Some  Derivatives  of  Chimaphilin.  {Al 
From  this  purified  chimaphilin  the  following  compounds  were 
prepared : 
Pure  dry  chlorine  gas  was  conducted  through  a  solution  of  the 
crystals  in  absolute  ether.  The  reddish-yellow  color  of  the  solution 
gradually  became  paler,  until  at  the  end  of  three  hours  it  retained 
but  a  light  yellow  tint. 
Nothing  was  deposited  from  the  solution  so  treated,  but,  upon 
the  spontaneous  evaporation  of  the  ether,  tufts  of  light-yellow- 
colored,  needle-shaped  crystals  remained.  They  melted  between 
93°  and  940  C,  thus  showing  their  difference  from  chimaphilin. 
They  were  soluble,  to  some  extent,  in  a  10  per  cent,  solution  ot 
potassium  hydrate,  to  which  they  imparted  a  faint  pink  color,  which, 
upon  heating,  changed  to  yellow.  When  their  solution  in  potassium 
hydrate  was  acidified  with  nitric  acid  and  tested  with  silver  nitrate, 
a  distinct  precipitate  of  silver  chloride  was  obtained.  The  action 
of  ammonium  hydrate  was  similar  to  that  of  potassium  hydrate. 
A  combustion  of  the  derivative  (silver-foil  being  used  to  absorb 
the  chlorine),  afforded  the  following  figures : 
Carbon   54*33  per  cent. 
Hydrogen  4*63  " 
To  estimate  the  chlorine,  a  mixture  of  the  derivative  and  calcium 
carbonate  was  heated  to  redness  in  a  piece  of  combustion  tubing 
for  one  hour.    The  tube  was  allowed  to  cool,  then  broken,  and  its 
entire  contents  treated  with  water,  and  afterwards  with  nitric  acid 
in  excess.    The  solution  was  filtered  from  the  fragments  of  glass, 
and  completely  precipitated  with  silver  nitrate.  The  resulting  silver 
chloride  was  collected,  washed,  and  subsequently  dried  at  1 300  C. 
Its  amount  indicated  the  presence  of  28-22  per  cent,  of  chlorine  in 
the  derivative. 
It  would  therefore  appear,  from  the  results  obtained  by  analysis, 
that  this  compound  is  a  tetra-chlor  addition  product  of  C24H2104, 
and,  for  convenience  of  comparison,  the  matter  may  be  tabulated  as 
CHLORINE  DERIVATIVE.
