Tert-butanol peroxide is an organic peroxide. It is a colorless liquid and presents a volatile fragrance at room temperature. Tert-butanol peroxide is a strong oxidizing agent for organic substances. It can react with many substances such as alcohols, ethers, aldehydes and ketones. In the reaction, it breaks off an oxygen molecule, forms free radicals, and causes an oxidation reaction of the substance.
Tert-butanol peroxide burns well and can be used as a fuel or in oxidizing reactions in industry. It is highly oxidizing and care needs to be taken when using it to avoid reacting with flammable substances, for example. It can spontaneously combust in air, so it needs to be stored in a cool, ventilated place. Tert-Butanol peroxide can also cause violent explosive reactions and is irritating to the skin and eyes, so care needs to be taken when using it. Tert-Butanol peroxide should be stored and used away from heat and direct sunlight to avoid the risk of spontaneous decomposition or explosion. In the laboratory, it is often used diluted to attenuate its strong oxidizing and hazardous properties.
Tert-butanol peroxide is often used as an oxidizing agent in chemical synthesis, and can be used to oxidize alcohols, aldehydes, ketones and other organic substances, and in some cases can also be used as an initiator and polymerization initiator.
Introduction
Tert-butanol peroxide (t-Butyl hydroperoxide) is an organic peroxide. Tert-butanol peroxide is a colorless liquid with a pungent odor.
At room temperature, tert-butanol peroxide decomposes into alcohols and ethers to form n-butanol and ethyl tert-butyl ether. Due to its decomposition properties, tert-butanol peroxide is a strong oxidizer and is prone to spontaneous combustion or explosion. It needs to be handled with care during use and stored in fireproof cabinets.
Tert-Butanol peroxide is mainly used for oxidation reactions in organic synthesis. It can be used to oxidize alcohols, ethers, aldehydes, ketones, and organosulfur compounds. For example, tert-butanol peroxide can oxidize alcohols to the corresponding aldehydes or ketones, or aldehydes to acids. It can also be used to synthesize peroxide-based compounds such as hydrogen peroxide and peroxybenzaldehyde.
Safety Information
Tert-Butanol peroxide is an organic compound. Here is some safety information about tert-butanol peroxide:
1. TOXICITY: Tert-Butanol peroxide is highly toxic and harmful to human health. It can cause irritating and corrosive effects and damage to the eyes, skin and respiratory system.
2. Flammability: tert-Butanol peroxide is a flammable compound that burns rapidly in air and produces toxic gases when burned.
3. Storage: Tert-Butanol peroxide should be stored in a cool, well-ventilated place. Avoid contact with ignition sources, high temperature, high humidity, oxidizers and other substances. Exposure to direct sunlight and heat sources should be avoided.
4. Handling: When handling tert-butanol peroxide, wear personal protective equipment such as protective glasses, gloves and clothing. Avoid inhalation of its vapors and contact with skin. The treatment process should be carried out in a well-ventilated area to avoid the generation of dust and vapors.
5. Waste disposal: tert-butanol peroxide is a hazardous chemical and its waste should not be dumped freely. Appropriate waste disposal methods should be adopted in accordance with the requirements of local regulations and rules.
Uses
Tert-Butanol peroxide is an organic compound commonly abbreviated TBHP.It is primarily used as an oxidizing agent and free radical initiator.
Tert-butanol peroxide is used as an oxidizing agent in organic synthesis to oxidize olefins to alcohols, ketones or aldehydes. It can also be used to oxidize other organic compounds such as amines, sulfides and selenides.
Tert-butanol peroxide is also used as a free radical initiator in polymerization reactions. It can initiate free radical polymerization reactions, such as the polymerization of acrylates, butenoates and silicone monomers to prepare various polymeric materials.
Tert-Butanol peroxide is also used in industrial applications as a surface treatment agent, rubber additive and polymer cross-linking agent. In the biomedical field, it is also used as a biological reagent, such as a chemical reagent in biological deoxyribonucleic acid (DNA) sequencing.
Preparation
Tert-butanol peroxide is an organic peroxide which can be prepared by the following methods:
1. Direct oxidation of tert-butanol: tert-butanol is contacted with oxygen or air and oxidized under appropriate temperature and pressure to produce tert-butanol peroxide. The reaction conditions need to be properly controlled to avoid side reactions and the formation of over-oxidized products.
2. Peroxidation of hydroxide: tert-butanol is first reacted with an alkaline solution (e.g. sodium hydroxide or potassium hydroxide) to form the corresponding tert-butanol salt, and then peroxidized by addition of oxygen or hydrogen peroxide (H2O2) to form tert-butanol peroxide.
Tert-butanol peroxide is a strong oxidizing agent with high activity.
