Isobutyl chloroformate Chemical Properties,Uses,Production

Chemical Properties

clear liquid

Chemical Properties

A combustible, colorless to light-colored liquid.

Uses

Peptide reagent.

General Description

A colorless to light-colored liquid. Insoluble in water and denser than water. Very corrosive to skin, eyes, and mucous membranes. Very toxic by ingestion, inhalation and skin absorption. Combustible.

Air & Water Reactions

Highly flammable. Insoluble in water. Reacts with moisture in the air to produce highly corrosive and toxic fumes of hydrogen chloride gas. Decomposes exothermically in water.

Reactivity Profile

Isobutyl chloroformate is incompatible with water, with strong oxidizing agents, alcohols, bases (including amines). May react vigorously or explosively if mixed with diisopropyl ether or other ethers in the presence of trace amounts of metal salts [J. Haz. Mat., 1981, 4, 291].

Hazard

Flammable. Corrosive.

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.

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.

Potential Exposure

This is a high volume chemical with production exceeding 1 million pounds annually in the U.S . No specific use found

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, including resuscitation mask) 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. Rinse out mouth and do not induce vomiting. Medical observation is recommended for 24 to 48 hours after breathing overexposure, as pulmonary edema may be delayed. Rest and medical observation is essential. As first aid for pulmonary edema, a doctor or authorized paramedic may consider administering a drug or other inhalation therapy

Purification Methods

It can be dried over CaCl2 and fractionated at atmospheric pressure while keeping moisture out. Its purity can be checked by conversion to the phenyl urethane derivative with PhNCO [Saunders et al. J Am Chem Soc 73 3796 1951.] IR: 1780cm-1 [Thompson & Jameson Spectrochim Acta 13 236 1959, R.se JustusLiebigs Ann Chem 205 227 1880]. [Beilstein 3 IV 26.]

Incompatibilities

Incompatible with oxidizers (chlorates, nitrates, peroxides, permanganates, perchlorates, chlorine, bromine, fluorine, etc.); contact may cause fires or explosions. Keep away from alkaline materials, strong bases, strong acids, oxoacids, epoxides, alcohols, ethers, amines. Forms explosive mixture with air above flash point (27C). Compounds of the carboxyl group react with all bases, both inorganic and organic (i.e., amines) releasing substantial heat, water and a salt that may be harmful. Incompatible with arsenic compounds (releases hydrogen cyanide gas), diazo compounds, dithiocarbamates, isocyanates, mercaptans, nitrides, and sulfides (releasing heat, toxic and possibly flammable gases), thiosulfates and dithionites (releasing hydrogen sulfate and oxides of sulfur). Decomposes exothermically in water. Reacts with moisture in air to produce highly corrosive and toxic fumes of hydrogen chloride gas

Waste Disposal

Disposal of unused product must be undertaken by qualified personnel who are knowledgeable in all applicable regulations and follow all pertinent safety precautions including the use of appropriate protective equipment. For proper handling and disposal, always comply with federal, state, and local regulations.
