| | CALCIUM PERCHLORATE Usage And Synthesis |
| Description | The anhydrate is a white to yellow crystalline solid
with a density of 2.651 g/cm3. Contact with this salt
will irritate the eyes, skin and mucus membranes. If
ingested, it is toxic in sufficient quantities. When formed from an aqueous solution, the tetrahydrate
is obtained. Calcium perchlorate tetrahydrate has
the formula Ca(ClO4)2·4H2O and the CAS number
15627-86-8. Its molecular weight is 311.04 g/mol and its density is 2.651 g/cm3. Its solubility in water is 188 g/
100 ml at 20°C. | | Chemical Properties | white crystal(s); oxidizing agent [HAW93] | | Uses | Calcium perchlorate hydrate is used as a pharmaceutical intermediate. | | Preparation | Calcium perchlorate can be prepared by reacting
calcium carbonate with a solution of perchloric acid:
CaCO3＋ HClO4→Ca(ClO4)2＋ CO2
This salt can also be prepared by an electrochemical
method in water whereby calcium perchlorate is formed
from calcium chlorate in which a platinum anode and
a rotating stainless steel cathode is employed. | | General Description | White to yellow crystalline solid. Density 2.651 g / cm3. Contact may irritate skin, eyes, and mucous membranes. May be toxic by ingestion. | | Air & Water Reactions | Water soluble. | | Reactivity Profile | A strong oxidizing agent. Can react with reducing agents to generate heat and products that may be gaseous (causing pressurization in closed containers). The products may themselves be capable of further reactions (such as combustion in the air). Redox reactions can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Consequently explosive mixtures with reducing agents often persist unchanged for long periods. Such systems are typically mixtures of solids, but may involve any combination of physical states. Can react violently with active metals, cyanides, esters, and thiocyanates. May cause the acceleration of the burning of combustible materials. Prolonged exposure to heat of flames may result in an explosion. | | 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. |
