Abstract
The present invention relates to a process for making dibutyl ethers using dry 1-butanol derived from fermentation broth. The dibutyl ethers so produced are useful in transportation fuels.
Claims3
A process for making at least one dibutyl ether comprising:
- (a) obtaining a fermentation broth comprising 1-butanol;
- (b) separating dry 1-butanol from said fermentation broth to form separated dry 1-butanol;
- (c) contacting the separated dry 1-butanol of step (b), optionally in the presence of a solvent, with at least one acid catalyst at a temperature of about 50 degrees C. to about 450 degrees C. and a pressure from about 0.1 MPa to about 20.7 MPa to produce a reaction product comprising said at least one dibutyl ether;
- and
- (d) recovering said at least one dibutyl ether from said reaction product to obtain at least one recovered dibutyl ether.
