petrokemikaaleja

Petrokemikaaleja, or petrochemicals, are chemical products derived from petroleum or natural gas. These hydrocarbons undergo refining processes such as fractional distillation to separate them into various components. These components are then further processed through chemical reactions like cracking, reforming, and polymerization to create a vast array of intermediate and final products.

The primary petrochemicals include olefins like ethylene and propylene, and aromatics such as benzene, toluene, and xylene. Ethylene is a fundamental building block for plastics like polyethylene, used in packaging, films, and containers. Propylene is used to produce polypropylene, found in textiles, automotive parts, and packaging. Benzene is a precursor for styrene, used in polystyrene foam and synthetic rubber, and for phenol, used in resins and pharmaceuticals.

Petrochemicals are essential to modern life, forming the basis of countless materials and products. They are critical in the manufacturing of plastics, synthetic fibers, fertilizers, solvents, detergents, adhesives, paints, and pharmaceuticals. The petrochemical industry is a major global sector, underpinning many other industries and contributing significantly to the economy. However, the production and use of petrochemicals also raise environmental concerns related to greenhouse gas emissions, pollution, and the sustainability of fossil fuel resources. Efforts are ongoing to develop more sustainable alternatives and improve the environmental footprint of petrochemical processes.
