6417412, Jul 9, 2002
Filed:
Dec 3, 2001
Appl. No.:
10/005110
Inventors:
Andrew P. Kahn - Eagleville PA
Lawrence J. Karas - West Chester PA
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07C 2134
US Classification:
568917, 568913
Abstract:
The present invention relates to purification of a tertiary butyl alcohol process stream by contact in the liquid phase with a large pore zeolite such as 13X in the sodium form.

Purification Of Alkylene Carbonate

US Patent:
6586605, Jul 1, 2003
Filed:
Jan 8, 2003
Appl. No.:
10/339748
Inventors:
Andrew P. Kahn - Eagleville PA
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07D31736
US Classification:
549230, 203 29
Abstract:
The invention is a method to purify an alkylene carbonate such as propylene carbonate by contact with at least two solid adsorbents comprising carbon and an inorganic silicon or aluminum oxide. The purification method successfully improves color and color stability while also reducing the amount of catalyst impurity contained in the alkylene carbonate.

Alkylene Carbonate Purification

US Patent:
6696579, Feb 24, 2004
Filed:

Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07D31700
US Classification:
549449
Abstract:
An alkylene carbonate such as propylene carbonate is contacted with an alumina or silica solid adsorbent having a surface area of 50-400 m /g such as basic alumina to remove impurities therefrom and improve color and color stability.

Purification Of Tertiary Butyl Alcohol

US Patent:
6770790, Aug 3, 2004
Filed:
Oct 17, 2003
Appl. No.:
10/688410
Inventors:
Xiangmin Li - West Chester PA
Lawrence M. Candela - Havertown PA
Yuan-Zhang Han - West Chester PA
Andrew P. Kahn - Eagleville PA
Assignee:
ARCO Chemical Technology, L.P. - Greenville DE
International Classification:

US Classification:
568917, 568913, 568914, 568915, 568916, 568918
Abstract:
The invention is a method to purify tertiary butyl alcohol by contact with at least two solid adsorbents comprising aluminum oxide and a large pore zeolite such as zeolite X. The purification method successfully improves product quality and reduces the amount of impurities in the tertiary butyl alcohol.

Production Of N-Vinyl Pyrrolidone

US Patent:
6906200, Jun 14, 2005
Filed:
Oct 1, 2002
Appl. No.:
10/261357
Inventors:
Andrew P. Kahn - Eagleville PA, US
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07D207/267
C07D207/26
US Classification:
548552, 548543, 548551
Abstract:
N-vinyl pyrrolidone is produced by dehydration of N-hydroxyethyl pyrrolidone in the presence of an amorphous mixed oxide catalyst such as an amorphous Ca/Zn oxide catalyst.

Process For Making N-Vinyl-2-Pyrrolidone

US Patent:
6982337, Jan 3, 2006
Filed:
Jul 28, 2004
Appl. No.:
10/900963
Inventors:
Andrew P. Kahn - Eagleville PA, US
Assignee:
Lyondell Chemical Technology, L.P. - Greenville DE
International Classification:
C07D 207/267
A61K 31/4015
US Classification:
548408
Abstract:
A process for making N-vinyl-2-pyrrolidone (NVP) is disclosed. The process comprises dehydrating N-(2-hydroxyethyl)-2-pyrrolidone (HEP) in the presence of a catalyst and added water. Adding an effective amount of water into the dehydration process reduces the amount of N-ethyl-2-pyrrolidone (NEP) formed compared with the amount produced in the absence of the added water. Adding water can also sustain high conversions of HEP, minimize heavies formation, and improve selectivity to NVP. The process provides high-purity NVP and avoids a costly crystallization step.

Diisobutylene Process

US Patent:
7012167, Mar 14, 2006
Filed:
Oct 8, 2003
Appl. No.:
10/681395
Inventors:
Andrew P. Kahn - Eagleville PA, US
Assignee:
Lyondell Chemical Technology, L.P. - Greenville DE
International Classification:
C07C 1/00
C07C 2/24
US Classification:
585324, 585329, 585515, 585526
Abstract:
This invention is a process for producing diisobutylene from isobutylene. The process comprises first oligomerizing isobutylene to diisobutylene using a sulfonic acid-type ion exchange resin. The oligomerization step is followed by contacting the diisobutylene product with an adsorbent to remove sulfur impurities produced during the oligomerization step. The adsorbent is a large pore zeolite such as zeolite X and zeolite Y. Optionally, the purified diisobutylene may be hydrogenated to isooctane using a hydrogenation catalyst.

Purification On Methyl Tertiary Butyl Ether

10/301441
Inventors:
Lawrence J. Karas - West Chester PA, US
Lawrence M. Candela - Havertown PA, US
Andrew P. Kahn - Eagleville PA, US
Assignee:
Arco Chemical Technology, L.P. - Greenville DE
International Classification:
C07C 41/36
US Classification:
568699, 568697
Abstract:
The present invention relates to purification of an MTBE process stream by contact in the liquid phase with a large pore zeolite such as 13X or Zeolite Y.
