Application

1,2-Epoxybutane can be used:
  • As a monomer to synthesize novel initiators via ring-opening polymerization. These initiators can be used to prepare complex macromolecules such as grafted polyamides.
  • To functionalize polyethyleneimine which is used in the synthesis of oxidation-stable adsorbents for CO2 capture.

Features and Benefits

  • High polymerizability
  • Low susceptibility to transfer reaction
  • Ease of handling

Halohydrin hydrogen-halide-lyase, which catalyzes the interconversion of halohydrins to epoxides, purified from a recombinant E. coli was found to catalyze the transformation of 1,2-epoxybutane into beta-hydroxyvaleronitrile in the presence of cyanide. Chloride inhibited competitively the formation of beta-hydroxyvaleronitrile. The enzyme
