1,1'-Oxydi-2-propanol Usage And Synthesis

Chemical Properties

Clear liquid

Uses

1,1'-Oxydi-2-propanol is commonly used as a plasticizer, an intermediate in industrial chemical reactions.

Safety Profile

Mildly toxic by ingestion. A skin and eye irritant. Mutation data reported. Combustible when exposed to heat or flame, can react vigorously with oxidizing materials. To fight fire, use alcohol foam, CO2, dry chemical. When heated to decomposition it emits

Synthesis

Dipropylene glycol, propylene glycol, and tripropylene glycol are separated and purified from a crude mixture containing DPG using a three-column continuous vacuum distillation system. The operation involves linked operation of a propylene glycol column (removes PG and catalyst), a dipropylene glycol column (yields DPG product), and a tripropylene glycol column (yields TPG product). Each column controls specific parameters like kettle temperature, top temperature, pressure, vacuum, and reflux ratio for efficient separation.

Purification Methods

Fractionally distil the diol below 15mm pressure, using a packed column and taking precautions to avoid absorption of water. [Beilstein 1 IV 2473.]
