Abstract

An analytical method for quantitative determination of fatty ester of 3-phenylamine-1,2-propanediol has been developed. The procedure is based on the spectrophotometric determination of coloured compounds formed by reaction of acylderivatives with p-DMACA. Monoacylderlvative is quantified at 500 nm and diacylderivative at 510 nm, with range of ±0,031 and ±0,020 absorbance units, respectively. The essential application of this method is to obtain the yield of synthesis reaction of acylderivatives of 3-phenylamine- 1,2-propanediol. However, an isolation of every one products by thin layer chromatography is necessary before analytical technical application. Moreover, this procedure supply a way for analysis of similar structure compounds.
