2RSH+½02→RSSR+H20 Mercaptans are extracted from organic phase by strongly alkali aqueous solutions, in which at elevated temperature and pressure catalytical oxidation of mercaptans takes place, and as a catalyst salts from metals of alternating valency (Fe, Co, Ni, V, Mn, Cr) in the...
The day we had to say a final goodbye, I went early. Before anyone else. To have my time with you. Unfortunately, I didn’t realize what my guttural reaction would be. Shiv had to ask the people there to remove all signs of your name, all pictures, anything that would set me off...
Method B (base‑catalyzed) The general procedure Claisen–Schmidt condensation reaction was used to synthesize curcuminoids by using this method involved in addition of certain amount of mono ketone (cyclohexanone, acetone and cyclopen- tanone) to a solution of substituted aldehydes in MeOH or ...
The transition states (TS) are investigated by the QST3 method of Gaussian 98 package and demonstrated with Intrinsic reaction coordinate (IRC). It is found that K+@Si20H20 cluster has the most stable structure kinetically, that the exit barrier heights (Hexit) for K+ expulsion from or ...
