    摘要: The new petroleum breakers are obtained by subjecting (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.degree. to 80.degree. C. in the presence of an alkaline catalyst, to a condensation reaction at 80.degree. to 150.degree. C., after prior neutralization and, if appropriate, in the presence of inert solvents, with (b) a block polymer which has been prepared by reacting polypropylene 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 product, 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 condensation product, in an addition reaction, to the etherified phenol/aldehyde condensation product thus obtained. When used for separating petroleum emulsions, they effect, in particular, a high and rapid removal of salt.

    摘要: Modified benzyl ether-containing resole polyols derived from a phenolic component, a non-aqueous aldehyde, and a halogen-containing aliphatic hydroxyl component are prepared using a metal derivative as a catalyst. These polyols react with organic polyisocyanates to yield closed cell, low friability, low combustibility, rigid polyurethane foams without the need for post curing at elevated temperature. They are also useful in the preparation of modified rigid polyisocyanurate foams.

    摘要: Modified benzyl ether-containing resole polyols derived from phenol, paraformaldehyde and an aliphatic hydroxyl compound are prepared using a metal derivative as a catalyst. These polyols react with organic polyisocyanates to yield closed cell, low friability, low combustibility, rigid polyurethane foams without the need for post curing at elevated temperature. They are also useful in the preparation of modified rigid polyisocyanurate foams.
