The catalytic activity of niobic acid treated with nitric acid and phosphoric acid in the synthesis of ethyl tert-butyl ether(ETBE) had been studied.

ETBE Production Technology;

Synthesis of ETBE Over Heteropoly Acid Immobilized SiO_2 Catalyst;

A reaction kinetic model for synthesis of ETBE from ethanol and tertiary butyl alcohol,catalyzed by HF/USY modified by hydrofluoric acid,was established.

The catalytic activity of the alkali-treated mordenite with template for ethyl tertiary butyl ether (ETBE) sy.

The synthesis of ethyl tertiary butyl ether (ETBE) from isobutene and ethanol has been investigated on different zeolite catalysts at temperatures from 45 to 90 ℃ and pressures from 1 3 to 1 8 MPa.

The technical analysis by simulation was performed aiming at how to revamp methyl tertiary butyl ether(MTBE)unit based on catalytic distillation process with mixed phase reactor to produce ethyl tertiary butyl ether(ETBE).

The synthesis of ethyl tert-amyl ether(TAEE) was chosen as a model system.

1013MPa) for the five binary systems including ethanol water,tert butyl alcohol water,ethanol tert butyl alcohol,ethyl tert butyl ether ethanol,tert butyl alcohol ethyl tert butyl ether respectively and a quaternary systems of water ethanol tert butyl alcohol ethyl tert but yl ether.

Ethyl tert butyl ether was prepared from ethanol and tert butyl alcohol on strong acid cation exchange resin via reactive distillation coupled with pervaporation.

The synthesis of ethyl tert butyl ether (ETBE) with ethanol (EtOH) and tert butyl alcohol (TBA) by using A 15, S 54 and D 72 strong acid cation exchange resins as catalysts was studied.
