Application of 33100-27-5, Children learn through play, and they learn more than adults might expect. Science experiments are a great way to spark their curiosity, get their minds active, and encourage them to do something that doesn’t involve a screen. 33100-27-5, C10H20O5. A document type is Article, introducing its new discovery.

The complex formation between unprotonated and protonated aniline and aminobenzo crown ethers with different crown ethers has been studied using calorimetric titrations. The results clearly show that the self complexation of protonated aminobenzo crown ethers takes place in solution. One protonated amino group of an aminobenzo crown ether is complexed by the crown ether part of another aminobenzo crown ether. If this crown ether part id 15C5 only weak complexes are formed. In the case of aminobenzo-18-crown-6 the self-complexation is really strong. The reaction enthalpy for the self complexation of aminobenzo-18-crown-6 can be calculated indirectly to be -23.0 +/- 1.7 kJ/mol.
