标题:Fluorinated silica catalyst and preparation of aromatic/aliphatic nitriles in the presence thereof
发明人：JACQUES ROLAND; REPPELIN MICHEL; SEIGNEURIN LAURENT
权利人:RHONE POULENC SPEC CHIM
摘要:An improved fluorinated siliceous catalyst, well adapted for the catalytic synthesis of aromatic/aliphatic nitriles from their corresponding formamides, formanilides or amides, is comprised of a plurality of silica particulates, the specific surface of which ranging from about 200 to about 300 m 2 /g, having a total pore volume ranging from about 1 to about 1.5 cm 3 /g, with an average pore diameter ranging from about 100 to about 200 â„«, having an exchange pH of less than about 3, and with the fluorine content thereof bonded to the silica, expressed in F 31 , ranging from about 0.05 to about 2% by weight based upon the silica, and the sodium content thereof, expressed as Na 2 O, being less than about 1% by weight, also based upon the silica.

标题 :Preparation of aryl trifluoromethyl ethers
发明人：FEIRING ANDREW E
权利人:DU PONT
摘要:A one-step process for the synthesis of aryl trifluoromethyl ethers by reacting phenol or certain substituted phenols with a perhalomethane and hydrogen fluoride is provided. The compounds produced by the process of this invention are useful intermediates in the production of dyestuffs and pharmaceuticals.
