Ketone Color | Bookmark | ||||||
I know there has been quite a few postings about Ketone color, and the wide range of colors. But has anyone definitively figured out why the color can vary? I ask because lately my ketone has been Clear with just a hint of yellow, whereas when the first couple of batches were the standard floro-greenish. The only procedural changes I've made is more washings post-Wacker. |

Same here | Bookmark | ||||||
Most of the time my MDP2P is neon-green. One time it came out almost clear with a hint of yellow. Never blue though. I have never done wacker rxn, only oxone! Washing my impure ketone right after hydrolysis with sat NaHCO3, 3x, lead to distillation of the ketone with VERY LITTLE TAR (less than 1 gram), and light yellow ketone. This was the best Ketone swim ever made. (smelled the best too!) |

ketone can be blue and still react quite well, | Bookmark | ||||||
ketone can be blue and still react quite well, search rhodiums site and I know from personal experience the blue color apperently comes from impure safrole |

I Know That Different Color Ketones | Bookmark | ||||||
from experience, aminate OK, but my question is what actually causes the different colors. I thought I saw a post one time that alluded to the Neon-Green color being caused by Palladium by-products, and could be eliminated by adding some activated charcoal to the Ketone. Maybe I should have phrased my question: "What SHOULD the color of ketone be?" |

Ketone should be pure as far as i know,colour... | Bookmark | ||||||
Ketone should be pure as far as i know,colour doesn't matter as the stuff that makes ketone green,for example,doesn't even make up 1% of neon-green ketone.Colour is because of traces of some other material. For those about to synth,we salute you |
