KOH A process for 2-vinyloxyethoxymethyl oxirane has
OH(CH 2 ) 2 OH C 2 H 2
been developed and piloted in Russia by Trofimov et al.
CHO(CH 2 ) 2 OH
This proprietary process for Vinylox production is now
CH 2
being scaled up in Russia, since Vinylox has been shown
CHO(CH 2 ) 2 OH ClCH 2 CH

by Russian scientists to be a highly active bifunctional
monomer, reactive intermediate, and building block for

diverse applications. It provides direct and reliable routes
NaOH to numerous compounds with commercial promise such
