1,1,1,2-Tetrafluoroethane as a pharmaceutical excipient for polymer porous microsphere filled column
Details of 1,1,1,2-tetrafluoroethane as a pharmaceutical excipient for the application of polymer porous microsphere filled column:
Pharmaceutical excipient tetrafluoroethane (HFC-134a)
1、 Basic information
Product name: medicinal excipient 1,1,1,2-tetrafluoroethane
Molecular formula: CH2FCF3
Relative molecular weight: 102.03
Product standard: G/JHGF O1 J 20 209-2012
2、 Physical and chemical properties: it is a colorless gas with slight ether odor under normal temperature and pressure; Melting point - 103.15 ℃, boiling point - 26.1 ℃, liquid density 1.206g/cm3 (25 ℃); Generally, they are compressed into liquid and stored in steel cylinders, and their thermal properties are similar to R12. Ozone depletion potential (ODP) is 0, and global warming potential (GWP) is 1200.
3、 Product use:
1,1,1,2-tetrafluoroethane is the main substitute for CFCs sprays. At the same time, due to its low toxicity and non-flammability, it has been developed as a carrier for drug inhalers (i.e. medical aerosols). Anti-asthmatic aerosol used to treat asthma, COPD (chro

HG/T 6052-2022混合制冷剂 R507 系列不凝气测定 详细信息：
制冷剂中的不凝性气体(ＮＣＧ)主要是由液相制冷剂中原始空气积累起来的。制冷剂中含有过高的ＮＣＧ会使制冷机械的参数发生变化,从而影响制冷效果。在和外商的业务往来中获悉,外商对制冷剂中ＮＣＧ含量十分重视。本文件规定了混合制冷剂 R507 系列的要求、试验方法、检验规则、标志、包装、运输、贮存和安全。
本文件适用于以 1,1,1-三氟乙烷、五氟乙烷为原料，按一定的质量配比经混合而制得的混合制冷剂 R507 系列
