| 1407385 | 2015-08-26 06:49:00 | I'll try my local Pharmacy, we are on very good terms with them as both Mrs T and myself are regular customers. We've known them since they were a tiny start-up and they now have a massive shop in a busy mall. They did sell me a small bottle of pure ethanol when I needed to boost some simulator solutions for an evidential breath tester I was evaluating for the Supreme Court of a northern State in the US, so if they have Ethyl Acetate, I should be able to get it. Reading about it, it sounds like something that they might use for 'special potions', not everything can be just grabbed off the shelf. Just had a look on the wholesaler website for you - it's not available unfortunately. I've tried the synonyms, but to no avail. Renmoo |

| 1407386 | 2015-08-26 06:57:00 | Billy, there was a guy with knowledge of chemicals in the Grand Chancellor Hotel in Auckland yesterday. Sounds like he knew what he was doing! Maybe a little difficult getting in touch with him though. Ken (Sorry.... a bit out of left field that one but that is what the post was :) :) ) |

| 1407388 | 2015-08-26 11:07:00 | I always know the smell of toluene. Unsure why yours has no real odour. Actually I recall making Ethyl Acetate at Uni. Refluxing ethanol and acetic acid. Basically boil it, but need a catalyst (conc. acid maybe) and anti boil chips to speed up/control esterfication. But need a factional distiller to separate it during refluxing- so can't be easily done at home. Then need to purify/separate the solution (ester) a bit using a glass separation funnel. Acetone which is similar in formula may help - it's a bit more polar - therefore faster for extracting some compounds during solvent cleaning/extraction. But of course more harsh, and foul odour. if dealing with chemicals a bit, most chemists would consult the msds's (safety sheets) first, as I was trained to do so. So may want to find some online to review. |

| 1407389 | 2015-08-26 22:31:00 | I always know the smell of toluene . plenty of (very smelly) glue still using it as a solvent, although those glues may slowly be getting banned in various US states . Just how dangerous is toluene when used in household glues . Is it that bad in small quantities ? |

| 1407390 | 2015-08-27 00:59:00 | Coincidently, I have just shifted 4L of ethyl acetate into the solvent store. Are you near Palmerston North by any chance? | user (1404) | ||

I do have acetone (smell is quite nice, I have a feeling that one of our noses is out of calibration), in fact I have a broad range of solvents, all of which reside in my beer fridge in the man-shed, well away from sticky fingers. I have Toluene, Toluol, Methyl Ethyl Ketone [MEK], Xylol, Methanol, Acetone, lacquer thinners, a nail-polish remover that actually contains Ethyl Acetate (but also has castor oil in the mix) plus some other chemicals that won't help the cause; along with all the other usual culprits for gluing celluloid and removing tar from babies' bottoms etc. Sadly, I am also a long way North of Palmerston North. I shall visit my friendly Chemist and report back. Since both constituents are volatile evaporative solvents, I'm guessing that all that the thinners have to do is encourage full coverage and surface absorption of the actual adhesive +ferrite powder in the repair joint, then waft their way heavenwards, so if he can't help, I might get away with Acetone if I'm lucky.
