Al-Majidi AU - Mohammed G.A Al-Khuzaie* PY - 2019 VL - 60 IS - 11 SP - 2341 EP - 2352 JO - Iraqi Journal of Science المجلة العراقية للعلوم SN - 00672904 23121637 AB - New Azo compounds containing an 1,8-naphthalimide moiety were synthesizedfrom 1, 8-naphthalic anhydride by a reaction with p-phenylenediamine or benzidineto produce 1,8-naphthalimide derivatives (1 or 2), which were converted todiazonium salt derivatives by using sodium nitrite and acetic acid at 0-5 ᵒC. Thediazonium salt was subjected to a coupling reaction with different substituted phenolin alkaline media at 0-5 ᵒc to produce azo compound derivatives (3-14).The New Azo compound derivatives (3-14) were identified by 1H-NMR, 13C-NMR,and FTIR and by measuring characteristic physical properties and specific reactions.Also, the ability of the prepared azo compounds to work as acid-base indicator wasinvestigated, since azo dyes have different and sharp colors in acidic or basicsolutions.
