25813-71-2 - Introduction
scandium chloride hydrate is a compound composed of scandium ions, chloride ions and water molecules. Its chemical formula is ScCl3 · xH2O, where x represents the degree of hydration. The properties of scandium chloride hydrate are as follows:
1. Appearance: Usually colorless or white crystalline solid.
2. Melting point and boiling point: melting point is about 620 ° C, boiling point is about 1590 ° C.
3. Solubility: scandium chloride hydrate has high solubility in water and forms hydrate of scandium ion and chloride ion.
4. Chemical properties: scandium chloride hydrate is a strong Lewis acid, which can react with Lewis base. It is stable in air, but is susceptible to moisture crystallization in humid conditions.
scandium chloride hydrate is mainly used in the following aspects:
1. As a catalyst: scandium chloride hydrate can be used as a catalyst for organic synthesis reactions, such as asymmetric hydrogenation reactions.
2. Used as a material: scandium chloride hydrate can be used to prepare scandium metal or scandium alloy materials, which have high strength, high melting point and good corrosion resistance.
3. For research and analysis: scandium chloride hydrate can be used for titration and coordination chemistry experiments in analytical chemistry.
The method of preparing scandium chloride hydrate is usually to react scandium metal with hydrochloric acid to form scandium chloride, and then control the degree of hydration by controlling the temperature and humidity. The specific synthesis method also involves some detailed operations, which need to be carried out under the close control of the laboratory.
Note the following safety information when handling scandium chloride hydrate:
1. scandium chloride hydrate has a certain irritation, and should be rinsed with plenty of water immediately after contact with skin or eyes.
2. scandium chloride hydrate should not be in direct contact with metal to avoid hazards such as hydrogen generation.
3. During the operation of scandium chloride hydrate, good ventilation measures should be taken to avoid inhaling its dust.
4. scandium chloride hydrate should be stored in a dry, airtight container, away from organic matter and high temperature environment.
