ETHYL NITRITE

ETHYL NITRITE

Ethyl nitrite is prepared by the action of sodium nitrite on a mixture of alcohol and sulphuric acid in the cold. In the laboratory ethyl nitrite gas is conveniently generated by placing 20 litres of 90 percent ethanolin a suitable vessel, diluting with 200 litres of water, and while stirring, adding to the dilute alcoholic nitrosyl chloride.




Ethyl nitrite, b.p. 17°, is a colourless or yellowish, clear, flammable, exceedingly volatile liquid with characteristic pleasant, ethereal odour and burning, sweetish taste. It is slightly soluble in water and decomposed by it; miscible with alcohol and ether. On keeping, it gradually decomposes to an acid and oxides of nitrogen are formed. Decomposition is rapid by air, light, and moisture.



 Uses: Ethyl nitrite is used as diaphoretic and cardiovascular drug. It may cause methemoglobinemia and hypotension and, in high concentrations, narcosis.

HOMATROPINE

HOMATROPINE Brand Names : Mandelyltropeine, Tropine mandelate. Homatropine is a synthetic alkaloid which is a lower homologue of atropine. It is prepared by the interaction of tropine and mandelic acid. Homatropine, m.p. 99-100°, occurs as colourless, odourless crystals or a white crystalline powder. It is hygroscopic, but only slightly soluble in water; soluble in alcohol, benzene, chloroform, ether, acetone and dilute acids. The hydrobromide or hydrochloride is obained readily from the free base by neutralizing with hydrobromic or hydrochkoric acid. The hydrobromide occurs as colourless, odourless crystals or a white crystalline powder. It is soluble in water and alcohol; slightly soluble in chloroform; very slightly soluble in ether; stored in airtight containers and protected from light. Homatropine methylbromide, m.p. 210-212°, is the tropine methylbromide ester of mandelic acid. It is prepared by treating homatropine with methyl bromide, thus yielding the ...
