Making Naphthalene Crystals
I realized that time passes so fast, it was about a week since I made a new post. I feel like it has been for only 3 days. Anyways, let’s get started with the post.
I’ll try to make Naphthalene crystals. Naphthalene is a white crystalline solid with a characteristic odor. It’s melting point is about 80°C. If you leave it to expose air, it’ll change into a gas.
My Naphthalene:
I put about 7 balls of Naphthalene into a 600 ml beaker, and I put a flask with cold water on top of it.
The Naphthalene is vaporizing quickly. The vapors will get in contact with the cold water in the flask and turn back into a solid.
Crystals are also forming in the beaker, because it’s touching the cold air outside, just like what’s happening in the flask.
All of the Naphthalene has changed into liquid, it was boiling a little too fast so I stopped the heat.
The crystals are so fragile so I used a trash bag to make the crystals fall onto it.
Here are the crystals. They look like fern leaves and snowflakes! But I wish the crystals were chunks, not thin like this. I looked in the internet for pictures of Naphthalene crystals, and they’re just like mine. The reason that it’s yellow is because the light is just reflecting it.
Here’s the beaker:

Thank you so much! Really appreciated it.
It np
hahaha I’m sure! đŸ˜€
Thanks!
I thought you would. Be sure to take care Dan
Thank you for visiting!
Hehe, yes. Because when I make the crystals I have to open windows and turn on fans XD
I know that already. Thanks for warning me! đŸ™‚
Good idea! Well done.
nice. I remember doing this experiment
Ah I see. And I’m not surprised it kills moths – it smells strong enough! đŸ˜€
Do be careful with naphthalene. if you research it you will find its toxic.
I put them outside in my planters and it keeps the critters from digging into them.
XD XD XD
Looks like it…đŸ˜¬
They are moth balls!
This is actually pretty dangerous though…
Killing insects such as moths and silverfish, it has a lot of uses đŸ™‚
Ha I thought they were moth balls!
It turns from a solid to a gas, but in some cases, it’ll turn from a liquid to gas just like water. Mothballs are made from naphthalene, and it is used to kill insects such as moths and silverfish đŸ™‚
This is just so cool. I wish I could do experiments like this!đŸ˜…
Cool crystals! What is Naphthaline I used for?
What a fun experiment! I love the delicate fern-like crystals, which you have photographed so well.
I think moth balls are made from naphthalene? They have a very strong smell.
And I’m trying to remember my chemistry, but I thought naphthalene sublimed? – goes straight from a solid to a gas? Maybe it depends on the pressure and temperature.
