Conclusions
-
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.
