FIELD: chemistry.SUBSTANCE: one of the method versions includes: bringing a hydrocarbon flow in contact with, at least, one sorbent, which adsorbs, at least, a part of admixtures from the hydrocarbon flow with obtaining a purified hydrocarbon flow; after that, separation of the purified hydrocarbon flow from, at least, one sorbent; then, preliminary processing of, at least, one sorbent before the stage of contact, where the stage of preliminary processing represents manufacturing a sorbent, capable of adsorbing admixtures; where the stage of preliminary preparation includes: a) washing the sorbent with a solvent, b) regulation of pH of the sorbent, present in the solvent to pH higher than 10, c) deaeration of the sorbent, present in the solvent, d) removal of the solvent from the sorbent and e) the sorbent drying. The sorbent represents clay.EFFECT: application of the claimed invention makes it possible to obtain monomers with an increased stability, prevent the contamination of processing systems and provide more complete reproducibility of polymerisation reactions.17 cl, 2 ex, 4 tbl, 1 dwg |
