<VV> Propane

[jvhroberts at aol.com]

That's a pretty good reason to be desirable! N-butanol doesn't have 
anywhere NEAR the octane rating! Nor does isobutanol or sec-butanol! 
Hence the reason TBA is preferred as an octane boosting gasoline 
additive, with the rest of the gasoline being a freeze point 
depressant.

It's desirable only because it has a higher octane rating than the 
other 2
isomers of butanol; they have melting points well below zero 
(Fahrenheit or
 Centigrade) and acceptable octane ratings.

Not to  mention, if one were to use t-butanol, a fairly serious 
physical
property  limitation: It freezes at 77 degrees F! And TBA is the most
desirable  isomer.

Kevin,
While I agree that butanol is probably a better  fuel alternative than
propane, it has one MAJOR disadvantage compared to  propane.  I can buy 

propane
locally right NOW whereas WHERE  do I buy butanol?  Propane is  already
used
not only for  barbecue cooking, but also in many areas for home use
where
natural gas is not available.  Looks like the "chicken or  egg"
situation as
far a butanol is concerned.  It won't be  widely used  until there is a
wide
supply of it and there won't be  a wide supply  of it until it's widely
used!!

As long  as we are  talking about alternative fuel sources, I thought I
would mention   Butanol- It has a energy density very
simaliar to gasoline, is non   corrosive, burns cleaner than gasoline
does,
and, at least in efi cars,  get a  little better fuel milage
than they do on gasoline. It doesnt  absorb water  nearly as much as
ethanol
does, and is much less  evaporative than  either
ethanol or gasoline is. Also, it can easily  be made from a variety  of
non
petroleum sources, although until  recently was made
strictly from  petroleum, for paint solvents. Even  from petroleum,
apparently, it can be  bought for $3.75/gal, and that  is cheaper
than the $4.5/gal that I have to  pay right now for super.  Butanol from
bioderived sources disappeared in the  1950's when  it
became cheaper to make it from petroleum, but in the past  few  years
there
has been alot of innovation that has made
butanol  much  cheaper to produce from bioderived sources than it used
to.
Yes, there are  some issues with running butanol
in a  carburetor car, mostly because it is  more viscous than gasoline
is,
but this is a very simple fix compared to  switching  over
to propane.
