Chemical Applications of Supercritical Fluids

Dear Colleagues,

According to global trends, industrial processes and academic researchers are always looking for “green” products and technologies that are able to replace conventional ones.

Over the last several decades, there has been renewed interest in supercritical fluids owing to their unique properties and relatively low environmental impact in order to overcome the concerns related to conventional solvents methodologies.

Supercritical fluids are highly compressed gases which combine the properties of gases and liquids in an intriguing manner. Fluids such as supercritical carbon dioxide offer a wide range of unusual chemical possibilities in both analytical and materials chemistry. In addition, supercritical fluids lead to reactions which are difficult or even impossible to achieve in conventional solvents. Finally, supercritical fluids enable selective extractions, opening the possibility to apply the technique in waste valorization, yielding lipophilic compounds with no need of concentration steps, and even more polar ones, with the proper addition of co-solvents.

The present Special Issue entitled “Chemical Applications of Supercritical Fluids” will gather and publish original articles and review papers regarding the use of supercritical fluids as environmentally acceptable alternatives to conventional solvents for extraction, synthetic, analytical, and materials chemistry, on the following topics:

• Bioactives extraction with supercritical CO₂;
• Removal of pollutants/contaminants from matrices;
• Polymerization reactions and purification of polymers;
• Enzymatically assisted reactions;
• Organic synthesis;
• Extraction and purification of food supplements, nutraceuticals, and active ingredients for pharmaceuticals;
• Precipitation/synthesis of nanostructured solids;
• Organometallic and hydrogenation reactions;
• Solute/supercritical fluids phase equilibria studies;
• Mathematical modelling and design of processes.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
