| Abstract: | With N-methyl pyrrolidone as solvent,Phosphorus trichloride as earlier stage catalyst,triphenyl phosphite which has pretreated as a later period catalyst together 1,2-ethylenediamine as coordination catalyst and under the congdition of vacuum degree was 0.06~0.098MPa while highest temperature was beyond 110 degree,Naphthol AS-BI could be obtained by 5-Aminobenzimidazolone reacting with 2-hydroxy-3-naphthoic acid through N-acylation condensation reaction.The final product which purity was up to 99.5 percent(HPLC)was earned by the course of adding sodium carbonate to to neutralize,three water washing under certain pressure.New technology has been in motion in industrial equipment for over one year. |
| Keywords: | Naphthol AS - BI 5 - Aminobenzimidazolone N - acylation reaction organic pigmentintermediate |
