye is reacted with cobaltous salt, whereby a 1:2 cobalt complex is formed and this is reacted when excess cobaltous salt is present with ammonia or amine or when insufficient cobaltous salt is present the 1:2 complex is reacted with a complex of cobaltous salt with ammonia or the said amine. The products obtained are valuable as dye intermediates and as dyestuffs for dyeing various cellulosic, polyamide, polyolefine and polyacrylinitrate materials.

Filed: 1976-02-06
Abstract: 1513192 Detecting probability of flaws in surfaces DOMINION FOUNDRIES & STEEL Ltd 6 Feb 1976 04757/76 Headings G1G and G1N The surface of a body is tested for the possibility of flaws occurring therein by monitoring the rate of change of hardness along a line in the surface. A cylindrical rolling mill roll is scanned along its surface parallel to its longitudinal axis or helically by an eddy-current hardness tester and a graph obtained on a recorder of the rate of change of hardness along the scan. If the rate of change of hardness exceeds a predetermined value or if an acceptable rate of change is immediately followed by another high value of change in the opposite direction then there is a greater possibility that if the roll is used again defects such as spawls or cracks will occur in the surface. Graphs and figures of values of rate of changes are given. When the hardness readings indicate the possibility of faults the roll may be cut or ground, heat-treated or surface annealed until parts are exposed which have an acceptable rate of change. Hardness may be detected ultrasonically, infrared examination of a heated roll or holographically.
