Electron Microscope Goniometry

Abstract

The procedure here described may be employed to advantageIn the determination of methoxyl groups in methyl esters (6).As an example, a sample of dimethyl tartrate was saponified with 4 ml. of 5 N sodium hydroxide. After 3 ml. of distillate had been collected, the latter was diluted and its methanol content de-965 termined by the procedure described. The results showed 2.0 moles of methanol as compared with a theoretical value of 2 moles.
