What are the precautions for the storage and transportation of phenylacetic acid?

For sulfonamide, many matters need to be paid attention to during storage and transportation.
First, storage, this is a crucial link. Sulfonamide acid is delicate and easily disturbed by the surrounding environment. First, it must be placed in a dry place to avoid moisture. If moisture soaks, sulfonamide acid is prone to moisture, which can cause qualitative changes or reduce its efficacy. Second, the temperature also needs to be carefully controlled. When stored in a cool place, it must not be close to high-temperature heat sources to prevent thermal decomposition and loss of original properties. And the storage place should be separated from other chemicals to avoid interaction and deterioration.
As for transportation, there are also many points. The packaging must be sturdy and tight to prevent bumps and collisions on the way, causing damage and leakage. The equipment to be transported must be clean and stain-free, and no impurities must be mixed into it to damage its purity. In addition, the transporter should be familiar with its nature and be able to deal with it properly in case of emergencies. If it is accidentally leaked, it should be disposed of immediately according to its characteristics and appropriate methods. It must not be panicked and cause the disaster to spread.
In addition, whether it is storage or transportation, the relevant signs must be indispensable. It is necessary to state its name, characteristics, hazards and protection methods, so that the contact person can see it at a glance and follow all actions. In this way, it is necessary to ensure that the sulfonic acid is safe and intact during storage and transportation, so as to ensure that it can be used where needed to show its effectiveness.

What are the preparation methods of phenylacetic acid?

Borax, known in ancient times as Pengsha, has been refined in ancient times.
In the past, in the Western Regions and other places, more borax was produced. Its production method, one is to extract raw ore from borax ore. Borax ore is mostly born in dry salt lake sediments and volcanic jet sublimation. The mined ore may be white or green in color, hard or brittle in quality.
Both, break the mined borax ore into small pieces. Soak it in water, put it in a large kettle, and boil it slowly. When the water boils, the borax gradually dissolves in the water, and the impurities settle at the bottom of the kettle. At this time, it is necessary to carefully skim off the floating foam to make the soup pure.
Three, when the soup is thick, like caramel, remove the kettle from the fire. Let it stand in a cool and ventilated place, and let it slowly cool and crystallize. When the crystallization is complete, the borax is ready, the color is white like snow, and the shape is like ice crystals. The purer is better.
There is also a method of combining borax with other things. If it is compatible with sulfur, etc., according to a certain proportion, it is calcined in a crucible over charcoal fire. During this period, the heat needs to be pinched precisely. If the fire is fierce, the borax will be easy to fly away, and if the fire is small, it will be refine. After this refining, the properties of borax may change, and it can be used in other ways.
Borax production method, although after years, but the ancient method, also contains the wisdom of the ancients, in today's chemical preparation, there is also a test.
