WebThe normal melting and boiling points for methanol (CH 3 OH) are 175.7 K and 337.8 K, respectively. The critical temperature and pressure are 512.8 K and 81 bar. The triple … Small amounts of methanol are present in normal, healthy human individuals. One study found a mean of 4.5 ppm in the exhaled breath of test subjects. The mean endogenous methanol in humans of 0.45 g/d may be metabolized from pectin found in fruit; one kilogram of apple produces up to 1.4 g of pectin (0.6 g of methanol.) Methanol is produced by anaerobic bacteria and phytoplankton.
