Green solvents for green technologies

Journal of Biotechnology, 2018
Green chemistry is a prevention approach to designing products and processes that minimize the use of materials hazardous to human health and environment. Biocatalysis, green solvents, reducing energy consumption by using alternative energy sources (e.g. microwave, ultrasound) are most important tools of green chemistry.

Green solvents for green technologies

Journal of Biotechnology, 2017
In many industrial processes large quantities of volatile and flammable organic solvents are used in various reaction systems and separation steps defining a major part of the environmental and economic performance of a process. Accordingly, a growing area of research in the development of green technologies is devoted to designing new, environmentally-

Applied Biotransformations in Green Solvents

Chemistry – A European Journal, 2010
AbstractThe definite interest in implementing sustainable industrial technologies has impelled the use of biocatalysts (enzymes or cells), leading to high chemo‐, regio‐ and stereoselectivities under mild conditions. As usual substrates are not soluble in water, the employ of organic solvents is mandatory. We will focus on different attempts to combine

Green chemistry - green solvent [PDF]

, 2022
According to the U.S. Environmental Protection Agency (EPA) definition, green chemistry is defined as chemistry that is aimed at designing products and processes that minimize or eliminate the use and production of harmful substances. The green chemistry program developed alternatives to harmful organic solvents – the so-called green solvents. The most

Green solvents for membrane fabrication

2023
Description of membrane fabrication in a more sustainable way. Nowadays, the preparation of membranes still requires the use of aprotic solvents such as N,N-Dimethylformamide (DMF), N,N-Dimethylacetamide (DMA) and Nmethyl- 2-pyrrolidone (NMP) that are considered as toxic and added to the candidate list as substances of very high concern (SVHC) that may

Green Solvent: Green Shadow on Chemical Synthesis

Current Organic Synthesis, 2020
The natural beauty and purity of our planet has been contaminated deeply due to human selfish activities such as pollution, improper waste management, and various industrial and commercial discharges of untreated toxic by-products into the lap of nature.

Practical Approaches to Green Solvents

Science, 2002
Solvents are widely used in commercial manufacturing and service industries. Despite abundant precaution, they inevitably contaminate our air, land, and water because they are difficult to contain and recycle. Researchers have therefore focused on reducing solvent use through the development of solvent-free processes and more efficient recycling ...

Green Chemistry and Green Solvents: An Overview

Current Green Chemistry, 2020
Green chemistry emphasizes designing novel routes to overcome health and environmental problems that occur during a chemical reaction. Green solvents are used in place of conventional solvents that are hazardous to both human and the environment. Solvents like water, ionic liquids, supercritical CO2, biosolvents, organic carbonates, and deep eutectic ...

Green and Bio-Based Solvents

Topics in Current Chemistry, 2018
Chemical reactions and many of the procedures of separation and purification employed in industry, research or chemistry teaching utilize solvents massively. In the last decades, with the birth of Green Chemistry, concerns about the employment of solvents and the effects on human health, as well as its environmental impacts and its dependence on non ...
