PROPERTIES OF MTBE Click to edit text stylesEdit your company sloganwww.themegallery.com2.1 Chemical physics of MTBE Methyl tert-butyl ether---MTBE MTBE is a volatile, flammable, andcolorless liquid that is sparingly soluble inwater. It has a minty odor vaguelyreminiscent of diethyl ether, leading tounpleasant taste and odor in water

I-C4= from Steam Crackers (SC)The isobutylene content canvary from 35 to 50 vol%, with about 44 %considered typicalB.I-C4= from Refineries (FCC)The isobutylene concentration is muchlower inthis mixed butylene stream compared to thesteam cracker mixed C4s stream
