An ethanol-water solution that contains 40% alcohol by weight (about 56% by volume) will catch fire if heated to about 26 °C (79 °F) and if an ignition source is applied to it. This is called its flash point. [59]. The flash point of pure ethanol is 16.60 °C (61.88 °F), less than average room temperature. read more

It will form ethene in the presence of conc sulphuric acid. Ethanol will undergo dehydartion. Had the temperature been slightly less, it would have formed an ether. read more
Humans do produce alcohol dehydrogenase (which is actually quite homologous to yeast alcohol dehydrogenase), but it is only in the liver and used to metabolize alcohols from external sources. In fact, one of the effects of ethanol poisoning in humans is the build up of NADH, which causes inhibition of glycolysis through feedback inhibition, and leads to energy starvation. read more
