Special Issue Information
Dear Colleagues,
The search for neoteric solvents to replace ecologically unfriendly organic solvents, in addition to room temperature ionic liquids and deep eutectic solvents, also includes supercritical solvents. The latter are used as reaction media and for the extraction of valuable substances from a variety of materials. The term ‘supercritical fluid extraction’ is generally applied to the use of supercritical carbon dioxide, neat or with entrainers (co-solvents). However, this term should also include other fluids, namely supercritical water, methanol, or ethanol, among a few others.
The use of supercritical carbon dioxide for the decaffeination of coffee beans is presently a well-established industry, but decaffeination of other beverages is coming to the forefront. Other uses of supercritical carbon dioxide are for extraction processes in the food industry and in the pharmaceutical and cosmetic industries, and these are maturing. On the other hand, supercritical water has found uses in the fuel production industry for extraction of liquid or gaseous fuels from coal or the conversion of plant biomass to biodiesel oil. Supercritical methanol is useful for transesterification processes during such extractions.
It is the purpose of this Special Issue of Process on “Advances in Supercritical Fluid Extraction” to highlight recent progress and to point out trends, prospects, and areas in which further research will be very beneficial for this area.

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 100 words) can be sent to the Editorial Office for announcement on this website.
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. Processes is an international peer-reviewed open access monthly 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 2400 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.
