Determination of fatty alcohols in fatty alcohol sulfates
A simplified procedure for the quantitative determination of very small amts of fatty alcohols in fatty alcohol sulfates has been developed. In the present work this procedure was applied to the determination of lauryl alcohol in lauryl alcohol sulfate.
OBJECTIVE ::: To establish a new method to discriminate Aaron's beard by Fourier transformation infrared spectrometry. ::: ::: ::: METHODS ::: Attenuation Reflection-Fourier transformation infrared spectrometry with clustering analysis was used to the identification of Aaron's beard. ::: ::: ::: RESULTS ::: There were obvious differences in Aaron's beard. The results are consistent with that of morphologic study. ::: ::: ::: CONCLUSION ::: This method is rapid, simple and economical, and can be used to the quality control.
