Abstract
The present invention provides a process for producing an ester compound, wherein an ester compound is obtained by performing an esterification reaction of a polyhydric alcohol and a fatty acid using any one of a sulfonic acid and a sulfonic acid salt as a catalyst. Thus, it is possible to efficiently produce a multivalent fatty acid ester compound during a short reaction time even in a small amount, because the activity is superior to that of the existing acid catalyst. Further, there is an advantage that the perfluorosulfonic acid catalyst can be easily filtered from the reaction mixture after the esterification reaction, and can be dried and reused.

1 and 2, in the case of Examples 1 to 3 and Examples 11 to 13 using a trifluoromethane sulfonic acid (triflic acid) catalyst, the yield of triester was 80% to 90% after 1 hour of the esterification reaction It can be seen that the reaction is almost completed.
In the case of Examples 4 to 6 and Examples 14 to 16 using a methanesulfonic acid catalyst, the yield of triester was 40% to 50% after 2 hours of the esterification reaction, compared with the PTSA catalyst of Comparative Example 2 and Comparative Example 4 Respectively.
In the case of Example 7 and Example 9 using Nafion NR-50 catalyst, the yield of the triester is 40% to 50% after 1 hour of the esterification reaction but reaches 90% after 8 hours.
In the case of Examples 8, 9, 18, and 19 in which the Nafion NR-50 catalyst was reused once or twice, after 2 hours of the esterification reaction, the yield of triester was close to Examples 7 and 9 And also showed a higher production rate than PTSA catalyst. Therefore, it was found that even when the Nafion NR-50 catalyst was reused, the generation rate of the triester was not significantly different.
In the case of Example 10 and Example 20 using Nafion-Sc catalyst, the formation rate of the triester was about 50% after 2 hours of the esterification reaction, and the production rate was similar to or higher than that of the PTSA catalyst.
On the other hand, in Comparative Examples 1 and 3 in which the catalyst was not used, the triester generation rate did not reach 10% even after 2 hours of reaction, and remained about 30% even after 8 hours had elapsed.
Further, in Comparative Examples 2 and 4 using the PTSA catalyst, the generation rate of triester was about 40% higher than that in the case of not using the catalyst after 2 hours of reaction, but after about 8 hours, the generation rate of triester was about 50% , Indicating a low triester generation rate as compared with the examples of the present invention.
According to the above results, it can be seen that the ester reaction using the sulfonic acid and Nafion catalyst of the present invention is a useful method that can complete the preparation of the ester compound in a very short time as compared with the conventional method and has a high triester generation rate.
