REMOVAL OF PEROXIDES FROM A METHYL TERTIARY BUTYL ETHER RECYCLE STREAM (Docket No. 81,063 - F) ABSTRACT OF THE DISCLOSURE An MTBE recycle stream (which consists mainly of TBA and methanol) contaminated with residual amounts of tertiary butyl hydroperoxide, ditertiary butyl peroxide and allyl tertiary butyl peroxide can be effectively catalytically treated under mild conversion conditions with a nickel, copper, chromium, iron catalyst in order to substantially completely decompose the peroxide contaminants and to thereby provide a treated MTBE recycle stream which is not only substantially free from contaminating quantities of such peroxides, but which also contains an enhanced amount of methyl tertiary butyl ether.
