yield time three-necked place registers
collect distill solution
  • _____________ 100 g. (115.5 ml) of dry toluene
    and a few chips of porous plate in the flask.
    Boil the toluene gently and pass in a stream of
    chlorine from a cylinder (or from a gas
    generator) (Interpose an empty wash bottle
    between the flask and the gas source) until the
    thermometer _____________ 157-158 (1). The

    shortened by exposing the mixture to bright
    sunlight or to a small mercury-vapour lamp or any
    other UV lamp.
  • Transfer the reaction mixture to a Claisen flask
    and distil under atmospheric pressure until the
    temperature reaches 135-140 (2).
    ________________the residue under diminished
    pressure and ______________ the benzyl chloride
