文摘
A convenient one-pot-two-step process for chemical recycling of waste PET to produceterephthalohydroxamic acid (TPHA) and terephthalohydrazide (TPHD) was proposed. Decomposition of PET pellets to the corresponding oligomeric mixture in boiling ethylene glycol, followedby its treatment with hydroxylamine and hydrazine at room temperature in 1 h, produced >90%overall yields of TPHA and TPHD, respectively.
