Diethyl Ether Production Process with Various Catalyst Type

Abstract

Several H-zeolite and HZSM-5 catalysts was preparated and their characters have also been investigated. H-zeolit Catalyst was preparated from Natural Zeolite that obtained from Malang District and Gunung Kidul District. Diethyl ether was produced by Ethanol with concentration of 95%. This research use fixed bed reactor that 1 gram of catalyst as bed catalyst, atmospheric pressure and temperature 140 o C as the operating condition. Ethanol vapor from vaporization tank was driven by 200 ml/min Nitrogen stream. The responds in this research is liquid product concentration; diethyl ether, ethanol, methanol and water concentration. The results showed that the largest ethanol conversion was produced by the use of 56.44% HZSM-5 and the largest yield of diethyl ether diethyl was produced by the use of alumina and H-zeolite catalyst. The larger ratio between natural zeolite with HCl solvent will produce the larger surface area of catalyst and ethanol conversion. The largest ethanol conversion was produced at reactan ratio 1:20.

Design of MFI Type Aluminum- and Titanium-Containing Zeolites

“…Aluminosilicalites (H 1+ x )[Al 3+ x Si 4+ 12−x O 24 ] × wH 2 O are used in acid-catalyzed reactions such as isomerization and alkylation of hydrocarbons [13], acylation of anisole (C 7 H 8 O) with a propionic anhydride (C 6 H 10 O 3 ) to obtain p-methoxypropiophenone (C 10 H 12 O 2 ) [14], transformation of ethanol (C 2 H 5 OH) into diethyl ether ((C 2 H 5 ) 2 O) [15,16] or ethylene (C 2 H 4 ) [16,17], propane (C 3 H 8 ) conversion with the formation of the main products propylene (C 3 H 6 ) and ethylene (C 2 H 4 ) [16], etc., and as adsorbents for recovery of methanol (CH 3 OH) [18], hydrocarbons (propane C 3 H 8 , propene C 3 H 6 , and n-butane C 4 H 10 ) [19] from carbon monoxide (CO) [20] from the gas phase; and dyes (for example, methyl green [21]), which are used in the staining process (in textile industry) and contaminate wastewater [22]-from an aqueous medium.…”

Evaluation of Diethyl Ether (DEE) as a Renewable Transport Fuel in Sudan

“…This reaction can keep going without end in theory, but because acid is diluted by water and some part of them is reduced to sulfurous acid, the etherification will stop at the end. [3], [4].…”

DEHIDRATACIJA DIETILETERA NA Mn(II)-MORDENITU

“…Jedan od najperspektivnijih načina za ovu konverziju ide od nižih alkohola do uglikovodonika na zeolitnim katalizatorima (1)(2)(3)(4)(5). Mehanizam ove transformacije obavezno uključuje nastanak karbonijum jona, a često ide i uz nastanak etera kao međuprodukta (6)(7)(8)(9).…”

“…Pri tome je prvo bila pripremljena NH 4 + -forma mordenita a potom H-forma mordenita u koju je i uvođen željeni katjon. Namordenit (NaM) je preveden u H-formu jonskom izmjenom katjona Na + u mordenitu sa amonijumovim jonima iz rastvora NH 4 Cl koncentracije 1,0 mol/dm 3 . Žarenjem NH 4 + -forme mordenita na 673 K četiri časa može se smatrati da je sav amonijak uklonjen i tako je dobijena H-forma mordenita.…”
