What is the preparation method of 2-Naphthalamine-6-Sulphonic Acid?

The method of preparing 2-naphthylamine-6-sulfonic acid is not directly described in the ancient book "Tiangong Kaiwu", but there are many ways to learn from it in the chemical industry. According to the understanding of ancient chemical technology, it may be possible to deduce its preparation.
To obtain 2-naphthylamine-6-sulfonic acid, first use naphthalene as the starting material. For naphthalene, although there is no refining method in ancient times, it can be precipitated in coal tar and other substances. After taking naphthalene, the reaction of sulfonation should be carried out. The technique of sulfonation is to introduce sulfonic acid groups into the molecular structure of naphthalene. Concentrated sulfuric acid or fuming sulfuric acid can be selected as the sulfonating agent. In this process, the naphthalene and the sulfonating agent must be suitable for temperature and pressure. The temperature control is very important. If it is too high, it is easy to cause side effects such as polysulfonation, and if it is too low, the reaction will be slow. Generally speaking, the temperature control is in a moderate range, so that the sulfonic acid group just falls at a specific position in the naphthalene ring, so as to achieve the purpose of generating the precursor of 2-naphthalamine-6-sulfonic acid, that is, the naphthalene sulfonic acid isomer.
After obtaining the naphthalene sulfonic acid isomer, the step of amination is carried out. When aminating, a suitable amination In this step, it is also necessary to pay attention to the reaction conditions, such as temperature, pressure, reaction time and catalyst selection. The catalyst can promote the speed of the reaction and increase the rate of yield. After amination, an amino group can be introduced at the position next to the sulfonic acid group to obtain 2-naphthylamine-6-sulfonic acid. After
, there should be a process of separation and purification. The method of separation, or according to its physical and chemical properties, use crystallization, extraction, distillation, etc. Crystallization, using its solubility in different solvents and temperatures to precipitate the product; extraction is based on its distribution coefficient in different solvents to separate impurities; distillation is based on the difference between its boiling point and impurities. The purpose of purification is to remove by-products, unprocessed raw materials and other impurities from the reaction to obtain pure 2-naphthylamine-6-sulfonic acid. In this way, this compound can be prepared according to the principles of ancient chemical technology.

What is the market price range for 2-Naphthalamine-6-Sulphonic Acid?

2-Naphthylamine-6-sulfonic acid, the price range of this product in the market is difficult to determine. Its price often varies due to various reasons, such as the price of raw materials, the method of preparation, the supply and demand of the market, and even the state of the times.
In the past, if the raw materials were abundant and easy to obtain, the production method was simple and efficient, and the market demand was not extremely high, then the price might be relatively good. However, if the raw materials are scarce, the procurement is difficult, and the production process is complicated, requiring a lot of manpower and material resources, or the market is in short supply, the price will rise.
According to the "Tiangong Kaiwu" of the concept, the price of all things varies from time to place, and cannot be generalized. The same is true for this 2-naphthylamine-6-sulfonic acid, or at a certain time and place, the price is in a lower range, and it can be purchased with ordinary resources; and elsewhere, due to the above-mentioned changes, the price may be several times higher.
Basically speaking, if there are no special changes, the price may hover between [X1] and [X2] per unit of currency. However, this is only an approximate number, and the actual price should be carefully investigated according to the current market conditions. If the price of raw materials rises due to sudden changes in the market, or the cost drops due to new production methods, the price will change accordingly. Therefore, if you want to know the exact price range in the market, you must carefully observe the actual situation of the current market and the reasons for all the effects.

What are the storage conditions for 2-Naphthalamine-6-Sulphonic Acid?

2-Naphthylamine-6-sulfonic acid, this substance is a chemical substance, and its storage conditions are quite critical. It should be placed in a cool, dry and well-ventilated warehouse. Do not be close to fire and heat sources. The temperature of the warehouse should not exceed 30 ° C, and the relative humidity should be kept below 80%.
Because of its certain chemical activity, it should be stored separately from oxidants, acids, alkalis, etc., and should not be mixed. During storage, ensure that the container is well sealed to prevent leakage. If the storage environment humidity is too high, it is easy to cause moisture and deterioration; if the temperature is too high, it may cause chemical reactions and endanger safety.
Furthermore, the warehouse should be equipped with suitable materials to contain leaks in case of accidental leakage. When handling, be sure to pack and unload lightly to avoid damage to packaging and containers to ensure storage safety and prevent accidents.
