To make 5-amino-2-methylbenzimidazolone, you can follow the following ancient method.
First take an appropriate amount of o-toluenediamine and place it in a clean reactor. Slowly add formic acid, the ratio of the two needs to be precisely prepared, so that o-toluenediamine and formic acid interact in the appropriate amount. This reaction needs to be carried out at a specific temperature and pressure, slowly raise the temperature, maintain the temperature in the kettle within the appropriate range, and pay close attention to the change of pressure to not exceed the pressure limit.
At the beginning of the reaction, o-toluenediamine and formic acid come into contact with each other, and the molecules undergo wonderful chemical changes. As the temperature rises, the reaction becomes more and more intense, and the molecular structure is gradually rearranged and transformed. In this process, formic acid not only acts as a reactant, but also acts as a solvent to promote the smooth progress of the reaction.
When the reaction is to a certain extent, it can be seen that the physical state in the kettle has changed. After the reaction is completed, the product is carefully removed from the reactor for subsequent treatment. The product is washed with an appropriate solvent to remove any impurities mixed in it. After washing several times, the product gradually becomes pure.
Following the crystallization method, the product is precipitated from the solution. Control the crystallization conditions, such as the slow drop of temperature and the rate of stirring, etc., so that the product crystallizes well and the particles are uniform. The precipitated crystals are filtered and dried to obtain pure 5-amino-2-methylbenzimidazolone.
Although this process is described in ancient law, the beauty of chemistry exists. In actual operation, it is necessary to be careful and precisely control the reaction conditions in order to obtain satisfactory results, so that the purity and yield of the product meet expectations.

5-Amino-2-methylbenzimidazolone is used in storage and transportation, and attention should be paid to various things, which are related to the characteristics of materials, packaging, environment and many other aspects.
This substance has certain chemical activity and may have potential effects on the environment and human body. When storing, the first warehouse conditions. The warehouse should be dry and well ventilated to prevent moisture from causing material deterioration. Because it may be sensitive to humidity, humid environment or chemical reactions such as hydrolysis, it will damage the quality. And it should be protected from direct sunlight, light or promote photochemical reactions to change the chemical structure and properties.
Packaging is also key. It needs to be packed with well-sealed packaging materials, such as plastic barrels lined with plastic bags, or metal drums sealed packaging. The packaging should be solid to prevent collision and friction during transportation, causing package damage and material leakage. At the same time, the name of the substance, hazardous characteristics and other information should be clearly marked on the outside of the package for identification and handling.
When transporting, it is very important to choose a suitable means of transportation. Avoid mixing with oxidizing substances, acids, alkalis, etc., because of their active chemical properties, contact with the above substances or react violently, leading to safety accidents. During transportation, ensure that the temperature is stable and do not cause excessive temperature fluctuations. Some chemical substances may decompose and polymerize when the temperature changes drastically.
In addition, operators should be professionally trained to be familiar with the properties of the substance and emergency treatment methods. Storage and transportation sites should be equipped with corresponding emergency equipment and protective equipment, such as fire extinguishers, leakage emergency treatment tools, protective gloves, gas masks, etc., so that they can respond quickly to accidents and reduce hazards.
