Title: Cyclohexylamine borates and their use as corrosion inhibitors
Inventor: BROWN MICHAEL PETER
IPC: C23F11/14
Filed: 1962-09-27
Abstract: The invention comprises the cyclohexylamine triborates and tetraborates, especially the hydrated forms represented by the formulae C6H11NH2.1.5B2O3.2.5H2O and C6H11NH2.2B2O3.4H2O. The cyclohexylamine borates may be made by heating one mol. of cyclohexy amine with at least two mols. of boric acid, either in a homogeneous phase using a solution of both reactants in a suitable solvent, e.g. water, or in a heterogeneous system using either no solvent or unsufficient solvent.  Where 4 equivalents of boric acid per mol. of amine are used, substantially pure tetraborate is obtained, whereas if 3 equivalents of boric acid are used, a mixture of the triborate and tetraborate in approximately equal proportions is formed. When the proportion of boric acid is reduced to about 2 equivalents, the triborate is usually the only product.ALSO:Cyclohexylamine tri- and tetraborates for use as corrosion inhibitors for ferrous metal articles are applied to the surface to be treated as a suspension of a dust in a suitable liquid, e.g. water or a lower alcohol or ketone, such as methanol, ethanol, acetone or methyl ethyl ketone.

Title: Anti-tarnish composition for copper-containing surfaces
IPC: C23F11/16
Filed: 1962-09-28
Abstract: A composition for treatment of a copper or copper-containing surface comprises a mercaptan of formula CnH2n+1SH, wherein n is from 12 to 25, and a non-abrasive copper-tarnish remover. n is preferably from 16 to 21.  The mercaptan provides a thin, colourless, non-oily protective layer on clean surfaces bonding to the copper through the thiol grouping and the bond resists washing with dilute alkaline or acid solutions and with detergents.  The preferred non-abrasive copper-tarnish removers are acidic cleaners with a pH preferably below 2.5; and comprise a weak organic acid, e.g. citric acid, sulfamic acid and an alkali metal halide, e.g. NaCl,KCd.  HCl is also a suitable cleaner.  Suitable acids have a pH between 1-5, are water-soluble, non-oxidizing and stable.  The aliphatic mercaptan should have from 12-25 carbon atoms illustrated by n-hexadecane-1-thiol, n-dodecane-1-thiol, n-octadecane-1-thiol and n-hemicosane-1-thiol. Controlled additions of mild abrasives may be incorporated in the composition, up to 20% by weight of the formulation, as when removing heavy sulphide tarnish.  Suitable abrasives are finely divided and modified silicas, clays, diatomaceous earths and precipitated chalks.  In addition non-ionic surfactants, viscosity improvers and thickeners may also be present. The thickeners are chosen from colloidal alumina, natural gums, e.g. guar gum, carboxy methyl cellulose, sodium alginate, hectorite &c. and the choice depends on the pH.  The mercaptan concentration should be from 0.5-25.0% by weight, preferably 0.5-10.0%, and in aqueous liquid compositions the prepared formulations contain 1-15% mercaptan, 0.01-25% weak organic acids, 0.01-25% alkali metal halide, 0.05-1.0% surfactant, 0-20% abrasive, sufficient water to emulsify mercaptan and sufficient acid-stable thickeners to provide the desired viscosity.
