Reference of 2687-12-9, Redox catalysis has been broadly utilized in electrochemical synthesis due to its kinetic advantages over direct electrolysis. The appropriate choice of redox mediator can avoid electrode passivation and overpotential. 2687-12-9, Name is Cinnamyl chloride, SMILES is ClCC=CC1=CC=CC=C1, belongs to chlorides-buliding-blocks compound. In a article, author is Nimmervoll, Manuela, introduce new discover of the category.

In this paper the corrosion behavior of high temperature corrosion resistant alloys is investigated in a gas atmosphere containing HCl and H2S at 480 degrees C and 680 degrees C. By considering the vapor pressures of the metal chlorides and the water gas shift reaction, as well as the influence of H2S, the different corrosion behavior at 480 degrees C compared to 680 degrees C can be explained and a model of the course of corrosion is proposed. Corrosion tests were performed for 240 h with the austenitic stainless steels S31400 (20 wt% Ni) and N08811 (30.4 wt% Ni) and with the Ni-based alloy N06600 (72.5 wt% Ni). It could be shown that with increasing Ni-content in the alloy, the corrosion rate at high temperatures decreased, but this effect could no longer be observed at lower temperatures. While for N08811 and N06600 the mass loss was lower at 680 degrees C, it increased at temperatures of 480 degrees C. In the case of S31400 the mass loss increased with rising temperature.

Reference of 2687-12-9, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 2687-12-9 is helpful to your research.
