Propene resembles other alkenes in that it undergoes addition reactions relatively easily at room temperature. The relative weakness of its double bond explains its tendency to react with substances that can achieve this transformation. Alkene reactions include: 1) polymerization, 2) oxidation, 3) halogenation and hydrohalogenation, 4) alkylation, 5) hydration, 6) oligomerization, … WebBoiling Point Chart Boiling Point of Propylene Glycol/Water Mixtures 200 190 180 170 160 150 140 130 120 110 100 0 10 20 30 40 50 60 70 80 90 100 % PG in Water Source: Glycols.
