Application of 18531-99-2, In heterogeneous catalysis, the catalyst is in a different phase from the reactants. At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 18531-99-2, name is (S)-[1,1′-Binaphthalene]-2,2′-diol. In an article，Which mentioned a new discovery about 18531-99-2
Enantiomer separation of rac-2,2?-dihydroxy-1,1?-binaphthyl (BNO) by inclusion complexation with racemic or achiral ammonium salts and a novel transformation of a 1:1:1 racemic complex of BNO, Me4N +·Cl- and MeOH into a conglomerate complex in the solid state
The complete simultaneous and mutual enantiomer resolution of 2,2?-dihydroxy-1,1?-binaphthyl (BNO) and N-(3-chloro-2- hydroxypropyl)-N,N,N-trimethylammonium chloride, Me3N +CH2CH(OH)CH2Cl·Cl- into their enantiomers by inclusion complexation between their racemates in EtOH in the presence of a chiral seed crystal is reported. The enantiomer resolution of the rac-BNO was also accomplished easily by inclusion complexation with achiral ammonium salts, N-(2-hydroxyethyl)-N,N,N-trimethylammonium chloride, Me 3N+CH2CH2OH·Cl- and tetramethylammonium chloride, Me4N+·Cl -. Inclusion complexation of the rac-BNO with Me3N + CH2CH2OH·Cl- gave only a 1:1 conglomerate inclusion complex but not a racemic complex. Recrystallization of the rac-BNO and an equimolar amount of Me4N+· Cl- from MeOH (7 ml) and MeOH (15 ml) gave a 1:1:1 racemic complex, BNO·Me4N+·Cl-·MeOH and a 1:1 conglomerate complex, BNO·Me4N+·Cl -, respectively. Novel transformation of the former racemate into the latter conglomerate occurred by heating or by exposure to MeOH vapor in the solid state.
Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.18531-99-2. In my other articles, you can also check out more blogs about 18531-99-2
