US Patent:

44203764, Dec 13, 1983

Filed:

Aug 23, 1982

Appl. No.:

6/410346

Inventors:

Ward J. Burkholder - Gonzales LA

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

B01D 338
B01D 340
C07C 3908

US Classification:

203 29

Abstract:

An improved process for recovering high purity resorcinol produced by the rearrangement of m-diisopropylbenzene dihydroperoxide in which the rearranged product mixture is neutralized, the neutralized mixture being filtered, the filtrate being admixed with toluene, the acetone being removed by distillation and the acetone-free rearranged product/toluene mixture being steam distilled to provide an aqueous resorcinol containing phase from which the resorcinol is recovered.

Filed:

Jul 19, 1978

Appl. No.:

5/926139

Inventors:

Ward J. Burkholder - Baton Rouge LA

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

C07G179035

US Classification:

568576

Abstract:

Separation of diisopropylbenzene dihydroperoxide from a diisopropylbenzene oxidation reaction mixture by treating the reaction mixture with concentrated alkali metal hydroxide and recovering the alkali metal salt of diisopropylbenzene dihydroperoxide in high purity and good yield, and subsequently converting the salt to diisopropylbenzene dihydroperoxide.

Appl. No.:

5/433393

Inventors:

Ward J. Burkholder - Baton Rouge LA

Assignee:

The Goodyear Tire & Rubber Company - Akron OH

International Classification:

C07C 3708

US Classification:

260621C

Abstract:

A portion of a recycle stream obtained from the reaction mixture resulting from the oxidation of an aryl tertiary alkane and containing primarily aralkyl tertiary monohydroperoxide, unreacted aryl tertiary alkane, a minor amount of aralkyl tertiary polyhydroperoxide and other by-products is separated to obtain a fraction containing substantially all of the polyhydroperoxide and at least some of the by-products, the fraction then being introduced into a rearrangement zone to convert at least a portion of the polyhydroperoxide to the corresponding polyphenol.
