摘要:
A process for alkoxylating phenols is disclosed. The process comprises reacting a carbonyl-functionalized phenol with an alkylene oxide in the presence of a substantially non-crystalline double metal cyanide (DMC) catalyst. The process offers fast reaction times at low catalyst levels, reduced problems with condensation side reactions, and low-color, low-viscosity, low-polydispersity alkoxylated phenols. The process enables efficient preparation of alkoxylated carbonyl-functonalized phenols that are especially valuable in the surfactant industry.
