Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C05C 900
C05C 700
C05B 1500
C05B 700

US Classification:

71 28

Abstract:

Solids having a tendency to cake are treated with distillation heavies that are liquid at about 60. degree. C. or less and are obtained from production of a ketone having the formula: R. dbd. O, wherein R is substituted or unsubstituted, branched, straight chain or cyclic, C. sub. 4 to C. sub. 18. The solids so treated have a reduced tendency to cake.

Teresa C. Webb - Leicester NC

Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C09K 322

US Classification:

252384

Abstract:

Solid materials are treated with a blend of water or solvents and distillation bottoms obtained from production of an alcohol having the formula: R2--R1--OH, wherein R1 is substituted or unsubstituted, branched, straight chain, or cyclic C. sub. 4 to C. sub. 12 and R2 is OH or H.

US Patent:

Filed:

Dec 23, 1996

Appl. No.:

8/771545

Inventors:

Andrew J. McNabb - Lake Jackson TX
Rebecca E. Phillips - Lake Jackson TX

Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C07C 2726
C07C 3508

US Classification:

568856

Abstract:

A process for increasing the amount of isolatable products in a by-product stream generated in the production of 1,6 hexanediol includes combining the by-product stream with water to form a combination of the water and the by-product stream; and reacting the combination at a temperature between about 250. degree. C. to about 400. degree. C. at a pressure from about 1,000 psig to about 3,000 psig to form one or more reaction products.

Filed:

Nov 9, 1999

Appl. No.:

9/436351

Inventors:

Andrew J. McNabb - Lake Jackson TX
Deirdre R. Williams - Lake Jackson TX

Assignee:

BASF Corporation - Mt. Olive NJ

International Classification:

C07C 4529

US Classification:

568366

Abstract:

Organic by-products having higher boiling points than cyclohexanone (usually obtained from the bottoms of a distillation operation to separate cyclohexanone from other reaction products during cyclohexanone production) can be converted to recoverable cyclohexanone and cyclohexanol using a catalyst having high aluminum oxide concentrations. The preferred catalyst is one which has an aluminum oxide (Al. sub. 2 O. sub. 3) content of at least about 95 wt. %, and more preferably greater than about 99 wt. %.
