Abstract:
Sulfur is "extruded" from various autfur-containino organic compounds by heating the compounds at a temperature of 200-700°C. in the presence of a sulfur-acceptor.
Abstract:
A process for the one esterification of aldehydes and alcohols comprises the steps of combining an aldehyde with an alcohol, in the presence of oxygen and in contact with a catalyst having the general formula PdTe.Zn d E. where E is one or more metals from the group consisting of group IA, IIA, IVA, IB, VIIB, or VIII metals, As or Sb; and a, d and e are from about 0 to 3 with the proviso that at least d or e ≠ 0.
Abstract:
A composite oxidation catalyst is prepared by forming and activating a first oxidation catalyst; forming a second oxidation catalyst; contacting the first catalyst with the second catalyst and a substantially non-aqueous organic fluid to form a composite catalyst; and drying the composite catalyst. The second catalyst may be formed in situ on the first. The catalyst has utility in preparing unsaturated aldehydes and acids from propylene and isobutylene in a single reactor.
