摘要:在乙腈和水的溶液中,使用分子双氧作为氧化剂,实现了一种有效的方法,可将苯酚氧化为氯化亚铜(i)催化的1,4-苯醌.尤其,惰性酚类,如苯酚和单烷基取代的酚,得到有效经由c的选择性激活氧化为1,4-苯醌在h键对位上成c温和的条件下o键.该催化剂对未取代的或烷基取代的苯酚显示出高活性,但对具有吸电子基团的取代的苯酚没有影响.这项研究提供了一种将芳香族酚选择性氧化为1,4-苯醌的好氧方法.

标 题:Water, bubble collapse and syngas species in the synthesis of graphene and its derivatives
发明人：SHANKMAN RICHARD S
权利人:PEERLESS WORLDWIDE LLC
摘要:Hydrodynamic cavitation-inducing inertial, non-inertial, and combination reactors are employed in the hydrothermal synthesis of graphene and its derivatives, both in solution and vapor. Various hydrodynamic cavitation reactor embodiments are revealed. Water is used to both nucleate and 'self-heal' graphene sheet growth in solution and vapor. Various methods of combustion, hydrothermal and dehydration synthesis of graphene and its derivatives are revealed. Additionally, water and ice are used as a substrate, both alone and in combination with other substrates, to grow and recover useful graphene and its derivatives.
