N,N-DIMETHYLCYCLOHEXYLAMINE ICSC: 1444 Cyclohexylamine, N,N-dimethyl- Cyclohexyldimethylamine N,N-Dimethylaminocyclohexane C8H17N Molecular mass: 127.26 ICSC #    1444 CAS #     98-94-2 RTECS # GX1198000 UN #        2264 Types of Hazard/ Exposure Acute Hazards/ Symptoms Prevention First Aid/ Fire Fighting FIRE Flammable. Gives off irritating or toxic fumes (or gases) in a fire. NO open flames, NO sparks, and NO smoking. Powder, alcohol-resistant foam, water spray, carbon dioxide. Explosion Above 42.2°C explosive vapour/air mixtures may be formed. Above 42.2°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! AVOID ALL CONTACT! IN ALL CASES CONSULT A DOCTOR!  •Inhalation Sore throat. Burning sensation. Cough. Laboured breathing. Shortness of breath. Symptoms may be delayed (see Notes). Ventilation, local exhaust, or breathing protection. Fresh air, rest. Half-upright position. Artificial respiration may be needed. Refer for medical attention.  •Skin Redness. Pain. Skin burns. Protective gloves. Protective clothing. First rinse with plenty of water, then remove contaminated clothes and rinse again. Refer for medical attention.  •Eyes Redness. Pain. Severe deep burns. Face shield, 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 Burning sensation. Abdominal pain. Shock or collapse. Do not eat, drink, or smoke during work. Rinse mouth. Give plenty of water to drink. Do NOT induce vomiting. Refer for medical attention. Spillage Disposal Storage Packaging & Labelling Collect leaking liquid in sealable containers. Carefully collect remainder, then remove to safe place. Do NOT let this chemical enter the environment. (Extra personal protection: filter respirator for organic gases and vapours.) Fireproof. Separated from strong acids, food and feedstuffs . Do not transport with food and feedstuffs. UN Hazard Class: 8 UN Subsidiary Risks: 3 UN Packing Group: II N,N-DIMETHYLCYCLOHEXYLAMINE ICSC: 1444 Important Data Physical State; Appearance: COLOURLESS LIQUID Physical Dangers: Chemical Dangers: The substance decomposes on burning producing toxic fumes including nitrogen oxides . The substance is a medium strong base. Occupational Exposure Limits: TLV not established. Routes of Exposure: The substance can be absorbed into the body by inhalation, through the skin and by ingestion. Inhalation Risk: No indication can be given about the rate in which a harmful concentration in the air is reached on evaporation of this substance at 20°C. Effects of Short-Term Exposure: The substance is corrosive to the skin, the eyes and the respiratory tract. Corrosive on ingestion. Inhalation may cause lung oedema (see Notes). The effects may be delayed. Medical observation is indicated. Effects of Long-Term or Repeated Exposure: Physical Properties Boiling point: 162-165°C Melting point: -60°C Relative density (water = 1) : 0.85 Solubility in water, g/100 ml: 20 Vapour pressure, kPa at 25°C: 0.4 Relative vapour density (air = 1): 4.4 Relative density of the vapour/air-mixture at 20°C (air = 1): 1.01 Flash point: 42.2°C c.c. Auto-ignition temperature: 215°C Explosive limits, vol% in air: 3.6-19 Octanol/water partition coefficient as log Pow: 2.01 Environmental Data The substance is harmful to aquatic organisms. N O T E S 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 is therefore essential. Immediate administration of an appropriate inhalation therapy by a doctor or a person authorized by him/her, should be considered.
