Abstract

The invention provides 8-hydroxyquinoline functionalizedpillar[5]arene. The 8-hydroxyquinoline functionalizedpillar[5]arene (PQ8) is a white solid obtained by taking acetonitrile as a solvent, bilateral 1,4-dibromobutane modified pillararene and 8-hydroxyquinoline as reaction substrates, performing reacting at 80-85 DEG C for 70-72 hours under the action of K2CO3 and KI and the protection of N2 and carrying out separating by column chromatography after the reaction is finished. The PQ8 solid powder is exposed in steam of acetonitrile, dichloromethane, chloroform, formaldehyde, pyridine, tetrahydrofuran, ammonia water, n-propylamine, n-butylamine, 1,6-hexamethylenediamine, 1,10-decamethylene diamine and ethidene diamine, and only the steam of ethidene diamine enables the fluorescence color of the solid powder of the 8-hydroxyquinoline functionalized pillar[5]arene to change from blue to faint yellow, so single selective detection of ethylenediamine can be realized; and meanwhile, the PQ8 can realize the adsorption of the ethanediamine, and the molar adsorption rate of the ethanediamine can reach 176.19%.

Description

technical field

[0001] The present invention relates to a kind of 8-hydroxyquinoline functionalized column [5] arene and its synthesis method; the present invention also relates to the application of 8-hydroxyquinoline functionalized column [5] arene in detection and adsorption of ethylenediamine, The invention belongs to the fields of chemical synthesis, VOCs detection and adsorption. Background technique

[0002] Ethylenediamine (EDA, C 2 h 6 N 2 ) is a common volatile organic compound, which is mainly used in polymer resin, printing and dyeing industry, electroplating industry, pesticide industry and pharmaceutical production. The vapor of this compound is highly irritating to human mucous membranes and skin, and can cause conjunctivitis, bronchitis, pneumonia, pulmonary edema, and contact dermatitis. Direct contact of the skin and eyes with its liquid can cause burns, and severe liver and kidney damage; Moreover, this compound can also cause occupational asthma and c...
