What is the main cause of the formation of dodecanamides instead of methyl esters?

05 January 2023 1 3K Report

Hello all,

We have perfomed a methylation either by using KOH-methanol transesterification or by using BF3 as catalyst , after injection using GC MS of the hexanoic phase we have fatty acids peaks just at the appearance but when integrating them they are apparently identified as dodecanamides!

Can you please help us to find out what might be the cause of this result knowing that this the first time with this failure!

regards

Aouatif Benali

Many thanks for your response.

we will try to change all the used reagents and re inject the sample.
