| Application | The double lauryl peroxide is mainly used as a free radical polymerization initiator, and can also be used as a polyester curing agent, rubber crosslinking agent, foaming agent, bleach, desiccant, etc. It is used as an efficient initiator for polyvinyl chloride and high pressure polyethylene. It is also used as a bleaching agent in the food industry and in the production of fats and oils. It is obtained from the reaction of dodecyl chloride with hydrogen peroxide. used as initiator for high-pressure polyethylene and bleaching agent for food high-efficiency initiator for polyvinyl chloride and high-pressure polyethylene, often used in combination with initiator a (di-tert-butyl peroxide). It is used as a bleaching agent in the food industry and in the production of oils and fats. This product is the first level of organic oxidants, storage cover with water. efficient initiator for polyvinyl chloride, high pressure polyethylene; Often used in combination with initiating Agent A (di-tert-butyl peroxide). It is used as a bleaching agent in the food industry and in Stain and grease. This product is a first-class organic oxidant, and is covered with water during storage. |
| production method | is derived from the reaction of dodecanoyl chloride (see above) with hydrogen peroxide. Dodecanoyl chloride was dissolved in petroleum ether, sodium hydroxide was added, and then oxidized with 6% hydrogen peroxide. When the temperature rose to 45 ° C., ice water was added to the reaction mixture to cool the reaction mixture under vigorous stirring, and the crystals were filtered with stirring, washed to neutrality, and dried to obtain the final product. Purposes: polyvinyl chloride, high-pressure polyethylene efficient initiator; Often with the initiating Agent A (di-tert-butyl peroxide) and. It is used as a bleaching agent in the food industry and in Stain and grease. This product is a first-class organic oxidant, and is covered with water during storage. obtained by the reaction of dodecyl chloride with hydrogen peroxide.
