Abstract: This invention relates to a process for the separation of a metal complex catalyst and any free ligand which may be present, from a homogeneous organic synthesis reaction mixture using sub-nanoporous, chemically stable membranes having discrete pores which allow organic products and by-products to pass through the membrane as permeate while retaining substantially all of the metal complex catalyst and free ligand, if any, as retentate.

Abstract: This invention relates to methods for spraying liquid compositions containing volatile solvent by using compressed fluids, such as carbon dioxide or ethane, to form solid particulates, coating powders, and catalyst materials, which can be produced with narrow particle size distributions and can be sprayed at higher solids levels, in ambient air or with heated air applied to just the spray instead of a spray chamber. Novel catalyst supports can be produced having a beneficial morphology such as for olefin catalysis. Drier water-borne coatings can be applied to substrates by using compressed fluids to spray water-borne coating compositions having conventional water levels, thereby reducing runs and sags and shortening dry times.

Abstract: This invention pertains to novel higher solids conductive coating compositions which can be applied by spray and other atomization methods. More particularly, it pertains to novel higher solids conductive coating compositions capable of application by electrostatic atomization methods. While there are many applications in which conductive coatings are useful, the invention is particularly useful for the manufacture of adhesion promoting primer compositions which have higher solids and can be applied by electrostatic atomization methods. The key components of the present invention are:(i) a conductive pigment,(ii) a non-conductive polymeric binder, and(iii) a solvent selected for its ability:(a) to form a stable non-conductive dispersion of a conductive pigment when subjected to an electrostatic potential of 20000+ volts,(b) to provide for a higher solids liquid coatings composition thereby reducing the volatile organic emissions (VOC) during application.

Abstract: Functional fluids comprising at least one compound selected from the group consisting of a glycol, a glycol ether, an ester, a hydrocarbon, and mixtures thereof and an effective amount of benzotriazole, a derivative thereof such as tolyltriazole or mixtures thereof and 1,2,4-triazole, a derivative thereof or mixtures thereof. The functional fluids exhibit increased resistance to corrosion and reduced sediment formation and are useful as brake fluids.

Abstract: The invention is directed to a method and apparatus for coating substrates by a liquid spray so as to avoid entrapment of gaseous bubbles, particularly air bubbles, in the coating and desirably to thereby obtain bubble-free coatings. More particularly, the invention involves spray applying the coating to a substrate in an atmosphere consisting of gases having appreciable solubility in the applied coating, such as carbon dioxide, such that gas bubbles that may become entrapped in the coating are removed after application by the gases dissolving into the coating and diffusing to the surface.

Abstract: A glycol-based deicer composition having ice adhesion repression properties is provided. Ice adhesion control derives from the presence of a film of the composition which is retained on the deiced surfaces and interferes with adhesion of new ice. The composition includes one or more anionic or nonionic surfactants selected to provide a spreading wetting value of 0 to about -5 degrees per centimeter.

Abstract: Method which includes passing a gas stream containing carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans and other acid gases through an aqueous alkanolamine solution to remove the carbon dioxide, hydrogen sulfide, sulfur dioxide, mercaptans, etc., from the gaseous stream. Heat-stable alkanolamine salts form in the aqueous alkanolamine solution due to the acid contaminants (other than hydrogen sulfide or carbon dioxide) removed from the gas stream. A base is added to the aqueous alkanolamine solution to convert all or part of the heat-stable alkanolamine salts into alkanolamine and simple salts. The base-treated aqueous alkanolamine solution is electrodialyzed in an electrodialysis cell containing ion exchange membranes. The purified aqueous alkanolamine solution can be used again to remove carbon dioxide, etc., from the gas stream.

Abstract: The present invention relates to improved reductive amination processes whereby monoethanolamine and ammonia are reacted in the presence of hydrogen and various reductive amination catalysts to yield high selectivity to acyclic products such as aminoethylethanolamine, while reducing the production of cyclic products such as piperazine. When the process of the present invention is carried out in the presence of reductive amination catalyst containing metals such as nickel or nickel-rhenium on transitional alumina carriers, productivity and selectivity to the desired products is increased. Alternatively, the process may be carried out in the presence of hydrotalcite-like or takovite-like catalysts which have been enhanced by the use of promoters to achieve the desired results.
