International Chemical Safety Cards DIISOPROPYLAMINE ICSC: 0449 DIISOPROPYLAMINE DIPA N-(1-methylethyl)-2-propanamine C6H15N / CH3-CH(CH3)-NH-CH(CH3)-CH3 Molecular mass: 101.2 CAS # 108-18-9 RTECS # IM4025000 ICSC # 0449 UN # 1158 EC # 612-048-00-5 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Highly flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. NO contact with oxidants. Powder, alcohol-resistant foam, water spray, carbon dioxide. EXPLOSION Vapour/air mixtures are explosive. Closed system, ventilation, explosion-proof electrical equipment and lighting. Prevent build-up of electrostatic charges (e.g., by grounding). In case of fire: keep drums, etc., cool by spraying with water. EXPOSURE PREVENT GENERATION OF MISTS! STRICT HYGIENE! INHALATION Burning sensation. Cough. Headache. Nausea. Shortness of breath. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration if indicated. Refer for medical attention. SKIN MAY BE ABSORBED! Pain. Blisters. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention. EYES Redness. Pain. Blurred vision. Severe deep burns. Safety spectacles, or eye protection in combination with breathing protection. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION Abdominal cramps. Burning sensation. Nausea. Shock or collapse. Sore throat. Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Refer for medical attention. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Collect leaking and spilled liquid in sealable containers as far as possible. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer. Wash away remainder with plenty of water (extra personal protection: complete protective clothing including self-contained breathing apparatus). Separated from strong oxidants, strong acids. Cool. Well closed. Keep in a well-ventilated room.

International Chemical Safety Cards DIISOPROPYLAMINE ICSC: 0449 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID , WITH CHARACTERISTIC ODOUR. PHYSICAL DANGERS: The vapour is heavier than air and may travel along the ground; distant ignition possible. CHEMICAL DANGERS: The substance decomposes on heating, producing toxic fumes of nitrogen oxides. The substance is a strong base, it reacts violently with acid and is corrosive to copper and zinc and their alloys, aluminium and galvanized steel. Reacts violently with oxidants causing fire and explosion hazard. Attacks some forms of plastics. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV: 5 ppm; 21 mg/m3 (skin) (ACGIH 1996). OSHA PEL: TWA 5 ppm (20 mg/m3) skin NIOSH REL: TWA 5 ppm (20 mg/m3) skin NIOSH IDLH: 200 ppm ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation of its vapour, through the skin and by ingestion. INHALATION RISK: A harmful contamination of the air can be reached very quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: Tear drawing. The vapour is corrosive to the eyes and the respiratory tract. Inhalation of the vapour may cause lung oedema (see Notes). Contact of the eyes with the vapour or liquid may induce visual disturbances. Exposure may result in death. The effects may be delayed. Medical observation is indicated. EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact with skin may cause dermatitis. PHYSICAL PROPERTIES Boiling point: 84°C Melting point: -61 (see Notes)°C Relative density (water = 1): 0.72 Solubility in water: none Vapour pressure, kPa at 20°C: 9.3 Relative vapour density (air = 1): 3.5 Flash point: -6°C o.c. Auto-ignition temperature: 316°C Explosive limits, vol% in air: 0.8-7.1 Octanol/water partition coefficient as log Pow: 1.64 ENVIRONMENTAL DATA The substance is harmful to aquatic organisms. N O T E S Other reported melting points: -91°C and -96°C. The symptoms of lung oedema often do not become manifest until a few hours have passed and they are aggravated by physical effort. Rest and medical observation are therefore essential. Immediate administration of an appropriate spray, by a doctor or a person authorized by him/her, should be considered.
