FIELD: chemistry.
SUBSTANCE: invention relates to a solid composition for producing polyethylene terephthalate, a method of producing said composition and use of the composition in polymerisation of BHET into polyethylene terephthalate. Disclosed composition contains at least 90.0 wt.% of bis(2-hydroxyethyl)terephthalate (BHET) in terms of dry weight and has pore volume in range of 0.20–1.0 cm3/g.
EFFECT: obtaining an alternative solid form of BHET of high quality.
