ABSTRACT
Based on Bibliometrics and CiteSpace visualization technology, taking 2632 relevant literature from 1992 to 2021 as the analysis object, this paper draws the knowledge map of phase transfer catalysis abroad, and summarizes the development of phase transfer catalysis in recent 30 years. Three research hotspots of synthesis, catalysis, and polyethylene glycol were excavated. It reveals that 1995-2008 is a hot research period in this field.
