Industrial synthetic acid plays an important role in the field of raw materials for chemical production, and its upstream and downstream related products are extensive. The main upstream and downstream associated products of industrial synthetic acids are described in detail below.

Upstream Associated Products

1. Sulfur: Sulfur is one of the main raw materials for industrial synthetic acid and is used to produce sulfuric acid.
2. Hydrocarbons: Hydrocarbon resources such as naphtha and natural gas can generate synthesis gas through oxidation reaction, which in turn can be used to produce synthetic ammonia and synthetic methanol.
3. Metal ores: used to produce metal oxides, and then react with acids to generate the corresponding salts.

downstream associated products

1. nitrogen fertilizer: industrial synthetic acid can be used to produce nitrogen fertilizer, such as ammonium sulfate, diammonium phosphate, etc.
2. Phosphate fertilizer: phosphoric acid is a kind of industrial synthetic acid, which can be used to produce phosphate fertilizer, such as superphosphate, compound fertilizer, etc.
3. Chemical raw materials: industrial synthetic acids can be used as chemical raw materials for the production of various chemicals, such as phenols, ketones, esters, etc.
4. Fine chemicals: Industrial synthetic acids can also be used to produce fine chemicals, such as pharmaceutical intermediates and food additives.

Specifically, the upstream and downstream related products of industrial synthetic acid include but are not limited to the following aspects:

upstream raw materials

1. Sulfur: Sulfur is the main raw material for the production of sulfuric acid, and sulfuric acid is an important product in industrial synthetic acid.
2. Natural gas: Natural gas can generate synthesis gas through conversion reaction, and then further synthesis of methanol, synthetic ammonia and other products.

downstream products

1. Nitrogen fertilizer: sulfuric acid in industrial synthetic acid can react with ammonia to produce ammonium sulfate, which is a commonly used nitrogen fertilizer.
2. Phosphate fertilizer: phosphoric acid in industrial synthetic acid can be used to produce phosphate fertilizer, such as potassium dihydrogen phosphate, diammonium phosphate, etc.
3. Chemicals: Industrial synthetic acids can be used as chemical raw materials for the production of various chemicals, such as formic acid, acetic acid, propionic acid, butyric acid, etc. These organic acids and their derivatives are widely used in various fields such as pharmaceuticals, pesticides, dyes, fragrances, plastics, and food additives.
4. Fine chemicals: Industrial synthetic acids can also be used to produce fine chemicals, such as various esters, ketones, phenols and other compounds, which are widely used in medicine, pesticides, spices and other fields.

In summary, the upstream and downstream related products of industrial synthetic acids are very extensive, involving fertilizers, chemicals, fine chemicals and other fields.
