Claim 1
Independent Claim
67 words
A PROCESS FOR THE SEPARATION FO 2-METHYLPENTENE-1 AND 2 METHYLPENTENE-2 FROM A MIXTURE THEREOF WITH C6-ALIPHATIC HYDROCARBONS INCLUDING OTHER TERTIARY MONOHEXENES, WHICH COMPRISES CONTACTING THE HYDROCARBON MIXTURE WITH AN AQUEOUS SOLUTION OF A POLYBASIC MINERAL ACIDACTING SUBSTANCE FORMING AN AQUEOUS ACID PHASE CONTAINING ABSORBED 2-METHYLPENTENE-1 AND 2METHYLPENTENE-2 AND A HYDROCARBON PHASE CONTAINING THE UNABSORBED C6-ALIPHATIC HYDROCARBONS, AND RECOVERING THE SAID 2-METHYLPENTENE-1 AND 2-METHYLPENTENE-2 FROM THE ACID PHASE.
