Chemical Transformation Quotes

If you have acid in food, you need to sugar it. At a high temperature, the acids are changed to sugar.

Although the problem of transmuting chemical elements into each other is much older than a satisfactory definition of the very concept of chemical element, it is well known that the first and most important step towards its solution was made only nineteen years ago by the late Lord Rutherford, who started the method of the nuclear bombardments.

Most commercial products that contain organic molecules possess at least one carbon-carbon double bond, or if one is not present, it is likely that an olefin was used in its preparation. This being the case, the potential applications of olefin metathesis are endless.

The distinction between the old and the new formulations consisting in the incorporation of the concept of the rate of chemical reactions is so great that it immediately asserted itself in the objective development of catalysis.

The problem is how do molecules react. Because if you want to transform a molecule into something useful or something you're interested in, it helps a lot to understand the structure. That means you can explore much more complicated systems, much more complicated reactions.

Salt water when it turns into vapour becomes sweet, and the vapour does not form salt water when it condenses again. This I know by experiment. The same thing is true in every case of the kind: wine and all fluids that evaporate and condense back into a liquid state become water. They all are water modified by a certain admixture, the nature of which determines their flavour.

I will roar argon into chlorine, xenon into fluorine, all the noble gases into reactive ones My lament will terrify even the stars.

When we passed a Catholic church, I recalled, he said, "You think your dad's a good chemist? They're turning soda crackers into meat in there. Can your dad do that?

Sulfur, when burning, absorbs oxygen gas; the resulting acid is considerably heavier than the sulfur burned; its weight is equal to the sum of weights of the sulfur burned and the oxygen absorbed.

I was also interested in formulating the path of chemical reactions.

The first entirely vital action, so termed because it is not effected outside the influence of life, consists in the creation of the glycogenic material in the living hepatic tissue. The second entirely chemical action, which can be effected outside the influence of life, consists in the transformation of the glycogenic material into sugar by means of a ferment.

The trade of chemist (fortified, in my case, by the experience of Auschwitz), teaches you to overcome, indeed to ignore, certain revulsions that are neither necessary or congenital: matter is matter, neither noble nor vile, infinitely transformable, and its proximate origin is of no importance whatsoever. Nitrogen is nitrogen, it passes miraculously from the air into plants, from these into animals, and from animals into us; when its function in our body is exhausted, we eliminate it, but it still remains nitrogen, aseptic, innocent.

Everything has its limit - iron ore cannot be educated into gold.

When oxygen and sulphur dioxide are mixed in the presence of a filiament of platinum, they form sulphurous acid. This combination takes place only if the platinum is present; nevertheless the newly formed acid contains no trace of platinum, and the platinum itself is apparently unaffected: has remained inert, neutral, and unchanged. The mind of the poet is the shred of platinum.

Chlorine is a deadly poison gas employed on European battlefields in World War I. Sodium is a corrosive metal which burns upon contact with water. Together they make a placid and unpoisonous material, table salt. Why each of these substances has the properties it does is a subject called chemistry.

Bacteria mineralized the rocks; they deposited the iron. They made the geology we see.

My own ideas on the mechanism of catalytic phenomena were very different from those at one time commonly held, ideas which I no doubt owed to the influence of the illustrious teacher who had guided my first steps in chemistry nearly twenty years before - I refer, of course, to Berthelot.

But in this Second Work if thou extract our Air and our Fire with the phlegm water, they will the more naturally and easily be drawn out of their infernal prison, and with less losse of their Spirits, than by the former way before described.

This is alchemy, and this is the office of Vulcan; he is the apothecary and chemist of the medicine.

Life does depend on accurate replication of molecules, and its complexity often requires that an enzyme shall accept one molecular species or type and transform it to equally specific products.

While I thought myself employed only in forming a nomenclature, and while I proposed to myself nothing more than to improve the chemical language, my work transformed itself by degrees, without my being able to prevent it, into a treatise upon the Elements of Chemistry.

Nature is a rag-merchant, who works up every shred and ort and end into new creations; like a good chemist, whom I found, the other day, in his laboratory, converting his old shirts into pure white sugar.
