    Abstract: NEW MATERIAL:1,10-Bis(4-nitrophenyl)-1,3,5,7,9-decapentaene shown by formula I. USE:An intermediate for a bisazo compound useful as an organic photoconductive material suitable for not only high-speed copying machines but also electrophotographic sensitized substance showing practically high sensitivity for laser printer, especially a lamination type sensitized substance. PREPARATION:A bisphosphonium salt shown by formula II (R is phenyl or alkyl; X is halogeno ion) is reacted with trans-4-nitrocinnamic aldehyde in the presence of a basic catalyst at room temperature - about 100 deg.C to give a compound shown by formula I. The nitro group of the compound is reduced with an amino group and then diazotized to give a bis(diazonium) salt, which is coupled with a coupler to give a bisazo compound shown by formula III (Ar is coupler residue).

    Abstract: PURPOSE: When chlorobenzene is nitrated with nitric acid in the presence of sulfuric acid, the reaction temperature is set in a specific range to facilitate the temperature control and produce an isomer mixture of nitrochlorobenzene with no side-reactions, which is used as an intermediate of dyes.
    CONSTITUTION: Chlorobenzene is nitrated with nitric acid in the presence of sulfuric acid, preferably of 70W90% concentration, at 85W150°C to produce an isomer mixture of nitrochlorobenzene. The nitration is effected preferably by dropping a mixed acid of sulfuric and nitric acids to a suspension of chlorobenzene in sulfuric acid. The weight ratio of sulfuric acid to chlorobenzene is preferably 1.5W3.0.

    Abstract: PURPOSE:To obtain the titled compound in high selectivity and in high yield, by reacting an inexpensive lower alkyl chloride as a raw material which exists in an organic phase with an alkali metal salt of nitric acid in a solid phase using a catalyst transferring between phases under mild conditions. CONSTITUTION:A 1-3C lower alkyl chloride is present directly in the absence of a solvent, or is dissolved in a hydrophobic organic solvent so that it exists in the organic phase, while an alkali metal salt of nitric acid is made to exist in solid state directly in a solid phase. The both compounds are reacted using a catalyst transferring between the organic and solid phases, to give a corresponding lower nitroparaffin. A large cyclic polyether, e,g., dibenz-18-crown-6, etc. or a crypstand shown by the formula (l, m, and n are 0-2) may be used as the catalyst transferring between the phases. The reaction temperature is preferably 5-90 deg.C, the pressure is normal pressure to 5kg/cm G, and, if necessary, it may be reduced pressure.
