A solvent is a chemical substance that is capable of dissolving another substance (solute) without causing any chemical change. The word ‘solvent’ has been derived from the Latin word ‘solvo’, which means to untie or loosen. Solvents form an indispensable part of chemical reactions that take place. It is hard to imagine any mechanically important chemical reaction taking place without the use of solvents. For example, amidst the recent COVID-19 pandemic that struck the entire world, a huge demand for hand sanitizers was witnessed. That led to huge pressure on denatured ethanol suppliers as well as isopropyl alcohol suppliers. While alcohol forms the core component of these hand sanitizers, water is being used as a solvent in them.
Solute + Solvent = Solution
Generally, a solvent is a liquid. However, in some cases, it may also be a solid, gas, or supercritical fluid.
Classification of organic solvents
Based on the chemical structure, organic solvents are classified into the following types:
1. Halogenated solvents
Contain halogenic atoms such as chlorine (Cl), bromine (Br), iodine (I), fluorine (F).
Examples: Carbon tetrachloride, chloroform, ethylene dibromide, etc.
2. Hydrocarbon solvents
Made of only carbon and hydrogen atoms.
They are further classified as:
Aliphatic solvents: They have a straight chain structure. E.g. Hexane, gasoline, etc.
Aromatic solvents: They have a benzene ring structure. E.g. Toluene, benzene, etc.
3. Oxygenated solvents
Molecules contain oxygen.
These include alcohols, aldehydes, ketones, ethers, esters.
Applications of solvents
From an ethanol supplier in Gujarat to an isopropyl alcohol supplier in any other Indian city, all leading solvent suppliers are seeing tremendous demand from different industries. The reason behind this is that organic solvents are used in diverse industry verticals.
Pharmaceuticals and drugs
Wax and adhesives
Paintings and coatings
And many others.
Commonly used solvents:
1. Denatured Ethanol
This ethyl alcohol can be obtained from any leading ethanol supplier. It is adulterated with a toxic denaturant making it unfit for human consumption. It is a colourless clear liquid having a distinct odour.
Removal of paints and ink stains
Sterilization of medical instruments
2. Ethyl acetate
This solvent procured from top ethyl acetate suppliers in Gujarat is a colourless liquid having a fruity smell. Due to its use in different industries, it is always in great demand from ethyl acetate suppliers.
Inks and adhesives
Paints and varnishes
3. Isopropyl alcohol
This solvent can be obtained from isopropyl suppliers in Gujarat is a clean, colourless liquid, which is completely miscible in water. It is also known as rubbing alcohol.
This aromatic hydrocarbon offered by the top toluene suppliers has a benzene ring structure. It is a colourless fluid and insoluble in water.
Paints and thinners
Nail polish removers
