  Lipase-mediated desymmetrization of glycerol with aromatic and aliphatic anhydrides

  摘要：

  Chirazyme L-2 (Candida antarctica) catalyzed esterification of glycerol with aromatic and aliphatic anhydrides in 1,4-dioxane is described. All the aromatic monoacylglycerols (MAGs) were produced as (R)-enantiomers, while aliphatic MAGs were obtained either as racemic mixtures or the (S)-enantiomers. The influence of substituted aromatic rings, chain length, and presence of a conjugated double bond in the acyl donor moiety on the enantiotopic selectivity as well as the efficiency of the enzyme was studied.

  Herein disclosed are a filler surface modifier which comprises a phosphoric ester and/or pyrophosphoric ester having a substituent group with a terminal double bond, a filler treated with such a surface modifier, and an unsaturated polyester resin composition and an acrylic resin composition blended with such a surface-treated filler. Such a filler surface modifier eventually not only can increase strength of, namely, provide rigidity for, unsaturated polyester resins filled with CaCO₃ and the like fillers and acrylic resins filled with Al(OH)₃ and the like fillers, but also can reduce viscosity of such resins before curing, thus resulting in improved processability and high filling capacity.
