Published in 2019 at "Polymer Bulletin"

DOI: 10.1007/s00289-019-02917-6

Abstract: In this study, ring-opening polymerization of glycidyl phenyl ether (GPE) is performed using tetra-n-butylammonium acetate (n-Bu4NOAc) as a metal- and halogen-free initiator. Various alcohols are used as chain transfer agents (CTAs), of which ethanol yields… read more here.

Published in 2017 at "International Journal of Thermophysics"

DOI: 10.1007/s10765-017-2310-y

Abstract: Semiclathrate hydrates are water-based host-guest compounds formed from aqueous solutions of ionic guest substances. These materials can greatly moderate formation pressures and temperatures from canonical gas hydrates. This is a significant advantage for industrial applications… read more here.

Published in 2017 at "Energy"

DOI: 10.1016/j.energy.2017.04.074

Abstract: Abstract Ionic clathrate hydrates are composed of water and ionic guest substance, which can selectively capture gas under moderate conditions. We performed gas separation experiments with tetra- n -butylammonium bromide (TBAB) widely-used for an ionic… read more here.

Published in 2020 at "Tetrahedron"

DOI: 10.1016/j.tet.2019.130899

Abstract: Abstract 2-Bromo-3-methyl-1,4-naphthoquinone and 2-methyl-1,4-naphthoquinone are highly reactive species known to dimerize in various ways. The product obtained in the dimerization of each compound is primarily dependent upon the solvent used. Ionic liquids represent a new… read more here.
