Dehydrocondensation of 1 - hexanol to di - n - hexyl ether ( DNHE ) on Amberlyst 70

Conversion, selectivity, yield and kinetics of 1-hexanol liquid phase dehydrocondensation to di-n-hexyl ether (DNHE) were determined at 150-190 oC on the thermally stable resin Amberlyst 70 in a batch reactor. At 190oC, 1-hexanol conversion of about 71 %, with selectivity to ether of 87 % was obtained after 6-h reaction time. A kinetic model stemming from an Eley-Rideal mechanism in which 1-hex...

Kinetic study of 1 - butanol dehydration to 1 di - n - butyl ether over Amberlyst 70

8 Kinetics of the catalytic dehydration of 1-butanol to di-n-butyl ether (DNBE) over 9 Amberlyst-70 was investigated. Experiments were performed in liquid phase at 4 MPa and 10 413-463 K. Three elementary reaction mechanisms were considered: a Langmuir‐Hinselwood‐ 11 Hougen‐Watson (LHHW) formulation; an Eley-Rideal (ER) formulation in which DNBE 12 remains adsorbed; an ER formulation in which w...

Etherification of Glycerol with Propylene or 1-Butene for Fuel Additives

The etherification of glycerol with propylene over acidic heterogeneous catalysts, Amberlyst-15, S100, and S200 resins, produced mono-propyl glycerol ethers (MPGEs), 1,3-di- and 1,2-di-propyl glycerol ethers (DPGEs), and tri-propyl glycerol ether (TPGE). The propylation of glycerol over Amberlyst-15 yielded only TPGE. The glycerol etherification with 1-butene over Amberlyst-15 and S200 resins p...

Dielectric Properties of 1-Hexanol in Mesitylene Solution on Admixture of Aromatic Dihydric Alcohols

Broadband dielectric relaxation spectra (at 20 to 40 °C) are reported for three liquid alcohol/non­ polar solvent systems: Binary hexanol/mesitylene mixtures and two corresponding ternary mixtures, where 5 percent of hexanol are replaced by a dihydric alcohol, namely resorcinol (1,3-dihydroxyben­ zene) or 2,2'-dihydroxydiphenyl. The concentration of the polar substance(s) ranges from dilute sol...

Iodine-catalyzed etherification of morroniside.

In this study, we describe a highly selective etherification procedure of unprotected morroniside catalyzed by molecular iodine in acetone. The etherification reaction furnished 7-O-alkyl ether derivatives in reasonable yields within few hours under neutral conditions. Studies of the obtained products on cytotoxicity activity in colon 26-L5 cell line were examined. Among the tested compounds, 7...
