Air & Water Reactions
Highly flammable. Pyrophoric, ignites spontaneously in air and forms magnesium oxide and water [Merck 11th ed. 1989]. Reacts with water to form caustic solution of magnesium hydroxide and hydrogen gas (H2) and heat sufficient to ignite the evolved hydrogen [Merck 11th ed. 1989].
Reactivity Profile
Hydrides, such as Magnesium hydride, are reducing agents and react rapidly and dangerously with oxygen and with other oxidizing agents, even weak ones. Thus, they are likely to ignite on contact with alcohols. Hydrides are incompatible with acids, alcohols, amines, and aldehydes.
Health Hazard
Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce corrosive solutions on contact with water. Fire will produce irritating, corrosive and/or toxic gases. Runoff from fire control may cause pollution.
Fire Hazard
Produce flammable gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard.
Potential Exposure
Used in hydrogen production and in
production of magnesium alcoholates.
Shipping
UN2010 Magnesium hydride, Hazard Class: 4.3;
Labels: 4.3-Dangerous when wet material.
Incompatibilities
A strong reducing agent. Pyrophoric:
the powder or dust may ignite spontaneously in air, or
in the presence of moisture. Contact with water or steam
forms magnesium hydroxide, flammable hydrogen gas,
and enough heat to ignite the hydrogen. Violent reaction
with oxidizers, alcohols, halogens, chlorinated solvents.
Incompatible with strong acids, acid chlorides, alcohols,
amines and aldehydes. Store under nitrogen. Decomposes
@ 280C in high vacuum
Check Digit Verification of cas no
The CAS Registry Mumber 7693-27-8 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 7,6,9 and 3 respectively; the second part has 2 digits, 2 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 7693-27:
(6*7)+(5*6)+(4*9)+(3*3)+(2*2)+(1*7)=128
128 % 10 = 8
So 7693-27-8 is a valid CAS Registry Number.
