Patent number: 8129325Abstract: 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.Type: GrantFiled: November 5, 2004Date of Patent: March 6, 2012Assignee: Albermarle CorporationInventors: Bonnie Gary McKinnie, Joseph H.

Patent number: 5767048Abstract: A cleaning process which comprises contacting a printed circuit board to which a residue of a flux is attached with a cleaning composition containing a first solvent and an organic compound, and then with a second solvent. The first solvent is an aliphatic hydrocarbon solvent having 5 to 20 carbon atoms. The organic compound is a 1-alkyl-2-pyrrolidone having 3 to 18 carbon atoms, a tri-alkylphosphine oxide having 3 to 8 carbon atoms or a di-alkylsulfoxide having 3 to 8 carbon atoms. The organic compound is in an amount of 10 to 300 g per liter of the hydrocarbon solvent. The cleaning composition does not contain a halogen compound.Type: GrantFiled: May 28, 1997Date of Patent: June 16, 1998Assignee: Kurita Water Industries Ltd.Inventor: Hiroshi Obuse
