ANHYDROUS  VALERIANIC  ACID. 
The  preceding  compounds  are  not  the  only  ones  furnished  by 
glycerine.  I  have  already  obtained  several  others,  and  hope  to 
succeed  in  reproducing  margarine  and  stearine,  the  most  important 
of  the  glycerine  compounds,  and  the  principal  constituents  of  the 
natural  fatty  substances. — Lond.  Chem.  Gaz.,  April  1,  1853,  from

ANHYDROUS  VALERIANIC  ACID. 
Chiozza  has  obtained  anhydrous  valerianic  acid  by  the  method 
which  Gerhardt  has  applied  to  the  isolation  of  acetic  and  butyric 
acids.  When  oxychlorid  of  phosphorous,  P  Cl3  02,  is  brought  into 
contact  with  valerianate  of  potash,  a  violent  reaction  takes  place 
and  the  odor  of  the  oxychlorid  disappears.  By  treating  the  mass 
with  a  weak  solution  of  carbonate  of  potash,  and  then  with  ether, 
and  evaporating  the  ethereal  solution,  the  anhydrous  acid  is  ob- 
tained as  a  limpid,  highly  mobile  liquid,  lighter  than  water,  and 
possessing  a  feeble  odor  of  apples.  The  liquid  boils  at  215°,  and 
distills  over  perfectly  colorless  :  its  vapor  irritates  the  eyes  and 
provokes  coughing.  The  reaction  by  which  the  anhydrous  vale- 
rianic acid  is  obtained,  is  represented  by  the  equations, 
PCl30o+3(C10H903,  KO)=P05  3KO+3(C10HAC1) 
3(C10  HA,  KO)+3(C10  HACl)=3KCl+3(C10H9O3) 
the  oxychlorid  of  valeryl,  C10H902C1,  is  here  first  set  free  and  then 
reacts  on  another  portion  of  valerianate  of  potash. 
By  the  action  of  oxychlorid  of  benzoyl  on  valerianate  of  potash 
the  author  has  also  obtained  a  compound  of  anhydrous  valerianic 
with  anhydrous  benzoic  acid  represented  by  Cl0  H903+C14H503. 
It  is  an  oily  liquid,  heavier  than  water,  and  leaving  an  odor  like 
that  of  anhydrous  valerianic  acid.  By  distillation  it  is  separated 
into  anhydrous  benzoic  and  anhydrous  valerianic  acids.  Alkaline 
solutions  transform  it  into  valerianates  and  benzoates. 
By  the  action  of  aniline  upon  anhydrous  valerianic  acid  Chiozza 
has  prepared  valeranilide  crystallizing  in  magnificent  rectangular 
tables  fusing  at  115°  C.  Its  formula  is  N  C12  Hs,  C10HqO2. — -
