Ethyl lactate and its aqueous solutions as sustainable media for organic synthesis

Diiodine–Triethylsilane System: Formation of N-Alkylsulfonamides from Aldehydes or Ketones and Sulfonamides

“…14 In addition, ethyl acetate, the solvent that we used in this work, is considered to be a green solvent. 15 Initially, I 2 (0.5 equiv), Et 3 SiH (2.0 equiv), and p-toluenesulfonamide (2a; 1.0 equiv) were used in a sulfonamidation of benzaldehyde (1a) at room temperature for 30 minutes in dichloromethane (DCM) as the solvent. The desired product, N-benzyl-4-methylbenzenesulfonamide (3a), was obtained in 31% yield (Table 1, entry 1).…”

Recent advances in the chemical valorization of cellulose and its derivatives into ester compounds

“…Amongst the cellulose derived product types, esters have received considerable attention due to their unique physicochemical properties and reactivities, which may find important applications in pharmaceuticals, pesticides, fragrances and functional materials. 22,23 For example, levulinates (Levs) can be used as food spice and fuel additives; 23,24 γ-valerolactone (GVL) can be used as a solvent, plasticizer, and also the precur-sor for polyols and olefin synthesis; 25,26 lactates (Lacs) can be used as solvents in the semiconductor industry and as precursors for the synthesis of biodegradable plastics. 27,28 Moreover, the catalytic systems for ester synthesis predominantly rely on alcoholic solvents, which would make product separation and solvent recycling easier as compared to other reaction systems (e.g.…”

Density and Viscosity of Glycolic, Lactic, and Malic Acid Esters

“…At the present time, many published articles provide green alternatives to organic solvents for example compounds obtained from renewable sources. , Biobased organic esters, especially ethyl lactate, have attracted much attention due to their properties: high solvency power, low vapor pressure, nontoxicity, biodegradability, and others. , Ethyl lactate can be used as an alternative to industrial organic solvents and as a solvent for synthesis, , extraction, − magnetic tape coating, and membrane preparation . Methyl lactate is also used as a solvent. , n -Butyl lactate is a food additive and an antimicrobial agent .…”

“…1,3 Biobased organic esters, especially ethyl lactate, have attracted much attention due to their properties: high solvency power, low vapor pressure, nontoxicity, biodegradability, and others. 4,5 Ethyl lactate can be used as an alternative to industrial organic solvents 4 and as a solvent for synthesis, 6,7 extraction, 8−11 magnetic tape coating, 12 and membrane preparation. 13 Methyl lactate is also used as a solvent.…”
