Alcohols, burning

ETHYL ALCOHOL, [CAS 64-17-5] C H,OH. formula weight 46.07. is a colorless liquid with mild characteristic odor, rnp -114 ] C, bp 78.32 C. sp gr 0.789. Also known as ethanol, the compound is miscible in all proportions with H 0 or ether. When ignited, ethyl alcohol burns in air with a pale blue, transparent flame, producing H 0 and CO . The vapor forms an explosive mixture with air and it is used in some internal cumbustiim engines under compression as a fuel. See also Fuel. Such mixtures are frequently referred lo as gasnhol. 

The substitution of one hydroxyl radical for a hydrogen atom in propane produces propyl alcohol, or propanol, which has several uses. Its molecular formula is CjH7OH. Propyl alcohol has a flash point of 77°F and, like all the alcohols, burns with a pale blue flame. More commonly known is the isomer of propyl alcohol, isopropyl alcohol. Since it is an isomer, it has the same molecular formula as propyl alcohol but a different structural formula. Isopropyl alcohol has a flash point of 53°F. Its ignition temperature is 850°F, while propyl alcohol s ignition temperature is 700°F, another effect of the different structure. Isopropyl alcohol, or 2-propanol (its proper name) is used in the manufacture of many different chemicals, but is best known as rubbing alcohol.

Neither the handkerchief nor the banknote have suffered any damage, because only the alcohol burns. The flame has the characteristic yellow color of sodium. The boiling point of ethanol is 78 C, while its flash point is 12 °C.

Formaldehyde is produced abundantly when methyl alcohol burns in an amount of air which is insufficient for its complete combustion. Special forms of lamps have been devised in which methyl alcohol is burned under these conditions. They are used for disinfecting purposes.

We have seen that hydrocarbons undergo combustion in the presence of oxygen. Alcohols burn with oxygen, too. For example, in a restaurant, a dessert may be prepared by pouring a liquor on fruit or ice cream and lighting it. The balanced equation for the combustion of the ethanol in the liquor proceeds as follows ... 

A disease which causes the noninflammatory degeneration of many of the peripheral nerves. It may result from (1) certain deficiency diseases, (2) metabolic diseases, (3) chemical poisoning, (4) some infective diseases, (5) a carcinoma, or (6) some rare genetic diseases. Symptoms consist of cramps, numbness, weakness, loss of reflexes, loss of positional senses, and partial paralysis. Usually the legs are affected first, and then the arms. Those deficiency diseases exhibiting polyneuropathy are beriberi, pellagra, chronic alcoholism, burning feet syndrome, and pyridoxine or pantothenic acid deficiency.
