Description
Ethylbenzyltoluidine is a yellowish to lightbrown liquid with an unpleasant odor. Boilingpoint = 230℃; Flash point = 167℃. Insoluble in water.
Chemical Properties
Yellow - light brown liquid.
Uses
Ethylbenzyltoluidine can be used as an intermediate for acid blue 90, 91, 109 and other dyes.
Synthesis
The ratio of N-ethyl-m-toluidine to benzyl chloride is 1: (0.95~1.05) (molar ratio), and Ethylbenzyltoluidine can be obtained after reaction.
Potential Exposure
This compound is used in dyesynthesis
First aid
Eye Contact: Immediately remove any contactlenses and flush with large amounts of water for at least 15 min, occasionally lifting upper and lower lids. Seek medical attention immediately.Skin Contact: Quickly remove contaminated clothing.Immediately wash area with large amounts of soap andwater. Seek medical attention if symptoms develop andremove the person from exposure. Begin rescue breathing(using universal precautions, including resuscitation mask)if breathing has stopped and CPR if heart action hasstopped. Transfer promptly to a medical facility.Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobinemia in urine.
storage
Color Code—Blue: Health Hazard/Poison: Storein a secure poison location. Prior to working with thischemical you should be trained on its proper handling andstorage. Store in tightly closed containers in a cool, well-ventilated area away from oxidizers and light. Where possible, automatically pump liquid from drums or other storagecontainers to process containers
Shipping
This compound requires a shipping label of“POISONOUS/TOXIC MATERIALS.” It falls in HazardClass 6.1 and Packing Group III.
Incompatibilities
Strong oxidizers.
Short Term Exposure
Exposure can interfere with the ability of the blood to carry oxygen (methemoglobinemia),causing headaches, dizziness, weakness, a bluish skin color,and even death. This substance can damage the kidneys andbladder, causing painful, bloody urine. Eye contact causesirritation and can lead to permanent damage. Skin contactcan cause a rash and burning feeling
Personal Protective Methods
Wear protective gloves andclothing to prevent any reasonable probability of skin contact. Safety equipment suppliers/manufacturers can providerecommendations on the most protective glove/clothingmaterial for your operation. All protective clothing (suits,gloves, footwear, headgear) should be clean, available eachday, and put on before work. Contact lenses should not beworn when working with this chemical. Wear splash-proofchemical goggles and face shield unless full face-piecerespiratory protection is worn. Employees should washimmediately with soap when skin is wet or contaminated.Provide emergency showers and eyewash
Fire Extinguishing
Ethylbenzyltoluidine may burn butdoes not readily ignite. Poisonous gases are produced infire. Use dry chemical, carbon dioxide, or alcohol foamextinguishers. Vapors in confined areas may explode whenexposed to fire. Containers may explode in fire. Storagecontainers and parts of containers may rocket great distances, in many directions. If material or contaminated runoff enters waterways, notify downstream users ofpotentially contaminated waters. Notify local health and fireofficials and pollution control agencies. From a secure,explosion-proof location, use water spray to cool exposedcontainers. If cooling streams are ineffective (venting soundincreases in volume and pitch, tank discolors, or shows anysigns of deforming), withdraw immediately to a secure position. If employees are expected to fight fires, they must betrained and equipped in OSHA 1910.156. The only respirators recommended for firefighting are self-contained breathing apparatuses that have full face-pieces and are operatedin a pressure-demand or other positive-pressure mode.
