Properties and stability
Nearly colorless crystals. It is slightly alkaline. There is a spicy smell and a burning taste. Dilute solutions of acridine and its salts have green or purple fluorescence respectively. Coal tar contains acridine, mainly concentrated in an anthracene oil fraction.
Storage method
This product should be sealed and stored away from light.
Synthesis method
Prepared from acridone. Acridone is composed of diphenylamine-2- Carboxylic acid is obtained by ringing with sulfuric acid, and then reduced with pentanol and sodium to form9,10-Dioxoacridine is oxidized to obtain acridine. For laboratory preparation, acridone can also be mixed with zinc powder and heated. The acridine sublimation product generated by the reaction is dissolved in hydrochloric acid, and then alkalized with sodium hydroxide solution to precipitate and filter to obtain a crude product. Recrystallizing with methanol gives a melting point of 110 ℃‘s finest products.
Purpose
Reagents for the determination of cadmium, germanium, cobalt, bismuth and zinc.
The structure of acridine is similar to that of anthracene, and its chemical properties are also very close. After the hydrogen on the benzene ring of acridine is replaced by an amino group, it is an intermediate of acridine dye. Among acridine compounds, some have antiseptic properties and can be used as medicines, such as acriflavine and adipine.
