But this is by no means so. Otto Wallach oil mean thinking Most of the oils which are valued as scents are mixtures of substances; only the combined effect of these leads to the known result. Otto Wallach scent oil substance As soon as science has solved one problem, new ones arise. This is the essence of science, and it applies, of course, also to the field of essential oils. Otto Wallach essential-oils essentials essence 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. Otto Wallach molecules tasks substance May the work for the further development of chemical science, which has its strongest roots in this beautiful, strong and hard-working country of Sweden, continue to flourish in the future, for the promotion of culture and the benefit of mankind. Otto Wallach strong beautiful country 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.

The special properties of benzene and its derivatives are caused by the typical arrangement of their carbon atoms. Otto Wallach great smell strong special As soon as we can wrest from Nature the secret of the internal structure of the compounds produced by her, chemical science can then even surpass Nature by producing compounds as variations of the natural ones, which the living cell is unable to construct.
