| description | It has been researched the influence of nitro group on synthesis of the azo
compound derivatives from vanillin 4-hydroxy-3-methoxy-5-(phenyldiazenil)
benzaldehyde and 4-hydroxy-3-methoxy-5-(p-nitrophenyldiazenil) benzaldehyde as
an indicator of acid-base and anion sensors compounds. Synthesis of 4-hydroxy-3-
methoxy-5-(phenyldiazenil) benzaldehyde was carried out by reacting of
benzenediazonium chloride salt with vanillin in sodium hydroxide solution and gave
40.28% yield. p-Nitrobenzenediazonium chloride salt reacted with vanillin in sodium
hydroxide solution produced 4-hydroxy-3-methoxy-5-(p-nitrophenyldiazenil)
benzaldehyde with 56.64% yield. The test results as halochromic and acidichromic
compounds showed that the 4-hydroxy-3-methoxy-5-(p-nitrophenyldiazenil)
benzaldehyde produced color changes more sharply than 4-hydroxy-3-methoxy-5-
(phenyldiazenil) benzaldehyde. The 4-hydroxy-3-methoxy-5-(phenyldiazenil)
benzaldehyde and 4-hydroxy-3-methoxy-5-(p-nitrophenyldiazenil) benzaldehyde can
be used as an indicator titration of weak acid-strong base. The 4-hydroxy-3-methoxy5-(
phenyldiazenil) benzaldehyde can also be used as a cyanide anion sensor with a
detection limit of 1000 ppm, while 4-hydroxy-3-methoxy-5-(p-nitrophenyldiazenil)
benzaldehyde can detect fluoride and cyanide anions with detection limits of 25 ppm
and 0.5 ppm respectively. |
