3173-53-3(Hazardous Substances Data) |
| Hazard Information | Back Directory | [General Description]
A yellowish liquid with an irritating odor. Insoluble in water. Flash point 127°F. Very toxic by inhalation, skin absorption and ingestion. Used to make pharmaceuticals and agricultural chemicals. | [Reactivity Profile]
Isocyanates and thioisocyanates are incompatible with many classes of compounds, reacting exothermically to release toxic gases. Reactions with amines, aldehydes, alcohols, alkali metals, ketones, mercaptans, strong oxidizers, hydrides, phenols, and peroxides can cause vigorous releases of heat. Acids and bases initiate polymerization reactions in these materials. Some isocyanates react with water to form amines and liberate carbon dioxide. Base-catalysed reactions of isocyanates with alcohols should be carried out in inert solvents. Such reactions in the absence of solvents often occur with explosive violence [Wischmeyer 1969]. | [Air & Water Reactions]
Flammable. Insoluble in water. Reacts slowly with water to form the amine and CO2. | [Health Hazard]
TOXIC; inhalation, ingestion or contact (skin, eyes) with vapors, dusts or substance may cause severe injury, burns or death. Bromoacetates and chloroacetates are extremely irritating/lachrymators. Reaction with water or moist air will release toxic, corrosive or flammable gases. Reaction with water may generate much heat that will increase the concentration of fumes in the air. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may be corrosive and/or toxic and cause pollution. | [Potential Exposure]
The material is used in the synthesis
of agricultural chemicals. | [Fire Hazard]
HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors form explosive mixtures with air: indoors, outdoors and sewers explosion hazards. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapors may travel to source of ignition and flash back. Substance will react with water (some violently) releasing flammable, toxic or corrosive gases and runoff. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated or if contaminated with water. | [Shipping]

ChEBI: An isocyanate comprising a cyclohexane core with a single isocyanato substituent. | [First aid]
If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least30 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Medical observation is recommended for 24-48 h afterbreathing overexposure, as pulmonary edema may bedelayed. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a corticosteroid spray. | [storage]
Color Code—Red: Flammability Hazard: Store ina flammable liquid storage area or approved cabinet awayfrom ignition sources and corrosive and reactive materials.Color Code—Blue: Health Hazard/Poison: Store in a securepoison location. Prior to working with cyclohexyl isocyanate you should be trained on its proper handling and storage. Cyclohexyl isocyanate must be stored to avoid contactwith moisture and temperatures above 93℃, since violentreactions occur. Store in tightly closed containers in a cool,well-ventilated area away from water, strong bases, alcohol,metal compounds, or surface-active materials. Use onlynonsparking tools and equipment, especially when openingand closing containers of this chemical. Sources of ignition,such as smoking and open flames, are prohibited where thischemical is used, handled, or stored in a manner that couldcreate a potential fire or explosion hazard | [Incompatibilities]
Cyclohexyl isocyanate polymerize due toheating above 93℃/200°F and under the influence of various chemicals including organometallic compounds.Cyclohexyl isocyanate decomposes in fire, forming toxichydrogen cyanide and nitrogen oxides fumes. Reacts withoxidizers, strong bases, water, alcohol, acids, amines, metalcompounds, surface-active materials |
