105-64-6 Usage
Chemical Properties
White crystalline solid with a mild characteristicodor; mp 8–10°C (46.4–50°F); density1.080 at 15°C (59°F); slightly soluble inwater, 0.04% at 25°C (77°F), soluble in ether,chloroform, benzene, hexane, and isooctane.
Uses
It is used as a catalyst to initiate polymerizationreactions to produce polymers fromethylene, styrene, vinyl acetate, vinyl chloride,and vinyl esters. Polymers of increasedlinearity and better properties can be obtainedby optimizing its concentration, temperature,and pressure conditions.

General Description
A white solid (shipped packed in Dry Ice to stabilize) with a sharp unpleasant odor. Insoluble in sater and sinks in water. Used as polymerization catalyst.
Air & Water Reactions
Highly flammable. Insoluble in water. Spontaneous decomposition at room temperature releases flammable toxic products.
Reactivity Profile
ISOPROPYL PEROXYDICARBONATE decomposes violently or explosively at temperatures 0-10°C owing to self- accelerating exothermic decomposition; Several explosions were due to shock, heat, or friction; amines and certain metals can cause accelerated decomposition [Bretherick 1979 p. 156]. Spontaneous decomposition possible at room temperature to release flammable and corrosive products (presence of stabilizer reduces this possibility). A strong oxidizing agent. May ignite organic compounds on contact, hence a fire risk. Strongly reduced material such as sulfides, nitrides, and hydrides can react explosively. Reacts at least to produce heat when mixed with members of most chemical classes. These reactions often generate gases (toxic and nontoxic). Subject to decomposition, buildup of heat and even an explosion if contaminated with a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium or a salt of a transition metal).
Health Hazard
Different sources of media describe the Health Hazard of 105-64-6 differently. You can refer to the following data:
1. Inhalation overexposure unlikely, but prolonged exposure may cause lung edema. Contact with eyes may cause irritation. Solutions are severe primary skin irritants.
2. Diisopropyl peroxydicarbonate is a moderateskin irritant. The irritation can be severe onrabbit skin. Eye contact can cause conjunctivitisand corneal ulcerations, which, however,are fully recoverable in 1–2 weeks. Itstoxicity is very low. There is no report of itsill effect on humans. It may cause dermatitison sensitive skin.LD50 value, oral (rats): 21,410 mg/kg.
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°F with the formation of oxygen gas; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
Safety Profile
Moderately toxic by
ingestion and skin contact. A severe eye
irritant. Very dangerous fire hazard.
Dangerously unstable above 10°C. An
impactand heat-sensitive explosive.
Solutions may spontaneously explode (the
hazard increases with concentration).
Storage in sealed containers map be
dangerous. Explodes on contact with
amines or potassium iodide. May explode on
contact with organic matter. When heated to
decomposition it emits acrid smoke and
fumes. See also PEROXIDES, ORGANIC
Waste Disposal
Larger quantities can be disposed of by scatteringin a disposal area where it melts andgradually decomposes. Small quantities aredestroyed by adding slowly to 5% alcoholicKOH. Solutions in small amount may be disposedof in porous sandy soils.
Check Digit Verification of cas no
The CAS Registry Mumber 105-64-6 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 5 respectively; the second part has 2 digits, 6 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 105-64:
(5*1)+(4*0)+(3*5)+(2*6)+(1*4)=36
36 % 10 = 6
So 105-64-6 is a valid CAS Registry Number.
