Symbols of Risks shoulder: yellow toxic environmental impact corrosive gas, liquified For additional safety information see Material-/safety data sheet No. *-NH3-002 Description Colourless, toxic, corrosive, strong hygroscopic, liquified gas with characteristic odor. May cause chemical burns to skin and cornea. Ammonia forms explosive atmospheres with oxidizing gases, with halogens and Mercury. Very high solubility in water (alkaline). Strong exotherm reaction with acids. In presence of humidity strong corrosive behaviour against aluminium, copper, silver and zinc. detection Fog-forming with vapours of HCl, testing tubes Safety data Explosion Range Ignition Temperature TLV 15,4 - 31,6 Vol.% 630 °C 50 ml/m3 Materials Cylinders and Valves: any usual materials; except brass and copper(alloys) At brass resp. copper danger of stress corrosion cracking caused by humidity Seals: PTFE, PCTFE, PA, PE, PP, Physical Properties molecular weight Critical Point temperature Pressure density Triple Point temperature Pressure Boiling Point temperature liquid density evaporation heat Version: 2.0 17,304 kg/kmol 405,50 K 113,53 bar 0,234 kg/l 195,25 K 0,0607 bar 239,82 K; -33,3 °C 0,6819 kg/l 1368,11 kJ/kg vapour pressure at 20°C gas density at 0°C and 1,013 bar density ratio to air gas density at 15°C and 1 bar Conversion Factor liquid at Ts to m3 gas (15°C, 1 bar) Virial Coefficient Bn at 0°C B30 at 30°C Gaseous State at 25°C and 1 bar specific heat capacity cp thermal conductivity dynam. viscosity 8,5737 bar 0,7714 kg/m3 0,5966 0,71979 kg/m3 0,947 -14,9*10-3bar-1 -9,7*10-3 bar-1 2,0757 kJ/kg K 242 *10-4 W/m K 10,02*10-6 Ns/m2 Messer Group GmbH Gahlingspfad 31 47803 Krefeld [email protected] www.messergroup.com
