Oxirane compounds by autoxidation: Oxirane compounds by autoxidation. Barone, Bruno J. (Petro-Tex Chemical Corp., USA). U.S. US 3987069 19 Oct 1976, 4 pp. (English). (United States of America). CODEN: USXXAM. CLASS: IC: C07D301-22. NCL: 260348500V. APPLICATION: US 71-170283 9 Aug 1971.Several substances with their cas registry numbers 5076-19-7 and 513-35-9 may be metioned in this study. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) B phosphate and Li phosphate were used as catalysts for oxidn. of Me2C:CHMe (I) with air to 2,3-epoxy-2-methylbutane (II). In a typical run, using B phosphate as a catalyst at 90.degree. and 400 psi air for 3.33 hr, conversion of I was 13.8 mole% and selectivity for II was 65.8%. .

CODEN: URXXAF. CLASS: IC: C07D303-04. APPLICATION: SU 74-2041516 5 Jun 1974. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) The title compd. was prepd. by oxidn. of 2-methyl-2-butene (I) with O or an O-contg. gas at 120-35.degree. in the presence of a Mo-contg. catalyst, e.g., Co naphthenate and Mo resinate. The selectivity of the process and yield of product were improved by using a I-isopentane mixt. at 40-50 atm. and a 30 l./h gas feed rate. .
