Maratek Environmental is a leading manufacturer of solvent recycling and solent recovery equipment. In addition, Maratek can collect waste solvent solutions from businesses in the southern ontario region and process the solvent for either reuse or disposal.
Today we thought demystifying some of the facts about solvents would make an interesting post for our blog this week. Therefore we have done some research to bring you the facts behind solvents ... what they are and what they are used for.
A solvent (from the Latin solvō, "I loosen, untie, I solve") is a substance that dissolves a solute (a chemically different liquid, solid or gas), resulting in a solution.
A solvent is usually a liquid but can also be a solid or a gas. The maximum quantity of solute that can dissolve in a specific volume of solvent varies with temperature.
Common uses fororganic solvents are in dry cleaning (e.g., tetrachloroethylene), as paint thinners (e.g., toluene, turpentine), as nail polish removers and glue solvents (acetone, methyl acetate,ethyl acetate), in spot removers (e.g., hexane, petrol ether), in detergents (citrus terpenes), in perfumes (ethanol), nail polish and in chemical synthesis. The use of inorganicsolvents (other than water) is typically limited to research chemistry and some technological processes.
The global solvent market is expected to earn revenues of about US$33 billion in 2019. The dynamic economic development in emerging markets like China, India, Brazil, orRussia will especially continue to boost demand for solvents. Specialists expect the worldwide solvent consumption to increase at an average annual rate of 2.5% over the next years. Accordingly, the growth rate seen during the past eight years will be surpassed.
Physical properties of common solvents
Properties table of common solvents
The solvents are grouped into non-polar, polar aprotic, and polar protic solvents and ordered by increasing polarity. The polarity is given as the dielectric constant. The properties of solvents that exceed those of water are bolded.
