Catalytic activity of H3PW12O40/aliquat 336 in epoxidation of (Z,E,E)-1,5,9-cyclododecatriene to (E)-1,2-epoxy-(Z,E)-5,9-cyclododecadiene / Agnieszka Wolosiak in Industrial & engineering chemistry research, Vol. 50 N° 12 (Juin 2011)

The parameters considered included stirring speed, the molar ratios of CDT:H2O2 and H2O2:H3PW12O40, temperature, and the nature and concentration of solvent. The variation ranges of these parameters ensuring a high CDT conversion and high selectivity of transformation to ECDD were established. The CDT conversion was 51.4–55.6% and the selectivity of transformation to ECDD was 79.8–95.1% DEWEY : 660 ISSN : 0888-5885 En ligne : http://pubs.acs.org/doi/abs/10.1021/ie1021738 [article] Catalytic activity of H3PW12O40/aliquat 336 in epoxidation of (Z,E,E)-1,5,9-cyclododecatriene to (E)-1,2-epoxy-(Z,E)-5,9-cyclododecadiene [texte imprimé] / Agnieszka Wolosiak, Auteur ; Grzegorz Lewandowski, Auteur ; Eugeniusz Milchert, Auteur . - 2011 . - pp 7101–7108.
