How to get sulfur?
In general, the question of how to getsulfur is quite interesting and entertaining, if only because sulfur is a part of not only mountain and natural rocks and is necessary for human life, but also is a part of the human body itself. Sulfur is a typical non-metal and a combustible chemical element. Since ancient times, people have used sulfur in everyday life and found ways to extract it. At this point in time, many methods of obtaining sulfur have been discovered.
The most common way of obtaining sulfuris a method proposed as far back as 1890 by G. Farsh. He suggested melting the sulfur underground and using the wells to pump it to the surface. The idea was that sulfur is a low-melting chemical element whose melting point is 113 0C, which greatly facilitates the sublimation process. On the basis of the proposed idea, different methods of obtaining sulfur from sulfuric ores and mountain deposits arose:
- steam-water,
- filtration,
- thermal,
- centrifugal,
- extracurricular.
All these methods and methods are widely used inmining industry. Also popular is the method of extracting chemically pure fine sulfur from natural gas, which is an ideal raw material in the chemical and rubber industries. Since sulfur in large quantities is contained in the gaseous form in natural gas, then when gas is extracted it settles on the walls of the pipes, quickly disabling them. Therefore, there was a way to catch it right after gas extraction.
How to get sulfur oxide
Sulfur Oxide (VI) is a volatile colorless liquid with a suffocating, pungent odor. The simplest and most common methods of producing sulfur oxide are:
- In the presence of the catalyst, the sulfur oxide (IV) is oxidized by heating with air, thereby obtaining sulfur oxide (VI).
- Thermal decomposition of sulfates.
- Sulfur (IV) oxide is oxidized by ozone to produce sulfur oxide (VI).
- Nitric oxide is used in the oxidation of sulfur (IV) oxide, thereby obtaining sulfur oxide (VI).
How to Obtain Sulfur Oxide 4
Sulfur (IV) oxide, or sulfur dioxide gas - colorlessgas with a characteristic suffocating odor. Under laboratory conditions, sulfur (IV) oxide is obtained by reacting sodium hydrosulfite with sulfuric acid or heating copper with concentrated sulfuric acid. Also in nature and in laboratory conditions, a method for the production of sulfur oxide (IV) by the action of strong acids on sulphites and hydrosulfites is common. As a result of this reaction, sulfuric acid is formed, which immediately decomposes into water and sulfur oxide (IV). An industrial method for the production of sulfur oxide (IV) is the burning of sulfur or the burning of sulfides-pyrite.
How to get sulfur from hydrogen sulphide
The method for obtaining sulfur from hydrogen sulphide is carried outin the laboratory. It should be noted immediately that a similar method of obtaining sulfur should be carried out with all safety measures, since hydrogen sulphide is an active and poisonous substance. The essence of the method is the interaction (reaction) of hydrogen sulfide with sulfuric acid, resulting in water, sulfur dioxide, gas and finely dispersed sulfur, which will remain at the bottom of the tube at the end of the reaction as a precipitate. The resulting precipitate is filtered, washed and allowed to dry. This will be finely dispersed sulfur.
