CAS号 EC号 Hill配方 化学配方 摩尔质量 1634-04-4 216-653-1 C₅H₁₂O (CH₃)₃COCH₃ 88.15 g/mol 描述 产品目录编号 101984 同义词 MTBE, MTB, 2-Methoxy-2-methylpropane, Methyl tert-butyl ether 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 1634-04-4 EC索引编号 603-181-00-X EC号 216-653-1 Hill配方 C₅H₁₂O 化学配方 (CH₃)₃COCH₃ Molar Mass 88.15 g/mol HS代码 2909 19 90 结构配方图像 理化信息 沸点 55.3 °C (1013 hPa) 密度 0.74 g/cm³ (20 °C) 爆炸极限 1.5 - 8.5 %(V) 闪点 -28 °C 燃点 460 °C 熔点 -108.6 °C pH值 (H₂O) 不适用 蒸汽压力 268 hPa (20 °C) 溶解度 42 g/l (20 °C) 毒性学信息 LD 50口服 LD50 Rat > 2000 mg/kg LD 50皮下注射 LD50 Rabbit > 2000 mg/kg GHS安全信息 危害性图示
