An alternative method for the synthesis of acetamidobenzimidazoles (3-6) has been developed, including reacylation methylbenzimidazol-2-ylcarbamate (carbendazim, MBC, 1) under action aliphatic and aromatic carboxylic acids. It was shown that with an increase in size alkyl group reaction temperature (in case butyric acid), due to decomposition resulting product, yield target acyl products sharpl...

a simple highly versatile and efficient sonochemical synthesis of 1,2,4,5-tetrasubstituted and 2,4,5-trisubstituted imidazoles is achieved by condensation of 1,2-dicarbonyl compound, aldehyde, ammonium acetate and primary amine using antimony trichloride immobilized on silica gel (sio2-osbcl2) as a catalyst in ethanol at moderate temperature. operational simplicity, practicability and applicabi...

multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. in this paper, a new clustering based multi path routingprotocol namely ecrr (energy efficient cluster based routing algorithm for improving reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required qos ...

Abstract Annually billions of tonnes aggregates are extracted to apply in civil construction generating environmental impacts and energy consumption. So, based on circular economy principles applying residues as is a good solution reduce the mining activity generate more efficient destination for residues. Thus, this research aims evaluate technical, economic, performance concretes produced ent...
