- Derivatives of Pentaerythritol, V. - Synthesis of Dimethylolacetic Acid
-
Starting from pentaerythritol (4), 3-hydroxy-2-(hydroxymethyl)propanoic acid (3) was prepared in pure state via the intermediates 5,5-bis(hydroxymethyl)-1,3-dioxane (5), 1,3-dioxane-5,5-dicarboxylic acid (6), and 1,3-dioxane-5-carboxylic acid (7).

- Derivatives of Pentaerythritol, IV. - Identification of By-products in Pentaerythritol Process Liquors
-
Several previously unknown by-products of the pentaerythritol synthesis were identified by comparison of their GC/MS spectra with the spectra of pure compounds.Furthermore, pure 2-hydroxymethyl-2-(methoxymethoxymethyl)-1,3-propandiol (5) was isolated from mother liquors, and the reference compounds 5-hydroxymethyl-1,3-dioxane-5-carboxylic acid (6) and 3--2,2-bis(hydroxymethyl)propanoic acid (7) were synthesized.
