Sulphurstan Posted February 28, 2019 Posted February 28, 2019 (edited) Yep, maybe that Cu2O would enhance the result, but my last spectrograms are saying that I face CuOH production, whatever the amount of additional Copper compounds I put in the mix !! I'm still thinking of switching cubenzoate to CuOxal. (Reducing the amount of hydrogen in the initial reagents, compared to benzoate).At the moment,i have no time for pyro, and the few moments I spent recently on this composition by analyzing the spectrum are quite disappointing: the CuCl peaks are indeed seen, but they are also huge CuOH peaks, that "lower" the blue and push the color toward bluish-green, even whitish... I hope to soon find some time to look into the chemistry of the reactions, to see how to avoid the CuOH in the process....."less hydrogen in the reagents, less CuOH in the products"????
