Alkylation Of Aromatic Amines With Olefins On Partially Dealuminated Zeolites
View pageUS Patent:
48763772, Oct 24, 1989
Filed:

Appl. No.:
7/171602

Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C07C 87452
US Classification:
558416
Abstract:
This invention pertains to an improved process for the alkylation of aromatic amines. The improvement resides in the use with particular aromatic amines and olefins a catalyst which is a highly acidic partially dealuminated zeolite having an increased silica to alumina molar ratio over the original zeolite and an acidity factor of at least 0. 3. The partially dealuminated zeolites are preferably exchanged with hydrogen or rare earth metal and are particularly effective for producing an alkylated aromatic amine where the alkyl group is ortho to the amine. The highly acidic partially dealuminated H-mordenite and partially dealuminated HY faujasite are very effective for the alkylation of aniline with propylene.

C07C 6705
C07C 6705
US Classification:
549326
Abstract:
Butadiene and acetic acid are reacted with a metal salt oxidant in molten salt medium to form. gamma. -vinyl-. gamma. -butyrolactone. The process includes electrolytic regeneration of the oxidant and provides a simple reaction system which permits product recovery and reactant recycle without extensive solvent handling. A high surface area reactor can be employed.

International Classification:
F25J 100
US Classification:
62625
Abstract:
The process recovers NF3 from a multicomponent fluid containing NF3, one or more components less volatile than NF3, and one or more components more volatile than NF3. The process uses a first distillation column and a second distillation column, each distillation column having a top and a bottom. The process includes the following steps: feeding the multicomponent fluid to the first distillation column at a first feed location below the top of the first distillation column; feeding a cryogenic liquid to the first or second distillation column adjacent the top of the first or second distillation column; withdrawing a mixture containing NF3 from the first distillation column; feeding the mixture to the second distillation column at a second feed location; separating NF3 from the mixture in the second distillation column; and removing a stream of NF3 from the second distillation column.

Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C07C20968
US Classification:
564409
Abstract:
A process for selectively producing ortho-alkylated aromatic amines in high selectivity relative to N-alkylated aromatic amines. The process comprises reacting an aromatic amine, having at least one hydrogen atom in a position ortho to the amine functionality, and an olefin under conditions sufficient to effect an alkylation reaction, in the presence of a zeolite catalyst which has been thermally pretreated by heating the catalyst to a temperature greater than about 500. degree. C. for a period ranging from 0. 5 to about 10 hours while sweeping an inert gas over the heated catalyst to remove water and ammonia formed during the thermal treatment, and subsequently recovering the alkylated aromatic amine.

International Classification:
B01D 5304
US Classification:
95 96
Abstract:
Nitrogen is produced by separating air in a pressure swing adsorption process using a high capacity kinetically O. sub. 2 selective material as the adsorbent. An example of such an adsorbent is a carbon molecular sieve made from coconut shell char. Such a coconut shell char having a high oxygen volumetric capacity is provided by crushing and sizing coconut shells to form granules which are then heated in flowing inert gas at a temperature ramp rate of about 2 to 12. degree. C. per minute to a peak temperature of 775 to 900. degree. C. which is then held so that the total heating time is up to 8 hours and thereafter the granular char is cooled in an inert gas atmosphere. The granular char thus produced is kinetically selective for O. sub. 2 over N. sub. 2 without further modification to narrow the openings of its micropores and has an oxygen volumetric capacity in excess of 8. 0 cc/cc at 1 atm.
