Methyl iodide facts for kids
Methyl iodide is a chemical compound that's also known as iodomethane. It's made from two parts: a methyl group and an iodide ion. Think of it like a tiny building block in chemistry. Its chemical formula is CH3I.

What is Methyl Iodide Like?
Methyl iodide is a liquid that evaporates easily, meaning it can turn into a gas quickly. When this liquid is exposed to light, it can change color and turn purple. This happens because of a tiny bit of iodine forming. You can stop this color change by storing it with copper.
If you heat methyl iodide, it breaks down into other substances. These include carbon dioxide (the gas we breathe out), carbon monoxide (another gas), and hydrogen iodide.
How is Methyl Iodide Made?
Scientists can make methyl iodide in a few ways. One common method involves mixing three things together: iodine, red phosphorus, and methanol. During this reaction, another chemical called Phosphorus(III) iodide is temporarily formed.
Another way to create methyl iodide is by reacting methanol with potassium iodide. For this reaction to work well, a little bit of sulfuric acid is also added.
What is Methyl Iodide Used For?
Methyl iodide is useful in organic chemistry, which is the study of carbon-containing compounds. It's often used to add a "methyl group" to other organic compounds. This is like adding a specific Lego block to a larger structure to change it.
It can also be used as a pesticide. Pesticides are chemicals that help control pests like insects or weeds that might harm crops. Methyl iodide has been used to prepare soil before planting to get rid of harmful organisms.
Additionally, it's used to create other chemicals, such as dimethylmercury.
Is Methyl Iodide Safe?
It's important to be careful around methyl iodide. If someone breathes in its vapors, it can cause them to feel nausea (like they might throw up) and dizziness. If the liquid touches skin, it can cause burns. Because of these risks, it should always be handled with great care and by trained professionals.
