Granted: 1997-02-06
Abstract: 2-(4,6-dimethoxypyridine-2-yl) oxyacetophenone derivative of general formula(I) is prepared by the following method.  (1) A compound of general formula(II) reacts with alcohol, thiol or carboxyl acid in the presence basic and solvent. Or the compound(II) reacts to alcohol, thiole or carboxylic metal salts under solvent to produce a compound of general formula(III). (2) Then a compound(III) reacts to 2,6-dimethoxy-4-methylsulfonyl pyrimidine in the presence basic and solvent at 15~120degree C. In the formula, R is halogen, alkyl with carbon number 1~4, alkoxy group with carbon number 1~4, aryloxy or (4,6-dimethoxy pyrimidine-2-yl)oxy as substituents substituted at number 5 or 6 of benzene ring. X is halogen atom, hydroxy, alkylthio with carbon number 1~4, thiole, arylthio or nitro group.

Title: Air bag fabrics characterised by super blocking
Inventor: MUN SONG-YOP
IPC: D03D1/02
Filed: 1993-12-18
Granted: 1995-09-30
Abstract: The fabric for an air bag is produced by coating a polychloroprene rubber resin on the polyamide (esp. nylon 66) filament yarn, and heat treating the coated fabric by the use of an embossing roll having cross-shaped embossed patterns at 100-120 deg.C. In the embossed patterns, the each angle is 90 degree, the length is 0.05-50mm, and the height is 0.05-50mm. The fabric has good blocking property, tear strength and durability.

Title: Niobium analysis method in stainless steel
Inventor: LEE WANG-BYUNG
IPC: G01N23/00
Filed: 1993-12-30
Granted: 1997-03-05
Abstract: A process for analyzing niobium included in stainless steel is disclosed. In the process, a stainless steel sample is decomposed by an acidoid. The sample solution is resolved. A niobium residue is separated and extracted form the stainless steel sample by adding  tannin acid hereto. The stainless steel sample is put and dried in a platinum dish. Then a mixing solvent(Na2CO3:H3PO3=3:1) covers the niobium residue and the stainless steel sample is slowly melted at 1800 deg C to thereby remove the tannin acid included in the niobium residue. The melted stainless steel sample is again melted in a resistance furnace at more than 1000 deg C. The melt material is melted by 20% tin acid solution to obtain a sample. The sample is analyzed by an induced combination plasma atom emission spectroscopic analysis method.
