Quaternary alkyl ammonium hypochlorite solution, method of producing the same, and method for processing semiconductor wafers
Provided is a method of producing a quaternary alkyl ammonium hypochlorite solution with an excellent storage stability. Specifically, provided is a method of producing a quaternary alkyl ammonium hypochlorite solution, the method including: a preparation step in which a quaternary alkyl ammonium hydroxide solution is prepared and the concentration of amines in the quaternary alkyl ammonium hydroxide solution is set to 20 ppm by mass or less; and a reaction step in which the quaternary alkyl ammonium hydroxide solution is brought into contact with chlorine gas, wherein the concentration of carbon dioxide of a gas phase in the reaction step is 100 ppm by volume or less and the pH of a liquid phase in the reaction step is 10.5 or more.
Propenylamines and methods of making and using same
A composition includes a perfluorinated propenylamine represented by the following general formula (1): Each occurrence of Rf1 and Rf2 is: (i) independently a linear or branched perfluoroalkyl group having 1-8 carbon atoms and optionally comprises one or more catenated heteroatoms; or (ii) bonded together to form a ring structure having 4-8 carbon atoms and that optionally comprises one or more catenated heteroatoms. At least 60 wt. % of the perfluorinated propenylamine is in the form of the E isomer, based on the total weight of the perfluorinated propenylamine in the composition. ##STR00001##
