3-피리딘올 C화학적 특성, 용도, 생산
화학적 성질
white to light yellow crystal. Soluble in alcohol and water, slightly soluble in ether and benzene. It becomes a red solution when it encounters ferric chloride, and it is easy to decompose in the air.용도
3-Hydroxypyridine (cas# 109-00-2) is a compound useful in organic synthesis.정의
ChEBI: 3-Hydroxypyridine is a monohydroxypyridine that is pyridine in which the hydrogen at position 3 has been replaced by a hydroxy group. It has been detected as a thermal degradation product from the smoke of the burning leaves of Salvia divinorum, a Mexican psychoactive plant.제조 방법
3-hydroxypyridine was prepared by reacting furfurylamine with H2O2 in the presence of HCl, followed by hydrolysis. The optimal conditions were found as fellows: molar ratio of furfurylamine: HCl : H2O2 = 1 : 5 : 1.1, and H2O2 added dropwisely at 0-5 °C, and then refluxed at 100-105 °C for 0.5 h.Purification Methods
Crystallise 3-hydroxypyridine from *C6H6, water or EtOH. [Beilstein 21 III/IV 402, 21/2 V 68.]3-피리딘올 준비 용품 및 원자재
