226 ISOPROPYL PERCARBONATE
ISOPROPYL PERCARBONATE
Chemical Designations - Synonyms: Diisopropyl percarbonate; Diisopropyl peroxydicarbonate;
Isopropyl peroxydicarbonate; Peroxydicarbonic acid, bis (1 -methylethyl) ester; Peroxydicarbonic acid,
diisopropyl ester; Chemical Fonnula: C,H,OOCOOCOOC,H,.
Observable Characteristics - Physical State (as shipped): Solid (containers packed in “Dry Ice”);
Color: White; Odor: Disagreeable; pungent.
Physical and Chemical Properties - Physical State at 15 “c and I arm. : Liquid; Molecular Weiglzc:
206.2; Boiling Point at I aim. : Not pertinent (decomposes); Freezing Point: 46 - 50, 8 - 10,281 - 283;
Critical Temperature: Not pertinent; Critical Pressure: Not pertinent; Specific Gravity: 1.08 at 15 “C
(solid); Vapor (Gas) Specific Gravity: Not pertinent; Ratio of Specific Heats of Vapor (Gas): Not
pertinent; Latent Heat of Vaporization: Not pertinent; Heat of Combustion: -8,500, -4,720, -198; Heat
of Decomposition: -670, -370, -15.5.
Health Hazards Information - Recommended Personal Protective Equipment: Rubber gloves and
shoes; hard hat; chemical splash goggles; plastic apron; respirator (depending on solvent used);
Symptoms Following Exposure: Inhalation overexposure unlikely, but prolonged exposure may cause
lung edema. Contact with eyes may cause irritation. Solutions are severe primary skin irritants; General
Treatment for fiposure: INHALATION: move to uncontaminated atmosphere; if breathing is difficult,
give oxygen. EYES: flush with copious amounts of water. SKIN: wash off with isopropyl alcohol and
water; call a physician; Toxicity by Inhalation (ThresholdLimit Value): Data not available; Shorc-Tern
Inhalation Limits: Data not available; Toxicity by Ingestion: Grade 2, LD, 0.5-5 glkg; Late Toxicity:
Data not available; Vapor (Gas) Irritant Characteristics: Data not available; Liquid or Solid Irritant
Characteristics: Data not available; Odor Threshold: Data not available.
Fire Hazards - Flash Point : Not pertinent. This is a combustible solid; Flummable Limits in Air (W):
Not pertinent; Fire Extinguishing Agents: Water; Fire Extinguishing Agents Not To Be Used: All
extinguisbg agents may be ineffective; Special Hazarak of Combustion Products: Flammable and toxic
vapors are formed in fires, including acetone, isopropyl alcohol, acetaldehyde, and ethane; Behavior
in Fire: This product undergoes auto-accelerated decomposition and can self-ignite. Fires are very
difficult to extinguish because air is not needed for combustion; Ignition Temperature : No data;
Electrical Hazard: Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: May
decompose with the formation of oxygen when in contact with metals; Stability During Transport:
Unstable at temperatures above 0 of with the formation of oxygen gas; Neutralizing Agents for Acids
and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor ofPolymrimtion: Not pertinent.
