General Description
2,5-Di(tert-butylperoxy)-2,5-dimethyl-3-hexyne is particularly sensitive to temperature rises and contamination. Above a given "Control Temperature" they decompose violently. 2,5-Di(tert-butylperoxy)-2,5-dimethyl-3-hexyne is generally stored or transported as a mixture, with an inert solid.
Reactivity Profile
Peroxides, such as 2,5-BIS(TERT-BUTYLPEROXY)-2,5-DIMETHYL-3-HEXYNE, are good oxidizing agents. Organic compounds can ignite on contact with concentrated peroxides. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively with peroxides. There are few chemical classes that do not at least produce heat when mixed with peroxides. Many produce explosions or generate gases (toxic and nontoxic). Generally, dilute solutions of peroxides (<70%) are safe, but the presence of a catalyst (often a transition metal such as cobalt, iron, manganese, nickel, or vanadium) as an impurity may even then cause rapid decomposition, a buildup of heat, and even an explosion. Solutions of peroxides often become explosive when evaporated to dryness or near-dryness. Danger of explosion when dry. May explode from heat, shock, friction or contamination. May ignite combustibles (wood, paper, oil, clothing, etc.). May be ignited by heat, sparks or flames.
Flammability and Explosibility
Notclassified
Check Digit Verification of cas no
The CAS Registry Mumber 1068-27-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,0,6 and 8 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 1068-27:
(6*1)+(5*0)+(4*6)+(3*8)+(2*2)+(1*7)=65
65 % 10 = 5
So 1068-27-5 is a valid CAS Registry Number.
