    Abundances are given as pollution free monthly mean mole fractions in parts-per-trillion. Dichloromethane is not classified as an ozone-depleting substance by the Montreal Protocol. [43] The US Clean Air Act does not regulate dichloromethane as an ozone depleter. [44] Dichloromethane has been classified as a very short-lived substance (VSLS).

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

    Methyldichlorophosphine is produced by alkylation of phosphorus trichloride with methyl iodide followed by reduction of the resulting phosphonium salt with iron powder: [2] [3] CH 3 I + PCl 3 + AlCl 3 → [CH 3 PCl 3 ] + AlCl 3 I −

  9. Methylphosphonyl dichloride - Wikipedia

    en.wikipedia.org/wiki/Methylphosphonyl_dichloride

    Methylphosphonyl dichloride (DC) or dichloro is an organophosphorus compound. It has commercial application in oligonucleotide synthesis, [1] but is most notable as being a precursor to several chemical weapons agents. It is a white crystalline solid that melts slightly above room temperature. [2]
