Sodium naphthenates

The aqueous sodium naphthenate phase is decanted from the hydrocarbon phase and treated with acid to regenerate the cmde naphthenic acids. Sulfuric acid is used almost exclusively, for economic reasons. The wet cmde naphthenic acid phase separates and is decanted from the sodium sulfate brine. The volume of sodium sulfate brine produced from dilute sodium naphthenate solutions is significant, on the order of 10 L per L of cmde naphthenic acid. The brine contains some phenolic compounds and must be treated or disposed of in an environmentally sound manner. Sodium phenolates can be selectively neutralized using carbon dioxide and recovered before the sodium naphthenate is finally acidified with mineral acid (29). Recovery of naphthenic acid from aqueous sodium naphthenate solutions using ion-exchange resins has also been reported (30). [Pg.511]

Strong alkaline solutions are used to extract cresylic acid. The aqueous layer contains, in addition to sodium phenate and cresylate, a small amount of sodium naphthenates and sodium mercaptides. The reaction between cresols and sodium hydroxide gives sodium cresylate. [Pg.131]

Soluble cutting oils are mineral oils containing 10 to 50% emulsifiers such as sodium petroleum sulfonates, sodium naphthenates, or sodium rosinates. These compounds allow emulsification of 5 parts or less of the oil in 95 parts or more of water. The emulsion acts as a coolant and, to some extent, as a lubricant (11). [Pg.245]

The commercial production of naphthenic acid from petroleum is based on the formation of sodium naphthenate. Naphthenic acids are recovered by caustic extraction uf petroleum distillates rather than from crude petroleum. Crude naphthenic acid is obtained by acidulating the sodium naphthenate, and can be further refined to remove impurities. [Pg.1053]

Naphthenic Acids. Naphthenic acids are cycloparaffinic organic acids and usually are monocarboxylic. These acids occur in crude oils and normally are recovered with the straight run gasoline and distillate oil fractions in a topping unit. If these fractions are caustic scrubbed, the naphthenic acids are recovered as the sodium naphthenates (5). [Pg.332]

Oxynaphthoic acid (BON acid), a useful organic intermediate used mainly in the manufacture of dyes, is produced by the Kolhe-Scimitt carbonation of sodium naphthenate prepared by reacting naphthalene with sodium hydroxide. The carbonation step is normally carried out in a dry atmosphere, but the possibility of conducting the reaction in a liquid medium such as kerosene has also been explored. The reaction scheme may be represented as... [Pg.553]

When carried out in a kerosene medium, the carbonation occurs in a three-phase system in which CO2 first dissolves in the liquid and then diffuses to the solid naphthenate as a particulate suspension in the liquid. Because the solid is insoluble in kerosene, reaction occurs only in the solid phase. Using the data of Phadtare and Doraiswamy (1965, 1969), reproduced in Table 17.11, formulate a model to predict the conversion of sodium naphthenate to BON acid as a function of time. [Pg.556]
