Abstract
1. The primary product of condensation of 3-methyl-3-buten-1-ol with formaldehyde is 3-methyl-1,3,5-pentanetriol, while 4-methyl-4-hydroxyethyl-1,3-dioxane is formed as a result of a secondary reaction of acetalization of the triol. 2. The selectivity of the process with at respect to the formation of a triol or dioxane depends on the concentration of formaldehyde and the alkenol, the temperature and duration of the reaction. 3. The kinetic principles established for the reactions studied agree with the carbonium ion mechanism of the process.
