Definition
ChEBI: A quinoline that is 1,2-dihydroquinoline bearing three methyl substituents at position 2, 2 and 4 as well as an ethoxy substituent at position 6.
General Description
Clear light yellow to dark brown viscous liquid. Discolors and stains badly. Mercaptan-like odor.
Reactivity Profile
ETHOXYQUIN(91-53-2) may undergo a hazardous polymerization at temperatures above 320° F. Tends to polymerize and darken in color on exposure to light and air. Not compatible with oxidizing agents and with strong acids .
Air & Water Reactions
Polymerizes and darkens in color on exposure to light and air. Insoluble in water.
Hazard
Toxic by ingestion.
Potential Exposure
Quinoline insecticide, fungicide and plant growth regulator. Also and ingredient in other products. Used for preharvest or postharvest preservation of color in apples and pears. It is used as an anti-oxidant to preserve color in paprika and ground and powdered chili. Ethoxyquin also is a chemical preservative used in animal feed to prevent ingredients from reacting with oxygen and becoming rancid. It has been known to cause birth defects in pet birds and dogs
Fire Hazard
This chemical is combustible.
First aid
If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions) if breathing has stopped, and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit
Shipping
UN3082 Environmentally hazardous substances, liquid, n.o.s., Hazard class: 9; Labels: 9-Miscellaneous hazardous material, Technical Name Required
Incompatibilities
Polymerization can occur on contact with strong light and/or water. Decomposes in temperatures above 150℃. Keep away from oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); strong acids.
Waste Disposal
Do not discharge into drains or sewers. Dispose of waste material as hazardous waste using a licensed disposal contractor to an approved landfill. Consult with environmental regulatory agencies for guidance on acceptable disposal practices. If allowed, Incineration with effluent gas scrubbing is recommended. Containers must be disposed of properly by following package label directions or by contacting your local or federal environmental control agency, or by contacting your regional EPA office
