What are the main uses of ammonium (+) -3-bromocamphor-8-sulfonate?
(Plus) What are the main uses of the three-layer mill and the eight-gypsum bauxite?
"Tiangong Kaiwu" has a saying: "Where the three-layer mill is made, the upper one is suspended, and the lower one is placed on the stone. The middle one is connected with a wooden shaft. The upper one is stepped by a person, and the lower stone rotates with it. Anyone who has a solid grain and other things must be ground." The three-layer mill is mainly used to grind grains and other solid textures. By manually stepping on the suspended foundation, the stone grinding below is driven to rotate, so as to realize the function of grinding and play an important role in grain processing and other fields.
As for gypsum bauxite, "Gypsum is used to cement all kinds of ends, and it is combined with raw tung oil to imprison the seams of the boat and prevent water penetration, which is very useful. Bauxite is used to precipitate the pulp during papermaking to make the paper uniform and have the effect of preventing moths; in dyeing workshops, it can be used as a mordant to help the color adhere to the fabric." Gypsum and tung oil can be used to plug the seams of the boat after blending, prevent water leakage, and ensure the waterproof performance of the boat. Bauxite can precipitate the pulp during the papermaking process, making the paper uniform and dense, and can also prevent moths; in dyeing workshops, it can be used as a mordant to help the dye adhere better to the fabric and improve the dyeing effect.
What are the synthesis methods of (+) -3-bromocamphor-8-sulfonate ammonium salt?
To prepare the compound of chromium trichloride and octahydroxyquinoline, the methods are as follows:
First, the solution reaction method. Take an appropriate amount of chromium trichloride and dissolve it in water to make a solution. Take another octahydroxyquinoline and dissolve it in an appropriate organic solvent (such as ethanol). In the state of stirring, slowly drop the octahydroxyquinoline solution into the aqueous chromium trichloride solution. During the process, pay attention to the pH value of the solution. You can add dilute acid or dilute base dropwise to adjust it to make the reaction environment suitable. After dripping, continue to stir for two hours, and you can see that there is a precipitation. After filtering to obtain the precipitation, then wash it with an organic solvent many times to remove its impurities, and finally dry it at low temperature to obtain the product. This is a common method, easy to operate, mild conditions, and high product purity.
Second, solid-phase synthesis method. Chromium trichloride and octahydroxyquinoline are accurately weighed in a certain molar ratio and placed in a mortar. Use a pestle to fully grind to promote the solid-phase contact reaction between the two. When grinding, it is best to slowly apply force and continue for a period of time to make the reaction sufficient. After grinding, the obtained solid mixture is extracted with an appropriate solvent to separate the unreacted raw materials and impurities. After concentration, crystallization and other steps, the target compound can be obtained. This method requires no solvent or only a small amount of solvent. It is green and environmentally friendly, but the degree of reaction may be difficult to control, and the purity of the product may vary.
Third, hydrothermal synthesis method. Chromium trichloride, octahydroxyquinoline and an appropriate amount of water are placed in an autoclave. After sealing, the temperature is raised to a certain temperature and maintained for a period of time. In a hydrothermal environment, the molecular movement intensifies and the reactivity increases, which is conducive to the formation of complexes. After the reaction is completed, the reaction kettle is naturally cooled and the product is obtained by opening the kettle. The product obtained by this method has good crystallinity and uniform particle size. However, specific equipment is required, the cost is high, and the operation is dangerous.
What are the precautions for (+) -3-bromocamphor-8-sulfonate ammonium salt in storage and transportation?
Good, I want to say and （ + ） - 3 - milling machine - 8 - zinc sulfate crucible in storage and transportation, I should explain in detail.
The milling machine is a delicate device. When storing, the first thing is to choose a dry and well-ventilated place. If it is in a humid place, iron parts are prone to rust, which will damage their accuracy and lifespan. All parts of the milling machine should be properly placed, and the cutting tools must be removed to prevent damage to the cutting edge due to collision. And regularly apply protective oil to key parts, such as guide rails, screw rods, etc., to prevent corrosion.
As for the transportation milling machine, it must be firmly fixed on the transportation vehicle. Bind it with ropes or fixtures to prevent it from shaking or shifting during transportation, and avoid collisions. Packaging should also be comprehensive, wrapped in thick wood boards or foam materials to resist external impacts.
In addition, zinc sulfate crucibles should be stored away from high temperatures and open flames. Because they are chemical appliances, high temperatures may cause changes in the properties of internal substances, which will affect their subsequent use. And must be placed separately from other chemicals to prevent mutual reaction. Zinc sulfate crucibles are made of fragile materials and need to be padded with soft cushioning materials, such as sponges, bubble films, etc., during transportation. Handle with care and do not touch them.
When transporting, it is also necessary to pay attention to the clear signs, clearly indicating the words "fragile" and "handle with care", so that the transporter can treat it with caution. In this way, the milling machine and zinc sulfate crucible can be safely stored and transported.
