M. MEL'AMID. METHOD OF PRODUCING PUBE TAR DISTILLATES.
APPLICATION FILED JUNE I0| I9I3- Patented Oct. 17,1916,
. UNITED PATENT oFmoE.
V, HEILI-CH' mnnnnrn, or resinous, GERMANY;
0 all whom it may 0 ncern:
Be it known that MErnroH MELAMID, a subject of the Czar of Russia, and residing at Freiburg, in the Grand Duchy of Baden, German Empire, have invented a certain new and useful Method of Producing Pure Tar Distillates, of-which the following is a specification, this applicationbeing in part divided out from-my copendin application for Letters Patent, Serial No. 32,141, filed November 18, 1912.
It has been found that by treating tar, tar oil or other tar derivates with hosphoric acid, products of distillation are 0 tained the in a pure state.
The" Process m y color of which is lighter than that of the products obtained by subjecting said substances to adistillation'of the usual kind.
In spite of all endeavors, when treating tar, no product could be obtained up to now which was ready for use or marketable without being first subjected to a refining or purification rocess. Such products, however. are obtained by means of the present invention, which consists in heating the tar or the tar oil or the other tar derivates together with phosphoric acid and distilling off the products in question which are then obtained be carried out also in thisfl'way that phosphoric acid is heated in the still to such a degree that it is converted into other compounds; this may be ,done
0 either before or after the addition of the tar I cape.
or the like. I i v The mode of execution of the process dependsin sgmemeasure upon the origin of the tar or its products of distillation; one way is the following: 100-150 kilograms of phos-. )heric acid of commerce are mixed with 1,000 'ilo ramsof tar 'or tar oil and this mixture is slibjected to distillation. Or 100 kilograms of technical phosphoric acid are heated in a still'and thereafter 1,000 kilograms of tar or distillates of same or the vapors of same are conducted into' the heated phosphoric acid, from which the purified distillates then es- The distillates obtained by this method have a far lighter color andthey are also far more free. from asphalt than is' the case with the products obtained by the methods hitherto employed.
Other-examples for carrying out my process in practiceare the following: 1,000 k tar or tar oil are well mixed with 50 kg.

process in practice according tothe above examples.- h
A suitable apparatus for carrying out my procex is by way of example illustrated-upon the accompanying sheet of drawing in which 1 is the fire-place, 2 isthe distilling vessel, 3 a thermometer,and 4 a pipe for the removal of the diluted phosphoric acid, 5 is the conduit for the removal of the lighter products I and 6 that for the removal'of the heavier products, while 7 is the water cooled conduit I leading to the receptacle 8 for the products. Thus, for instance, I have succeeded in 0btaining, by my novel process, oils clear'like waterand perfectly white solid hydrocarbons from tars which did not yield up to now p il'gducts of such a kind in one stage only.
's process may be emplo ed for tar, as well as for its distillates and i or all derivates of same, such, for instance, as naphthalene, phenols and anthracene, which may be purified more and more in this way.
In using distillates and derivates of tar, any desired relative proportions may be used,
ivates as for. instance naphthalene, phenols, anthracene are mixed with ,100,kg. phosphoric acid and the mixture. is then heated and distilled. The temperature prevailing 'containedin the tar, consisting in'distilling tar or'tar oils or hydrocarbons contained in the tar with phosphoric acid, substantiallyas described. 4
