Reaktionsschritte

A) Route without additives: In a test tube the mixture of 1 ml (2.95 mmol) of methyl oleate, the corresponding amount of 2-butene-1,4-diol (0.24 ml or 0.73 ml) and 0.1 ml of tetradecane (internal standard) is prepared and mixed. If the reaction is being carried out without solvent, a blank sample is taken for GC measurement. In the case of the procedure with solvent, a blank sample for GC measurement is taken only after the addition of 1 ml of the corresponding solvents. After sampling has taken place, the reaction vessel is placed in the thermally conditioned oil bath. The mixture is stirred for about 2 minutes using a magnetic stirrer. When the desired temperature of the mixture has been reached, the catalyst (2 mol %) is added. The reaction mixture is further heated and stirred, and after 4 and 24 hours of reaction the next GC samples are taken for kinetic determinations. After 24 hours the reaction is halted by addition of 1 ml of ethyl vinyl ether.
