<p>A process recovering purified 1,2-butadiene substantially free from ethyl acetylene which comprises distilling of ethyl acetylene from a liquid mixture containing ethyl acetylene and 1,2-butadiene. Namely, a process for producing purified 1,2-butadiene substantially free from ethyl acetylene characterized by distilling a liquid mixture containing acetylene, 1,2-butadiene and 2-butene wherein the content of 2-butene amounts to 40 to 90 % by weight, thus boiling ethyl acetylene together with 2-butene and eliminating the same as the low-boiling components.</p> |
