On the Process of Civilisation in Japan feedstocks to industrial organic chemicals . For economic reasons, these processes predominantly involve the use of molecular oxygen (dioxygen) as the primary oxidant. The success of these processes depends largely on the use of transition metal catalysts to promote both the rate of reaction a

Palgrave Studies on Norbert Eliasn the 21. century. We wish to report the development of novel catalysts that allow the direct, low temperature, oxidative conversion of methane to a methanol equivalent product in 70% one-pass yield. To our knowledge, this is the highest one-pass yield ever reported for methane oxidation to a methyl

The Dual Lenses of Japanese CivilisationR spectroscopy of D.-acetonitrile and by transformation of n-butenes. It has been shown that the high density of strong bridging OH groups or their simultaneous presence with strong Lewis sites support oligomerization reactions to higher olefins, leading via cracking to C.-C. olefins, C. paraffins a

The Dual Lenses of Japanese Civilisationperature and oxygen concentration were examined. Relatively high methane conversion (28–30%) and high selectivity to C. formation (60–70%) is achieved. Time-on-stream of these catalysts does not exceed 18–20 h. Effect of HC1 partial pressure on the CH. conversion and selectivities to principal produ
