80-43-3 Usage

Chemical Properties

Dicumyl peroxide is a crystalline solid that melts at 42°C. It is insoluble in water and soluble in vegetable oil and organic solvents . It is used as a high-temperature catalyst in production of polystyrene plastics. The deflagration hazard potential of this peroxide was tested using 5 g of igniter in the revised time–pressure test, but no pressure rise was produced . Noller et al. found it to be an intermediate fire hazard.

Uses

Dicumyl peroxide(DCP) is used:in vulcanization of rubber as a crosslinking agent in the synthesis of polylactic acid composite fibers in the preparation of polyethylene composites in the synthesis of polyamide 112/ethylene vinyl acetate copolymer blends.

General Description

Dicumyl peroxide is a pale yellow to white granular solid with a characteristic odor. It is used as a polymerization catalyst and vulcanizing agent.

Reactivity Profile

The explosive instability of the lower dialkyl peroxides (e.g., dimethyl peroxide) and 1,1-bis-peroxides decreases rapidly with increasing chain length and degree of branching, the di-tert-alkyl derivatives being amongst the most stable class of peroxides. Though many 1,1-bis-peroxides have been reported, few have been purified because of the higher explosion hazards compared with the monofunctional peroxides. Dicumyl peroxide is unlikely that this derivative would be particularly unstable compared to other peroxides in it's class, Bretherick 2nd ed., p 44 1979.

Flammability and Explosibility

Nonflammable

Safety Profile

Mildly toxic by ingestion. See also PEROXIDES. When heated to decomposition it emits acrid smoke and irritating fumes.

Purification Methods

Crystallise the peroxide from 95% EtOH (charcoal). Store it at 0o. Potentially EXPLOSIVE. [Beilstein 6 IV 3220.]

Check Digit Verification of cas no

The CAS Registry Mumber 80-43-3 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 0 respectively; the second part has 2 digits, 4 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 80-43:
(4*8)+(3*0)+(2*4)+(1*3)=43
43 % 10 = 3
So 80-43-3 is a valid CAS Registry Number.

ESI-MS study of copper chloride/phase-transfer catalytic systems for oxidation of cumene with 1-methyl-1-phenylethyl hydroperoxide

Gillner, Danuta,Zawadiak, Jan,Mazurkiewicz, Roman,Kurczewska, Joanna,Schroeder, Grzegorz,Orlinska, Beata

, p. 143 - 147 (2010)

Oxidation of cumene with 1-methyl-1-phenyl- ethyl hydroperoxide in the presence of copper chloride/ phase transfer catalytic systems was investigated by ESI- MS. For catalytically active copper(II) chloride/crown ethers, copper(II) chloride/crown ethers/alkaline metal salts, and copper(II) chloride/tetrabutylammonium chloride systems, the presence of a few kinds of copper complexes in the organic phase was detected by use of ESI-MS. When copper(II) chloride/podand systems were used, the conversion of hydroperoxide and the yield of oxidation product were close to zero, although the concentration of copper complexes in the organic phase was high. Addition of bis(2-hydroxyethyl) ether to the catalytically active copper(II) chloride/18-crown-6 system resulted in an inhibition effect. Springer-VerIag 2010.

Construction of starch-based bionic glutathione peroxidase and its catalytic mechanism

Jiao, Shu-Fei,Liang, Xing-Tang,Liu, Yong-Xian,Liu, Zi-Jie,Yin, Yan-Zhen,Zhang, Rui-Rui,Zheng, Yun-Ying

, (2022/02/16)

Glutathione peroxidase (GPx) is an important selenium-containing antioxidant enzyme in human body. The preparation of bionic GPx and the mimicry of its catalytic behavior are of great significance for the development of antioxidant drugs. At present, most of the reported biomimetic selenoenzymes based on the macromolecular are difficult to be degraded, which restricts their applications in the fields such as medical treatment, health care, and functional food. In order to solve this issue, herein, the octenyl succinic acid-modified starch (OSA starch) prepared by the esterification of waxy corn starch was used as the raw material, a new selenium-functionalized starch (Se-starch) was synthesized via the reaction of OSA starch and sodium hydrogen selenide. Such Se-starch, as a biomimetic selenoenzyme, was characterized using 1H NMR, EDS, XPS, SEM, XRD, and FT-IR. The Se-starch with a catalytic activity of 2.48?μM·min?1 showed a typical catalysis behavior of saturated kinetic and enzymology. This catalytic activity is 1.04 × 105 times higher than that of the PhSeSePh, a representative small molecule bionic GPx. The study of catalytic mechanism revealed that the octenyl succinate molecule bonded on the starch endowed it with hydrophobic micro-environments, which benefited the binding of hydrophobic substrates, and consequently increased the catalytic activity. This work not only provided a new idea for constructing natural polymers-based bionic GPx, but also offered an important theoretical basis for the development of new antioxidant drugs and functional foods.

Synthetic method for dialkyl peroxide

-

Paragraph 0063-0068, (2019/04/13)

The invention belongs to the technical field of chemical synthesis, and in particular relates to a synthetic method for dialkyl peroxide. The method comprises the following step: adding an alkyl alcohol compound, a compound containing a peroxide bond and a polyvinyl alcohol compound amino acid catalyst into an organic solvent to be stirred and dehydrated to react to synthesize the dialkyl peroxide, wherein the polyvinyl alcohol compound amino acid catalyst is prepared by polymerizing a spherical polyvinyl alcohol matrix and compound amino acids. In a production process of the peroxide, a chemical raw material sulfuric acid or sodium hydroxide with certain corrosion is avoided, the synthetic process of the peroxide is optimized, and the waste water discharge containing sulfuric acid or sodium hydroxide in the industrial production process is reduced.

METHOD FOR THE PRODUCTION OF PHENOL AND ACETONE

-

Page/Page column 2-3, (2008/12/08)

A method for the production of phenol and acetone from a cumene hydroperoxide mixture comprises: decomposing the cumene hydroperoxide mixture in the presence of a catalyst mixture to form a mixture comprising phenol and acetone, wherein the method further comprises: a) forming the catalyst mixture in a catalyst formation reactor by combining sulfuric acid and phenol in a weight ratio of from 2:1 to 1:1000; b) holding the catalyst mixture in the catalyst formation reactor at a temperature of about 20 to 80° C. for about 1 to 600 minutes; and c) adding the catalyst mixture to the cumene hydroperoxide mixture to form the phenol and acetone mixture. Running the process in this manner reduces the yield of hydroxyacetone and, consequently, improves the quality of the commercial phenol. Moreover, this method reduces consumption of sulfuric acid in comparison with the process in which sulfuric acid is used as catalyst.

Hydrogen abstraction from neurotransmitters by active oxygen species facilitated by intramolecular hydrogen bonding in the radical intermediates

Ohkubo, Kei,Moro-Oka, Yoshihiko,Fukuzumi, Shunichi

, p. 999 - 1001 (2007/10/03)

The reactivity of neurotransmitters toward hydrogen abstraction by an active oxygen species (the cumylperoxyl radical) is comparable to that of a strong antioxidant such as catechin due to the strong intramolecular hydrogen bonding, which has been successfully detected by ESR.
