This Account presents a survey of recent advances in electrochemical sensing technology relevant to green analytical chemistry and examines the potential advantages, limitations, and applications of these monitoring devices. Stricter environmental control and effective process monitoring have created considerable demands for innovative analytical methodologies. New devices and protocols, with n...

Gilbert's chemistry sets, those that many of today's practicing chemists received as children, proved to be the spark that ignited many a lifelong exploration of the wonders of chemistry. While DuPont was espousing its contributions to the world with its motto, "Better living through chemistry," children were using the popular Gilbert's chemistry sets to perform the simplest experiments and vie...

Since their initial appearance in the scientific literature, the terms "green" and "sustainable" have been increasingly used and are nowadays ubiquitously present in the terminology of several research areas. The seminal origin of what is considered “green chemistry” today might be ascribed to the launch of the Responsible Care® initiative by the American Chemistry Council (ACC) [1] and to the ...

Green chemistry and engineering seek to maximize efficiency and minimize health and environmental hazards throughout the chemical production process. This review demonstrates how green chemistry principles and metrics can influence the entire life cycle of a chemical from design through disposal. After reviewing essential metrics and recent advances in the field within this context, we consider...

a mild and efficient one-pot three-component and environmentally benign approach for the synthesis of a wide range of hydantoin annulated derivatives has been described. a multi-component reaction between a carbonyl compounds (ketone or aldehyde), potassium cyanide and ammonium carbonate (as cyanating agent and amine source, respectively leads to the formation of hydantoins. the proposed optimi...

the solvent free route for the synthesis of diaryl sulfoxides from arenes and thionyl chloride in the presence of lewis acids such as aluminum chloride and ferric chloride on silica gel are described.

objective: dendrimers are three-dimensional nanostructures that have numerous applications in medicine, including drug delivery and imaging. although anionic dendrimer polyethylene glycol–citrate has a high potential to increase solubility of water-insoluble drugs and drug delivery, its multi-step synthesis procedure is time consuming. in addition, toxic substances such as dichloromethane are u...

the condensation of benzylamine with glyoxal leads to hexabenzylhexaazaisowurtzitane (hbiw) in acetonitrile solvent with citric acid as a green catalyst under both conventional stirring and ultrasonic irradiation conditions. the influence of four variables, including the amount of catalyst, solvent, reaction time and ultrasonic power, on the reaction yield was investigated. the results showed t...

in the chemical industry, process intensification is needed to meet important goals such as sustainable and eco-friendly processes. for esterification reaction the “produce more with less pollution” objective can be achieved by coupling reaction and separation in a so called integrated process. in this work a model for describing the esterification reaction of ethyl acetate in pervaporation mem...
