Abstract of the disclosure: The new petroleum breakers are obtained by sub jecting a) an addition reaction product which has been obtained by reacting aliphatic aldehydes with phenol in a molar ratio of 1:1 to 3:1 at temperatures of 50 to 80°C in the presence of an alkaline catalyst, to a condensation reaction at 80 to 150°C, after prior neutralization and, if appropriate, in the presence of inert solvents, with-b) a block polymer which has been prepared by reacting poly- propylene glycols having molecular weights of 1,300 to 3,000 with 20 to 100% by weight of ethylene oxide in the presence of alkaline catalysts, in a ratio of 0.5 to 4 moles of a) to 1 moLe of b), and removing the water of the reaction which is formed, and c) adding on 10 to 400 g of propylene oxide, relative to 100 g of condensation pro- duct, or 10 to 200 g of ethyLene oxide and propylene oxide in a ratio of 1:0.5 to 14, relative to 100 g of condensa- tion product, in an addition reaction, to the etherfied phenol/aldehyde condensation product thus obtained. When used for separating petroleum emulsions, they effect, in particular, a high and rapid removal of salt.
