标 题 :Green chemistry synthesis of the malaria drug amodiaquine and analogs thereof
发明人：FORTUNAK JOSEPH MARIAN; KULKARNI AMOL ANANT; KING CHRISTOPHER
权利人:UNIV HOWARD
摘要:Methods are provided for a green chemistry one-pot synthesis of amodiaquine and amodiaquine analogs. The methods have a lower environmental impact, lower investment cost, reduced amounts of byproducts and impurities, and a shorter synthesis time, compared to current conventional synthesis methods. The methods reduce the total number of steps in the synthesis from four to five down to two, thereby simplifying production; and allow a reduced number of solvents and reagents to be used in production, thereby reducing the waste generated in the synthesis. The methods can reduce the waste to about 3-5 kilograms of waste generated per kilogram of product produced; and surprisingly improve the overall yield from 60-65% to greater than 90% as compared to the current conventional synthesis methods for amodiaquine and its analogs.

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.
