20100012901HYDROLYZED NITRILOTRIACETONITRILE COMPOSITIONS, NITRILOTRIACETONITRILE HYDROLYSIS FORMULATIONS AND METHODS FOR MAKING AND USING SAME - Hydrolyzed nitrilotriacetonitrile compositions are disclosed prepared by a method characterized by a one-shot addition of an amount of nitrilotriacetonitrile to a solution containing an acid catalyst, where the reaction is complete in a time period of less than an hour. The method is also characterized by adjusting the pH of the reaction mixture to a pH of at least 8. The method is also characterized by oxidatively removing free cyanide to a desired low level through the addition of an oxidizing agent the produces environmentally benign by-products to the crude hydrolyzed NTAN to form hydrolyzed NTAN compositions having minimized, negligible, or substantially no free cyanide levels.01-21-2010
20090212261Anticaking agent for iron and steel slag - An anticaking agent for an iron and steel slag contains (A) at least one member selected from the group consisting of a phosphonic acid derivative and a salt thereof and (B) at least one member selected from the group consisting of an aliphatic hydroxycarboxylic acid and a salt thereof, at a mixing ratio (A)/(B) of the at least one member selected from the group consisting of a phosphonic acid derivative and a salt thereof (A) to the at least one member selected from the group consisting of an aliphatic hydroxycarboxylic acid and a salt thereof (B) of from 95/5 to 5/95 by mass, and the anticaking agent for an iron and steel slag may further contain (C) a sugar alcohol, thereby providing further high synergistic effect on anticaking capability.08-27-2009
20100025635METHOD OF IMPROVING FLOWABILITY OF ADIPIC ACID - A method of improving flowability of adipic acid includes adding to the adipic acid at a relatively low temperature a flowability improving agent, such as an acyclic saturated monobasic acid containing 10 to 22 carbon atoms or an acyclic saturated dibasic acid containing 10 to 14 carbon atoms.02-04-2010
20090159851PROTECTIVE COMPOSITION - The present invention relates to a process for preparing a protective composition, said process comprising mixing an oil and a wax at a temperature above the wax transition temperature to form a homogeneous composition, and quenching the homogeneous composition to ambient temperature at a rate of at least 15° C. per second. The invention further relates to a process for protecting a metal object against corrosion, wherein the metal object is provided with a layer of the protective composition according to the invention.06-25-2009
20130099169METHODS AND COMPOSITIONS FOR PASSIVATING HEAT EXCHANGER SYSTEMS - A process for extending the life of coolant fluids by passivating surfaces of components and parts in heat exchanger systems that employ coolants for heat transfer. In the method, heat exchanger parts with metal surfaces which chemically and detrimentally interact with additives in coolant fluids in the heat exchanger system are treated by contacting the metal surfaces with a phosphate-containing solution for the phosphate-containing solution to passivate the metal surface for subsequent contact with the coolant fluids.04-25-2013

20090001321AQUEOUS SOLUTION OF POLYMER HAVING UPPER CRITICAL SOLUTION TEMPERATURE, AQUEOUS DISPERSION OF PARTICLE MODIFIED WITH THE POLYMER AND METHOD OF STORING THE SAME - It is intended to provide an aqueous solution of a thermoresponsive polymer and an aqueous dispersion of a thermoresponsive particle, which show an upper critical solution temperature (UCST) and are capable of maintaining a dissolved state and a dispersed state, respectively, even if they are stored for a long period of time at a temperature at which a ligand such as an antibody or an antigen is not inactivated. A UCST lowering agent is incorporated in a predetermined amount in an aqueous solution of a thermoresponsive polymer which shows a UCST in a state of containing water or an aqueous dispersion of a thermoresponsive particle containing the polymer, thereby lowering the UCST of the aqueous solution or aqueous dispersion to less than the storage temperature, and the resulting aqueous solution or aqueous dispersion is stored.01-01-2009
20120205589Process for the Production of Naphthenic Process Oils by Hydrogenation - The object of the invention is a method for producing naphthenic process oils that have a high content of naphthenic carbon atoms of 20-60 wt % and a low content of polycyclic aromatics of less than 3 wt %, determined in accordance with IP 346, by the hydrogenation of a process oil educt that has a high content of polycyclic aromatics. The method in accordance with the invention enables secondary extracts, such as are formed in the production of label-free process oils, even in a mixture with primary extracts, to be utilized in an economically meaningful way. The resulting process oils are likewise label-free, so that the use of PCA-containing process oils can be reduced and less of these substances will get into the environment. Through this the environment and in particular health are less stressed. In addition, the starting substances in this way can lead to a different use and no longer have to be added to heating oil. By avoiding heating oil, CO08-16-2012
