MIXTURE CONTAINING 1,3-BUTADIENE AND PROCESS FOR PRODUCING THE SAME

摘要

To provide a C4 fraction that contains significantly reduced amounts of butynes and methylallene and to provide a process for low-cost and effective production of ethers in which the C4 fraction is used as the starting material for a telomerization process. A mixture containing 25 to 80 mass % 1,3-butadiene, 13 to 68 mass % butenes and 2 to 15 mass % butanes with butynes and methylallene being contained in amounts of 50 ppm or less and 5 to 800 ppm, respectively
