Ртуть сернокислая(II) химические свойства, назначение, производство
Химические свойства
White crystals or powder. Mercuric sulphate decomposes on contact with water into yellow insoluble basic sulphate and sulphuric acid. The products of decomposition of mercuric sulphate include oxides of sulphur and oxides of mercury. Mercuric sulphate is incompatible with acetylene, ammonia, and strong acids and corrosive to iron, magnesium, aluminium, zinc, lead, and copper.
Использование
Mercury(II) sulfate is used for gold and silver extraction, and to make other mercury compounds. Used as catalyst in the conversion of acetylene to acetaldehyde and used as a electrolyte in primary battery. It is commonly used as a catalyst in oxymercuration-demercuration, a type of electrophilic addition reaction.
Общее описание
Odorless white granules or crystalline powder. Denser than water. MERCURY(II) SULFATE is toxic by inhalation and by ingestion. MERCURY(II) SULFATE is used in medicine, for gold and silver extraction, and to make other mercury compounds.
Реакции воздуха и воды
Decomposed by water to yellow mercuric subsulfate and sulfuric acid, which is corrosive.
Профиль реактивности
The absorption of gaseous hydrogen chloride on MERCURY(II) SULFATE becomes violent at 125° C [Mellor 2, Supp. 1:462. 1956].
Опасность
Highly toxic by ingestion, inhalation, and
skin absorption.
Угроза здоровью
INHALATION: Acute poisoning: Tightness in chest, breathing difficulty, coughing, and pain. EYES: Ulceration of conjunctiva and cornea. SKIN: Irritation; may cause sensitization dermatitis. INGESTION: Necrosis, pain, vomiting, severe purging. Patient may die within a few hours from peripheral vascular collapse.
Пожароопасность
Special Hazards of Combustion Products: None
Профиль безопасности
Poison by ingestion and
intraperitoneal routes. Moderately toxic by
skin contact. When heated to decomposition
it emits very toxic fumes of Hg and SOx. See
also MERCURY COMPOUNDS.
Возможный контакт
Mercuric sulfate is used in making
other chemicals; as a battery electrolyte and in extracting
gold and silver from rock
Перевозки
UN1645 Mercury sulfates, Hazard Class: 6.1;
Labels: 6.1-Poisonous materials
Несовместимости
Contact with water produces sulfuric
acide and insoluble basic mercuric subsulfate. Reacts with
acids producing mercury vapors. Violent reaction with gaseous hydrogen chloride above 121C. Decomposes in heat
or on exposure to light, producing toxic fumes of mercury
and sulfur oxides. Attacks magnesium, aluminum, zinc,
iron, lead, copper.
