“…Many groups believe that carbamate formation can contribute to increasing the selectivity of the reaction 92. 93 For example, in the asymmetrisation of 1,3‐propanediacetate, when the pressure increases, the ee value improves to 50 % 94. On the other hand, Habulin and Knez94, 95 reported that carbamates may have an effect on enzyme conformation, leading to enzyme deactivation.…”

The 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 the valuable properties of green solvents with the advantages of using biocatalysts for developing cleaner synthetic processes.

“…Lozano et al (2002) found that soluble Candida antarctica lipase B could be dissolved in ILs, showing good synthetic activity, enantioselectivity, and operational stability in scCO 2 for both butyl butyrate synthesis and the kinetic resolution of 1-phenylethanol processes by transesterification. The use of enzymes in ILs and scCO 2 has been summarized in comprehensive reviews and books (Garcia et al 2004, Cantone et al 2007, Habulin 2011. The ILs and scCO 2 have been used separately and at the same time in biocatalysis processes; here, studies of each aspect are reviewed.…”

Ionic liquids (ILs) and supercritical CO 2 (scCO 2 ) are two promising types of reaction media for green chemical processes due to their unique properties. They can be integrated into chemical reactions as catalysts and solvents to develop green and environment-friendly processes. This review presents current research trends aiming to solve the major chemical engineering issues in light of a fundamental understanding of these media. Applications of these media in the petrochemical industry, biochemical engineering, and fine chemical production are reviewed, suggesting the challenges and directions of utilizing them for green processes prospectively. These recent explorations and successful examples of applications demonstrate that ILs and scCO 2 offer huge potential for novel and green chemical engineering processes.

“…In recent years, supercritical fluids have been experiencing an increasing interest as solvents for enzymatic reactions. 190,191 Especially, supercritical carbon dioxide ( sc CO 2 ) appears to be an interesting green solvent for biocatalysis: its critical temperature and pressure (31.1 • C and 7.38 MPa, respectively) are compatible with the requirements of enzymes. Besides being cheap and safe to handle, sc CO 2 performs as a hydrophobic solvent (polarity comparable to n-hexane) with tuneable solvent properties.…”
