MODIFIED, ETHERIFIED PHENOL-ALDEHYDE CONDENSATION PRODUCTS, AND THEIR USE IN BREAKING PETROLEUM EMULSIONS

摘要

Phenol aldehyde condensation products of etherified modified prepared by condensation of: (a) a product obtained by reaction of formaldehyde and acetaldehyde.With phenol in the relacionmolar 1: 1 to 3: 1 at temperatures of 50 to 80 * C and an Alkaline Catalyst,With a Polymer Block (b) obtained by reaction of polipropilenglicoles with Molecular Weights of 1300 to 3000 with 20% by weight of ethylene oxide with Alkali Catalysts, the ratio of 0.5 to 4 mol mol 1) with b) Neutralization and Elimination of the Water of reaction; (c) is added to the phenol aldehyde condensation product of etherified 10 to 400 g of Propylene Oxide,For every 100 g of condensation product, or 10 to 200 g of ethylene oxide and Propylene Oxide in the ratio of 1: 0.5 to 14 per 100 g of condensation product.
