illóanyag

Illóanyag, commonly known as solvent in English, refers to a substance capable of dissolving other materials without undergoing chemical change itself. Solvents are essential in various industries, including manufacturing, cleaning, and pharmaceuticals, due to their ability to dissolve solids, liquids, or gases to form homogeneous mixtures called solutions. They play a crucial role in processes such as painting, printing, and chemical synthesis, where precise dissolution and dispersion of substances are required.

Illóanyagok can be broadly categorized into organic and inorganic solvents. Organic solvents, such as acetone, ethanol, and toluene, are derived from petroleum or plant sources and are widely used in everyday applications like nail polish remover, paint thinners, and cleaning agents. Inorganic solvents, on the other hand, include water and liquid ammonia, which are often used in industrial and laboratory settings due to their non-flammable properties.

The choice of solvent depends on factors such as the solubility of the solute, environmental impact, cost, and safety. Some solvents, like chloroform and benzene, have been phased out or restricted due to their toxicity and environmental hazards. Modern research focuses on developing eco-friendly alternatives, such as biodegradable solvents or supercritical fluids, to minimize ecological damage.

In addition to their industrial uses, solvents are also found in household products, including dry-cleaning fluids, adhesives, and insecticides. Proper handling and disposal of solvents are critical to ensure safety and compliance with environmental regulations. Understanding the properties and applications of illóanyagok helps in selecting the appropriate solvent for specific tasks while mitigating potential risks.
