METHOD OF PRODUCING CATALYST FOR POLYMERISATION OF LACTONES OR POLYCONDENSATION OF ALPHA-OXYACIDS |
摘要 |
FIELD: chemistry.SUBSTANCE: disclosed is a method of producing a catalyst by reacting tin metal with oxyacids, wherein catalyst synthesis is carried out in a melt or solution of oxyacids in the presence of oxidising agents at temperature of 20-240°C while stirring constantly. The oxidising agents used are air or molecular oxygen or hydrogen peroxide or organic hydroperoxides. The ?-oxyacids used are compounds with ratio of hydroxyl to carboxyl groups in the range of 1(3):3(1). Condensation of oxyacids with removal of the released water can be carried out concurrently or consecutively with catalyst synthesis.EFFECT: simple process of producing a catalyst which is compatible with the next catalysis objects, is protected from hydrolysis and does not require solvent for dosage.4 cl, 1 tbl, 11 ex |
