age finds german hundred imposed oils possible similar spices substances taxes trace twenty vegetable
It has been possible to trace historically back to a very early age the taxes which were imposed on medicines, spices and similar substances in German towns. Thus, for instance, one finds that in the year 1500, thirteen, in 1540, thirty-eight, and in 1708, already one hundred and twenty vegetable oils are mentioned.
among behalf bitter carbon caused counted derivative great number properties special substances typical
In bitter almond oil, like in a great number of other substances that previously had been counted among the 'aromatic compounds' on behalf of their strong smell, a derivative of benzene is present. The special properties of benzene and its derivatives are caused by the typical arrangement of their carbon atoms.
oil substance scent
Most of the oils which are valued as scents are mixtures of substances; only the combined effect of these leads to the known result.
molecules tasks substance
As soon as chemists have a definite conception of the internal structure of the molecule of an organic compound, they are able to tackle the task of producing these substances by artificial methods, i.e. by synthesis, as we call it.
