In accordance with the method of Garbrecht (144), the lithium salt of lysergic acid is converted in dimethylformamide solution with SO3 to form the mixed lysergic acid sulfuric acid anhydride which reacts with primary or secondary amines to give a good yield of the corresponding lysergic acid amides.

Several molecules are held together to become an indivisible molecule because the diatomic radical of sulfuric acid rearranges itself in such a way that one half of it takes the place of the typical hydrogen. This is by far the most common case it is exactly the same process which causes the formation of sulfuric acid hydrate from sulfuric acid anhydride and water, and the formation of Nordhauser s oil of vitriol from sulfuric acid anhydride and hydrate. For instance ... [Pg.121]

It then appears analogous to benzenesulfonic acid (as methylcarbonic acid). The remarkable preparation of propionic acid by action of carbon dioxide on cthylsodium, which has very recently been discovered by WanMyn, can then be understood in the same way as the formation of benzenesulfonic acid from benzene and sulfuric acid anhydride.

END USES... Sulfur dioxide, sulfurous acid anhydride, is a non-flammable, colorless gas at normal ambient temperature with a characteristic pungent odor. It is supplied as a water clear liquid-compressed gas with a purity of 99.98%. The commercial grade containing not more than 0.05% moisture is suitable for most applications. It has a boiling point of 14 °F. [Pg.47]
