Paper Chromatography.—Solvent systems have been developed for the separation of trichloromethyl- phenyl-, and pentafiuorophenyl-phosphonic and -phosphinic acids. Phosphoramidates and their hydrolysis products have been chromatographed, using triethylamine as a buffer. Silica gel on glass-fibre sheets may be used to separate inositol from its phosphate and to analyse phosphatide glyceryl ethers. ...
