  4. Formaldehyde - Wikipedia

    en.wikipedia.org/wiki/Formaldehyde

    In the commonly used formox process, methanol and oxygen react at c. 250–400 °C in presence of iron oxide in combination with molybdenum and/or vanadium to produce formaldehyde according to the chemical equation: [40] 2 CH 3 OH + O 2 → 2 CH 2 O + 2 H 2 O. The silver-based catalyst usually operates at a higher temperature, about 650 °C.

    en.wikipedia.org/wiki/Azeotrope_tables

    This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.

    The compound is closely related and convertible to the industrially significant derivatives paraformaldehyde ((CH 2 O) n), formaldehyde (H 2 C=O), and 1,3,5-trioxane ((CH 2 O) 3). [3] Methanediol is a product of the hydration of formaldehyde. The equilibrium constant for hydration is estimated to be 10 3, [4] CH 2 (OH) 2 predominates in dilute ...

  8. Boiling-point elevation - Wikipedia

    en.wikipedia.org/wiki/Boiling-point_elevation

    The result is that in dilute ideal solutions, the extent of boiling-point elevation is directly proportional to the molal concentration (amount of substance per mass) of the solution according to the equation: [2] ΔT b = K b · b c. where the boiling point elevation, is defined as T b (solution) − T b (pure solvent).

  9. Boiling point - Wikipedia

    en.wikipedia.org/wiki/Boiling_point

    Water boiling at 99.3 °C (210.8 °F) at 215 m (705 ft) elevation. The boiling point of a substance is the temperature at which the vapor pressure of a liquid equals the pressure surrounding the liquid [1] [2] and the liquid changes into a vapor.
