Abstract
Mono-olefins (including cyclo-olefins) are separated from one another by selective formation or decomposition of complexes with a solution of a heavy metal fluoborate or fluosilicate. Selection between olefins may be made by (a) using a temperature at which only one component forms a complex, (b) by using a salt concentration which will effect the formation of only one complex, (c) using insufficient complex-forming salt for all olefins to form complexes or (d) dissolving all olefins and recovering separately by decomposition of the complexes in stages. Complex formation occurs at - 40 DEG to 40 DEG C. and olefins are recovered by heating, preferably to not more than 60 DEG C. and/or by reducing the pressure. Reference is made to the use of salts of silver, copper, mercury and platinum; aqueous silver fluosilicate or fluoborate is preferred. Olefins decrease in solubility in the order (R is alkyl) RCH=CH2> RCH=CHR > R2C=CH2 > R2C=CHR > R2C=CR2 and with increasing molecular weight. Other non-complex forming compounds may be present.
