摘要：

The present work describes the efficient ultrasound-assisted synthesis of saturated aliphatic esters from synthetic aliphatic acids in methanol or in ethanol, using p-toluenesulfonic acid as a catalyst. The esters were isolated in good yields after short reaction times under mild conditions. The compounds were analyzed by high resolution mass spectrometry (HRMS), which give a fragmentations pathway common for these molecules.
