In heterogeneous catalysis, the catalyst is in a different phase from the reactants. HPLC of Formula: C28H30O4, At least one of the reactants interacts with the solid surface in a physical process called adsorption in such a way. 125-20-2, name is Thymolphthalein. In an article，Which mentioned a new discovery about 125-20-2
The interactions of cyclomalto-octaose (gamma-cyclodextrin) with some phthalein-type acid-base indicators have been investigated photometrically.Bromine substituents enhance the formation of complexes and tetrabromophenolphthalein <3,3-bis(3,5-dibromo-4-hydroxyphenyl)-3H-isobenzofuran-1-one> forms the most stable complex (K 6.0 x 1E3).This stability and other phenomena suggest that the host and guest are involved in a three-site interaction.
I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 125-20-2, help many people in the next few years.HPLC of Formula: C28H30O4
