A new synthesis of unsymmetrical tertiary phosphines has been developed employing selective, sequential alkylation of chloroaminophosphines by Grignard and organolithium reagents.
The present invention relates to the depolymerization of polymers and the recovery of the starting materials used for the production of the polymer. The present invention also relates to the depolymerization of polyethylene terephthalate (PET) and the recovery of terephthalic acid and ethylene glycol.
