2-丁炔二醇(2-butynedio1)又称1,4-二羟基-2-丁炔(1,4-dihydroxy-2-butyne),分子式为C4H6O2,分子量为86.1
白色斜方结晶;熔点58℃,沸点238℃、145℃(15×133.3Pa),闪点152℃,折射率(n9)1.450;溶于水、醇和丙酮,微溶于氯仿,不溶于苯和醚;化学性质活泼;能刺激皮肤,有毒。
以多聚甲醛为原料,以乙炔铜为催化剂,以环己酮为溶剂,将乙炔通入反应器中,控制温度为115~120℃,直至甲醛全部转化后,停止通乙炔,反应液经过滤除去催化剂,再经浓缩、结晶即得丁炔二醇。

2-butynediol (2-butynedio1) is also called 1,4-dihydroxy-2-butyne (1,4-dihydroxy-2-butyne). The Molecular formula is C4H6O2, and the molecular weight is 86.1
White rhombic crystal; Melting point 58 ℃, boiling point 238 ℃, 145 ℃ (15 × 133.3Pa), flash point 152 ℃, refractive index (n9) 1.450; Soluble in water, alcohol, and acetone, slightly soluble in chloroform, insoluble in benzene and ether; Active chemical properties; It can irritate the skin and is toxic.
With Paraformaldehyde as the raw material, Copper(I) acetylide as the catalyst, Cyclohexanone as the solvent, acetylene is passed into the reactor, and the temperature is controlled at 115~120 ℃. After all formaldehyde is converted, acetylene is stopped. The reaction solution is filtered to remove the catalyst, and then concentrated and crystallized to obtain butynediol.
The development of HH-BYD packed column by Haohan Chromatography for the determination of 2-butynediol content has yielded satisfactory results.
