Dmso Decomposition

We found that DMSO is not dissolving PO, but rather reacting with it. A rather complex mixture of phosphate species is formed, many with ester functions.

The kinetics of the oxidation of DMSO in a mix- ture of Na2W04 and H202 were measured iodomet- rically in aqueous buffers of various pH values. Since the decomposition of H202 in the presence of Na2W04 at pH over 4.0 was appreciable, the rate of oxidation of DMSO was calculated by subtracting the rate of the decomposition of H202 from the

The thermal decomposition of glycerol and propylene glycol is typical of alcohols and has been investigated, although not exhaustively. In this work, samples of propylene glycol and glycerol were vaporized using an electronic cigarette (e-cigarette) and were analyzed for evidence of decomposition using

Although the decomposition mechanism of DMSO under acidic conditions is known (Santosusso et al. in Tetrahedron Lett 48:4255–4258, 1974), the number of studies about thermal behavior of DMSO.

Experimental results demonstrated that acidic conditions favored the degradation of DMSO and increased the mass of DMSO decomposition per unit mass of.
