Esterification Of Phenols

View page
US Patent:
58081305, Sep 15, 1998
Filed:
Sep 17, 1996
Appl. No.:
8/714279
Inventors:
Leroy Krbechek - Santa Rosa CA
Assignee:
Henkel Corporation - Plymouth Meeting PA
International Classification:
C07C 6900
US Classification:
560130
Abstract:
Relates to the direct esterification of phenols, particularly alkyl-substituted phenols, with a carboxylic acid or anhydride, in the presence of a strong acid catalyst. Also relates to the use of the acid anhydride to drive the esterification reaction to completion, where an initial reaction mixture has been formed using the carboxylic acid. Further relates to the achievement of economies in esterification by recovering dilute aqueous acid when either the acid or anhydride is used initially, for recycling to achieve economies of acid use.

Process For Recovery Of Amino Acids From Aqueous Mixtures

View page
US Patent:
49369997, Jun 26, 1990
Filed:
Jul 1, 1988
Appl. No.:
7/214564
Inventors:
Phillip L. Mattison - New Brighton MN
Ronald P. Wirth - Minneapolis MN
Michael J. Virnig - Fridley MN
LeRoy Krbechek - Golden Valley MN
Assignee:
Henkel Corporation - Ambler PA
International Classification:
B01D 6116
US Classification:
210639
Abstract:
Disclosed is a process for recovery of amino acids from aqueous mixtures. In particular, it relates to a treatment of said amino acid containing aqueous mixture prior to extraction of the amino acid with a water immiscible organic solution containing a water insoluble extractant for said amino acid. The overall process of the invention which includes the pretreatment and extraction, also includes optional methods of recovering said extracted amino acid from the water immiscible organic solution. Accordingly, the invention also relates to a process for recovery of the amino acid by stripping of the amino acid from the organic solution and precipitation of the amino acid.

Steroid Production

View page
US Patent:
42553458, Mar 10, 1981
Filed:
Feb 19, 1980
Appl. No.:
6/122397
Inventors:
Leroy O. Krbechek - Minneapolis MN
Assignee:
Henkel Corporation - Minneapolis MN
International Classification:
C07J 900
US Classification:
2603971
Abstract:
The present invention discusses the production of useful steroids through starting with a steroid which has an acid side chain attached to the steroid ring structure. The present invention also describes and claims several novel compounds obtained through the described process.

Esterification Process

View page
US Patent:
53027485, Apr 12, 1994
Filed:
Feb 11, 1993
Appl. No.:
8/016377
Inventors:
Leroy O. Krbechek - Santa Rosa CA
Assignee:
Henkel Corporation - Plymouth Meeting PA
International Classification:
C07C 6952
US Classification:
560265
Abstract:
An improved process for preparing esters of an alcohol and a carboxylic acid employing sulfuric acid in an amount effective to both catalyze the reaction and to remove or immobilize the water of reaction whereby an ester is provided in increased yield and purity. Esters of long chain acids are useful for the preparation of diketones which find utility as metal extractants.

Preparation Of 22-Steroid Acetals

View page
US Patent:
42017165, May 6, 1980
Filed:
Mar 27, 1978
Appl. No.:
5/890102
Inventors:
Leroy O. Krbechek - Golden Valley MN
Assignee:
Henkel Corporation - Minneapolis MN
International Classification:
C07J 700
C07J 900
US Classification:
2603974
Abstract:
The present invention relates to the preparation and recovery of C. sub. 21 steroid acetals. The present invention also discusses the recovery of a 20 steroid carboxaldehyde from a mixture containing a 3,20 dione steroid.

Preparation Of Steroidal Carbamates

View page
US Patent:
42527317, Feb 24, 1981
Filed:
Feb 19, 1980
Appl. No.:
6/122395
Inventors:
Leroy O. Krbechek - Minneapolis MN
Assignee:
Henkel Corporation - Minneapolis MN
International Classification:
C07J 100
US Classification:
2603973
Abstract:
The present invention describes a process for converting the amides of certain steroids to the corresponding carbamates of the steroid.

Reoximation Of Metal Extraction Circuit Organics

View page
US Patent:
59937572, Nov 30, 1999
Filed:
Feb 20, 1998
Appl. No.:
9/027063
Inventors:
Michael J. Virnig - Tucson AZ
Leroy Krbechek - Santa Rosa CA
Mary Casey - Bishopstown, IE
Assignee:
Henkel Corporation - Gulph Mills PA
International Classification:
C22B 1500
C22B 2300
C22B 1900
US Classification:
423 24
Abstract:
A process for purifying a degraded oxime metal extractant organic phase from a metal extraction circuit wherein a degraded oxime metal extractant organic phase comprised of an oxime metal extractant, and aldehyde or ketone degradates in a water immiscible hydrocarbon solvent is reoximated thereby restoring the oxime extractant organic phase for further extraction in the metal extraction circuit. Optionally the degraded organic phase may be purified by distillation prior to reoximation. The distillation is carried out in a wiped film evaporator at temperatures above 180. degree. C. up to about 250. degree. C. at a pressure from about 0. 5 mm Hg or lower up to about 10 mm Hg and the reoximation is carried out with hydroxylamine in the presence of a weak organic carboxylic acid as a phase transfer catalyst and in the presence of an alkali metal or alkaline earth metal hydroxide or carbonate, preferably sodium carbonate.

Oximation Process

US Patent:
53006895, Apr 5, 1994
Filed:
Mar 20, 1992
Appl. No.:
7/854522
Inventors:
Leroy O. Krbechek - Santa Rosa CA
Mary I. Casey - Bishopstown, IE
Assignee:
Henkel Corporation - Ambler PA
International Classification:
C07C24908
US Classification:
564259
Abstract:
An improved process for oximation of carbonyl compounds, such as ketones and aldehydes by oximation with hydroxylamine including oximation processes carried out in the presence of a catalytic amount of an acid phase transfer catalyst, such as 2-ethylhexanoic acid, and/or the presence of an alkali metal or alkaline earth metal catalyst. The resulting oximes are useful as metal extractants.
