Isolation of 3-methyl-1-butene from a hydrocarbon stream
Patent
·
OSTI ID:5342958
A process is described for recovering 3-methyl-1-butene from a hydrocarbon stream containing 3-methyl-1-butene and 2-butyne which forms an azeotrope with 3-methyl-1-butene the process comprising contacting the stream with sulfuric acid having a concentration ranging from 70 to 85 weight percent to form a soluble fraction containing the 2-butyne and the sulfuric acid and an insoluble fraction which contains the 3-methyl-1-butene and recovering the 3-methyl-1-butene through conventional separation techniques.
