Abstract: An oil absorbing article which includes an oil absorbent material which is stable against melting at a temperature of at least about 100° F. in an aqueous environment; a receptacle for holding the oil absorbent material having a porous material which is stable against melting at a temperature of at least about 100° F. in an aqueous environment and which permits the passage of water and oil components through the receptacle; and a flexible handle attached to the receptacle for hanging the oil absorbent article in the aqueous environment. Also, a method for using the oil absorbing article by placing the article in an aqueous environment having a temperature of at least about 100° F. and which is contaminated with oil components for a period of time sufficient to remove at least a portion of the oil components.

Abstract: The invention pertains to a method for fluorometrically monitoring a Clean-In-Place (“CIP”) system and for fluorometrically monitoring the dosage of chemical added to the CIP system. Monitoring of the said CIP system can be based upon fluormetrically monitoring the fluorescent tracer, chemical or both, which are added to the CIP system.

Abstract: A process for deuterium isotopic enrichment (suitable for use in heavy water production) by amine-hydrogen exchange in which the exchange catalyst comprises a mixture of alkyl amides of two metals selected from the group consisting of the alkali metals. Catalyst mixtures comprising at least one of the alkali amides of lithium and potassium are preferred. At least one of the following benefits are obtained:decreased hydride formation, decreased thermal decomposition of alkyl amide, increased catalyst solubility in the amine phase, and increased exchange efficiency.
