Prodn. of propylene oxide (I) and acetic acid (II) comprises liq. phase oxidn. of propylene and acetaldehyde with an O2 contg. gas at 70-100 degrees C. and 40-50 atmos., in presence of a boride of Ta, Mo, Zr or N as catalyst. The catalyst is pref. 0.1-0.2 wt.% on the reaction mixt. Prods. are intermediates for polymers, synthetic fibres and solvents. The catalysts increase selectivity of (I) prodn. from acetaldehyde, e.g. to 93 mole %. Pref. a reactor is charged with catalyst and starting materials, brought to temp. and pressure (esp. 70-80 degrees. and 40 atmos.), then a gas contg. 10-100 vol.% O2 passed through. Reaction is esp. for 1-1.5 hr. and prods. are recovered by fractional distn. |
