What is "superbase"

n. (context chemistry English) any compound having a very high basicity

In chemistry, a superbase is an extremely basic compound or substance that has a high affinity for protons. The hydroxide ion is the strongest base possible in aqueous solutions, but bases exist with much greater strengths than can exist in water. Such bases are valuable in organic synthesis and are fundamental to physical organic chemistry. Superbases have been described and used since the 1850s. Reactions involving superbases often require special techniques since they are destroyed by water and atmospheric carbon dioxide as well as oxygen. Inert atmosphere techniques and low temperatures minimize these side reactions. Superbases also have a corrosive effect.

Superbase is an end-user desktop database program that started on the Commodore 64 and was ported from that to various operating systems over the course of more than 20 years. It also has generally included a programming language to automate database-oriented tasks, and with later versions included WYSIWYG form and report designers as well as more sophisticated programming capabilities.
