Polyvinyl acetate is soluble in a number of organic solvents. Solubility of polyvinyl acetate is directly related to the volatility of the solvent; the more volatile the solvent, the more soluble the polyvinyl acetate. Some of the most common solvents, ranked in order from the most volatile to the least, are listed below.1. diethyl ether (very volatile, water miscible) 2. acetone (best solvent that is commonly used) 3. benzene (very toxic) 4. ethylene dichloride (very toxic, non-water miscible) 5. methanol (toxic, cumulative poison) 6. methyl ethyl ketone (MEK) (toxic) 7. ethanol (denatured alcohols may be toxic) 8. toluene (slightly toxic) 9. xylene (slightly toxic) 10. amyl acetate (slightly water miscible) 11.ethyl acetate
What else can I help you with?
Is polyvinyl alcohol flammable?
No, polyvinyl alcohol is not flammable. It is a synthetic polymer that does not easily catch fire or burn.
How is polyvinyl alcohol made and what are the key steps involved in its production process?
Polyvinyl alcohol is made through the hydrolysis of polyvinyl acetate. The key steps in its production process include polymerization of vinyl acetate, hydrolysis of the polymer to form polyvinyl alcohol, purification, and drying.
Why is polyvinyl alcohol used to make hospital laundry bags?
Polyvinyl alcohol is used to make hospital laundry bags because it has good tensile strength, water solubility, and biodegradability. These properties make it suitable for holding soiled laundry in hospital settings where infection control and cleanliness are a priority. Additionally, polyvinyl alcohol can easily dissolve in water, making it convenient for washing the laundry without having to remove it from the bag.
Is polyvinyl alcohol ionic or covalent?
Polyvinyl alcohol is a covalent compound because it is made up of carbon, hydrogen, and oxygen atoms that are linked together through covalent bonds. It does not contain any ions.
Can you use polystyrene with polyvinyl alcohol polyvinyl acetate to make screen photo emulsion?
Polystyrene, polyvinyl alcohol, and polyvinyl acetate are not typically used in screen printing emulsions. Screen emulsions are usually made from light-sensitive compounds like diazo or photopolymer emulsions. These compounds provide the necessary properties for the emulsion to adhere to the screen and create a durable stencil for printing.
Why is heat needed to assist in dissolving polyvinyl alcohol?
Heat is needed to assist in dissolving polyvinyl alcohol because it increases the kinetic energy of the solvent molecules, allowing them to break the intermolecular forces holding the polymer chains together. This results in a faster and more thorough dissolution of the polyvinyl alcohol in the solvent.
