  • Patent number: 8129325
    Abstract: Certain substituted phenolic compounds when used with or without 1,2-epoxides as the sole stabilizer components are very effective in stabilizing n-propyl bromide (NPB). In a standard commercially important 60° C. stability test, representative substituted phenolic compounds used pursuant to this invention, can enable NPB to pass the test even though present at levels of about 50 ppm (wt/wt) or less in NPB containing no other stabilizer additive component. In fact, amounts as low as 1 ppm have been found effective with various substituted phenolic compounds. In addition, it has been found that one of the preferred stabilizers of this invention—2,6-di-tert-butyl-p-cresol—even though higher boiling than NPB, left inconsequential amounts of residue at least throughout the range of 1 to 30 ppm (wt/wt). Also, it has been found that certain other preferred stabilizers of this invention can provide synergistically improved stability in passing the 60° C.

  • Publication number: 20120010119
    Abstract: A blend of hexamethyldisiloxane and dimethyl carbonate displays azeotropic behavior over a surprisingly broad composition range of from about 10% to about 90% by weight dimethyl carbonate. The blends are useful for degreasing, precision cleaning and flux removal from soldered articles, as well as a carrier liquid for particulates such as particulate polytetrafluoroethylene lubricant. Increasing amounts of dimethyl carbonate in the blend provide a more aggressive cleaner. Methods for cleaning, degreasing and flux removal include applying the blends of the invention to articles and drying the articles by drying the applied blends or allowing the applied blends to evaporate. Methods of applying a dispersion of fine particulate material to a surface include utilizing the blends of the invention as a carrier liquid for the particulates and applying the particulate-laden carrier liquid to a surface and removing the carrier liquid by evaporation to leave the dispersed particulates behind.

  • Patent number: 7226726
    Abstract: The developer of the present invention is used in a method where a water-soluble resin coating layer is applied on a resist pattern formed by the conventional method, and the coating layer is crosslinked by an acid supplied from the resist, and the uncrosslinked area in the coating layer is dissolved and removed with a developer to thicken the resist pattern. This developer comprises an aqueous solution containing at least one surfactant selected from an N-acylsarcosinate, an N-acyl-N-methylalaninate, an N-acyltaurinate, an N-acyl-N-methyltaurinate, a fatty acid alkylol amide, and a fatty acid alkylol amide polyoxyethylene adduct.
