Application:
Calcium Hydride (CAS: 7789-78-8) is an alkaline earth metal hydride, although it is not stable than lithium hydride, but stable than other alkali metal borohydride. Chemical formula is CaH2. Molecular weight is 42.10. When exposed to moist air hydrogen will release, and calcium hydroxide will leave. The proportion of is 1.9. The decomposition tempreture is about 600℃. Melting point is 816℃ (hydrogen). When meet water, carboxylic acids, lower alcohols, it can decompose to generate hydrogen. The decomposition When tempreture get 600℃, it begins to decompose. At room temperature, it can not react with dry oxygen, nitrogen, chlorine, but can react at high temperatures. This reaction can generate CaO, Ca3N2, CaCl2, respectively. At room temperature, it can react with water and the product is calcium hydroxide and hydrogen. It can be used as reducing agent and a condensing agent in organic synthesis, and desiccant in producing hydrogen material. it is regularly used in laboratories to produce small quantities of highly pure hydrogen for experiments. Used as in powder metallurgy. Reducing agents, gas dryer and chemical analysis reagents. Organic synthesis. Calcium hydride is used as an efficient drying agent for aprotic base-stable solvents like ethers and tertiary amines. It is a useful dehydrating agent in a synthesis of aldehyde enamines in high yield and purity. Category: Explosive substances. Explosive hazardous characteristics: When the reaction was heated with tetrahydrofuran, it can cause explosion; when mix with potassium chlorate, hypochlorite, bromate, perchlorate, it is heat sensitive, friction sensitive and explosive. Storage Characteristics: Treasury need ventilation low temperature drying; shockproof, moistureproof, against high temperature. Extinguishing agent: Foam, carbon dioxide, dry powder.Sufficient Capacity: Sufficient facilities and technicians
OEM Package: Custom package and label available
