2% 2C6-dihydroxy-3% 2C5-dimethylpyridine is an important intermediate in organic synthesis. There are various synthesis methods. The following are the common ones:
First, 2% 2C6-dihydroxypyridine is used as the starting material, and the target product can be obtained by methylation reaction. In this process, methylation reagents such as dimethyl sulfate and iodomethane can be selected to realize the substitution of methyl groups to hydrogen atoms under the catalysis of bases. Bases can be selected from potassium carbonate, sodium hydroxide, etc. The reaction is often carried out in organic solvents such as N, N-dimethylformamide (DMF), acetonitrile, etc. For example, 2% 2C6-dihydroxypyridine and potassium carbonate are placed in DMF, stirred well, dimethyl sulfate is slowly added dropwise, heated to a suitable temperature for several times, and after post-treatment, such as extraction, column chromatography, etc., 2% 2C6-dihydroxy- 3% 2C5-dimethylpyridine can be obtained.
Second, starting from 2% 2C6-dichloropyridine, first react with nucleophiles to introduce hydroxyl groups, and then methylate. 2% 2C6-dichloropyridine can be treated with sodium hydroxide aqueous solution first, so that the chlorine atom is replaced by hydroxyl groups to generate 2% 2C6-dihydroxypyridine. The following steps are the same as the above-mentioned methylation reaction using 2% 2C6-dihydroxypyridine as the raw material. This route also has practical value because the raw material 2% 2C6-dichloropyridine is relatively easy to obtain.
Third, it is synthesized by the construction reaction of pyridine rings. For example, using suitable nitrogen-containing and carbonyl-containing compounds as raw materials, pyridine rings are formed by cyclization reaction, and hydroxyl groups and methyl groups are introduced at the same time. For example, using 2-amino-3-methyl-5-hydroxybenzoic acid and ethyl acetoacetate as raw materials, under the action of acidic catalysts, through condensation, cyclization and other steps, 2% 2C6-dihydroxy-3% 2C5-dimethylpyridine is generated. This method step is slightly complicated, but the product structure can be flexibly adjusted according to the selection of raw materials.
All synthesis methods have advantages and disadvantages. In practical application, it is necessary to comprehensively consider the availability of raw materials, reaction conditions, cost and other factors to choose the most suitable method.

2% 2C6-dihydroxy-3% 2C5-di-tert-butyl-p-cresol, commonly known as BHT, is a commonly used antioxidant. This substance is white crystalline or crystalline powder at room temperature, odorless, tasteless, and gradually changes yellow in color when exposed to light.
In terms of physical properties, the melting point is 69.7 ° C, the boiling point is 265 ° C, and the relative density is 1.048 (20/4 ° C). It has good solubility and is soluble in benzene, toluene, methanol, methyl ethyl ketone, ethanol, isopropanol, petroleum ether and other organic solvents, but it is insoluble in water and water below 10 ° C. < Br >
Chemically, it has antioxidant activity. The hydrogen atom of the phenolic hydroxyl group is active and easily reacts with free radicals to convert into relatively stable free radicals, thereby terminating the chain reaction of free radicals and achieving the effect of antioxidation. It is relatively stable in the air, but when it encounters strong oxidants, the phenolic hydroxyl group will be oxidized, resulting in structural and property changes. And under acidic or alkaline conditions, the stability will be affected, and reactions such as hydrolysis and esterification can occur under specific conditions. Because it can effectively delay or inhibit the oxidative rancidity of oils and oily foods, it is widely used as an antioxidant in food, oils, cosmetics, rubber, plastics and other industries.

2% 2C6-dihydroxy-3% 2C5-dimethylpyridine, this is a special chemical substance. When using it, many precautions need to be paid attention to in detail.
It is lively. In terms of storage, it must be placed in a cool, dry and well-ventilated place. Because it may react with water vapor and oxygen in the air, if stored improperly, it is easy to deteriorate and lose its original chemical properties and efficacy.
During use, protective measures must be taken. Wear professional protective clothing, such as protective clothing and protective gloves, to avoid direct contact with the skin and prevent skin irritation and even corrosion. It is also necessary to wear protective glasses and suitable respiratory protective equipment, because the volatile gaseous substances may irritate the respiratory tract and eyes, causing discomfort.
Furthermore, the use environment is also exquisite. The operation should be carried out in a fume hood to ensure that the volatile gas can be discharged in time to avoid accumulation in a limited space and reduce the risk of poisoning. The equipment used must be clean and dry to prevent impurities from interfering with its chemical reaction and affecting the experimental or production results.
When taking it, the dosage should be precisely controlled. Due to its high chemical activity, the dosage deviation or excessive or insufficient reaction will affect the follow-up process. After use, the remaining materials should not be discarded at will, and should be properly disposed of in accordance with relevant regulations to avoid polluting the environment.
In short, the use of 2% 2C6-dihydroxy-3% 2C5-dimethylpyridine requires rigorous operation from storage to use, and must not be slack to ensure safety and effectiveness.
