Tris(acetylacetonato)lanthanum(III) (1 mol%) catalyzes the degradation of poly(butylene succinate) (Mw = 90 700) by transesterification in MeOH at 90°C for 4 h, thus affording di-Me succinate (>99% yield) and 1,4-butanediol (98% yield). Moreover, the quant. degradations of poly(ethylene adipate), poly(ethylene terephthalate) and poly(butylene terephthalate) are also reported.
Chemical Communications (Cambridge, United Kingdom) published new progress about 627-93-0. 627-93-0 belongs to esters-buliding-blocks, auxiliary class Ploymers, name is Dimethyl adipate, and the molecular formula is C8H14O4, Formula: C8H14O4.
