"In chemistry, as in war, victory belongs to the side that makes more observations."
In this quote, Otto Wallach suggests that success in both chemistry and warfare is contingent upon the quantity of observations made. This means that gathering extensive data (observations) and analyzing it effectively can provide a competitive advantage in any field, as a greater understanding of the situation allows for more informed decision-making and strategies. Essentially, the side that learns and adapts from their experiences will have an edge over others.
"The progress of chemical research is often likened to the exploration of unknown lands; it consists of opening up new regions and conquering them step by step."
This quote by Otto Wallach emphasizes that the advancement in chemical research, much like the discovery and colonization of new territories, involves an exploratory process of uncharted territory. It signifies the continuous effort to expand our knowledge and understanding of the unknown, gradually conquering each step with new discoveries and insights, ultimately leading to progress in the field.
"The discovery and isolation of a substance are the two fundamental operations in chemistry."
This quote emphasizes that discovery and isolation of a substance are the essential steps in the chemical process. Discovery refers to identifying a new substance, while isolation signifies separating it from other substances so it can be studied independently, thus advancing our understanding of its properties and behavior. In other words, the statement highlights the importance of identification and purification in the field of chemistry.
"One should not seek to isolate individual processes from one another, but rather consider complex reactions as a whole."
This quote by Otto Wallach emphasizes the importance of understanding chemical reactions holistically rather than focusing on individual processes in isolation. It suggests that complex chemical transformations are interconnected, and for a comprehensive grasp, we should examine them as an integrated whole instead of analyzing each part separately. This perspective can help us uncover intricate relationships between various steps involved in chemical reactions, leading to deeper insights into the mechanisms underlying these transformations.
"It is not possible to make a clean sweep of all existing knowledge; what is necessary is to build upon it and advance step by step."
The quote emphasizes that progress in knowledge, particularly in science, doesn't involve erasing or discarding previous knowledge but rather building upon it. It suggests an iterative process of refining, expanding, and advancing our understanding of the world one step at a time. In essence, Wallach is urging us to learn from the past, use that foundation to move forward, and continually strive for improvement in our pursuit of knowledge and truth.
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.

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.
