Degradation of phenethoxybenzene in sodium hydroxide
Administrators only until June 2017 | Request a copy from author
Simple lignin model compounds containing β-O-4 aryl ether linkages have been utilized as a means to understand lignin depolymerisation. The effects of, reaction temperature and time, catalyst concentration, initial phenethoxybenzene (PEB) on the degradation of PEB in NaOH was investigated. Operating at 300 oC for 1 h resulted in the highest combined yield of the primary products, phenol and styrene, and also resulted in the reduced amount of degradation products formed. The proportion of oligomeric and polymeric materials formed depended on the NaOH concentration, but not on the initial PEB concentration for equal reaction time. The results were used to propose reaction pathways for PEB degradation.
Impact and interest:
Citation counts are sourced monthly from and citation databases.
These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
