摘要:
An organic oxidation catalyst for alcohols which is environmentally less harmful and with which efficient oxidation can be conducted. The oxidation catalyst for alcohols is a 1-alkyl-2-azadamantan-N-oxyl which has a nitroxyl group incorporated in the adamantane skeleton and was synthesized from as a base material a bicyclic compound obtained by the Grob-type ring-opening reaction of 1,3-adamantanediol. Due to the nitroxyl group on the adamantane skeleton, the α-position hydrogen is stabilized based on Bredt's rule and the stability of the oxoammonium group generated by the oxidation thereof is ensured. Compared to TEMPO, which is a conventional oxidation catalyst, this catalyst is reduced in steric hindrance and is usable in a wide range of reaction fields. Because of this, not only a primary alcohol but a secondary alcohol having a sterically complicated structure, which has been difficult to oxidize with TEMPO, can be oxidized at a high efficiency.

摘要:
A method of manufacturing a both-side metallized insulation film comprises steps of: depositing zinc or a blend of zinc and aluminum onto both sides of an insulation film; and winding this metallized film into a product roll. The method is characterized in spraying an oxidizing gas onto a deposited layer on an inner side of the insulation film to be wound, during the winding step. During a vacuum deposition step, an oil layer is formed on at least one side of the metallized film. In addition, an oxide layer is formed by exposing a deposited layer on at least one side to oxygen, or by spraying an oxygen-containing gas onto the deposited layer on at least one side during the winding of the metallized film into the product roll.
