Dynamical properties of water-methanol solutions.
We study the relaxation times tα in the water-methanol system. We examine new data and data from the literature in the large temperature range 163 < T < 335 K obtained using different experimental techniques and focus on how tα affects the hydrogen bond structure of the system and the hydrophobicity of the alcohol methyl group. We examine the relaxation times at a fixed temperature as a functio...
متن کاملAnalysis of Separation of Water-methanol- Formaldehyde Mixture
The vacuum distillation of methanol from aqueous formaldehyde solution is an important step in the production of formaldehyde by silver process. In this work the separation of this reactive threecomponent mixture is discussed. Physico-chemical phase equilibrium model proposed by Maurer was used in order to investigate the influence of some operating parameters on the performance of the column. ...
متن کاملThe Origin of Hydrogen Generated from Formaldehyde in Basic Solutions
The isotopic composition of dihydrogen generated from formaldehyde in highly basic solutions has been investigated. It is shown that two pathways contribute to the generation of dihydrogen. In the f i s t pathway, one hydrogen atom originates from water and the other from formaldehyde. In the second pathway both hydrogen atoms originate from the methylene moiety of the formaldehyde. For product...
متن کاملOxidative Dehydrogenation of Methanol to Formaldehyde’
is not favorable (AH = + 3 1.5 kcal). Our conclusion is that an important catalytic site involves two adjacent surface dioxo units (the dual dioxo site), with each dioxo site extracting one H in a sequence of steps. The required dual dioxo site exists on the (010) surface of MOO, but does not exist on the other low index surfaces. This mechanism is supported by atmospheric pressure experimental...
