AN INVESTIGATION INTO SOME OF THE METHODS AVAILABLE FOR THE DETERMINATION OF THE SULPHONATE CONTENT OF OIL‐SOLUBLE PETROLEUM SULPHONATES

Abstract

The present situation in the industry demands reliable and rapid methods of material control, from the raw materials to the final product. New methods and techniques are constantly being introduced to fulfil this requirement; it is essential, particularly for the routine analyst, to choose a method of control which is both precise and rapid. It is the purpose of this paper to investigate some of the methods applicable to the determination of the sulphonate content of the oil soluble petroleum sulphonates. These are believed to consist of the mono sulphonic derivative of hydrocarbons of an approximate formula CnH2n‐13SO3H, containing an aromatic naphthenic nucleus with a long side chain. A brief outline of the manufacture and use of the petroleum sulphonates will be given, together with a brief survey of some of the analytical methods available for their determination; this will be developed to include an investigation of the precision and comparison of two of these methods.
