Naphthalene storage


I'm having trouble finding a cheap naphthalene here in europe.
What prompts me to buy a little more and put it in storage.

I know this stuff is going to evaporate over time, and since I'll have to store it in my working area I dont want it to stink around. Yes, I know, they used these mothballs in the old days, anyway, I dont like it.

Will it stink/permeate through HDPE over time?
Do I need glass vessels?

The naphthalene I bought as mothballs from a hardware store came in porous plastic bag inside a cardboard box, went unopened for several weeks, and still weighed in very close to what was listed on the box. I don't think you need anything more than a glass jar.



Reflux condenser?? I barely know her!

Glass is fine. You will definitely smell it through HDPE, at least eventually, but you won't lose a discernible amount of it through diffusion.

I have jars of naphthalene that date from the 1940's and they are just fine. The hydrocarbon tends to migrate around inside the jars by sublimation but I can see no evidence that significant loss has occurred. The jars are glass with lacquered metal or bakelite lids but as UC235 said, I would avoid plastic jars.

I saw Naphthalene, for sale here in the USA, a year or two ago. Four Bucks a pound, at Walmart. God that stuff stinks. I was keeping some in a clothes closet (for Moth Prevention) until the odor became oppressive. The stench did not leave my woolens easily. Eventually, I put it in a sealed Mason Jar. Just the right thing.

Right price too. Quart Mason Jars, cost about $12 a dozen here. Hmmm. I wonder if I can buy the such jars, in "Brown Glass"?

Seems to me, I've had items like Camphor, "burn" right through their plastic bags. Might take a few months, or years, but the ability of plastics to resist chemicals, is sometimes only transitory.
