ビス過塩素酸ストロンチウム 化学特性,用途語,生産方法
化学的特性
white crystal(s); hygroscopic [STR93]
物理的性質
Strontium perchlorate has the formula, Sr(ClO4)2 and
a molecular weight of 286.52 g/mol. It is a white solid
with a melting point of 100°C. Its density is 2.073 g/
cm3 and it is lightly soluble in water (3.21 g/100 ml at
20°C). It can be prepared by reaction of strontium
carbonate with a solution of perchloric acid or ammonium
perchlorate:
SrCO3＋ 2HClO4→Sr(ClO4)2＋H2O＋ CO2
In an aqueous solution, the hexahydrate results.
Sr(ClO4)2·6H2O has the molecular weight of 394.63 g/
mol and a CAS number of 13450-97-0. A trihydrate,
Sr(ClO4)2·3H2O is also known, having the molecular
weight of 340.57 g/mol and a CAS number of 15650-
09-6.
一般的な説明
A colorless crystalline powder. Dangerous fire risk when in contact with organic materials. Used to make other chemicals.
空気と水の反応
Denser than water and soluble in water.
反応プロフィール
Oxidizing agents, such as STRONTIUM PERCHLORATE, can react with reducing agents to generate heat and products that may be gaseous (causing pressurization of closed containers). The products may themselves be capable of further reactions (such as combustion in the air). The chemical reduction of materials in this group can be rapid or even explosive, but often requires initiation (heat, spark, catalyst, addition of a solvent). Explosive mixtures of inorganic oxidizing agents with reducing agents often persist unchanged for long periods if initiation is prevented. Such systems are typically mixtures of solids, but may involve any combination of physical states. Some inorganic oxidizing agents are salts of metals that are soluble in water; dissolution dilutes but does not nullify the oxidizing power of such materials. Organic compounds, in general, have some reducing power and can in principle react with compounds in this class. Actual reactivity varies greatly with the identity of the organic compound. Inorganic oxidizing agents can react violently with active metals, cyanides, esters, and thiocyanates.
健康ハザード
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.
火災危険
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.
