MOLECULAR SIEVE химические свойства, назначение, производство
Общее описание
Fine white powder. Many ordinary rocks (feldspars) are aluminosilicates. Aluminosilicates with more open three-dimensional structures than the feldspars are called zeolites. The openings in zeolites appear as polyhedral cavities connected by tunnels. Zeolites act as catalysts by absorbing small molecules in their interior cavities and holding them in proximity so that reaction among them occurs sooner.
Реакции воздуха и воды
May absorb moisture from the air. Insoluble in water.
Профиль реактивности
MOLECULAR SIEVE is generally unreactive. May serve as a catalyst to accelerate the rate of reaction between other substances.
Угроза здоровью
ACUTE/CHRONIC HAZARDS: Local irritant, low toxicity.
Профиль безопасности
An irritant to skin, eyes, and mucous membranes. When heated to decomposition it emits toxic fumes of Naz0. See also SILICATES and ALUMINUM COMPOUNDS.
