Acetone's Power: Dissolving Plastic Completely

Acetone is a commonly used, relatively inexpensive solvent. It can be used to dissolve certain plastics, although it depends on the chemical composition of the plastic in question. When acetone dissolves plastic, the acetone surrounds the plastic molecules, breaking down the structure of the plastic. The plastic molecules can then move about, solvated by the liquid acetone solvent. When the acetone evaporates, the plastic molecules are attracted to each other again and will assume the shape of the container and become hard once more.

Acetone can only dissolve certain plastics

Acetone surrounds the plastic molecules, which is the process called dissolving. The plastic molecules can move about solvated by the liquid acetone solvent. When the acetone evaporates, the plastic molecules are once again attracted to each other and will assume the shape of the container and become hard.

The rule of thumb is "like dissolves like". For instance, water, HOH is an excellent solvent for wood alcohol or methanol, CH₃OH. The feature that especially guarantees solubility is the –OH or hydroxyl group.

Acetone 100% works for dissolving PLA, but it doesn't fully dissolve it, it just softens it and makes it more pliable.

The plastic is unchanged except in shape

Acetone is a commonly used, relatively inexpensive solvent. A solvent is a medium not intended to react with a chemical, but to dissolve it so that the dissolved chemical can be put to some practical use.

It is important to note that solvents can carry plastic into your skin and plasticize (kill/embalm) your skin tissue, so it is recommended to wear gloves or use tweezers when handling plastic parts that have been soaked in acetone.

Acetone, also called dimethylketone or propanone, is a commonly used, relatively inexpensive solvent. A solvent is a medium not intended to react with a chemical, but to dissolve it so that the dissolved chemical, or solute, can be put to some practical use. The rule of thumb is that "like dissolves like". For example, water is an excellent solvent for wood alcohol or methanol.

Acetone does not chemically react with plastic. The plastic is unchanged except in shape, and if you evaporate the acetone, you will have a lump of plastic again, just like you would have salt again after evaporating water. The plastic molecules (polymers) are held together in a rigid solid form by intermolecular forces, attractive forces between molecules.

The plastic molecules are held together in a rigid solid form by intermolecular forces

Acetone is a hydrocarbon solvent that can be used to dissolve certain plastics. It is important to note that not all plastics can be dissolved by acetone, as it depends on the chemical composition of the plastic in question. When acetone comes into contact with a plastic it can dissolve, it surrounds the plastic molecules, breaking down their structure. The plastic molecules are then held together in a rigid solid form by intermolecular forces, which are attractive forces between molecules.

The process of dissolving plastic with acetone involves the acetone surrounding the plastic molecules, allowing them to move about as they are solvated by the liquid acetone solvent. This movement disrupts the intermolecular forces holding the plastic molecules together, causing the plastic to lose its rigid structure. Once the acetone evaporates, the plastic molecules are once again attracted to each other and will assume a new shape, becoming hard once more.

The solubility of a plastic in acetone can be predicted using Hansen solubility parameters, which calculate the relative energy difference between two molecules in 3D space based on their dispersion forces, intermolecular forces, and hydrogen bonding. This allows for a more advanced understanding of how acetone interacts with and dissolves certain plastics.

While acetone is effective at dissolving some plastics, it is important to note that it does not fully dissolve all plastics. In some cases, acetone may only soften the plastic, making it more pliable. This can be useful for cleaning or smoothing applications, but it is important to wear gloves or use tweezers when handling parts treated with acetone to avoid skin contact with the solvent.

It is important to note that while acetone can be effective for dissolving some plastics, it is not the only solvent capable of doing so. Other solvents, such as ethyl acetate, can also dissolve or soften certain plastics.
