In heterogeneous catalysis, catalysts provide a surface to which reactants bind in a process of adsorption. In homogeneous catalysis, catalysts are in the same phase as the reactants. Quality Control of Hemin. Catalysts allow a reaction to proceed via a pathway that has a lower activation energy than the uncatalyzed reaction. Introducing a new discovery about 16009-13-5, Name is Hemin
A protoporphyrin disodium preparation method (by machine translation)
The present invention provides a kind of protoporphyrin disodium preparation method, which belongs to the field of synthetic organic compounds, comprising the following steps: the protoporphyrin, anhydrous methanol and concentrated sulfuric acid is in ultrasonic under the condition of alkyd reaction, to obtain the protoporphyrin diester; the protoporphyrin diester, NaOH methanol solution and toluene in the ultrasonic under the condition of saponification reaction, to obtain the protoporphyrin disodium. This invention adopts the ultrasonic auxiliary replacing high temperature reflow, preparation of the protoporphyrin disodium, the preparation process is not needed in the preparation of the hydrogen chloride gas and also avoid the use of chloroform strong toxic reagent, also does not need to use high-temperature conditions, the process is simplified, the whole process is easy to operate.
