Artifacts produced during acid-catalyzed methanolysis of sterol esters
JK Kramer and HW Hulan
Sterol esters were transesterified within 1 hr using either acid or base
catalysts. Acid-catalyzed methanolysis of sterol esters with HCl, H2SO4, or
BF3 leads to the formation of two artifacts derived from the sterol portion
of the molecule; they were identified as dehydrated and methoxylated
derivatives of sterols. These two artifacts were not produced using a
base-catalyzed methanolysis with NaOCH3.
