Determination of water in isobutane before and after drying 


Isobutane (i-butane, methylpropane) is used as a coolant and also as a base material in the petrochemical industry. The dehydration of isobutane yields isobutene, an important intermediate product for the production of the fuel additive methyl-tert-butylether.

This Application Note describes the automated determination of the water content in liquid isobutane using the 875 KF Gas Analyzer.

Key words: 2-methylpropane
