Chemical Properties
This peroxide powder with 8.45% active oxygen and 82%
purity was mixed 20% in water and showed small pressure
rises in the time–pressure assay when using 1 g of
igniter. This indicates that this material poses a deflagration
hazard.
General Description
Crystalline solid mixed with water. Water lessens the explosion hazard.
Reactivity Profile
Peroxides, such as DI-(TERT-BUTYLPEROXY)PHTHALATE, 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.
Purification Methods
Crystallise the perphthalate from Et2O or pet ether and dry it over H2SO4. The IR has max 1772cm-1 in CCl4. [Milas & Surgemor J Am Chem Soc 68 642 1946, Milas & Kelin J Org Chem 36 2900 1971, Beilstein 9 III 4190, 9 IV 3260.] Potentially EXPLOSIVE.
Check Digit Verification of cas no
The CAS Registry Mumber 2155-71-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,1,5 and 5 respectively; the second part has 2 digits, 7 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 2155-71:
(6*2)+(5*1)+(4*5)+(3*5)+(2*7)+(1*1)=67
67 % 10 = 7
So 2155-71-7 is a valid CAS Registry Number.

Temperature-controlled solvent-free selective synthesis of tert-butyl peresters or acids from benzyl cyanides in the presence of the TBHP/Cu(OAc)2 system

Solvent-free room temperature synthesis of tert-butyl peresters was achieved via copper-catalyzed oxidative-coupling of benzyl cyanides with tert-butyl hydroperoxide in short reaction times. Various derivatives of tert-butyl peresters were synthesized by this pathway in good to excellent yields. Further investigation revealed that the above-mentioned protocol is effective for the synthesis of benzoic acid derivatives when the reaction is conducted at 80?°C, under the same reaction conditions.
Continuous manufacture of peroxyesters
-
, (2008/06/13)
A continuous solvent-free process for the manufacturing of peroxyesters from an acid chloride, a hydroperoxide and an alkali metal hydroxide generates a pure product of good quality, high yields and throughput per unit volume of the reactor. The process comprises at least two reactors and a physical separation unit for separating the high purity product.
