摘要:
A silica catalyst that retains its high initial activity for a longer time is obtained by forming the catalyst from an aquasol that was obtained by mixing an alkali metal aluminate with an aqueous solution of alkali metal silicate.

摘要:
The present invention relates to a process for making a composition comprising at least two different ethers using ethanol, or a combination of ethanol and methanol, as a starting material.
摘要:
A process is provided for making a reaction product comprising 1-butanol by contacting a reactant comprising ethanol containing a significant amount of water with a decomposed hydrotalcite catalyst. The catalyst may be 1) hydrotalcites which have been thermally decomposed, either partially or fully, to form catalytically active species; 2) combinations of hydrotalcites (optionally containing transition metals) and metal carbonates; and 3) hydrotalcites (optionally containing transition metals) surface-impregnated with a transition metal nitrate, where catalysts 2) and 3) have also been thermally decomposed, either partially or fully, to form catalytically active species. The catalyst, at a selected reaction time, has greater activity when the ethanol contains water as compared to when the ethanol is anhydrous.
摘要:
The present invention relates to the production of butenes and derivatives thereof from dry ethanol, optionally obtained from a fermentation broth. The butenes thus produced find use as intermediates for the production of polyethylenes and other materials.
摘要:
The present invention relates to a catalytic process for making dibutyl ethers using a reactant comprising 1-butanol and water. The dibutyl ethers so produced are useful in transportation fuels.
摘要:
Increased catalyst concentration relative to butadiene in its carboalkoxylation permits operation at reduced pressure and simplifies process steps.
摘要:
The present invention relates to a process for making isooctenes using dry 1-butanol derived from fermentation broth. The isooctenes so produced are useful for the production of fuel additives.
