Process For Recycling Polyesters

View page
US Patent:
6472557, Oct 29, 2002
Filed:
Nov 12, 1999
Appl. No.:
09/438859
Inventors:
Michael Paul Ekart - Wassenaar, NL
David Dunlap Cornell - Kingsport TN
Damon Brian Shackelford - Johnson City TN
Donald Lee Carver - Church Hill TN
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C07C 5100
US Classification:
562483, 560 78, 560 89, 560 96
Abstract:
A process for producing high quality TPA suitable for PET feedstock material from recycled polyester. The process includes the steps of depolymerizing the polyester to form DMT; separating the DMT from secondary materials; and hydrolyzing the DMT to form TPA. In a preferred embodiment of the invention the recycled polyester is contacted with a component monomer or oligomer thereof to liquefy the polyester prior to depolymerizing the polyester.

Process For The Preparation Of Polyesters Containing 1,4-Cyclohexanedimethanol

US Patent:
7211634, May 1, 2007
Filed:
Apr 28, 2006
Appl. No.:
11/414466
Inventors:
Daniel Lee Martin - Kingsport TN, US
Joseph Franklin Knight - Kingsport TN, US
Benjamin Fredrick Barton - Kingsport TN, US
Damon Bryan Shackelford - Kingsport TN, US
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C08F 2/00
C08G 63/00
US Classification:
526 66, 528176, 528194, 528298, 528300, 528301, 528302, 528306, 528307, 528308, 5283085
Abstract:
Disclosed is a process for the preparation of high molecular weight polyesters by reacting one or more dicarboxylic acids directly with 1,4-cyclohexanedimethanol and, optionally, one or more diols. The process uses an overall diol to dicarboxylic acid molar ratio of about 0. 97 to about 1. 2 and an incremental addition of either the diacid or diol components. The process provides a shorter total reaction time and, thus, lessens the thermal degradation of polyester which may result in high color and reduced molecular weight.

US Patent:
8410317, Apr 2, 2013
Filed:
Jul 29, 2011
Appl. No.:
13/194024
Inventors:
Phillip Wayne Turner - Blountville TN, US
Steven Leroy Cook - Kingsport TN, US
Benjamin Fredrick Barton - Kingsport TN, US
Jeff Scott Howell - Jonesborough TN, US
Noah Glenn McMillan - Kingsport TN, US
Damon Bryan Shackelford - Kingsport TN, US
Brent Alan Tennant - Church Hill TN, US
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C07C 35/08
US Classification:
568822
Abstract:
Disclosed is a process for the preparation of 1,4-cyclohexanedimethanol from terephthalic acid. Terephthalic acid is esterified with (4-methylcyclohexyl)methanol and the terephthalate ester hydrogenated to 1,4-cyclohexanedimethanol in a 2-stage process. The (4-methylcyclohexyl)methanol that is formed during the hydrogenation step is recycled to the esterification reaction. After removal of the (4-methylcyclohexyl)methanol from the crude hydrogenation product, the 1,4-cyclohexanedimethanol product can be recovered and purified by a phase separation and distillation.

US Patent:
8586701, Nov 19, 2013
Filed:
Jul 3, 2007
Appl. No.:
11/773275
Inventors:
Benjamin Fredrick Barton - Kingsport TN, US
Damon Bryan Shackelford - Kingsport TN, US
Assignee:
Eastman Chemical Company - Kingsport TN
International Classification:
C08G 63/00
US Classification:
5283087, 528272, 528274, 528286, 528307, 5283086, 526 66
Abstract:
Disclosed is a process for the preparation of high molecular weight, thermoplastic copolyesters by reacting a diester composition comprising a dialkyl ester of terephthalic acid with a diol composition comprising a first diol component comprising 2,2,4,4-tetramethyl-1,3-cyclobutanediol and a second diol component comprising 1,4-cyclohexanedimethanol. The diester composition can be reacted with the first diol component to produce a polyester oligomer that can be reacted further with the second diol component to produce a modified polyester oligomer. The modified polyester oligomer can then be heated to form a copolyester. The process reduces the precipitation of poly(1,4-cyclohexylene dimethylene) terephthalate in the reaction mixture.
