International Chemical Safety Cards 1-DODECENE ICSC: 1567 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: CHEMICAL DANGERS: Reacts with strong oxidants , halogens and inorganic acids . Attacks rubber, paints and lining materials. OCCUPATIONAL EXPOSURE LIMITS: TLV not established. MAK not established. ROUTES OF EXPOSURE: 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: If this liquid is swallowed, aspiration into the lungs may result in chemical pneumonitis. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: The liquid defats the skin. PHYSICAL PROPERTIES Boiling point: 214°C Melting point: -35°C Relative density (water = 1): 0.8 Solubility in water: none Vapour pressure, Pa at 25°C: 2 Relative vapour density (air = 1): 5.81 Flash point: 77 °C c.c. Auto-ignition temperature: 225°C Octanol/water partition coefficient as log Pow: 6.1 ENVIRONMENTAL DATA Bioaccumulation of this chemical may occur in aquatic organisms.
