LAB REPORT ON CH3(CH2)3OH, BUTANOL

In this lab report, we observed the changes in the pressure of this substance where we were changing its temperature.

"Butanol (also butyl alcohol) refers to a four-carbon alcohol with a formula of CH3(CH2)3OH. There are four possible isomeric structures for butanol, from a straight-chain primary alcohol to a branched-chain tertiary alcohol. It is primarily used as a solvent, as an intermediate in chemical synthesis, and as a fuel. It is sometimes also called biobutanol when produced biologically". (Wikipedia, 2014)

The characteristics of butanol are:

We had butanol connected to the computer, to a program called logger pro.

Temperature (ºC)	Initial (kPa)	Final (kPa)
0ºC	5.00	5.00
16ºC	5.71	7.21
30ºC	11.18	11.25
40ºC	7.34	11.57

In 40ºC the water bath was bigger so we could put the whole shlenk tube in and that changed the results.
