Description

Verfahren zur Herstellung heller, an der Luft leicht trocknender Öle aus den Säureharzen der 13enzolfabrikation. Die bei der Herstellung von Benzol sich ergebenden Rückstände, die sogenannten Säureharze, waren bisher wertlos. Versuche, sie durch. Destillation zu verwerten, schlugen fehl, da sich keine brauchbaren Öle ergaben, und es wurden daher diese Rückstände nach wie vor in großen Mengen auf die Halde geivorfen. Nach der Erfindung können aus den Säureharzen hochwertige, als Handelsprodukt gut verwertbare Öle dadurch gewonnen werden, daß die Harze der Vakuumdestillation unterworfen werden. Es hat sich gezeigt, daß bei der Destillation unter Druckverminderung helle, an der Luft leicht. trocknende Öle erzeugt werden und dag sich dabei eine verhältnismäßig hohe Ausbeutung ergibt. Die in den Harzen enthaltenen Sulfosäuren liefern bei der Destillation schweflige Säure, die in bekannter Weise zu Schwefelsäure verarbeitet wird.Process for the production of light-colored oils that dry easily in the air from the acid resins of 13enzene production. Those involved in the manufacture of benzene themselves The resulting residues, the so-called acid resins, were previously worthless. Try, them through. Utilizing distillation failed because there were no usable oils and therefore these residues continued to arise in large quantities thrown the heap. According to the invention, high-quality, As a commercial product readily usable oils are obtained that the resins of the Be subjected to vacuum distillation. It has been found that during the distillation light under pressure, light in the air. drying oils are produced and that there is a relatively high level of exploitation. The ones in the resins The sulphonic acids contained in the distillation process produce sulphurous acid, which is known in Way is processed into sulfuric acid.
