In chemistry , a superbase is an extremely strong base . How strong a base has to be in order to be considered a "superbase" is not clearly defined - sodium hydroxide is often used as a yardstick (so a superbase would be a base that is stronger than sodium hydroxide), as is often the case for the definition of superacid the sulfuric acid is used as a benchmark.

Since sodium hydroxide with a pK _s value true of ~ 14 even as a strong base should be exercised in the handling of super bases unconditional caution because even brief contact could cause the skin to irreparable damage.

There are three main classes that superbases are divided into: organic superbases, organometallic superbases, and inorganic superbases (which are typically salts with highly charged anions).

Examples of superbases

• Organic superbases are the proton sponges such as B. 1,8-bis (dimethylamino) naphthalene.
• The Lochmann-Schlosser-Base is an organometallic superbase .
• An example of an inorganic superbase is lithium nitride .
• Further examples of (organic) superbases are alcoholates ( pKa * value ~ 26) and lithium diisopropylamide (LDA, pKa * value 35–40).
