What should be paid attention to when storing sodium 4-styrene sulfonate?
4-Benzyl-3-hydroxycoumarin cobalt, when storing, many matters should be paid attention to.
The chemical properties of this medicine are easy to decompose when exposed to light. Therefore, it should be placed in a dark place, or stored in a brown bottle to avoid direct sunlight, so as to prevent its quality from being changed by light.
In addition, the temperature has a great impact. Overheating can easily cause changes in its molecular structure and attenuation of its medicinal power; too cold can also change its properties. Usually it is appropriate to place it in a cool place, and it is most appropriate if it can be controlled between 15 ° C and 25 ° C.
Furthermore, the humidity of the air cannot be ignored. If the humidity is too high, it is easy to cause deliquescence and damage its quality. When choosing a dry place to store, or a desiccant is placed in the reservoir to keep it dry.
And this thing or phase with other things, if it coexists improperly, or reacts. Therefore, when storing, it must be far away from the reactive substance and cannot be mixed.
It should also be noted that the storage place should be convenient to take and clearly marked for easy inspection. In this way, 4-benzyl-3-hydroxycoumarin cobalt can be kept in storage, with the same quality and effectiveness, so as to be ready for emergencies.
What is the production method of sodium 4-styrene sulfonate?
4 - The dew stone gall in the tail flower is the name of the ancient pill medicine. The method of making it is quite complicated in the ancient records. According to the ancient method, there are the following systems.
Take the stone gall first, the one with the stone gall, out of the dark valley of Puzhou Mountain, the color is blue and blue, the shape is like gall, the nature is cold, and there is great poison. When choosing the stone gall, you need to choose the one with pure texture and bright color. Soak the stone gall in water, remove its impurities, drain it and set aside.
Take the tail flower for the second time, the tail flower is iris, which is born in the waterside wetland, and the flowers are colorful. When picking flowers, you need to choose the blooming flowers before the morning dew to preserve the essence of the flowers. After picking, put it in a cool and ventilated place to dry and grind it into fine powder.
Then, using the copper kettle as a vessel, lay a layer of fine sand on the bottom of the kettle, about one inch thick. Sprinkle the dried tail flower powder evenly on the sand, and then place the washed stone gall on the flower powder. Cover the kettle with a lid and seal its gaps with mud, so that it is tight and does not deflate.
Set the copper kettle on the charcoal fire and simmer slowly. Control of the heat is particularly critical. At the beginning, the fire should be mild, so that the things in the kettle are gradually warmed, and then the fire should increase slightly, so as to maintain the kettle slightly boiling. This calcination continues for seventy-seven forty-nine days, during which there should be no slack, and it needs to be taken care of day and night to prevent uneven heat.
When the time comes, remove the fire and wait for the kettle to cool naturally. Carefully unsealed, the contents of it are the eagle tail flower dew stone gall. This medicinal pill is turquoise and has a strange luster, and there is a faint floral fragrance mixed with the medicinal smell of the stone gall.
However, it needs to be made clear that such ancient medicinal pills contain many toxic substances. Although they have been said to have their medicinal uses in ancient times, modern medicine has proved that their safety is questionable, so they must not be made and taken according to ancient methods at will, so as not to endanger life.
