Sourcing Ethyl Acetate?


Hello, I am looking for advice on sourcing Ethyl Acetate.

It seems Lowe's/HomeDepot no longer stock 1gal cans of "M.E.K substitute"(Ethyl Acetate)
And local hardware stores, if any only have a quart or two left from "M.E.K substitute" from before it was discontinued.

Also the Non-Acetone nail polish removers now often do not contain Ethyl Acetate like before, and if I manage to find a MSDS for a brand that contains Ethyl Acetate(60℅+) the retailer requires a Nail Salon registration or cosmetic student I.D to purchase.

Does anyone have any suggestions? The prices per liter via ebay/Amazon and etc are ridiculous for something that use to be available by the gallon at Lowe's/HomdDepot

I always find bans/restrictions concerning common solvents like this ridiculous. I just wanna sneer those lawmakers and these idiotic laws:P

PS me not american, can't help sry

Ethyl acetate isn't banned or restricted. They change the formulations of OTC products from time to time as safety standards change.

Where are you located? Sometimes there are good sources, but they are highly localized. There is at least one place in NC that I think still sells it, but might not help in other states. Someone near OK was talking about a place there that sells damaged freight that might have had some.

Since when is Ethyl acetate on the watched list? Did I miss something? I'll do a check at my local stor tomorow and see whats available. Ever since I started my Undergrad, I feel like I fell off the face of the earth , here.

It's not. A brand of M.E.K. substitute changed their formula. That's all.

Yes, I am aware of SierraChemicals on eBay and they're reputable quality but $40 for 1L is atrocious when it was available 3.7L for ~$20.

What you're getting from the hardware store is the same thing you're getting from a chem supplier?

Absolutely not, but tech grade vs lab grade is not a difference to justify a ~770% mark-up in price.

Just a public service announcement: You really should use the "Location" field in your profile. If you're in the US, put your state, at least. In other countries, put your province, region, or country. Whichever is responsible for your local laws. Otherwise, if you show up and ask where to buy something OTC, we have no idea what stores you have access to or what the local laws/restrictions are. I don't know why some people seem to think that posting their state or country is doxxing themselves. You have an entire state/country's worth of other people to hide among.

Incidentally, when you buy highly-flammable solvents online, most of the price you're paying is for hazmat shipping. You can also improve tech-grade solvents by a grade or two just by distilling from silica gel or something similar.




The first step in the process of learning something is admitting that you don't know it already.

I'm givin' the spam shields max power at full warp, but they just dinna have the power! We're gonna have to evacuate to new forum software!

Go to a beauty supply store and get the non-acetone nail polish remover. It should contain coloring, ethyl acetate, and a little bit of methanol. Distill the ethyl acetate. Then to a water wash to remove the methano, then do a brine wash to remove any traces of water. If you need it really dry, dry it with anhydrous potassium carbonate or molecular sieves 4A. A gallon costs about $30.

I found a cheap source of ethyl acetate in nail polish remover ... the ingredients are ethyl acetate, aqua, alcohol, ..., glycerol, triethanolamine, ...

So if I do a simple distillation at 70-80 C, I would expect a distillate mixture of ethyl acetate, alcohol and water right?
Would I expect the ethyl acetate to separate out into a separate layer even before the water/brine wash?
Strangely I dun see any separation in the orginal nail polish mixture even though there's significant water.

Just got a quart of Klean Strip MEK substitute at Home Depot for $10. Could not see it listed on their website; zero indication they carry it after extensive searching. Sitting right there with the other solvents, though. I wouldn't write it off until you've visited a few branches of Lowe's and Home Depot. The Klean Strip website is semi-helpful .

Beauty websites don't show what's available In the store. My local supplier says on the door "NOT OPEN TO THE PUBLIC". I got a gallon of non-acetone polish remover for $20, but it has MEK and ethyl acetate whose difference in BP are 2.54 °C. Not very worthwhile:P

The non-acetone nail polish remover at my local beauty supply store has only ethyl acetate, methanol, and coloring. Look at your label.

What I do is distill off the ethyl acetate, ethyl acetate and methanol will distill over. Then do 3 water washes. Then do a BRINE wash (this is saturated kosher salt (pure salt) water solution, it will absorb almost all the water out of the ethyl acetate. That's it, now you have pure ethyl acetate that you can dry further with molecular sieves 4A or anhydrous potassium carbonate or anhydrous epsom salt, then filter it off and store.

You don't see any separation in your original solution because ethyl acetate can dissolve up to 8% water.

I took a picture of the ingredients label, but I dunno how to attach pic ... but the ingredients are indeed ethyl acetate, (water)aqua, alcohol, glycerine, triethanolamine, tocopheryl acetate, blue 1, red 33

Water is second most abundant here ... would the glycerine serves as some kind of "emulsfier" to prevent the ethyl acetate and water from separating?

Most of your water will be removed during the brine wash, then you can dry it to 100% with the sieves or the epsom salt or K carbonate.

I wouldn't worry about the glycerine, it's boiling point is 290C, it will just remain in the boiling flask.

Be careful, ethanol and ethyl acetate form an azeotrope that boils at 71.85 deg C, 69.2% EtOAc by weight. I highly recommend do a few water washings before you actually distill so you don't have to perform multiple distillations; just distill all of the ethyl acetate at once.

What's the aim of doing water washings before distillation? I thought AcOEt, EtOH and water form a ternary azeotrope.
