Abstract: The present invention relates to aqueous oil-in-water emulsion containing: a) an oil phase comprising at least one organic amine of the formula (I) R1—(NH—R2)n—NH2 ??(I) wherein n is an integer from 0 to 7, in particular 0, 1 or 2, R1 is a linear or branched, acyclic hydrocarbon group having 12 to 22 carbon atoms; R2 is C2-C4-alkanediyl; b) and water, wherein the amount of amines of formula (I) with n being 1 or 2 is at least 90% by weight, based on the total amount of amines of the formula (I) contained in the oil phase. The invention also relates to the use of these emulsions as a corrosion inhibitor in water-bearing systems.

Abstract: The invention relates to a synergistically active mixture consisting of two components a and b, namely and alkyl hydroxylamine component and an aryl phenol component, for use as oxygen binders in steam generators and boilers. The mixture according to the invention simultaneously acts as a corrosion inhibitor by means of the oxygen binding.

Abstract: The present invention relates to a medium in the form of an aqueous mixture for improving the heat transfer coefficient and use thereof in power plant technology, in particular in steam generating plants. The medium contains at least one film-forming amine (component a) with the general formula: R—(NH—(CH2)m)n—NH2/, where R is an aliphatic hydrocarbon radical with a chain length between 12 and 22 and m is an integral number between 1 and 8 and n is an integral number between 0 and 7, contained in amounts up to 15%.
