Chemische Eigenschaften
Dilauroyl peroxide (Lauroyl peroxide) is a tasteless, coarse, white powder. Dilauroyl peroxide is not a deflagration hazard. However, it has been judged an intermediate fire hazard by Noller et al. When all the physical tests available for this peroxide are evaluated collectively, it actually ranks as a low physical hazard .
Verwenden
Lauroyl peroxide acts as a bleaching agent, drying agent for fats, oils and waxes. Further, it serves as a polymerization initiator as well as vulcanizing agent. In addition to this, it plays an important role for high-pressure polyethylene and food used in bleaching agent.
Verwenden
Lauroyl peroxide is used as an initiatorfor free-radical polymerization in makingpolyvinyl chloride. Lauroyl peroxide constitutesabout 4% of all organic peroxides consumptionin the United States.
Verwenden
Dilauroyl peroxide is produced by reaction of lauroyl chloride with sodium peroxide. Its major use is as an initiator for vinyl chloride. It is used as a polymerization agent in the plastics industry and as a curing agent for rubber. It has also been used as a burnout agent for acetate yarns. The pharmaceutical industry uses it in topical creams in combination with antibiotics for acne treatment .
synthetische
Dilauroyl peroxide is the symmetrical peroxide of lauric acid. It is produced by treating lauroyl chloride with hydrogen peroxide in the presence of base:
2C11H23COCl + H2O2+ 2NaOH → (C11H23CO2)2 + 2HCl
Definition
ChEBI: Lauroyl peroxide is a dicarboxylic acid.
Allgemeine Beschreibung
Dilauroyl peroxide appears as a white solid with a faint soapy odor. Less dense than water and insoluble in water. Hence floats on water. Melting point 49 °C. Toxic by ingestion and inhalation. Strong skin irritant. Used as bleaching agent, drying agent for fats, oils and waxes, and as a polymerization catalyst.
Air & Water Reaktionen
Highly flammable. Insoluble in water.
Reaktivität anzeigen
Dilauroyl peroxide is an oxidizing agent. Can ignite organic materials; hence a dangerous fire and explosion risk [Hawley]. Strongly reduced material such as sulfides, nitrides, and hydrides may react explosively. Vigorous reactions with other reducing agents. With charcoal sometimes ignites. [Bretherick, 5th ed., 1995, p. 1194].
Health Hazard
Contact with liquid irritates eyes and skin. Ingestion causes irritation of mouth and stomach.
Health Hazard
Lauroyl peroxide is a mild eye irritant; theirritation from 500 mg/day in rabbits’ eyeswas mild. It is nontoxic. Prolonged exposureto laboratory animals caused tumors at thesite of application. However, the evidence ofcarcinogenicity in animals is inadequate todate.
Brandgefahr
Behavior in Fire: Can increase the severity of a fire. Becomes sensitive to shock when hot. Containers may explode in a fire. May ignite or explode spontaneously if mixed with flammable materials.
Flammability and Explosibility
Not classified
Carcinogenicity
The International Agency for Research on Cancer has evaluated the carcinogenicity of lauroyl peroxide. They classified it as a Group 3 material, which means there is limited or inadequate evidence for animals and inadequate or absent information for humans . The carcinogenicity of this peroxide has primarily been studied using skin applications. After a single topical application of 10, 20, or 40 mg of lauroyl peroxide, the epidermal thickness increased markedly. This hyperplasia was characterized by a sustained production of dark basal keratinocytes. This peroxide is inactive as a tumor initiator or as a complete carcinogen. However, it is as effective as benzoyl peroxide as a skin tumor promoter.
Lager
Store in a well-ventilated, cool area, isolatedfrom other chemicals. It is shippedin fiber drums not exceeding 100 lb. Smallamounts may be shipped in 1-lb fiberboardboxes.
läuterung methode
Crystallise it from n-hexane or *benzene and store it below 0o. Potentially EXPLOSIVE. [cf Beilstein 2 IV 1102.]
Waste disposal
Although lauroyl peroxide is relatively lesshazardous, it is recommended that to handlespills and disposal, the same safety measuresbe followed as those for other hazardousorganic peroxides.
