Abstract

A process for the preparation of a metal salt of an organic acid comprises heating one or more organic acids and/or one or more esters of such acids with lead, copper, cadmium, zinc, iron, nickel, silver or tin, while in contact with oxygen and an antioxidant consisting of one of the following compounds: para-hydroxydiphenyl phenols, hydroquinone, para-aminophenol, p.p1-diaminodiphenylmethane, 2 : 4-meta-toluylene diamine, p diphenylamine, o- and p-ditolylamines, phenyl-alpha-naphthylamine, phenyl-beta-naphthylamine, phenyl-beta-naphthylnitrosamine, symmetrical diphenyldiaminoethane, symmetrical di - beta - naphthyl - para - phenylenediamine, 2 : 4-diaminodiphenylamine; condensation products of amines with carbonyl compounds, e.g. of aniline with acetaldehyde, of alpha-naphthylamine with aldol, of aniline with acetone, and of diphenylamine with acetone; glycollic aldehyde, glyoxal, hydroxy aldehydes from the condensation of formaldehyde with itself, reducing sugars, and amino acid esters such as tyrosine esters. The process may be carried out (a) by passing oxygen or an oxygen containing gas such as air or mixtures of oxygen with inert gases, together with the antioxidant and organic acid and/or ester into a converter having a high ratio of length to its greatest cross-sectional dimension and containing in fragmentary from the metal to be treated, or (b) by passing the gas into a suitable vessel such as the above-described converter, charged with the metal particles, antioxidant and the acid and/or ester. The process is executed at temperatures ranging from 50 DEG to 200 DEG C. and at atmospheric or superatmospheric pressures. The following acids and/or their methyl, ethyl, propyl, butyl and higher alkyl, aryl, aralkyl, glycerol or glycol esters may be used: acetic, propionic, butyric, caproic, lauric, palmitic, stearic, ricinoleic and melissic acids; acids derived from coconut, corn, cottonseed, rapeseed and similar vegetable oils; hydroxy acids such as glycollic, lactic and tartaric acids; polycarboxylic acids such as oxalic, glutaric and adipic acids; unsaturated acids such as acrylic, methacrylic and oleic acids and aromatic acids such as benzoic and naphthenic acids. Specifications 589,242, [Group III], and 600,722 are referred to.
