Dilauroyl peroxide Usage And Synthesis
- Chemical Propertieswhite powder
- Chemical PropertiesDilauroyl 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 .
- UsesDilauroyl 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 .
- UsesLauroyl peroxide is used as an initiatorfor free-radical polymerization in makingpolyvinyl chloride. Lauroyl peroxide constitutesabout 4% of all organic peroxides consumptionin the United States.
- General DescriptionA 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 ReactionsHighly flammable. Insoluble in water.
- Reactivity ProfileDilauroyl 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 HazardContact with liquid irritates eyes and skin. Ingestion causes irritation of mouth and stomach.
- Health HazardLauroyl 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.
- Fire HazardBehavior 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.
- CarcinogenicityThe 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.
- storageStore 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.
- Purification MethodsCrystallise it from n-hexane or *benzene and store it below 0o. Potentially EXPLOSIVE. [cf Beilstein 2 IV 1102.]
- Waste DisposalAlthough lauroyl peroxide is relatively lesshazardous, it is recommended that to handlespills and disposal, the same safety measuresbe followed as those for other hazardousorganic peroxides.
