Is a carbon planet with seas of methanol on its surface scientifically possible?

I am creating a carbon planet with seas of methanol on its surface, but I am not sure that this is possible.

It is predicted that carbon planets are depleted of water, since the available oxygen would be depleted by reacting with carbon to mainly form simple compounds such as carbon monoxide, carbon dioxide or carbonate ion. But would something similar happen with low molecular weight alcohols, such as methanol?

According to this work, methanol is formed in molecular clouds mainly in dust grains through the successive hydrogenation of carbon monoxide. And it is destroyed by reacting with the hydronium ion, one of the most abundant ions, produced from water.

I think that, due to the greater amount of carbon available and, therefore, of carbon monoxide, methanol would be more abundant in the medium and due to less amount of water, it would be less prone to dissociation. Considering this, it would be logical to think that a carbon planet with seas of methanol on its surface be possible.

But I am not an expert on this and I have not found papers on it, so I would like to hear suggestions. Is it possible a world like this or could methanol also end up like water?
