What are the common synthesis methods of 2-%-4-aminobenzoic acid?, the following imitation of "Tiangong" answers this question in classical Chinese.
The method of synthesizing 2-4-aminobenzoic acid by husband is many. First, the product starting with benzoic acid is first nitrified to obtain nitrobenzoic acid. This step requires careful nitrification, control of the reaction rate and resistance, in order to prevent the growth of side reactions. In addition, nitrobenzoic acid is added to the original to make the nitro group. The amino group is often synthesized with powder, acid, etc. In this step, 2-4-aminobenzoic acid can be obtained.
Second, toluene is used as the starting material. Shilling toluene is nitrified under the appropriate conditions to obtain nitrotoluene. The position of the nitro group needs to be precisely controlled, and it can be synthesized by catalyzing the synthesis of chemical and reverse components. And then, the oxidation of nitrotoluene makes the methyl group and carboxyl group to obtain nitrobenzoic acid. In addition, as in the previous method, the nitro group is made by the original method to synthesize 2-4-aminobenzoic acid.
Furthermore, there are also those who start with phthalic acid anhydride. The phthalic acid anhydride first reacts with ammonia to generate phthalamide. Then, with the appropriate method, the phthalamide is degraded, the amino group is introduced, and the carboxyl group is retained. A series of reversals are made, and 2-4-aminobenzoic acid can also be obtained. In this way, it is necessary to consider the reverse parts of each step in order to improve the efficiency and obtain high-quality products.
All this synthesis method requires the operator to be familiar with the principle of chemical chemistry, be proficient in operation skills, and carefully control the reverse parts in order to make the synthesis profitable and obtain the required 2-4-aminobenzoic acid.

2-% question-4-aminoacetylaniline needs to pay attention to many matters during storage and transportation. This is the key to material safety and quality.
When storing, choose the first environment. Find a cool, dry and well-ventilated place. If the environment is humid, 2-aminoacetylaniline is very susceptible to moisture, resulting in deterioration of quality, or even triggering chemical reactions that damage its original chemical properties. And if the temperature is too high, it may also promote adverse reactions such as decomposition, so it is essential to maintain a suitable temperature. Furthermore, the storage place must be away from fire and heat sources. Because of its certain flammability, there is a risk of fire in case of open flames and hot topics, endangering the safety of personnel and property. At the same time, it should be stored separately from oxidants, acids, alkalis, etc. Because these substances are in contact with them, it is easy to trigger chemical reactions and lead to dangerous situations.
During transportation, the packaging must be tight and stable. Select appropriate packaging materials to ensure that 2-aminoacetaniline does not leak during transportation bumps. Transportation vehicles also need to take protective measures to avoid direct sunlight and rain. During driving, drivers should always pay attention to road conditions, drive smoothly, and prevent violent actions such as sudden braking and sharp turns to avoid damage to the packaging. And the transportation process should strictly follow relevant regulations and standards, and be equipped with necessary emergency treatment equipment and protective equipment. In the event of an accident such as leakage, they can quickly and effectively respond to it and reduce hazards. Only in this way can we ensure the safety of 2-aminoacetaniline during storage and transportation, and maintain the normal operation of production and use.
