Do you think calcium hydride can be used as desiccant

Introduction: we know that calcium hydride has the function of adsorption, static dehumidification and odor removal Do you think calcium hydride can be used as desiccant? Let's take a look at it together with the small edition of Baibai safety net! We know that calcium hydride has the function of adsorption, static dehumidification and odor removal Do you think calcium hydride can be used as desiccant? Let's take a look at it together with the small edition of Baibai safety net! Calcium hydride is a common chemical reagent Its formula is CaH2 and molecular weight is 42.10 [1] Gray white crystal or block, easy to deliquesce, used as reducing agent, desiccant, chemical analysis reagent, etc.; it is also colorless rhombic crystal system crystal; industrial products are gray, orthorhombic crystal or powder Sensitive to moisture It does not react with dry air, nitrogen and chlorine at normal temperature, but it can react with the above gases at high temperature to generate calcium oxide, calcium carbide and calcium chloride respectively It can also react with ethanol to produce hydrogen and ethanol calcium The reduction of metal oxides is stronger than that of sodium hydride or lithium hydride Therefore, calcium chloride can be used as desiccant Precautions for the use of desiccant 1 The desiccant that has not been used up should also be sealed and stored rather than placed at will 2 The desiccant must be sealed and stored, isolated from the outside air, and the effect will not be greatly affected when it is used next time If the desiccant is not properly preserved and absorbs too much water from the outside air, it may be saturated without being put into the product Then, when such a product is put into the product, it can no longer play its moisture absorption effect 3 During transportation, handle with care to avoid internal and external package damage; keep the transportation and storage environment cool and dry The above is a small part of Baibai safety net, which provides you with an answer about whether you think calcium hydride can be used as a desiccant If you want to know about the types of desiccants and other small knowledge, please pay attention to the food safety knowledge of Baibai safety net, and hope the above content can help you Editor in charge: Wu Mengli
