| 摘要 |
<p>Unsaturated epoxy-alcohols and epoxides are prepared by oxidizing a non-conjugated polyene in liquid phase with oxygen in the presence of a metal of Groups IVA, VA or VIA or a compound thereof, excluding Cr and its compounds, the reaction conditions and the polyene being such that, in the absence of said catalyst, the oxidation would yield substantial proportions of hydroperoxides of the same carbon number as said polyene. Suitable polyenes are 4-vinyl-cyclohexene, 1,5-cyclo-octadiene and 1,5,9-cyclododecatriene. Only one double bond is involved in the oxidation. The catalysts and reaction conditions are those described in Specification 1,016,900.</p> |
