Special Issue Information

Dear Colleagues,

The need for the development of more green chemical processes has encouraged the investment of great research efforts in non-conventional solvents such as ionic liquids, supercritical fluids, or deep eutectic solvents. During the last few years, eutectic solvents have aroused great interest due to their unique characteristic of simple formulation and their low-cost or weak environmental footprint, becoming promising candidates to improve sustainability. In light of this, the aim of this Special Issue is to show the recent breakthroughs and trends in developing new catalytic systems based on neoteric solvents. Thus, I invite you to submit your original research or short review articles related to the application of eutectic solvents in catalysis reactions, the stability of biological or chemical catalysts in the presence of deep eutectic solvents and/or natural deep eutectic solvents, tolerance and toxicity in catalysis, improvements in catalytic processes developed in the presence of these neoteric solvents, or other contributions that improve our knowledge of how these eutectic solvents can improve catalysis reactions. I encourage you to share your work in this field. All manuscripts will be welcome.

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. Catalysts 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 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.

In this study, a quick, simple, green method of converting carbohydrates into 5-hydroxymethylfurfural (HMF) with the use of deep eutectic solvents (DESs) was reported on. We synthesized 12 DESs for HMF conversion from carbohydrates which were studied under different conditions. Under optimal conditions, oxalic acid and citric acid with a choline chloride-based DES produced a maximum yield of HMF at 59 ± 2% and 62 ± 3% in 5 min at 120 °C, respectively. The efficiency of converting glucose to HMF in a short time (5 min) at 140 °C using CrCl3 with a choline chloride-based DES was around 37 ± 1%, which was higher than in previous work. This study demonstrates the significant potential of DESs as a combination for the continuous catalytic transformation of biomass in the synthesis of platform chemicals. Full article

As a versatile and valuable intermediate, furfuryl alcohol (FOL) is widely utilized in manufacturing vitamin C, perfume, fruit acid, lubricant, lysine, plasticizer, dispersing agent, resin, fuel additive, and biofuel. This study aimed at the establishment of a cascade catalysis of biomass to FOL via a hybrid approach in a deep eutectic solvent medium. The catalysis of corn stover (75 g/L) with solid acid AT-Sn-WLS (1.2 wt%) produced 110.5 mM FAL in a ChCl:PEG10000–water (20:80, wt/wt) system at 170 °C for 30 min, and then the formed FAL was biologically transformed into FOL with recombinant E. coli SF harboring aldehyde reductase at pH 7.0 and 35 °C. This established hybrid strategy could efficiently valorize corn stover into FOL, with the productivity of 0.41 g FOL per g xylan in corn stover. Consequently, one combination of chemocatalytic and biocatalytic reactions leading to a one-pot catalytic process was shown as an attractive approach in the valorization of lignocellulose into valuable biobased chemicals.

Microwave irradiation has been used to enhance the reaction yields and selectivities for organic transformation. In this paper, microwave irradiation (MW) was investigated for the environmentally benign synthesis of benzoxazoles through the cyclization of 2-aminophenols and benzaldehydes using deep eutectic solvent (DES) as a catalyst. The [CholineCl][oxalic acid] was easily synthesized from choline chloride with oxalic acid and used without further purification. [CholineCl][oxalic acid] catalyzed the synthesis of benzoxazoles to produce the desired product in a good to excellent conversion and selectivity under MW irradiation. The presence of [CholineCl][oxalic acid] helps to promote the rapid heating transfer from microwave irradiation into the reaction mixture. The [CholineCl][oxalic acid] can be recovered and reused several times without a considerable degradation in catalytic activity. Full article
