    Thermal properties of methanol
    Hi

    Can anyone provide data on the thermal behaviour of methanol in the 120C to 170C temperature range. We are heating methol (99.9% purity) in a sealed and evacuated high purity copper tube. There appears to be some degradation of the methanol. Is there a temperature at which methanol might breakdown into component parts ?

    Thank you

    Perito

    I'm sure that methanol will decompose. If there's nothing else in the vessel, it will decompose to form H2 and CO



    Copper is a catalyst for the reaction, though the temperature that they quote here is 240 C.

    SpringerLink - Journal Article

    There will probably also be some side reactions that will form formaldehyde and water and maybe some other cats and dogs.

    Look for papers citing DSC measurements.
