This procedure has been used successfully for many years in the preparation of ethyl laurate, caprylate, and myristate by the alcoholysis of cocoanut oil (1 kg.) in ethanol (1900 g.) with hydrogen chloride (50 g.) as a catalyst.3 The method differs slightly from the one described above. The alcoholysis is complete after fifteen or twenty hours, and the solution is then neutralized to methyl orange with barium carbonate. The mixture is added to an equal volume of a saturated sodium chloride solution, whereupon 1100-1300 g. of the mixture of crude ethyl esters separates. This mixture of esters is washed with water and fractionated as described above. The yields are approximately 50 g. of ethyl caprylate, 350 g. of ethyl laurate, and 60 g. of ethyl myristate from 1000 g. of cocoanut oil.

From these measurements, the conversion rate was determined from the ratio between ethyl myristate production and myristic acid feed. Then the inital velocity was graphically measured. 

Differences in retention times in the chromatograms are due to the different oven temperature program used. Some remarkable differences in the profiles evidence the different enrichment obtained by the two methods. Data reported in Table 5.2 and Figure 5.3 show evidence of generally good linear correlations between XAD-2 extraction and HS-SPME enrichment methods. In the conditions used for SPME/GC-FID analysis, some compounds such as octanoic and decanoic acids partially overlap ethyl myristate and ethyl palmitate, respectively.
