Naphthenic acids (mostly mono or dicyclic cycloalkane carboxylic acids, e.g., cyclopentane carboxylic acid) are components of naphthenic crude oils. Being corrosive, they have to be removed from crude oils or distillates by alkali extraction in the distillation process. The separated naphthenic acids are marketed as acidic extractants for metals and naphthenates are used as metallic soaps.
Naphthenic acid is a dark coloured liquid with an unpleasant door. Naphthenic acid is insoluble in water. Naphthenic acids will burn though naphthenic acids may take some effort to ignite. The main hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since Naphthenic acids is a liquid, naphthenic acids can easily penetrate the soil and contaminate groundwater and nearby streams. Naphthenic acid is used to make paint dryers, detergents, and solvents
Naphthenic acids are usually obtained by caustic extraction of petroleum distillates boiling between 200 and 370 degree C. A continuous process has been developed for removing naphthenic acids from refinery streams by caustic washing. Caustic extraction also removes other acidic constituents of the petroleum fraction.
Typical of the acid materials present in commercial naphthenic acids are cyclopentylacetic acid and alkyl substituted cyclopentylacetic acids. The mixtures also contain fused chains of cyclopentylacetic acids and small amounts of cyclohexylacetic acids. The factors that propel the growth of the global Naphthenic Acid market research report include its increasing demand owing to various applications such as paint driers, rubber additives and so on. On the other hand, there are also factors that hamper the growth of the market such as inhalation of vapor causes coughing, liquid is moderately irritating to skin and eyes and also excessive exposure could result in dermatitis.
In addition, naphthenic acids have both acute and chronic toxicity to fish and other organisms as they are the major contaminant in water produced from the extraction of oil. The global Naphthenic Acid market research report is classified on the basis of product type, application and geography.
