13477-36-6 Usage
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.
Check Digit Verification of cas no
The CAS Registry Mumber 13477-36-6 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,4,7 and 7 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 13477-36:
(7*1)+(6*3)+(5*4)+(4*7)+(3*7)+(2*3)+(1*6)=106
106 % 10 = 6
So 13477-36-6 is a valid CAS Registry Number.
