Question

СРОЧНО!!!!!!!!! Промышленное производство серной кислоты.

Answer 1

Ответ:

Процесс производства серной кислоты при использовании серы можно разделить на три этапа. Первый из них заключается в производстве диоксида серы. Затем диоксид серы окисляют для получения триоксида серы. Последний этап заключается в превращении оксида серы (VI) в серную кислоту.

Answer 2

Industrial Production of Sulfuric Acid

Sulfuric acid is one of the most widely used chemicals in various industries, including the production of fertilizers, dyes, detergents, and pharmaceuticals. It is also used in the manufacturing of batteries, as well as in the petroleum and mining industries. The industrial production of sulfuric acid involves several steps and processes.

1. Sulfur Extraction: The first step in the production of sulfuric acid is the extraction of sulfur. Sulfur can be obtained from various sources, including natural gas, crude oil, and metal sulfide ores such as pyrite. The extracted sulfur is then purified to remove impurities.

2. Sulfur Burning: Once purified, the sulfur is burned in the presence of oxygen to produce sulfur dioxide (SO2). The reaction can be represented as follows:

S + O2 → SO2

3. Conversion to Sulfur Trioxide: The next step involves the conversion of sulfur dioxide to sulfur trioxide (SO3). This conversion is typically carried out using a catalyst, such as vanadium pentoxide (V2O5), at high temperatures. The reaction can be represented as follows:

2SO2 + O2 ⇌ 2SO3

4. Absorption and Oleum Formation: The sulfur trioxide is then absorbed in concentrated sulfuric acid (H2SO4) to form oleum, also known as fuming sulfuric acid. The reaction can be represented as follows:

SO3 + H2SO4 → H2S2O7

5. Dilution and Formation of Sulfuric Acid: Finally, the oleum is diluted with water to produce sulfuric acid (H2SO4). The dilution process is carefully controlled to prevent the release of excessive heat and the formation of hazardous fumes. The resulting sulfuric acid can be further purified and concentrated as required for specific applications.

It is important to note that the industrial production of sulfuric acid involves complex equipment and safety measures due to the corrosive nature of the acid and the potential hazards associated with the process.
