Synthesis of Novel Series of Coumarin Derivatives
Abstract: In a synthetic method similar to Knoevenagel reaction, 3-acetyl coumarin was prepared in the same way through a cyclization condensation reaction betweensalicylaldehyde and ethyl acetoacetate under basic condition using piperidine. Hence, 3-acetyl coumarin as a starting material was reacted with bromine in ether using a Lewis acid as a reactioncatalyst to produce the corresponding α–bromoaceyl cromen-2-one derivative. In application ofHantzsch synthesis, the reaction of α–bromoaceyl cromen-2-one with thioacetamide in ether …

Grafting of Methyl Methacrylate onto Starch Initiated by Ceric Ion as an Initiator in Presence of Nitric Acid as Activator
Abstract: Natural polymers with improved structure have been securing increasing value in the industry as theyare abundant, cheap, and biodegradable. Graft copolymerization is one of the effective ways toenhance the properties of natural polymers. Starch based graft copolymers are becoming increasinglyimportant due to their remarkable adhesion, high water absorbency, and biodegradability. Methylmethacrylate (MMA) grafted onto starch by using the ceric ammonium nitrate (CAN) as a redoxinitiator in the presence of nitric …

The Advanced Foam Materials Production in Microgravity using the Process of Vibroturbulization
Abstract: Recently, the task of the intensification of the existing technological processes using the intensivemixing of different environment, which are characterized by different densities (water + gas, water +solid particles + gas, water + oil so forth) is actual. The conducted studies determined that at acertain frequency and vibration acceleration of vibration, a resonant phenomenon occurs—vibroturbulization, in which the above of the fluid surface air in a vibrating vessel with fluid …
