WebCAS: 7647-01-0 MDL: MFCD00011324 Methanolic HCl (hydrogen chloride in methanol) is particularly useful for preparing methyl esters of volatile (short chain) fatty acids. Fatty acids are esterified by heating them with an anhydrous alcohol in the presence of an acidic catalyst in a sealed vessel at a high temperature for a short time. In the reaction, a fatty … WebThe solution started to fizz rapidly, and then it slowed down after about 10 minutes as more NaBH4 was added. Next, when the previously created solution was heated over a steam bath, it boiled vigorously. Later, during the addition of 6M HCl, after enough HCl was added, the litmus paper turned bluish black when the solution was dropped on it.
