Goudron

Pyrodialites or Pyrodialytes. A series of expl mixts, patented in Fr by Turpin, beginning in 1881, and contg as principal combustible ingredients, tar (goudron), rosin, etc and as oxidizers, K chlorate alone or in mixt with K or Na nitrates. The following examples are taken from Daniel (Ref 2) Extra forte No 0 K chlorate 88, tar 10, charcoal 5, Na or Amm bicarbonate 2—3ps Lente No 2 K chlorate 40, Na nitrate 48, tar 20, charcoal 5, Na or Amm bicarbonate 4—5ps. These expls were too hot , and were not approved for use in gaseous coal mines... 

Pyrodialytes. Under this term Turpin patented, beginning in 1881, chlorate expls using tar (goudron) as a combustible. In order to neutralize acids present in tar, 2 to 10% of Na carbonate or bicarbonate was incorporated.

The residue remaining after vacuum rectification is called Goudron . This may be used for blending to produce road asphalt or residual fuel oil, or it may be used as a feedstock for thermal cracking or coking units. Vacuum rectification units are an essential part of the many processing units required for the production of lubricants. 

T4 where it is fractionated into oil fraction 11, gases, cracking products and the rest of heavy diesel fraction 14, and vacuum residue or goudron 12. 

Bottom product of vacuum rectification. Often called bitumen or goudron.

HR industrial production began in the United States when in 1920, using as a raw material some coke-chemical fractions, the early products of this category were obtained [315]. In 1927, Neville Cindu Ltd. was one of the largest HR manufacturers [316,317]. Indene-coumaronic resins were marketed in France by HGD (Huiles, Goudrons et Derives) in 1927.
