Descriptions for C07B and notes/indexes are displayed on this screen.


Note(s)
    In this subclass, a functional group which is already present in some residue being introduced and is not substantially involved in a chemical reaction, is not considered as the functional group which is formed or introduced as a result of the chemical reaction [4,8]In this subclass, the following term is used with the meaning indicated:
      "separation" means separation only for the purposes of recovering organic compounds 
    When classifying in this subclass, classification is also made in group B01D 15/08—insofar as subject matter of general interest relating to chromatography is concerned In this subclass, the last place priority rule is applied, i.e. at each hierarchical level, in the absence of an indication to the contrary, classification is made in the last appropriate place according to the type of reaction employed, noting the bond or the functional group which is formed or introduced as a result of the chemical reaction
