1,126,783. Olefine oxides; alcohols. HALCON INTERNATIONAL Inc. 27 June, 1966 [28 June, 1965], No. 28617/66. Heading C2C. [Also in Division C5] Ethylbenzene or cumene is oxidized with O 2 to ethylbenzene hydroperoxide or cumene hydroperoxide respectively and an olefin oxidized to an olefin oxide with said hydroperoxide whereby the hydroperoxide is converted toα- phenylethanol orα,α-dimethylbenzyl alcohol respectively. These alcohols and the olefin oxide may be dehydrated separately to give a styrene and a diolefin (see Division C5). Olefins exemplified are butenes and methylbutenes. The first step may be carried out at 40-180‹ C. at a pressure of 15-1000 p.s.i.a. with O 2 or air. The oxidation of the olefin may be carried out at- 20‹ to 200‹ C. and a pressure from atmospheric to 1000 p.s.i.g. in the presence of a compound (e.g. naphthenate or carbonyl) of Cr, Zr, U, Ta, Mo, Ti, V, W, Re, Se, Nb or Te as catalyst in amount 0À0002-0À03 mols per mol of hydroperoxide. Basic compounds such as compounds of Na, Ka, Li, Ca, Mg, Rb, Cs, Sr and Ba, preferably soluble in the reaction medium, may also be present in amount 0À05 to 10 mols/mol of epoxidation catalyst.
