    摘要: Oligoanilines of the general formula (1) exhibiting absorption coefficient (ε) of 30 or below at 560 nm are obtained by dissolving a crude oligoaniline which contains an oligoaniline of the general formula (1) and oxides thereof and exhibits an absorption coefficient (ε) of 80 to 1000 at 560 nm in a solvent to form an oligoaniline solution, treating the solution with 4 to 20% by mass of activated carbon based on the crude oligoaniline, and subjecting the resulting solution to recrystallization. According to the process, oligoanilines which little contain impurities and can exert electroluminescent characteristics with high reproducibility can be obtained. [wherein R1 to R3 are each independently hydrogen, hydroxyl, or the like; A and B are each independently a divalent group represented by the general formula (2) or (3), R4 to R11 are each independently hydrogen, hydroxyl, or the like; and m and n are each independently an integer of 1 or above and satisfy the relationship: m+n≦20.]

    摘要: Sertraline hydrochloride, (1Scis)-4-(3,4-dichlorophenyl)-1,2,3,4-tetrahydro-N-methyl-1-naphtalenaminehydrochloride, polymorph II is prepared by extracting or dissolving the sertraline base into ethyl acetate, adding isopropanol as a solvent, adding hydrogen chloride dissolved in ethyl acetate or in gaseous form, and finally isolating and drying sertraline hydrochloride polymorphic form II.
