The present invention is a demulsifying and corrosion-inhibiting compound formed from the salt of an amphiphilic amine and an amphiphilic acid. In a preferred embodiment of the invention, the demulsifier may be a salt of an alkyl amine and an alkyl aryl sulfonic acid. Even more preferably, the demulsifier may be a salt of a methyl, di-cocoyl amine and an alkyl aryl sulfonic acid. According to another embodiment of the invention, an organic system may be demulsified by mixing the salt of an alkyl amine and an alkyl sulfonic acid with the system to be demulsified.
Abstract:
Diesel fuels, particularly low sulfur diesel fuels, contain additives which increase the lubricity in the fuel and reduce the amount of smoke in the exhaust. These additives are esters having a viscosity of 3.0 cSt to 20.0 cSt at 100.degree. C. and a smoke index of at least 75.
Abstract:
Hydrocarbonaceous fuels and additive compositions therefor which comprise: a) one or more fuel-soluble manganese carbonyl compounds; and b) one or more fuel-soluble alkali or alkaline earth metal-containing neutral or basic detergent salts. These compositions preferably contain, in addition to components a) and b) above, one or more of the following: c) one or more fuel-soluble ashless dispersants; d) at least one fuel-soluble demulsifying agent; e) at least one aliphatic or cycloaliphatic amine; and f) at least one metal deactivator. The compositions possess improved combustion characteristics (e.g., formation of less soot, smoke, carbonaceous products and/or noxious emissions), and form on combustion carbonaceous products of reduced acidity. The deposition of sludge on critical engine or burner parts or surfaces is reduced and the fuels have improved stability and demulsibility characteristics. And the fuel compositions can result in decreased fuel consumption in diesel engines.
