International Chemical Safety Cards BUTYL ACRYLATE ICSC: 0400 BUTYL ACRYLATE Acrylic acid n-butyl ester 2-Propenoic acid, butyl ester CH2=CHCOOC4H9/C7-H12-O2 Molecular mass: 128.2 CAS # 141-32-2 RTECS # UD3150000 ICSC # 0400 UN # 2348 EC # 607-062-00-3 TYPES OF HAZARD/ EXPOSURE ACUTE HAZARDS/ SYMPTOMS PREVENTION FIRST AID/ FIRE FIGHTING FIRE Flammable. NO open flames, NO sparks, and NO smoking. See Chemical dangers. Powder, AFFF, foam, carbon dioxide. EXPLOSION Above 37°C explosive vapour/air mixtures may be formed. Closed system, ventilation, explosion-proof electrical equipment and lighting. Above 37°C use a closed system, ventilation, and explosion-proof electrical equipment. In case of fire: keep drums, etc., cool by spraying with water.   EXPOSURE PREVENT GENERATION OF MISTS! STRICT HYGIENE! INHALATION Burning sensation. Cough. Shortness of breath. Sore throat. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Refer for medical attention. See Notes. SKIN Redness. Pain. Protective clothing. Remove contaminated clothes. Rinse and then wash skin with water and soap. EYES Redness. Pain. Face shield. First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then take to a doctor. INGESTION (further see Inhalation). Do not eat, drink, or smoke during work. Rinse mouth. Do NOT induce vomiting. Rest. SPILLAGE DISPOSAL STORAGE PACKAGING & LABELLING Eliminate all ignition sources. Collect leaking liquid in covered containers. Absorb remaining liquid in sand or inert absorbent and remove to safe place. Do NOT wash away into sewer (extra personal protection: A filter respirator for organic vapours). Fireproof. Separated from incompatible materials (see Chemical Dangers). Cool. Keep in the dark. Well closed. Store only if stabilized.

International Chemical Safety Cards BUTYL ACRYLATE ICSC: 0400 I M P O R T A N T D A T A PHYSICAL STATE; APPEARANCE: COLOURLESS LIQUID. PHYSICAL DANGERS: Vapours are uninhibited and may polymerize, blocking vents. CHEMICAL DANGERS: The substance will polymerize violently due to warming under the influence of light, peroxides and reducing agents with fire or explosion hazard. Reacts violently with strong oxidants causing fire and explosion hazard. OCCUPATIONAL EXPOSURE LIMITS (OELs): TLV (as TWA): 10 ppm; 52 mg/m3 (ACGIH 1994-1995). MAK: 10 ppm; 55 mg/m3; S (1992). ROUTES OF EXPOSURE: The substance can be absorbed into the body by inhalation and through the skin. INHALATION RISK: A harmful contamination of the air can be reached rather quickly on evaporation of this substance at 20°C. EFFECTS OF SHORT-TERM EXPOSURE: The substance irritates the eyes, the skin and the respiratory tract. Inhalation of the substance may cause lung oedema (see Notes). EFFECTS OF LONG-TERM OR REPEATED EXPOSURE: Repeated or prolonged contact may cause skin sensitization. PHYSICAL PROPERTIES Boiling point: 145-149°C Melting point: -64°C Relative density (water = 1): 0.899 Solubility in water, g/100 ml: 0.14 Vapour pressure, kPa at 20°C: 0.43 Relative vapour density (air = 1): 4.42 Flash point: 37°C Auto-ignition temperature: 267°C Explosive limits, vol% in air: 1.3-9.9% Octanol/water partition coefficient as log Pow: 2.38

ENVIRONMENTAL DATA	The substance is toxic to aquatic organisms.
N O T E S
Other boiling points 138°C and 127°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. An added stabilizer or inhibitor can influence the toxicological properties of this substance, consult an expert. Hydroquinone and hydroquinone ethyl ether are the commonly used stabilizers.
