15520-11-3 Usage
Chemical Properties
Different sources of media describe the Chemical Properties of 15520-11-3 differently. You can refer to the following data:
1. Colorless solid
2. Bis(4-tert-butylcyclohexyl) peroxydicarbonate is crystalline
solid (white powder) with slight odor, sensitive to heat
and contamination, and may decompose violently or
explosively at temperature 0–10°C, owing to self-accelerating
exothermic decomposition due to shock, heat, or
friction. To lessen the explosion risk, di-(4-tert-butylcyclohexyl)
peroxydicarbonate should be stored in a temperature
controlled vessel and mixed with water to form a
slurry of the peroxide. Hazardous polymerization does
not occur (12c). Detached storage is preferred for this
chemical, including out of direct sunlight in a cool wellventilated
place. It should be stored away from combustibles
and other incompatible materials, including strong
acids, bases, oxidizers, reducing agents, amines, and promoters/
accelerators, which may result in a violent decomposition
or explosion. Refer to the Code for the Storage of
Organic Peroxide Formulations (13a).
Uses
Different sources of media describe the Uses of 15520-11-3 differently. You can refer to the following data:
1. Bis(4-(tert-butyl)cyclohexyl) Peroxydicarbonate is a useful raw material used in the preparation of polymerizable yellow azo dyes applied in artificial intraocular lens. A catalyst.
2. Di-(4-tert-butylcyclohexyl) peroxy dicarbonate is used as
polymerization initiator. No information was located for this
compound.
General Description
Crystalline solid. Bis(4-tert-butylcyclohexyl) peroxydicarbonate is particularly heat and contamination sensitive. These materials above a given "control temperature" may decompose violently. They are often stored in a temperature controlled vessel, also mixed with water to form a slurry of the peroxide. This greatly lessens the explosion hazard risk.
Reactivity Profile
DI-(4-TERT-BUTYLCYCLOHEXYL)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].
Check Digit Verification of cas no
The CAS Registry Mumber 15520-11-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,5,5,2 and 0 respectively; the second part has 2 digits, 1 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 15520-11:
(7*1)+(6*5)+(5*5)+(4*2)+(3*0)+(2*1)+(1*1)=73
73 % 10 = 3
So 15520-11-3 is a valid CAS Registry Number.
