Chemistry & Engineering

Reaction	`C₃H₆ + H₂O → (CH₃)₂CHOH`
Thermodynamics	Exothermic hydration
Catalyst	Acidic ion-exchange resin or zeolite
Reactor class	Trickle bed reactor (mixed phase)
Note	Major route to Acetone via dehydrogenation if Phenol route (Cumene) is not active.

Applications

Cleaning and degreasing solvent
Medical disinfectant
Acetone production (dehydrogenation)
Electronics cleaning

Extraterrestrial Production Pattern

Direct hydration of propylene over acidic catalyst
Sulfuric acid process (indirect) as alternative
Operating at 150-200°C and moderate pressure
Distillation for purification
