Cocaine is a weakly alkaline compound (an  alkaloid ), and can therefore combine with acidic compounds to form various salts. The hydrochloride (HCl) salt of cocaine is by far the most commonly encountered, although the sulfate (-SO 4) and the nitrate (-NO 3) are occasionally seen.t is commonly snorted, inhaled, or injected into the veins. Mental effects may include loss of contact with reality, an intense feeling of happiness, or agitation. Physical symptoms may include a fast heart rate, sweating, and large pupils.
The leaves are moistened with lime water or other alkali and extracted with kerosene (paraffin). The dissolved cocaine is extracted from the kerosene with sulfuric acid to produce an aqueous solution of cocaine sulfate. This solution is neutralised with lime, causing cocaine base (coca paste) to precipitate.ocaine is the methyl ester of benzoylecgonine and is also known as 3Î²-hydroxy-1Î±H,5Î±-H-tropane-2Î²-carboxylic acid methyl ester benzoate. Although four pairs of enantiomers are theoretically possible, only one (commonly termed l-cocaine) occurs naturally.
