QUATERNARY OXYALKYLATED POLYCONDENSATE, ITS PRODUCTION AND USE |
摘要 |
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. |
