A method for the preparation of phenol, acetone and methyl ethyl ketone

摘要

Phenol is carried out predominantly by hock che cleavage of cumene hydroperoxide, and as coproduct necessarily leads to the same molar parts of acetone is obtained, for which smaller markets in future, however, as for phenol are predicted. Dollars a according to the invention, phenol and acetone, therefore, by oxidation of a cumene and up to 25 w -% seconds - butylbenzene mixture containing and subsequent hock che cleavage of the hydroperoxides is produced, so that, by way of the composition of the reactant mixture the ratio of the useful products of phenol: acetone: methyl ethyl ketone, can be controlled. Dollars a preparation of phenol, acetone and methyl ethyl ketone.
