Assignee:

BASF Aktiengesellschaft - Ludwigshafen

International Classification:

C07C027/10
C07C051/16
C07C045/50

US Classification:

5625122, 562531, 562534, 568454, 568476, 568478

Abstract:

A process for preparing hydroformylation products of propylene and for preparing acrylic acid and/or acrolein comprises a) feeding a propylene-containing feed in which from 2 to 40% by weight of propane is present and also carbon monoxide and hydrogen into a reaction zone and reacting this mixture in the presence of a hydroformylation catalyst to form hydroformylation products of propane, b) separating a stream consisting essentially of unreacted propylene and propane from the output from the reaction zone, and c) subjecting the stream consisting essentially of propylene and propane to a catalytic gas-phase oxidation in the presence of molecular oxygen to form acrylic acid and/or acrolein.

International Classification:

C07C 67/08

Abstract:

A method for preparing an aromatic di-ester includes combining an aromatic di-acid and a linear or branched C4-C13 alcohol to form a mixture. The method also includes heating the mixture from a first temperature (T1) to a second temperature (T2) without a catalyst present in the mixture. The method further includes combining a titanium catalyst with the mixture after the mixture is at the second temperature (T2). The method further includes increasing pressure from a first pressure (P1) to a second pressure (P2) after the mixture is at the second temperature (T2). The method further includes increasing the temperature of the mixture from the second temperature (T2) to a third temperature (T3) while maintaining the second pressure (P2).

International Classification:

C07C 69/82
C07C 67/08
C08K 5/12

Abstract:

A plasticizer composition is disclosed that includes di(2-ethylhexyl) terephthalate, and which is substantially free of a di-ester according to Formula I:where Ris a straight-chain or branched alkyl group having from 1 to 13 carbon atoms, and where Ris different than 2-ethylhexane. The plasticizer composition may be used in a plastisol composition, a powder coating composition, a molding composition, and various other compositions. A method of preparing an aromatic di-ester is also disclosed. The method may prepare the plasticizer composition.
