Verwenden

Benzo-15-crown-5 is used in synthetic chemistry. It plays a major role and involved in complexation through ether oxygen. It is used in phase-transfer catalyst system. It is involved in 'Host-Guest' chemistry to identify the move of essential elements in the body. It can play the part of very complicated biological reactions such as enzyme functions, which finds application in the development of new pharmaceuticals.

Application

Benzo-15-crown-5 can be used for sol-gel material extraction to separate lithium isotopes, for making static detection sensors for formic acid gases, and as metal ion complexing agent and phase transfer reagent.

synthetische

synthesis of Benzo-15-crown-5: benzo-15-crown-5 can be produced using Williamson synthesis reaction, featured by interaction between catechol (orto-dihydroxybenzene) and tetraethylene glycol dichloride (1,10-dichloro-3,6,9-trioxadecane) over sodium hydroxide in the n-butanol media (30-h inertatmosphere boiling). The yield of benzo-15-crown-5 produced by this method is 62%, with the basic substance's mass fraction of 95%.
