Separation Of 3-Methyl-2-Butanone From Formic Acid By Extractive Distillation
US Patent:
4840707, Jun 20, 1989
Filed:
Dec 30, 1988
Appl. No.:
7/291961
Inventors:
Lloyd Berg - Bozeman MT
Richard R. Rall - Bozeman MT
Richard R. Rall - Bozeman MT
International Classification:
B01D 340, C07C 4583, C07C 5302
US Classification:
203 51
Abstract:
3-Methyl-2-butanone cannot be removed from 3-methyl-2-butanone and formic acid mixtures by distillation because of the presence of the maximum azeotrope between 3-methyl-2-butanone and formic acid. 3-Methyl-2-butanone can be readily removed from 3-methyl-2-butanone - formic acid mixtures by extractive distillation in which the extractive agent is dimethylacetamide, dimethylformamide or these with certain high boiling organic compounds.
Separation Of 2-Methyl-1-Propanol From 1-Butanol By Extractive Distillation
US Patent:
5723024, Mar 3, 1998
Filed:
Aug 26, 1996
Appl. No.:
8/701781
Inventors:
Lloyd Berg - Bozeman MT
International Classification:
B01D 340, C07C 2984
US Classification:
203 57
Abstract:
2-Methyl-1-propanol is difficult to separate from 1-butanol by conventional distillation or rectification because of the proximity of their boiling points. 2-Methyl-1-propanol can be readily separated from 1-butanol by extractive distillation. Effective agents are ethyl benzene, amyl acetate and propoxypropanol.
Separation Of Ethylbenzene From Para- And Meta-Xylenes By Extractive Distillation
US Patent:
4292142, Sep 29, 1981
Filed:
Jan 12, 1981
Appl. No.:
6/224175
Inventors:
Lloyd Berg - Bozeman MT
Assignee:
International Synthetic Rubber Co., Ltd. - Southampton
International Classification:
F01D 340
US Classification:
203 51
Abstract:
Ethylbenzene and para-xylene and/or meta-xylene are difficult to separate by distillation because they boil only 2. 3 C. degree. and 3. 1 C. degree. apart. Ethylbenzene can be readily separated from the xylenes by using extractive distillation in which the extractive distillation agent is a mixture of oxygen-containing organic compounds boiling higher than the xylenes. The mixture typically includes phthalic anhydride and maleic anhydride with or without a solvent.
Separation Of 1-Butanol From 2-Pentanol By Extractive Distillation
US Patent:
5709781, Jan 20, 1998
Filed:
Feb 11, 1997
Appl. No.:
8/799701
Inventors:
Lloyd Berg - Bozeman MT
International Classification:
B01D 340, C07C 2984
US Classification:
203 57
Abstract:
1-Butanol is difficult to separate from 2-pentanol by conventional distillation or rectification because of the proximity of their boiling points. 1-Butanol can be easily separated from 2-pentanol by extractive distillation. Effective agents are anisole, ethyl nonanate and butyl ether.
Dehydration Of Formic Acid By Extractive Distillation
US Patent:
5173156, Dec 22, 1992
Filed:
Dec 9, 1991
Appl. No.:
7/803509
Inventors:
Lloyd Berg - Bozeman MT
Kraig M. Wendt - Bozeman MT
Rudolph J. Szabados - Bozeman MT
Kraig M. Wendt - Bozeman MT
Rudolph J. Szabados - Bozeman MT
International Classification:
B01D 340, C07C 5302
US Classification:
203 15
Abstract:
Formic acid cannot be completely removed from formic acid--water mixtures by distillation because of the presence of the maximum azeotrope. Formic acid can be readily removed from mixtures containing it and water by using extractive distillation in which the extractive distillation agent is cyclohexanone, isophorone or a mixture of these with certain organic compounds. Typical examples of effective agents are cyclohexanone; isophorone; cyclohexanone and neodecanoic acid; isophorone and diisobutyl ketone.
Recovery Of Glycerine From Sorbitol By Azeotropic Distillation
US Patent:
5190622, Mar 2, 1993
Filed:
Nov 14, 1991
Appl. No.:
7/792155
Inventors:
Lloyd Berg - Bozeman MT
International Classification:
B01D 336, C07C 2982
US Classification:
203 60
Abstract:
Glycerine cannot be easily separated from sorbitol by atmospheric or reduced pressure distillation because of their high boiling points. Glycerine can be readily separated from sorbitol by azeotropic distillation. Typical effective agents are biphenyl, benzyl benzoate and dimethyl phthalate.
Separation Of Isopropyl Ether From Isopropanol And Water By Extractive Distillation
US Patent:
4566948, Jan 28, 1986
Filed:
Dec 20, 1984
Appl. No.:
6/684367
Inventors:
Lloyd Berg - Bozeman MT
International Classification:
B01D 340
US Classification:
203 51
Abstract:
Isopropyl ether cannot be completely removed from isopropyl ether-isopropanol-water mixtures by distillation because of the presence of the minimum ternary azeotrope. Isopropyl ether can be readily removed from mixtures containing it, isopropanol and water by using extractive distillation in which the extractive distillation agent is dimethylsulfoxide with or without a mixture of higher boiling oxygenated and/or nitrogenous organic compounds. Typical examples are dimethylsulfoxide; dimethylsulfoxide and ethylene glycol; dimethylsulfoxide, dimethylformamide and 1,4-butanediol.
Separation Of 9,11-Diene C18 Fatty Acid From 10,12-Diene C18 Fatty Acid By Azeotropic Distillation

9/363882
Inventors:
Lloyd Berg - Bozeman MT
International Classification:
B01D 336, C07C 5146
US Classification:
203 57
Abstract:
9,11- Diene C18 fatty acid cannot be separated from 10,12-Diene C18 fatty acid by conventional rectification because of the proximity of their boiling points. 9,11-Diene C18 fatty acid can be readily separated from 10,12-Diene fatty acid by azeotropic distillation. Effective agents are propyl formate, butyl ether, methyl pivalate and cyclopentanone.
Separation Of Formic Acid From Acetic Acid By Extractive Distillation
US Patent:
4692219, Sep 8, 1987
Filed:
Dec 3, 1986
Appl. No.:
6/937401
Inventors:
Lloyd Berg - Bozeman MT
Assignee:
Celanese Chemical Co. - Pampa TX
International Classification:
B01D 340, C07C 5302
US Classification:
203 51
Abstract:
Formic acid cannot be easily removed from acetic acid by distillation because of the closeness of their vapor pressures. Formic acid can be readily removed from acetic acid by extraction distillation. Typical extractive distillation agents are carboxylic acids in the range of hexamoic acid to neodecanoic acid with or without solvents such as methyl benzoate, acetophenone and nitrobenzene.
