Abstract

Abstract Novel compounds are produced from aminated alkoxylated aliphatic alcohols and alkyl phenols are described. The compound is formed by reacting the nitrogen atom with certain compounds to form hydroxyl, carboxyl or sulfonate terminated compounds susceptible to salt formation with Group 1a and 2a metals, particularly sodium and potassium, to increase the water solubility of the compound. These compounds, particularly the salts of these compounds, are useful surface active agents and are soluble in polar and non-polar solvents. They are useful as oil and fuel additives, anticorrosive agents, detergents, froth flotation and oil recovery chemicals, and certain metal salts of the compound are useful as isocyanurate catalysts.
