Title: Production of quinolinic acid
Inventor: FURUKAWA YOSHIRO
IPC: C07D213/807
Filed: 1989-11-13
Abstract: PURPOSE:To obtain a compound useful as an intermediate for pressuresensitive dyestuff, drugs, agricultural chemicals, etc., from inexpensive, readily obtainable raw materials by oxidizing quinoline with chlorite ion in the presence of a ruthenium compound. CONSTITUTION:Quinoline is oxidized with chlorite ion in an acidic water medium (e.g. sulfuric acid) in the presence of a ruthenium compound (e.g. ruthenium trichloride) at 40-80 deg.C to give the objective quinolinic acid, namely 2,3- pyridinedicarboxylic acid. 3-8mol chlorite ion is used based on 1mol quinoline, the amount of the acid used as a solvent is 0.4-10 acid equivalent and 10<-5> to 10<-2>mol ruthenium compound is used. 10-50% aqueous solution of sodium chlorite is preferable as the chlorite ion. Since the oxidizing agent is the chlorite having three or more times as much effective chlorine amount as a hypochlorite, reaction volume per yield is reduced.

Filed: 1996-11-08
Abstract: PROBLEM TO BE SOLVED: To fasten segments when changing bolt size by producing a socket of nut runner of a fastening machine in alignment with a maximum bolt for building a tunnel and having a size varying hardware suited to smaller bolts. SOLUTION: For instance, a maximum bolt 1a is used for building a tunnel, and a nut 2a is tightly adhered and fitted to a socket 3 of nut runner. In this case, at the deep point of the socket 3, a ring-shaped magnet 5 is attached to attract the nut 2a.
