Embodiment 1

[0034] Preparation method of 8-aminoquinoline 1,5-naphthalene disulfonic acid zinc metal complex

[0035] The chemical formula of the zinc metal complex of 8-aminoquinoline 1,5-naphthalene disulfonate is Zn(8-aql) 2 (1,5-nd)·2H 2 O, where 8-aql is 8-aminoquinoline and 1,5-nd is 1,5-naphthalene disulfonate.

[0036] Zn(NO 3 ) 2 ·6H 2 O (59.4 mg, 0.2 mmol), NaN 3(26.0mg, 0.4mmol), 1,5-naphthalene disulfonic acid sodium salt (33.2mg, 0.1mmol), 8-aminoquinoline (14.4mg, 0.1mmol) and 5mL of secondary deionized water were added as solvent to In a 25mL autoclave, heat to 130°C, and maintain the temperature for 3 days. After cooling down to room temperature by itself, brown-red flaky crystals were obtained, filtered, and the filter cake was washed with a mixed solvent of water-ethanol (volume ratio: 1:1) to obtain a single crystal of the target complex. The calculated yield based on 8-aminoquinoline was 49.7%. The reaction medium is secondary deionized water, and sodium azide ...

[0038] Preparation method of 8-aminoquinoline 1,5-naphthalene disulfonic acid zinc metal complex

[0039] Zn(NO 3 ) 2 ·6H 2 O (59.4 mg, 0.2 mmol), NaN 3 (26.0mg, 0.4mmol), 1,5-naphthalene disulfonic acid sodium salt (33.2mg, 0.1mmol), 8-aminoquinoline (14.4mg, 0.1mmol) and 5mL of secondary deionized water were added as solvent to In a 25mL autoclave, heat up to 150°C and maintain this temperature for 3 days. After cooling down to room temperature by itself, brown-red flaky crystals were obtained, filtered, and the filter cake was washed with a mixed solvent of water-ethanol (volume ratio: 1:1) to obtain a single crystal of the target complex. The calculated yield based on 8-aminoquinoline was 41.6%.

Embodiment 3

[0041] Preparation method of 8-aminoquinoline 1,5-naphthalene disulfonic acid zinc metal complex

[0042] Zn(NO 3 ) 2 ·6H 2 O (59.4 mg, 0.2 mmol), NaN 3 (52.0mg, 0.8mmol), 1,5-naphthalene disulfonic acid sodium salt (33.2mg, 0.1mmol), 8-aminoquinoline (14.4mg, 0.1mmol) and 5mL of secondary deionized water were added as solvent to In a 25mL autoclave, heat up to 150°C and maintain this temperature for 3 days. After cooling down to room temperature by itself, brown-red flaky crystals were obtained, filtered, and the filter cake was washed with a mixed solvent of water-ethanol (volume ratio: 1:1) to obtain a single crystal of the target complex. The calculated yield based on 8-aminoquinoline was 37.5%.

Abstract

The invention discloses a sulfonic acid zinc metal organic complex, which relates to the technical field of organic synthesis, the complex is 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex, the chemical formula of the 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex is Zn (8-aql)2(1,5-nd).2H2O, the invention also provides a preparation method of the complex, which comprises the following steps: reacting zinc nitrate hexahydrate, sodium azide, 1, 5-naphthalene disulfonic acid sodium salt and 8-aminoquinoline in secondary deionized water at 120-180 DEG Cfor 3 days, cooling to room temperature, filtering, and washing to obtain the complex. The invention also provides the application of the complex in detection of carbon disulfide and nitrobenzene. The 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex has the beneficial effects that the 8-aminoquinoline 1, 5-naphthalene disulfonic acid zinc metal complex prepared by the method can be used for detecting low-concentration carbon disulfide in the environment and can also be used for detecting low-concentration nitrobenzene in the environment.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, in particular to a sulfonic acid zinc metal organic complex and its application. Background technique [0002] Carbon disulfide and nitrobenzene are important chemical raw materials and are widely used in fine chemicals, polymers, metallurgy, pesticides and other industries. Among them, carbon disulfide is a poison that damages nerves and blood vessels. Long-term exposure to low concentrations will cause extreme harm to the human body, causing damage to blood vessels, nerves, and major organs of the body; long-term exposure to low concentrations of nitrobenzene can cause blood system, nervous system, etc. Systemic lesions such as the digestive system are one of the first batch of blacklisted substances for priority control of pollutants in water in my country. [0003] At present, the methods for detecting these two compounds mainly include spectrophotometry, chromatography, and electro...
