Distillation For Road Tar

Distillation for Road Tar

It is may be defined as the viscous liquid black in color with adhesive properties obtained by destructive distillation of organic matters such as wood,coal,shale etc in the destructive distillation process the material is subjected to heat alone in the absence of air the first step for the production of tar is the carbonization of coal to produce crude tar in the second stage crude tar is refined by distillation process this involves first collection of benzene toluene and xylene and then the middle and heavy oils containing creosote oils and naphthalene the residual material called pitch is then fluxed back with necessary amounts of tar to give the desired road tar.

Features

Gas Heated Model
Electrically Heated with Energy Regulator
Electrically Heated with Varied Control
Tar is a temperature susceptible product resulting in great variation in viscosity with change in temperature
it is not soluble in carbon disulphide and carbon tetra chlohide but is soluble only in toluene
it has a great content of free carbon and is readily distinguished by its typical odour (smell)
Preferred in cement concrete roads as they possess low specific surface area.
Higher workability.
The particle shape is determined by the percentages of flaky and elongated particles contained in it and by determining its angularity.
