Organic bases acidic substances

This is an example of a general reaction. If acetic acid is used as a solvent, the substituted malonic acids can be secured, whereas organic bases facilitate the loss of carbon dioxide. The product is generally a mixture from which but a single substance can be isolated. [Pg.109]

When Boyle began his scientific work, chemistry was not yet a science. The complexity of the materials with which chemists worked made generalizations about their behavior difficult. There was no standard chemical terminology and no concept of chemical purity. Paracelsus had tried to use chemical preparations that were as pure as possible but most who succeeded him didn t bother. No distinction was made between organic and inorganic substances, and there was no clear understanding of the difference between acids, bases, and salts. [Pg.53]

As we have discussed before, Lewis defined acids as compounds prepared to accept electron pairs and bases as substances that could provide such pairs. In organic reactions one speaks of electrophiles and nucleophiles. [Pg.710]

A similar principle applies to the desorption of organic acids and organic bases. In this case, the pH of the system is adjusted so as to convert the adsorbed substance to the less adsorbable salt form. In most cases this procedure is only partially successful because many organic salts are hydrolytically adsorbed to some extent and such portions remain on the carbon. [Pg.245]
