<p>Acetone is banned in my country, and I cannot get it.</p>

<p>What substitute could I use?</p>

Is it for dissolving ABS? A <a href="https://www.google.com/search?q=accetone%20substitute" rel="nofollow noreferrer">quick google search</a> should show you what you want.</p>\n\n<p>The thread, <a href="https://www.researchgate.net/post/Could_you_recommend_me_a_suitable_alternative_to_acetone_as_solvent" rel="nofollow noreferrer">Could you recommend me a suitable alternative to acetone as solvent?</a>, has a good many points that are worth considering:</p>\n\n<p>For example, you may need to consider the <em>Polarity Index</em></p>\n\n<blockquote>\n  <p><a href="http://macro.lsu.edu/howto/solvents/Polarity%20index.htm" rel="nofollow noreferrer">Burdick &amp; Jackson solvents</a> are arranged in order of increasing\n  polarity index, a relative measure of the degree of interaction of the\n  solvent with various polar test solutes.</p>\n</blockquote>\n\n<p>If you are using it to dissolve a polymer other than ABS, then the family/class of polymer may need to be considered:</p>\n\n<blockquote>\n  <p>Apart from your desired solvent qualities (non-flammability and low boiling point), the choice will be totally dependent on the family/ class which the polymer\xa0 belongs. Based on the principal that \'like dissolves like, the attached document will provide you with good ideas on which solvent to use when a particular repeating unit of the polymer is involved. </p>\n</blockquote>\n\n<p>Butanone is a possibility:</p>\n\n<blockquote>\n  <p>One alternative is butanone (button-2-one) - this is similar to acetone, but has a much higher boiling point. It is often used for alkylations etc. It has a boiling point of 79-80°C compared to 56°C of acetone. </p>\n</blockquote>\n\n<p>or NMP:</p>\n\n<blockquote>\n  <p>N-methyl-2-pyrrolidone (NMP) can be used. It is a polar aprotic solvent and dissolves many polymers. It has high boiling point ( >200 degree centigrade)\xa0 It is soluble in water and easy to dispose which is a great advantage during work up of reactions. </p>\n</blockquote>\n\n<p>However, some other alternative chemicals are listed here (from <a href="https://www.mindat.org/forum.php?read,6,266290,271485" rel="nofollow noreferrer">Any good alternative to Acetone</a>?:</p>\n\n<ul>\n<li>Butyl alcohol</li>\n<li>methyl isobutyl keytone (MIBK)</li>\n<li>denatured alcohol</li>\n<li>MEK (methyl,ethyl,ketone), i.e. Kleen-Strip MEK Alternative</li>\n<li>Ethyl Acetate</li>\n</ul>\n\n<p>Some branded items, from <a href="https://www.hunker.com/12552932/alternatives-to-acetone" rel="nofollow noreferrer">Alternatives to Acetone</a>:</p>\n\n<blockquote>\n  <ul>\n  <li>Surfasolve</li>\n  </ul>\n  \n  <blockquote>\n    <p>Surfasolve is a 100 percent biodegradable acetone replacement that removes adhesives, degreases tools and works as a resin solvent.\n    Surfasolve is a non-regulated product.</p>\n  </blockquote>\n  \n  <ul>\n  <li>Bio-Solv</li>\n  </ul>\n  \n  <blockquote>\n    <p>Bio-Solv is an acetone replacement that is 100 percent biodegradable.
