6962964, Nov 8, 2005
Filed:
Feb 6, 2003
Appl. No.:
10/359450
Inventors:
Michael Ulman - Alburtis PA, US
Gamini Ananda Vedage - Bethlehem PA, US
David Alan Dubowik - Allentown PA, US
Stephen Michael Boyce - Bath PA, US
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C08G059/00
US Classification:
528122, 525406, 528123, 528124, 528407, 564305, 564306, 564315, 564330, 564448, 564451, 564457, 564462
Abstract:
This invention relates to improved polyepoxide resins cured with a mixture of methylene bridged poly(cycloaliphatic-aromatic)amines and a process for preparing such polyepoxide resins as well as to the methylene bridged poly(cycloaliphatic-aromatic)amine compositions and a method of making them. The improvement resides in using a curative (herein referred to as “Heavy MPCA”) comprised of the partially hydrogenated condensation product of formaldehyde and aniline or methyl substituted aniline containing a substantial amount (from 35 to 85% by weight, preferably 40 to 60% by weight) of oligomers in the form of 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 and 15 aniline or methyl substituted aniline derivatives.

Hydrogenation Of Methylenedianiline

View page
US Patent:
6998507, Feb 14, 2006
Filed:
Aug 24, 2004
Appl. No.:
10/925105
Inventors:
Hao Ding - Macungie PA, US
Anthony Rocco Cartolano - Orefield PA, US
Vipul P. Dholakia - Macungie PA, US
Gamini Ananda Vedage - Bethlehem PA, US
Assignee:
Air Products and Chemicals, Inc. - Allentown PA
International Classification:
C07C 209/77
US Classification:
564451
Abstract:
The invention is directed to an improvement in a catalytic process for the ring hydrogenation of a methylenedianiline feedstock, including crude methylenedianiline. One component of the improvement is a pretreatment process which resides in passing the crude methylenedianiline feedstock over a ruthenium catalyst carried on a fixed bed support, cooling without venting, and then hydrogenation of the pretreated crude methylenedianiline feedstock over a rhodium catalyst or a mixed Rh/Ru catalyst carried on a monolith support and carrying out the ring hydrogenation in a batch reaction. Another component in the improvement is the employment of a catalyst comprised of rhodium and ruthenium carried on a monolith support.
