CAS号 EC号 Hill配方 摩尔质量 109-99-9 203-726-8 C₄H₈O 72.11 g/mol 描述 产品目录编号 108110 同义词 THF, Tetramethylene oxide, Oxolane, Butylene oxide 概述 Accurate analytic results in UV/VIS and infrared spectroscopy depend on the use of very pure solvents for sample preparation. The Uvasol® solvents range has been specially designed for spectroscopy and other applications requiring solvents of the highest spectral purity. The refinement process allows a greater degree of security in applications and avoids misinterpretation of analytical results caused by traces of UV, IR and fluorescence contamination. Uvasol® solvents offer best UV transmittance. In all specifications the minimum transmittance for 5 typical wavelengths are identified. Furthermore the transmittance is specified in accordance with Reag. Ph Eur and ACS. 产品信息 CAS号 109-99-9 EC索引编号 603-025-00-0 EC号 203-726-8 Hill配方 C₄H₈O Molar Mass 72.11 g/mol HS代码 2932 11 00 结构配方图像 理化信息 沸点 65 - 66 °C (1013 hPa) 密度 0.89 g/cm³ (20 °C) 汽化值 2.3 爆炸极限 1.5 - 12.4 %(V) 闪点 -20 °C 燃点 215 °C 熔点 -108.5 °C pH值 7 - 8 (200 g/l, H₂O, 20 °C) 蒸汽压力 173 hPa (20 °C) 溶解度 (20 °C) 可溶 GHS安全信息 危害性图示
