    摘要: High yields of ester-substituted diary carbonates such as bis-methyl salicyl carbonate were obtained by the condensation of methyl salicylate with phosgene in the presence of a phase transfer catalyst (PTC) in an interfacial reaction system in which the pH of the aqueous phase was greater than 9.3. Using the method of the present invention conversions of greater than 99% were obtained whereas under standard conditions using triethylamine as the catalyst conversions were limited to 70-75% of the methyl salicylate starting material even with a 20 mole % excess of added phosgene. The optimized conditions of the of the present invention use only a slight excess of phosgene and represent an attractive route for the manufacture of bis methyl salicyl carbonate and ester-substituted diaryl carbonates generally.

    摘要: A polyethersulfone composition is disclosed which comprises structural units derived from bisphenol-A and 4,4′-biphenol, the structural units derived from 4,4′-biphenol being present in an amount corresponding to greater than 65 mole percent based on total moles of structural units derived from diphenolic monomers, wherein the polyethersulfone has a weight average molecular weight (Mw) of at least 54,000 grams per mole as measured by gel permeation chromatography. The polyethersulfone compositions of the invention display outstanding impact strength as measured using ASTM D256. Surprisingly, the polyethersulfone compositions of the invention show enhanced impact strength relative to known polyethersulfones such as RADEL R, a commercially available polyethersulfone engineering thermoplastic comprised of structural units derived from a dihalodiarylsulfone and 4,4′-biphenol and having a Notched Izod impact strength of about 700 Joules per meter.

    摘要: Oxybisphthalic compounds such as 4,4'-oxybis(N-methylphthalimide) and 4,4'-oxybis(phthalic anhydride) are prepared from the corresponding nitro- or halo-substituted phthalic compounds by reaction with an alkanoate or carbonate salt in a non-polar solvent and in the presence of a hexaalkylguanidinium salt as phase transfer catalyst. A carboxylic acid such as 4-chlorobenzoic acid may be used as an additional catalyst. Reaction rates and yields are higher than with other phase transfer catalysts.
