The role of Mn and Fe as promoters of sulfated zirconia (ZS) has been studied in the reaction of acrylic acid (AA) esterification by but-1-ene to sec-butyl acrylate (SBA) at 343K. The main result is that Mn and Fe did not improve the catalytic properties of sulfated zirconia as far as activity and selectivity to sec-butyl acrylate (90–95%) are concerned but strongly improved its resistance to deactivation,...
In order to obtain a new family of acrylic organotitanium polymers which could be of major interest in the field of non-toxic, self-polishing, antifouling coatings, five acrylic organotitanium monomers, three of which are new, were synthesised. They were analysed by n.m.r. and FTi.r. spectroscopy as well as by microanalysis. Their main features were studied from a structural point of view. The...
