  2. 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]

    Due to the recycling problem of phosphoryl chloride, SW was adopted in step three of the DMHP process in the preparation of Sarin. [5] SW was also adopted as a standard precursor to V agents, having been used to prepare QL for unitary and binary VX. SW was the first agent adopted to prepare VX in one pot reaction by aqueous medium. [6]

    en.wikipedia.org/wiki/Methylphosphonic_acid

    Methylphosphonic acid is an organophosphorus compound with the chemical formula CH 3 P(O)(OH) 2. The phosphorus center is tetrahedral and is bonded to a methyl group, two OH groups and an oxygen. Methylphosphonic acid is a white, non-volatile solid that is poorly soluble in organic solvent but soluble in water and common alcohols.

    A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.

  9. Dichlorophenylphosphine - Wikipedia

    en.wikipedia.org/wiki/Dichlorophenylphosphine

    The compound is an intermediate for the synthesis of other chemicals for instance dimethylphenylphosphine: C 6 H 5 PCl 2 + 2 CH 3 MgI → C 6 H 5 P(CH 3) 2 + 2 MgICl. Many tertiary phosphines can be prepared by this route. [3] In the McCormack reaction dichlorophenylphosphine adds dienes to give the chlorophospholenium ring. [4]
