WebWhat the triiodomethane (iodoform) reaction shows. A positive result - the pale yellow precipitate of triiodomethane (iodoform) - is given by an aldehyde or ketone containing the grouping: "R" can be a hydrogen atom or a hydrocarbon group (for example, an alkyl group). If "R" is hydrogen, then you have the aldehyde ethanal, CH 3 CHO. WebMethyl Iodide has a boiling point of 41C to 43C and specific gravity of about 2.27. Methyl Iodide is sensitive to light and therefore needs to be stored in dark amber colored bottles to prevent its degradation by light. Iodomethane may be stabilized by copper or silver wire. Specifications - Methyl Iodide or Iodomethane: Molecular formula: CH3I WebIodomethane is colorless, however, samples take on a reddish hue when exposed to light. Rice crops naturally emit modest amounts of it. Algae and kelp in the world’s temperate oceans create huge amounts of it, estimated to be more than 214,000 tons per year, and terrestrial fungus and bacteria create smaller amounts on land. clothes dryer brandsmart
