For extraction of upper fullerenes and endohedral metallofullerenes (EMF) with yttrium from fullerene-containing carbon soot (soot) obtained by mixed spraying of graphite and yttrium oxide powders in an arc plasma, we developed a tool (Extractor*) that gives mechanical activation results on brokers mixed with filtration. It has been proven that the soot restoration proportion of a combination of upper fullerenes and EMF with completely different solvents (carbon disulfide, o-xylene, pyridine) and the EMF mass fraction within the combination is considerably increased than within the extraction with a Soxhlet equipment historically used for these functions. The time spent on the extraction course of is lowered considerably. As a consequence of a recognized response with titanium chloride (TiCl4) and removing of an answer of empty fullerenes, subsequent bonding of EMF with yttrium into an insoluble advanced straight within the extractor permits the product to be considerably enriched with EMF. Basically, we have been capable of considerably scale back each the period of extraction of the fullerenes combination and EMF and the manufacturing of EMF individually.
A mechanical extractor (Extractor*) developed by us, which permits processing a bigger quantity of carbon black and, accordingly, extracting extra fullerenes per unit of time, has been utilized.
The proportion of extraction from the soot of a combination of upper fullerenes and EMF with varied solvents was considerably increased than with extraction utilizing the Soxhlet equipment.
It has been proven that mechanical extractor utilizing makes it attainable to extend the coefficient of mass switch from the floor of the particles to the extracting brokers.
The Extractor* was first used for the non-HPLC separation of endohedral metallofullerenes with TiCl4. Using the brand new gadget made it attainable to isolate a product considerably enriched in endohedral metallofullerenes.
