異項環アンモニウム鹽合成に關する基礎研究 (環状アンモニウム鹽色素の製法 XII)

Synthesis of aromatic heterocyclic ammonium salt was studied as a material for the syntheses of cyclic ammoninm salt dyes. Several knowledges were obtained as to the difference in the formation rate of salts according to the kinds of alkyl and halogen used for alkyl halides and according to the kind of aromatic heterocyclic bases. The experiments were carried out by reacting the equivalent moles of the base and alkyl halide in MeOH under a definite condition and the amount of salt formed was determined by measuring the specific resistance of the reacting solution. As the number of carbon atoms in the alkyl radical increases, the reaction rate decreases. The reaction rate is increased in the order of Cl<Br<I.
