Abstract: Volume II/19 Molecular Constants mostly from Microwave, Molecular Beam and Sub-Doppler Laser Spectroscopy is a supplement to the earlier volumes II/4, II/6, and II/14. The slight change in the title reflects current trends in the applications of spectroscopic methods. Together, the four volumes collect all the critically evaluated data published up to 1989/90 on constants of free molecules obtained by classical and modern spectroscopy. Volume II/19 is divided into four parts to record the growing number of in

其他信息

  • 外观性质:无色无臭气体。
  • vapor pressure:635 psi ( 21 °C)
  • 用途一:用作低温(-100℃)制冷剂,电子工业等离子体化学蚀刻剂及氟有化合物的原料
  • MOL 文件:75-46-7.mol
  • TSCA:T
  • MSDS 信息:三氟甲烷(75-46-7).msds
  • 质量标准:三氟甲烷,又称HFC-23,是一种高压液化汽,可用作制冷剂,替代CFC-13(R13)。同时又是哈龙1301的理想替代品,具有清洁、低毒、灭火剂效果好等特点。 图2为三氟甲烷灭火剂和致冷剂参考技术指标
  • 蒸气密度:2.43 (vs air)
  • 理化性质:三氟甲烷是一种无色,几乎无味,不导电的气体。是一氯二氟甲烷R-22(CHClF2)生产过程中产生的一种不可避免的副产物,是一种强温室气体,其温室效应潜值(GWP=5.7)是CO2的14800倍,在大气层的寿命高达264年,且是目前已知的温室效应第二高的温室气体。三氟甲烷主要用作低温(-100℃)制冷剂,电子工业等离子体化学蚀刻剂及氟有化合物的原料。也可作为有机合成中间体,可与多种物质反应制备三氟甲基化合物,二氟甲基化合物,含氟烷烃,含氟烯烃等。 毒性: 在狗体上进行试验,测定心脏对三氟甲烷的敏感度,狗分别暴露于30%,50%的三氟甲烷药剂(其余为空气)下5min,均无严重的心率不齐发生。其他试验表明,当三氟甲烷浓度达到80%时,动物体内未发现心率不齐现象。当三氟甲烷暴露于明焰下,会分解并产生氢氟酸(HF)。 溶解性: 在恒定温度下,三氟甲烷的溶解度随其分压的升高线性增加。在273.15 K和不同气相压力下,各种溶剂对三氟甲烷的溶解度顺序为:丙酮>无水乙醚>甲醇≈碳酸二乙酯≈磷酸三甲酯>正丁醇>正己烷>氯仿>二苯醚>浓硫酸≈甘油≈氯化石蜡-52。 图1为三氟甲烷分子结构式。
