    isopropyl alcohol or substitute ??

    Hi

    I am trying to remove a pad/ thermal compound from the base of my heatsink. I have been told that the best stuff to use is isopropyl alcohol. I have been all over town today and nowhere sells the stuff. Ive been to chemists theyre not allowed to so dont stock anymore. Halfords dont, computer shops for their own use but dont sell it. Where can i get it in the UK either shop or mail order.

    What else could i use that would be 100 % ok that someone has used before ???? would white spirit or turpetine substitute be ok ?? and is it ok to use these chemicals to get the thermal compound off the cpu ???


    thanks for replies

    Matt

    Ask them for rubbing alcohol.
    The main ingredient for rubbing alcohol is isopropyl alcohol.

    You can try a xylene based cleaner, (Goof Off and some carburetor cleaners) acetone or mineral spirits.

    You can check out the following, LINK.

    First time I got this stuff was years ago from my local chemist, but last year they too said that they werent allowed to sell it anymore.

    Searched high and low for the stuff, its great for all sorts of stuff.

    Anyway, Maplins.co.uk sell it in aerosol form: 10.
    Just go to their site and search for isopropyl.

    Meths works, but not too well, ANYTHING containing TRIKE (cant spell it but its pronounced trycloro ethane) cleans stuff really well, cant get trike on its own anymore but theres stuff called brake clean that contains it. Thats what I use, meths DOES work, I normally scrape off what I can with a credit card and clean it up with meths (trike STINKS)

    I'm surprised you can't buy isopropyl alcohol anymore. It's not particularly harmful and less flammable than meths. (Should have nicked some when I was still in the lab).

    Tape head cleaning fluid is basically isopropanol/isopropyl alcohol/propan-2-ol (3 different names for the same stuff).

    The best thing I found for removing the chewing-gum-type thermal paste from the bottom of a cooler was Turpentine substitute. (available from any DIY store). It's a non-polar solvent and I found it works better than more polar solvents such as isopropanol or acetone.

    Trichloroethane like most halogenated solvents are probably a bit difficult for the general public to obtain. (Too many potential health issues with halogenated solvents).

    Yes, nail polish remover is fine. The main ingredient in nail polish remover is acetone.

    I really don't believe you can't buy isopropyl alcohol man. Unless that's something over there in the UK. I can buy this stuff everywhere here...and I'm not even 18 yet, let alone 16. It is commonly known as rubbing alcohol. The proper terms for it are isopropylene and isopropanol. The other names are mentioned above. This stuff is nearly harmless, as it is actually used to clean cuts and abrasions as to make sure not to get an infection. It may also be used as mouthwash (when in a 1:1 ratio with water).

    The only reason they wouldn't sell isopropylene is because it can be used for explosives when in certain ratios with certain other chemicals. It is commonly used to make explosive pastes, or at least here with me it is However, by itself it is not a very strong reactant. In fact, it is a bit hard to ignite it straight out of the bottle, as the bottles are usually either in a 70% or 90% concentration. The remainder is of water. When absolutely purified, it does get more flammable. However, it leaves no residue and must be controlled to get a purified substance from it. It is most popular because it leaves no residue.

    Ok, enough info on isopropylene for you now, heh! I just know a lot about it because I've been using it for a few years now to clean various objects, cleanse cuts and abrasions, and many times in flammable/volatile mixtures that I concoct. Oh yeah, and I also did a report on it last year in Chemistry last year

    you can also use nail polish remover. Or, go to your local auto parts store and ask for an adhesive remover.

    Isopropylene is not the same Isopropyl alcohol.

    Isopropylene = alkene (CH3)2C=CH2 (cant do the subscripts in this text).

    Isopropanol/Isopropyl alcohol = alcohol (CH3)2CHOH

    Used to use 99+% IPA with our HPLC machine. Never seen a Isopropanol fire, although it is flammable.

    Here ends todays chemistry lesson.

    What about alcohol pads, like those used to swab your arm before a shot? As I recall, they are 70% isopropyl alcohol...

    Though I don't know whether these will work for you, or completely destroy your equipment (try at your own risk), what about some other solvents, like trichloracetic acid (TCA) or vinegar (usually 5% acetic acid). If it's alcohol you need, how about a few drops of 100 proof vodka (100 poof = 50% ethanol)?
