2,2'-Bipyridine

A,A'-디피리딜 C화학적 특성, 용도, 생산

물성

백색 기둥 모양 결정(석유 에테르 또는 에탄올-물에서 재결정). 녹는점 69.5℃, 끓는점 272.5℃. 에탄올, 에테르, 벤젠, 리그로인에 쉽게 녹는다. 물에 잘 안 녹는다. 산성 용액 속에서 철(Ⅱ)이온과 착물 [FeⅡ(C10H8N2)3]X2를 만들어 강한 적색을 띠지만, 철(Ⅲ) 이온과는 적색을 나타내지 않는다.

용도

철(Ⅱ)의 비색 정량 시약으로서 이용된다. 철(Ⅱ)와 pH 3~9에서 완전히 발색하고, 흡수 극대 파장 522mμ, 발색은 매우 안정적이다. 정량 범위 0.1~4ppm. [FeⅡ(C10H8N2)3]X2는 산화하면 청록색의 [FeⅢ(C10H8N2)3]X3가 된다. 이 반응은 가역성이기 때문에 산화 환원 지시약으로 쓰여진다.

화학적 성질

White to light red crystalline powder. Soluble in ethanol, ether, benzene, chloroform and petroleum ether, 1 part of this product is about 200 parts of water.

용도

2,2'-bipyridine acts as a bidentate chelating ligand which form complexes with transition metal ions and shows antifungal, antibacterial and antiviral activity. It is used for the colorimetric determination of iron as well as oxidation reduction indicators to confirm the presence of ferrous ion in soils. It forms complexes with ruthenium and platinum, exhibit intense luminescence, which may have practical applications. Copper(I) bipyridine complexes involved in the oxidation of alcohols under aerobic conditions.

제조 방법

2,2'-bipyridine is synthesized by the reaction of pyridine with ferric chloride. Take 70g of anhydrous pyridine and mix with 13g of anhydrous ferric chloride, heat and react at 300℃ in a sealed tube for about 35h. After cooling, the reactant solidified into red-black crystals, the sealing tube was opened, and the red-black solution of the solid was washed out with a small amount of hot water. The oily impurities were removed by extraction with ether. After neutralization with sodium bicarbonate, excess pyridine was removed by heating with steam. The mixture was then made strongly basic, and the 2,2'-bipyridine was distilled off with steam.

정의

ChEBI: 2,2'-bipyridine is a bipyridine in which the two pyridine moieties are linked by a bond between positions C-2 and C-2'. It has a role as a ferroptosis inhibitor and a chelator.

일반 설명

2,2′-Bipyridyl, is a symmetrical bipyridine commonly used as a neutral ligand for complexation with metal ions. The molecule is planar with trans-conformation and crystallizes in the monoclinic crystal system.

Safety Profile

Poison by ingestion,subcutaneous, and intraperitoneal routes. Experimentalteratogenic data. Questionable carcinogen withexperimental tumorigenic data. Mutation data reported.When heated to decomposition it emits toxic fumes ofNOx.

Purification Methods

2,2'-Bipyridyl crystallises from hexane, or EtOH, or (after charcoal treatment of a CHCl3 solution) from pet ether. Also, it precipitates from a concentrated solution in EtOH by addition of H2O. Dry it in a vacuum over P2O5. It can be further purified by chromatography on Al2O3 or by sublimation. UV (EtOH): at 280nm (log 4.13). max [Airoldi et al.
