摘要

Iodine and iodine cpds. are removed, to a total iodine content below 20 ppb, from acetic acid, acetic anhydride or ethylidene diacetate, obtd. as prods. in carbonylation of dimethyl ether, methyl acetate or methanol in presence of catalysts contg. iodine, by treating the carbonylation prods. at 20-200 deg. C with peracetic acid, diacetyl peroxide or cpds. forming these under the reaction conditions, and sepg. by distn.
