The method of preparing γ-methylpyridine-N-oxide is not detailed in the ancient book "Tiangong Kaiwu", but it can be deduced from the general principles of chemical synthesis and similar ancient synthesis methods.
It is often obtained by oxidation with γ-methylpyridine as the starting material. In ancient chemical operations, oxidation depends mostly on oxidizing agents. Mild oxidizing agents, such as peroxides, can be used. In the past, peroxides were either extracted from natural substances or obtained by simple chemistry.
Place γ-methylpyridine and an appropriate amount of peroxide in a suitable reaction vessel according to a certain ratio. Ancient containers, or ceramic, porcelain, which has a certain degree of heat resistance and chemical corrosion resistance. The reaction system needs to be controlled at a suitable temperature. In ancient times, there was no accurate temperature control equipment, or according to experience, the temperature should be adjusted slowly by water bath or sand bath. During the reaction, it is necessary to stir frequently to make the reactants mix evenly and promote the reaction to go quickly. Ancient stirring, or use wooden or bamboo utensils.
After the reaction is completed, the product may be mixed in the impurities of the reaction system. Separation and purification are required. Ancient separation method, or according to the boiling point and solubility difference of the substance. If the method of distillation is used, according to the different boiling points of γ-methylpyridine-N-oxide and impurities, temperature control distillation is used to separate the product and impurities. Or by means of recrystallization, according to the difference in solubility in different solvents, the solvent is selected, the dissolved product and impurities are cooled and crystallized to obtain a relatively pure product. In this way, gamma-methylpyridine-N-oxide can be obtained.

Gamma-methylpyridine-N-oxide, when using this product, there are several important things to pay attention to.
First, safety is the key. Gamma-methylpyridine-N-oxide may be toxic and irritating, and it must be well protected when in contact. If it touches the skin or eyes directly, it may cause burns, allergies, etc. Therefore, when operating, you need to wear protective clothing, gloves and goggles to prevent it from contacting the body. In case of accidental contact, you should immediately rinse with a lot of water, and seek medical attention according to the severity of the injury.
Second, stability cannot be ignored. This substance is prone to chemical reactions under specific conditions or is unstable. In case of high temperature, open flame, strong oxidant, etc., or risk of combustion or explosion. When storing, it should be placed in a cool, dry and well-ventilated place, away from heat sources and fire sources, and do not mix with incompatible substances such as strong oxidants.
Third, the precise dosage needs to be controlled. According to the specific use and reaction requirements, accurately determine the dosage. Improper dosage, or poor reaction effect, or cause side reactions, not only affect the quality and yield of the product, but also may cause material waste and environmental pollution.
Fourth, the operating environment is also exquisite. The place of use should be well ventilated to prevent the accumulation of volatile gases, causing excessive concentration in the air, endangering the health of operators, and reducing the risk of explosion.
Finally, after use, properly dispose of the remaining materials and waste. Do not dump it at will, and treat it harmlessly in accordance with relevant regulations to protect the environment and avoid ecological hazards. In this way, gamma-methylpyridine-N-oxide can be used safely and effectively.
