Efficient Microwave-Assisted Esterification Reaction Employing Methanesulfonic Acid Supported on Alumina as Catalyst

Valorisation of Biowastes for the Production of Green Materials Using Chemical Methods

“…Fig. 3 The chemical structure of succinic acid and a selection of conversions that can be performed on it [112][113][114][115][116][117][118][119][120][121] Top Curr Chem (Z) (2017) 375 :46 Many of these molecules can be and are produced from petrochemical feedstocks (e.g. SA is produced by oxidation of butanediol, which is in turn produced by reacting ethyne with formaldehyde); therefore, in addition to bio-derivation, one of the advantages of using these platform molecules is that it avoids the use of toxic or otherwise harmful oxidation agents.…”

Microwave-Assisted Homogeneous Acid Catalysis and Chemoenzymatic Synthesis of Dialkyl Succinate in a Flow Reactor

“…Particularly, SA ester products can be used in the chemical industry as a green solvent, or plastic and fuel additive, as well as in the pharmaceutical and cosmetic industries [6]. Different processes using chemical homogeneous catalysis [7][8][9][10], heterogeneous catalysis [11][12][13][14][15][16][17][18][19][20][21], and chemo-enzymatic reaction [22] have been reported in batch process, but few reports have described continuous flow dialkyl succinate synthesis [21,23]. Among the dialkyl succinates with value-added properties, dimethyl-, diethyl-, di-isobutyl-, and dioctyl succinates can be used as green solvents; dibutyl-, didecyl-, diamyl-, and diisoamyl succinates can be used as plastic and fuel additives; tocopherol, estriol, chloramphenicol, and hydrocortisone succinates as pharmaceutical ingredients; and dipropyl, diethoxyethyl, or diethylhexyl succinates in cosmetic application [1].…”

“…Among the recent reports, Zhang et al described the continuous flow synthesis of diesters 2a, 2b, and 2d in the presence of "man-made" heterogeneous catalyst in quantitative yield [21]. Moreover, Fabian et al described the use of batch microwave radiation as alternative tool for the esterification of SA [14]. To the best of our knowledge, the chemoenzymatic production of diesters 2a-i using both pure SA (1) and pure dimethylester 2b as reactants has never been reported.…”

“…The continuous flow trans-esterification demonstrated a number of advantages, but it resulted in lower yield of the target esters.Catalysts 2019, 9, 272 2 of 10 reactor were developed in 2010 (Table 1). Among them, the use of sulfonic acid was the most described [8][9][10][11][14][15][16][17], followed by carboxylic acid [18] and phosphoric acid [19]. It is difficult to compare each result since the processes were conducted in different conditions by different groups.…”

Interaction of water with methanesulfonic acid on Pt single crystal electrodes

“…Methanesulfonic acid (MSA) is used as catalyst in organic chemistry [1][2][3][4] and electrolyte for electrodeposition (mainly of tin and lead [5][6][7][8][9]) or fuel cells [10][11][12]. MSA is also one of the atmospheric oxidation products of dimethyl sulfide [13][14][15] and it is known to be efficient in forming aerosol particles which serve as cloud condensation nuclei [16].…”
