Patent number: 8309502Abstract: Compositions and methods useful for the removal of organic substances from substrates, for example, electronic device substrates such as microelectronic wafers or flat panel displays, are provided. A method is presented which applies a minimum volume of the composition as a coating to the inorganic substrate whereby sufficient heat is added and immediately rinsed with water to achieve complete removal. These compositions and methods are particularly suitable for removing and completely dissolving photoresists of the positive and negative varieties as well as thermoset polymers from electronic devices.Type: GrantFiled: March 2, 2010Date of Patent: November 13, 2012Assignee: Eastman Chemical CompanyInventors: Michael Wayne Quillen, Dale Edward O'Dell, Zachary Philip Lee, John Cleaon Moore, Edward Enns McEntire

Patent number: 8309677Abstract: A system for processing large quantities of a reaction medium while maintaining the reaction medium in sheets. The system includes a reactor having a plurality of vertically-spaced downwardly-sloped trays over which the reaction medium flows while it is subjected to reaction conditions. The slope of the trays increases downwardly to accommodate for the increased viscosity of the reaction medium while the reaction medium flows downwardly through the reactor. An upper portion of the trays have a uni-directional configuration, while a lower portion of the trays have a bi-directional configuration. Further, the orientation of flow across the uni-directional trays is rotated by 90 degrees in at least one location as the reaction medium flows down the uni-directional trays.Type: GrantFiled: January 14, 2010Date of Patent: November 13, 2012Assignee: Eastman Chemical CompanyInventors: Thomas Lloyd Yount, Larry Cate Windes, Bruce Roger DeBruin

Patent number: 8058355Abstract: The present invention provides solvent- and water-based primer compositions that include at least one chlorinated carboxylated polyolefin that has been modified with one or more polyfunctional alcohols. The chlorinated carboxylated polyolefins are obtained by the reaction of polyolefins with at least one of unsaturated carboxylic esters, unsaturated carboxylic acids, unsaturated carboxylic anhydrides, acrylic monomers, and mixtures thereof then chlorinated. The chlorinated carboxylated polyolefins are then further modified by reaction with one or more polyfunctional alcohols. These polyfunctional alcohol-modified chlorinated carboxylated polyolefins may also contain pendant carboxyl groups, which have the propensity to form hydrophilic salts with amines or inorganic bases, thereby rendering the polyfunctional alcohol-modified chlorinated carboxylated polyolefins water-dispersible.Type: GrantFiled: August 31, 2005Date of Patent: November 15, 2011Assignee: Eastman Chemical CompanyInventors: Robert Lee Eagan, Kevin Alan Williams, Allen Morgan Cheek

Patent number: 7901636Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.Type: GrantFiled: February 25, 2009Date of Patent: March 8, 2011Assignee: Eastman Chemical CompanyInventors: Alan George Wonders, Robert Lin, Marcel de Vreede, Lee Reynolds Partin

Patent number: 7892498Abstract: A polyester production system employing a vertically elongated esterification reactor. The esterification reactor of the present invention is an improvement over conventional CSTR esterification reactors because, for example, in one embodiment, the reactor requires little or no mechanical agitation. Further, in one embodiment, the positioning of the inlets and outlets of the reactor provides improved operational performance and flexibility over CSTRs of the prior art.Type: GrantFiled: March 8, 2007Date of Patent: February 22, 2011Assignee: Eastman Chemical CompanyInventor: Bruce Roger DeBruin

Patent number: 7863407Abstract: A process for producing terephthalic acid in a TPA facility, polyethylene terephthalate in a PET facility, and containers in a forming facility in which the distance between the TPA facility and the forming facility is less than about 10 miles. There is also described a process for transporting a wet mixture of TPA particles via a convey system to a PET facility. In contrast to traditional processing schemes, the processing steps can be located proximate to each other and can be integrated to eliminate certain intermediate processing steps such as, for example, purification, heating, cooling, and drying.Type: GrantFiled: July 11, 2008Date of Patent: January 4, 2011Assignee: Eastman Chemical CompanyInventors: Bruce Roger DeBruin, Allan R.

Patent number: 7863405Abstract: In one embodiment, there is provided a process comprising introducing polyester polymer particles containing residual acetaldehyde into a vessel at a temperature within a range of 130° C. to 195° C. to form a bed of particles within the vessel, flowing a gas through at least a portion of the particle bed, and withdrawing finished particles from the vessel having a reduced amount of residual acetaldehyde. In this process, it is not necessary to introduce a hot flow of gas at high flow rates otherwise required to heat up cool particles to a temperature sufficient to strip acetaldehyde. Rather, this process provides a benefit in that, if desired, gas introduced into the vessel at low flow rates and low temperatures can nevertheless effectively strip acetaldehyde in a reasonable time because the hot particles quickly heat a the gas to the particle temperature.Type: GrantFiled: December 21, 2004Date of Patent: January 4, 2011Assignee: Eastman Chemical CompanyInventors: Rodney Scott Armentrout, Frederick Leslie Colhoun, Michael Paul Ekart, Bruce Roger DeBruin

Patent number: 7459113Abstract: There is now provided a polyester polymer particle having an It.V., a surface, and a center, wherein the It.V. at the surface of the particle is less than 0.25 dL/g higher than the It.V. at the center of the particle. The polyester polymer particle is desirably crystalline to prevent the particles from sticking to each other while drying, and desirably contains less than 10 ppm acetaldehyde. A polyester container, preferably a preform or beverage bottle, is made by feeding crystallized polyester particles having an It.V. of at least 0.70 dL/g to an extrusion zone, melting the particles in the extrusion zone to form a molten polyester polymer composition, and forming a sheet or a molded part from extruded molten polyester polymer, wherein at least a portion of the polyester particles have an It.V. at their surface which does not vary from their It.V. at their center by more than 0.25 dL/g, and the particles have not been solid state polymerized. Such polyester compositions have an It.V.Type: GrantFiled: March 8, 2004Date of Patent: December 2, 2008Assignee: Eastman Chemical CompanyInventors: Frederick Leslie Colhoun, Michael Paul Ekart, Mary Therese Jernigan, Stephen Weinhold
