Abstract
Two techniques for the separation of acids eaters was tested. A simple quan titative reaction which converts all acids to the sylyl methyl esters is de scribed These derivates can be separated and quantitated by gas chromatogra phy using a capillary column packing with SE52 and internal standard methyl palmitate. The total time for esterification and analysis time: is of one hour The qualitative determination analysis of acids end esters was accompl ished by thin layer chromatography in the following conditions fluorescent kieselgel and eluents system (isooctan:acetate isoamyl) was used. The ident ification method was the colons reaction with a solution of bromcresol gree n and fluorescence exposure.
