Patent number: 4730079Abstract: Quaternary oxalkylated polycondensates are described; these are prepared by esterifying, with polycondensation, an oxalkylated primary fatty amine with a diol and with a dicarboxylic acid, and oxalkylating the resulting reaction product in the presence of a carboxylic acid. These polycondensates are used as demulsifiers for breaking crude oil emulsion and as corrosion inhibitors in plants for the recovery and treatment of natural gas and crude oil.Type: GrantFiled: July 23, 1986Date of Patent: March 8, 1988Assignee: Hoechst AktiengesellschaftInventors: Manfred Hofinger, Willibald Bose, Martin Hille, Roland Bohm
