Methanol is suitable for precipitating polystyrene because it is a good non-solvent for polystyrene. When added to a polystyrene solution, methanol reduces the solubility of polystyrene, causing the polymer to precipitate out of the solution. This allows for the isolation of the polystyrene from the solvent.

What is the reaction of polystyrene and acetone?
When polystyrene (a plastic) is in contact with acetone, it can dissolve or soften the polystyrene. This is because acetone is a solvent that can break the bonds within the polystyrene polymer, causing it to swell or dissolve.
What does CH30H stand for?
CH3OH stands for methanol, which is a type of alcohol commonly used as a solvent, fuel, and antifreeze.
What is the role of methanol in the extraction of chlorophyll?
Methanol is commonly used as a solvent in the extraction of chlorophyll because it is highly polar and can effectively dissolve chlorophyll from plant material. Additionally, methanol helps to break down cell walls and release chlorophyll into the solvent, making it easier to extract. After extraction, methanol can be evaporated to leave the chlorophyll behind.
What is solvent in denatured alcohol?
Denatured alcohol typically uses methanol or other additives as the solvent. These solvents help dissolve the denaturing agents, such as acetone or gasoline, into the alcohol.
Which chemical dissolves thermocol?
Polystyrene, the main component of thermocol, can be dissolved by a solvent called limonene. Limonene is a natural solvent derived from citrus fruits and is effective in breaking down and dissolving polystyrene foam.
Is methanol a good solvent to use in paper chromatography?
Methanol is a commonly used solvent in paper chromatography because of its polarity and ability to dissolve a wide range of compounds. It is especially good for separating polar compounds. However, caution should be taken as methanol is also toxic and flammable.
What type of adhesive is recommended for bonding expanded polystyrene?
A solvent-based adhesive is recommended for bonding expanded polystyrene.
What glue destroys things?
Some adhesives act as solvents. For example, toluene is a solvent for polystyrene; it can be used to cause polystyrene parts to "melt" together, forming a permanent bond when the solvent evaporates. Xylene is a similar solvent/adhesive.
What is the best glue for polystyrene?
The best glue for polystyrene is a solvent-based adhesive specifically designed for bonding plastic materials.
What is the best adhesive for polystyrene materials?
The best adhesive for polystyrene materials is a solvent-based adhesive specifically designed for bonding polystyrene. These adhesives create a strong and durable bond between polystyrene surfaces.
What type of adhesive is best for bonding polystyrene materials together?
The best adhesive for bonding polystyrene materials together is a solvent-based adhesive specifically designed for polystyrene.
What type of glue is best for bonding polystyrene plastic?
The best type of glue for bonding polystyrene plastic is a solvent-based adhesive specifically designed for use with polystyrene.
Would methanol be a better or poorer solvent for extraction of cholesterol from egg yolk compared to 2-propanol?
The solubility of cholesterol in methanol is 0.014. 2-propanol would be a better solvent than methanol for the extraction of cholesterol from egg yolk.
What is a good solvent to extract Rhodamine B out of a highliter?
methanol
What type of glue is best for adhering polystyrene foam together?
The best type of glue for adhering polystyrene foam together is a solvent-based adhesive specifically designed for polystyrene.
