PROPİYONİK ASİTİN İZOBUTİL ALKOL İLE AMBERLYST 36 VE AMBERLYST 70 KATALİZÖRLERİ VARLIĞINDA ESTERLEŞME KİNETİĞİ

When catalyst meets reactor: continuous biphasic processing of xylan to furfural over GaUSY/Amberlyst-36

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...

Kinetic Study of the Heterogeneous Catalytic Esterification of Acetic Acid with Methanol Using Amberlyst®15

The bulk chemicals esters contribute to commodity chemicals in nearly unlimited variety. Common fields of application include their use as solvents, plasticizers, surfactants, flavours, inter mediates in preparative organic chemistry, and many more.1 Though well investigated, the technology of ester production offers some challenging characteristics regarding catalysis, operation conditions and...
