MAGNESIUM CHLORATE Usage And Synthesis

Description

Magnesium chlorate is white crystalline solid.Molecular weight= 191.21; Boiling point= 120℃;Freezing/Melting point= 35℃. Soluble in water (reaction).

Chemical Properties

Magnesium chlorate is white crystalline solid.

Chemical Properties

White powder; bitter taste. Very hygroscopic. Soluble in water; slightly soluble in alcohol.

Uses

Magnesium Chlorate can used in Defoliant, desiccant.

Reactions

Magnesium chlorate is a powerful oxidizer. There is an explosive reaction with copper(I) sulfide, an incandescent reaction with antimony(III) sulfide, arsenic(III) sulfide, tin(II) sulfide, and tin(IV) sulfide. This salt is incompatible with Al, As, C, Cu, MnO2, organic matter, organic acids, phosphorus or sulfur. Mixtures with ammonium salts, with powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially unstable, even at room temperature. A combination of finely divided aluminum and magnesium chlorate can explode by heat, percussion, or friction. Magnesium chlorate is readily available commercially.

General Description

White deliquescent crystals or powder. Soluble in water and denser than water. Poses a dangerous fire risk when in contact with organic materials or heat. May be irritating to skin, eyes and mucous membranes. Used to make other chemicals.

Air & Water Reactions

Soluble in water.

Reactivity Profile

MAGNESIUM CHLORATE is a powerful oxidizer. Explosive reaction with copper(I) sulfide. Incandescent reaction with antimony(III) sulfide, arsenic(III) sulfide, tin(II) sulfide, tin(IV) sulfide. Incompatible with Al, As, C, Cu, MnO2, organic matter, organic acids, P and S. [Lewis, 3rd Ed . 786] . Mixtures with ammonium salts, with powdered metals, silicon, sulfur, or sulfides are readily ignited and potentially explosive [Bretherick 1979. p. 806]. A combination of finely divided aluminum and MAGNESIUM CHLORATE can explode by heat, percussion, or friction [Mellor 2:310. 1946-47].

Hazard

Dangerous fire risk in contact with organic materials, strong oxidizing agent.

Health Hazard

Inhalation, ingestion or contact (skin, eyes) with vapors or substance may cause severe injury, burns or death. Fire may produce irritating, corrosive and/or toxic gases. Runoff from fire control or dilution water may cause pollution.

Fire Hazard

These substances will accelerate burning when involved in a fire. Some may decompose explosively when heated or involved in a fire. May explode from heat or contamination. Some will react explosively with hydrocarbons (fuels). May ignite combustibles (wood, paper, oil, clothing, etc.). Containers may explode when heated. Runoff may create fire or explosion hazard.

Potential Exposure

Used as a drying agent and defoliant

First aid

If this chemical gets into the eyes, remove anycontact lenses at once and irrigate immediately for at least15 min, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts theskin, remove contaminated clothing and wash immediatelywith soap and water. Seek medical attention immediately. Ifthis chemical has been inhaled, remove from exposure,begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR ifheart action has stopped. Transfer promptly to a medicalfacility. When this chemical has been swallowed, get medical attention. Give large quantities of water and inducevomiting. Do not make an unconscious person vomit.Note to physician: Treat for methemoglobinemia.Spectrophotometry may be required for precise determination of levels of methemoglobin in urine.

storage

olor Code—Yellow: Reactive Hazard; Store in alocation separate from other materials, especially flam mables and combustibles. Prior to working with magnesiumchlorate you should be trained on its proper handling andstorage. Magnesium chlorate must be stored to avoid con tact with aluminum, arsenic, carbon, copper, phosphorus,sulfur, magnesium oxide, metal sulfides, fuels, and strongacids, since violent reactions occur. Store in tightly closed1638 Magnesium chloratecontainers in a cool, well-ventilated area away from flammable and combustible materials. See OSHA Standard1910.104 and NFPA 43A Code for the Storage of Liquidand Solid Oxidizers for detailed handling and storageregulations.
