  • Highly concentrated formaldehyde solution, production and reaction thereof
    Patent number: 7193115
    Abstract: In an aqueous formaldehyde solution comprising formaldehyde in the form of monomeric formaldehyde, methylene glycol and polyoxymethylene glycols in a total concentration x of ?65% by weight, the mean molar mass M of the polyoxymethylene glycols is, as a function of the formaldehyde concentration, equal to or less than the values given by equation I: ( M _ g ? / ? mol ) = 48 + 6.589 · 10 - 1 · ( x % ? ? by ? ? weight ) + 4.725 · 10 2 · ? ( x % ? ? by ? ? weight ) 2 - 3.434 · 10 - 3 · ( x % ? ? by ? ? weight ) 3 + ? 9.625 · 10 - 5 · ( x % ? ? by ? ? weight ) 4 - 1.172 · 10 6 · ? ( x % ? ? by ? ? weight ) 5 + 5.

    Abstract: In an aqueous formaldehyde solution comprising formaldehyde in the form of monomeric formaldehyde, methylene glycol and polyoxymethylene glycols in a total concentration x of ?65% by weight, the mean molar mass {overscore (M)} of the polyoxymethylene glycols is, as a function of the formaldehyde concentration, equal to or less than the values given by equation I: ( M _ g / mol ) = 48 + 6.589 · 10 - 1 · ( x % ? ? ? by ? ? ? weight ) + 4.725 · 10 2 · ? ? ( x % ? ? ? by ? ? ? weight ) 2 - 3.434 · 10 - 3 · ( x % ? ? ? by ? ? ? weight ) 3 + ? ? 9.625 · 10 - 5 · ( x % ? ? ? by ? ? ? weight ) 4 - 1.172 · 10 6 · ? ? ( x % ? ? ? by ? ? ? weight ) 5 + 5.
