FIELD: layered silicate catalysts; synthesis of polyethylene terephthalate.
SUBSTANCE: invention relates to a method for producing layered silicate catalysts intended for the synthesis of polyethylene terephthalate. A layered silicate catalyst for the synthesis of polyethylene terephthalate is proposed based on a solution of montmorillonite and tetraisopropoxytitanium, the content of which is 30 wt.% by weight of the clay, and montmorillonite is pre-dispersed for 60 minutes in distilled water at a ratio of 1:2, followed by the addition of ethylene glycol. The ratio of the clay solution to ethylene glycol is 1:6.
EFFECT: production of an effective, environmentally friendly catalyst for the synthesis of polyethylene terephthalate.
