What are Organic Solvents?
Organic solvents are used by everyone in most of the daily activities starting right from the disinfectant treatment to the removal of tough grease stains. The perfumes or cologne we use, laundry detergents which are used to keep clothes fresh and clean, all these products contain those ingredients called as Organic solvents.
Organic solvents are those chemicals compounds having carbon-based molecular structure. These are widely used in dissolving material in-order to create a solution, or even in extraction of one material from another material. In general, a solvent refers to the substance which is capable of dissolving any other substance. But, being carbon-based, all these solvents have the carbon atoms in the structure of compounds. Consider the below example of of an organic solvent benzene having six carbon atoms present in the organic solvent.Their molecular structure of an organic solvent always contains a carbon atom and some have hydrogen atoms. These solvents are mainly categorized based upon their molecular structures as natural and synthetic solvents.
Natural solvents– These are the solvents which are naturally produced by living organisms.
Synthetic Solvents– These are the solvents which are produced as a result of chemical reactions occurring in various organic compounds.
Types of Organic Solvents
Based upon the structure and the functional group, the different types of organic solvents are as explained below-
- Aliphatics solvents– These solvents belong to the class of alkenes. They are said to be nonpolar in nature. Some of the applications of such solvents includes oil extraction, paint, dye, pharmaceuticals, in polymerization and adhesives.
- Aromatic solvents– These like the aliphatic are said to be nonpolar solvents. They are utilized as industrial solvents for adhesives, paints, printing inks, extraction processes, decreasing, in insecticides, etc.
- Carbonyls solvents– These includes esters. They are said to exhibit polar properties and are used in the nail paint removers, electronic cleaners, circuit boards, decaffeination, in glues, and also in food flavouring substances.
Some of the other solvents includes alcohols which are used in various industrial and commercial applications.
Properties of Organic Solvents
Organic solvents do exhibit various physical and chemical properties as given below-
- Organic solvents are volatile in nature– Volatile solvents are those which have the ability to vapourise. Organic solvents possess these properties. Due to nature of volatility, organic solvents release smell when released into air.
- Organic solvents exhibit low boiling point- Organic solvents are said to have very low boiling points. Due to this low boiling point, they are highly volatile.
- Organic solvents are colorless liquids- These are clear liquids and have lower molecular weights.
Applications of Organic Solvents
Organic solvents finds its uses in different areas. These are used in coatings, polishes, as an paint thinner and remover( toluene), as cleaning agents, as a nail polish remover( acetone, ethyl acetate,methyl acetate), as an industrial as well as consumer degreasers, detergents, perfumes, spot removers and also in various chemical syntheses and processes.
