Reactivation of Boron Phosphate Catalysts for the Synthesis of Isoprene from 2-Methylbutanal Dehydration
Hutchings, Graham J. Hudson, Ian D. Timms, Donald G.
Boron phosphate catalysts, when used for the title reaction, are deactivated both by coke deposition and by loss of surface phosphorus; air reactivation at 800 deg C is shown to totally restore the catalyst structure and performance.
Trifluoroacetylation of ketone O-vinyloximes
Vasil'tsov Shmidt Mikhaleva Zaitsev Tarasova Afonin Toryashinova Il'icheva Trofimov
Ketone oxime O-vinyl ethers having alkyl or phenyl radicals react with trifluoroacetic anhydride in ether in the presence of pyridine, yielding 43-54% of the corresponding ketone oxime O-(trans-4,4,4-trifluoro-3-oxo-1-butenyl) ethers with high stereoselec
