Regarding water solubility and non-water solubility
Thread Content
We are currently constructing a Class A storage tank area that contains liquids such as alcohols, ethers, toluene, and fats. According to Article 5.2.15, clause 2 of the \"Code for Fire Protection Design of Petrochemical Enterprises,\" a dike should be constructed between storage tanks for water-soluble and water-insoluble flammable liquids. I would like to ask how water-soluble and water-insoluble liquids are defined I searched on Baidu but couldn’t find it~~ Thanks in advance. This post was last edited by sunyun on 2009-2-20 11:22.]
It refers, of course, to the water solubility of the solvent – that is, whether it dissolves in water. For example, methanol and ethanol are water-soluble, while toluene is not.
In a narrow sense, it refers to the solubility of a substance in water; in a broader sense, it refers to its solubility in polar solvents. Molecules of water-soluble substances usually contain polar groups such as -OH, -SO3H, -NH2, -NHR, -COOH, etc., or relatively short carbon chains. For example, resins that can dissolve in water are called water-soluble resins; coatings that contain water-soluble resins as their main component are called water-soluble coatings; and phosphatic fertilizers that dissolve easily in water are called water-soluble phosphatic fertilizers. ——–This is what I found; for your reference!
According to the specifications in GBT 6324.1-2004 \"Test methods for organic chemical products – Part 1: Test for water miscibility of liquid organic chemical products\", water-soluble organic liquids are those liquid organic chemical products that can mix completely with water in any proportion while maintaining chemical stability. Water-insoluble liquids are also known as oils (the original English term refers to hydrocarbon liquids). The concept of water-insolubility is used in contrast to water solubility.
