• Inhalation Risk: Evaporation at 20 °C is negligible; a harmful concentration of airborne particles can, however, be reached quickly.
• Effects of Short Term Exposure: The aerosol is irritating to the eyes, skin and respiratory tract.
• Uses: 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. 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 . 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.

A practical method for the reductive cleavage of the sulfide bond in xanthates

10.1016/0040-4039(96)01253-1

The research describes a practical method for the reductive cleavage of the sulfide bond in xanthates, with the purpose of removing the xanthate group from various synthetic targets that do not contain sulfur. The process involves heating xanthates in 2-propanol in the presence of equimolar amounts of dilauroyl peroxide, which is added in small portions. This method is advantageous because it does not require high dilution or slow addition of reagents, unlike traditional stannane-based radical reactions. The study concludes that this approach is efficient, particularly for secondary xanthates, and demonstrates tolerance to a variety of functional groups commonly encountered in organic synthesis. However, limitations were observed with primary xanthates, where large amounts of peroxide were needed and yields were poor.
