The Dibutyl phthalate is recovered and purified by use of vacuum distillation or through a bed of activated charcoal.
Applications
Dibutyl phthalate is often added to polyvinyl chloride as a plasticizer in order to improve it material characteristics. Dibutyl phthalate does not polymerize when added to PVC and allows for PVC molecules to slide along one another without tangling. The ability to avoid the polymers from becoming entangled will increase the flexibility of the PVC, making it more suitable for a number of applications. Vinyl fabrics and raincoats are examples of how Dibutyl phthalate will increase the flexibility of PVC.
Dibutyl phthalate is entirely composed of carbon, oxygen and hydrogen making it ideal for combustion reactions. Dibutyl phthalate is used as a stabilizer within solid rocket propellant as Dibutyl phthalate readily contributes molecules to sustain the combustion reaction at elevated temperatures.
