  1. This page defines an alcohol, and explains the differences between primary, secondary and tertiary alcohols. It examines in some detail their simple physical properties such as solubility and boiling points.

  2. 8 Ιουλ 2020 · The aggregates of methanol and ethanol in highly concentrated solutions form an extended H-bond network that intertwines well with the H-bond network of water. n -Butanol tends to self-associate and form large aggregates, while such aggregates are segregated from water.

  3. 4 Αυγ 2021 · In this chapter, we present a comparative study of dynamics in three types of alcohol–water mixtures: methanolwater, ethanol–water, and 1-propanol–water. These mixtures are known for micro-heterogeneous structure, which is usually explained...

  4. 15 Νοε 2023 · In the ethanol–water solution (E-Ws), the hydrogen bonds (HBs) of W (H)∙∙∙E (O) or E (H)∙∙∙W (O) are readily formed when the spatial orientation of them are match. However, in general, ethanol has proven to be a better HB donor than water, and even a better HB acceptor [29].

  5. 1 Μαΐ 2011 · Vapourliquid equilibrium diagram for alcoholwater binary mixtures: methanol–water (blue), ethanol–water (red), 1-propanol–water (green) and 1-butanol–water (yellow). The diagram graphs liquid mole fraction of alcohols (x) and vapour mole fraction of alcohols (y).

  6. 1 Μαΐ 2024 · Alcoholic beverages are conventionally classified by alcohol by volume (ABV) based on ethanol-water mixture (EWM) concentrations, which is regarded as empirical with little scientific explanation. Here, we find that contact angles of EWMs with different ethanol fractions on highly oriented pyrolytic graphite are non-linear but steplike, while ...

  7. 25 Απρ 2002 · Here we use neutron diffraction with isotope substitution to probe the molecular-scale structure of a concentrated alcoholwater mixture (7:3 molar ratio).
