Question

Compare the advantages and disadvantages of methyl alcohol and glycerin as antifreeze substances in automobile radiators.

Answer 1

Antifreeze, any substance that lowers the freezing point of water.

Glycerol has the advantage of being non-toxic, withstands relatively high and low temperatures, and is non-corrosive and non-toxic. It is not however used widely due to its costs.

Methanol is relatively cheap and has a low freezing point. However, methanol is very toxic and its boiling point is low comparing to glycerol and ethylene glycol.
