Abstract: Systems and methods for detecting efforts to thwart discovery of a thing, the methods including: using a detector system in an area to detect a reaction product of a thing with descenter; producing with the detector system a detected reaction product level; comparing the detected reaction product level to a normal level of the reaction product in the area; and upon determining that the detected reaction product level is different from the normal level, providing an indication of possible presence of the thing based on said different level.

Abstract: A process for the removal of primary and secondary amine and alkanolamine impurities from aqueous tertiary amine and alkanolamine solutions without affecting the tertiary amine and/or alkanolamine by treating these solutions with a monoaldehyde or dialdehyde has been described.

Abstract: Alkanolamines of the formula R—NHCH2CH(OH)CH2CH3  (I) or mixtures thereof wherein R is H, —CH2CH(OH)CH2CH3, an alkyl group having from 1 to 6 carbon atoms, an aryl group having from 6 to 12 carbon atoms, an aralkyl group having from 6 to 12 carbon atoms, or a cycloalkyl group having from 3 to 6 carbon atoms in combination with a tertiary alkano/amine are effective in the removal of acidic gases from a fluid stream containing same and show superior degradation properties as compared to alkanolamines conventionally used in the gas purification applications.

Abstract: Aqueous compositions comprising a mixture of a tertiary alkanolamine and a primary alkanolamine of the formulaR--CH(NH.sub.2)--CH.sub.2 --OH (I)or mixtures thereof wherein R is H, or an alkyl group having from 1 to 8 are effective in the removal of acidic gases from a fluid stream containing same and show superior degradation properties as well as unexpectedly low degradation, corrosivity and metals solubility properties.

Abstract: A process is disclosed for removing aromatics, and volatile organic hydrocarbons from a gaseous fluid stream including passing the fluid stream in contact with a dehydrating composition comprising a glycol selected from triethylene glycol, ethylene glycol, diethylene glycol, or mixtures thereof and a hydrocarbon solubility depressant. The dehydrating composition may also contain a dissolved salt including at least one alkali metal carboxylate, an ammonium carboxylate, an alkali metal halide, an ammonium halide, or a mixtures thereof.

Abstract: A process is disclosed for the neutralization of amine or alkanolamine heat stable salts with aqueous KOH or with alkali metal base, such as potassium hydroxide, sodium hydroxide, sodium carbonate, potassium carbonate, sodium bicarbonate or potassium bicarbonate formulated with amines or alkanolamines. The process results in less solid formation than commonly used alkali metal bases such as aqueous sodium hydroxide or aqueous potassium carbonate.

Abstract: A process is disclosed for producing a substituted ethylenediamine, the process comprising reacting an oxazolidinone with a secondary amine or an alkanolamine. The process includes, in one aspect, reacting precursors of the oxazolidinone in situ.

Abstract: Polyesters are prepared from dihydroxyl-containing compounds and di-carboxylic acids or anhydrides or lower alkyl esters thereof in the presence of a combination of tin catalysts comprising (1) at least one organotin salt of a carboxylic acid, and (2) either (a) at least one organotin oxide, or (b) at least one organostannoic acid, or (c) a combination of (a) and (b). The polyesters prepared by this process are useful in coating, adhesive, fiber and molding applications.
