Vapor–Liquid Equilibria and Chemical Equilibria in the System (Formaldehyde + Water + Isoprenol)

Isoprenol (3-methyl-3-buten-1-ol) is an important intermediate in the chemical industry and used, for example, production of various scent flavor chemicals. produced from aqueous formaldehyde isobutene separated by distillation mixtures containing formaldehyde, water, process. As forms oligomers with both water isoprenol, these are complex reacting systems, which not easy to separate. Hence, understanding modeling process, information on vapor–liquid equilibria system (formaldehyde + isoprenol) essential. However, only very limited data this available literature. Therefore, present work, were measured following systems: (water at 20 90 kPa, 373 393 K, K. Furthermore, oligomerization reactions isoprenol studied 13C-NMR spectroscopy temperatures ranging 283 353 The experimental used extend a physico-chemical model water) literature include isoprenol.
