International Chemical Safety Cards PYRROLIDONE ICSC: 0562 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: LIGHT YELLOW LIQUID. PHYSICAL DANGERS: CHEMICAL DANGERS: The substance decomposes on heating or on burning producing toxic fumes including nitrogen oxides. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV not established. ROUTES OF EXPOSURE: The substance can be absorbed into the body through the skin. INHALATION RISK: A harmful contamination of the air will not or will only very slowly be reached on evaporation of this substance at 20°C; on spraying or dispersing, however, much faster. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the skin, the eyes and the respiratory tract. PHYSICAL PROPERTIES Boiling point: 245°C Melting point: 25°C Relative density (water = 1): 1.1 Solubility in water: good Vapour pressure, Pa at 20°C: negligible Relative vapour density (air = 1): 2.9 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.00 Flash point: 129°C o.c.
