Patent US9,845,450 issued on Dec 26, 2017 showing that VBC groups can improve the stability of alkaline anion exchange membranes

Patent US9,845,450 issued on Dec 26, 2017.  The patent is a continuation of our efforts to demonstrate that tetramethylimidazolium (TMI) functionalized styrene alkaline anion exchange membranes are useful for alkaline water and alkaline CO? electrolysis.  This patent shows the importance of having extra vinylbenzyl chloride (VBC) units in the polymer to promote stability.  TMI, itself is not stable in alkaline … Read More

Patent US9,790,161 issued Nov 27, 2017

Patent US9,790,161 issued on Nov 27 2017.  Italso issued recently in China on Dec 3, 2017 as CN105339336.   This patent provides a new route to the production of acrylic acid from CO2  and acetylene. First the CO2  is electrolyzed to produce formic acid.  Then the formic acid reacts, via a number of intermediates to form acrylic acid. There are two unique parts … Read More
