Basic Info

What is 3-Chloroperoxybenzoic Acid?

3-Chloroperoxybenzoic acid (m-CPBA) is a carboxylic acid derivative, a white powder crystal, almost insoluble in water, conveniently soluble in ethanol, ether, soluble in chloroform, dichloroethane. Steady to warm, the annual disintegration price is listed below 1% at room temperature level. Disintegration rate is accelerated in liquid state.

In a polyethylene container, include 1.5 g of magnesium sulfate heptahydrate, 36g of sodium hydroxide, 360ml of water, 90ml of 30% hydrogen peroxide, 450ml of dioxane as well as ice cubes, reduced the temperature level to 15 ° C, as well as include 52.5 g of M-chlorobenzoyl chloride, after that include ice to keep the temperature level listed below 25 ° C. After reacting for 15 mins, include 900ml of 20% chilly sulfuric acid. After standing still, the organic layer was divided, filteringed system, and the filtrate was evaporated to eliminate the solvent (high vacuum cleaner distillation) to get 51g of 3-chloroperbenzoic acid.

3-Chloroperoxybenzoic acid is an oxidant generally made use of in natural synthesis. It can oxidize alkenes, carbonyl substances, nitrogen, sulfur, phosphorus, selenium, iodine substances, imines, alkanes, energetic methylene, enol silanes, and so on, Commonly used in chemical, pharmaceutical, agricultural chemicals and other areas.

3-Chloroperoxybenzoic Acid Uses

3-Chlorobenzoic acid is frequently made use of for dual bond epoxidation, nitridation, cyclization, Bayer Villiger oxidation, and N-oxidation. It can additionally be utilized as an oxidant for great chemicals such as synthetic drugs and pesticides. Often it is likewise made use of as a whitening agent.

  1. Used for cyclization responses, Bayer Villiger reactions, N-oxidation reactions, and S-oxidation reactions.
  2. Used as an oxidant for fine chemical items such as miracle drugs as well as pesticides.
  3. Used as an oxidant and bleach.
  4. As a great electrophilic reagent, it can react with numerous practical teams and oxidize olefins, enol methyl silyl ethers, furans, sulfides, selenides, as well as amino compounds.

Application of 3-Chloroperoxybenzoic Acid

CN201710478721.7 discloses a synthesis process of minoxidil. Minoxidil can directly act on the blood vessel wall, dilate small arteries, reduce peripheral resistance, lower blood pressure, and increase heart rate and cardiac output, but its The antihypertensive effect is more significant and lasting than that of hydralazine. The process is as follows: First, 2,4-diamino-6-chloropyrimidine is oxidized with m-chloroperoxybenzoic acid to obtain intermediate 2,6-diamino-4-chloropyrimidine-1-oxide, and then intermediate 2,6- Diamino-4-chloropyrimidine-1-oxide and piperidine are condensed into crude minoxidil under alkaline conditions, and finally the crude minoxidil is crystallized in isopropanol and purified to obtain refined minoxidil I finished. The process principle of the invention is simple, the operation is convenient, the product yield is high, and the purity is good.

Epoxy can be polymerized to form a cured product with excellent electrochemical, heat and humidity resistance. Among them, the polymer formed by polymerization of diepoxide as a key intermediate can be widely used in resists, coating agents, inks, adhesives, sealants, encapsulants, composite materials, optical materials, electronic materials, etc. multiple fields. CN201911328227.8 discloses a method for preparing diepoxides in one pot. The method comprises the following steps: S1. Epoxidation reaction: at low temperature, add diolefins into the reactor, slowly add m-chloroperoxybenzoic acid solution dropwise, and react to obtain the crude product solution of diepoxide; S2. Separation and purification: adding a reducing agent aqueous solution to the crude solution of the diepoxide, performing a reduction reaction, extracting and separating the organic phase, neutralizing the reaction, extracting and separating the organic phase, washing with water, removing water, filtering, and distilling the filtrate under reduced pressure to obtain the diepoxide. The present invention avoids the solvent distilled out by high vacuum in the traditional process, does not need to separate the solid raw material of m-chloroperoxybenzoic acid, and obtains diepoxide through one-pot reaction of diene and m-chloroperoxybenzoic acid solution, which reduces the process operation Difficulty increases safety, and the purity of the prepared diepoxide is over 91%, and the yield is over 95%, which is beneficial to large-scale industrial production.
