The extraction procedure of phenols in water solution was studied using liquid DME and n-butane. The procedure could be substituted for phenol extraction using toluene in a methanol-mediated extraction process. The extraction rates of phenol and m-cresol were 84 and 89%, respectively, using 1.5 times liquid DME as much as water in volume, and 91 and 96% by twice extraction, while n-butane was less effective. Based on the results, a conceptual flow diagram of closed extraction process was designed.
