What are some chemicals?

Answer 1

Sulfuric acid (H2SO4)

Regardless of the year, sulfuric acid ranks among the world's first chemicals. The main use of sulfuric acid is to make fertilizers: ammonium sulfate and superphosphate.

However, sulfuric acid is also used in other products, including:

• Detergents

• Lead acid battery

• Other chemicals such as hydrochloric acid, dyes, explosives, pigments and drugs.

Sulfuric acid is also used as a reagent in the manufacturing or processing of certain products. Here are some examples of its functions

: • Remove pollutants from the oil refining process

. • Used to remove metal oxides before electroplating and metal plating

. • Remove water from certain chemical reactions

. • Used as a reagent in the production of nitroglycerin and nitroglycerin ethylene (C2H4)

Ethylene (C2H4)

Ethylene is one of the most important raw materials in the chemical industry, especially the plastics industry.

You will be surprised at how versatile this chemical is.The uses are as follows: Manufacturing ethylene glycol (antifreeze), styrene (used to make polystyrene for packaging and insulation) and polyethylene, from the most commonly used plastics; in fact, about half of the ethylene is used to make various types of polyethylene.

Production of ethanol for industrial use; according to the law, ethanol for human consumption must be made through fermentation. To produce polyester (like for the polyester leisure suits of the 1970s) to produce synthetic rubber

Propylene (C3H6)

Propylene is mainly used as and intermediate for the manufacture of other compounds, such as:

• When manufacturing polyethylene, synthetic fibers must be manufactured for indoor/outdoor carpets.

• Used in the production of propylene glycol used in automobile brake fluids, cleaners and paints

. • Produce polyurethane for rigid foam insulation

. • In the production of various types of ABS plastics used in telephones and auto trim part

Dichloromethane (C2H2Cl2)

The main use of ethylene chloride is to make polyvinyl chloride (PVC).The white plastic pipes that carry water underground and through the entire house are made of PVC, the backbone of the construction industry. Chlordane is also used to make polystyrene, another useful synthetic polymer. Chlordane is used in production• Some cleaning fluid • Floor • Shower curtain • Synthetic rubber

Phosphoric acid (H3PO4)

The following are some other uses of phosphoric acid:

Food additive: In the food industry, phosphoric acid is added as a food pH adjuster (in colas, for example), as a clarifying agent, and as a preservative.

Rust remover: Phosphoric acid acts as a rust converter, converting the ferric oxide (Fe2O3) to ferric phosphate (FePO4), which can then be easily scrubbed off. For this reason, phosphoric acid is usually sold in the form of a gel called sea Gelatin.
