Title:
ポリエステルの解重合による大環状エステルの改良製法
Document Type and Number:
Japanese Patent JP2529115
Kind Code:
B2
Abstract:
The catalytic thermal depolymerization of polyesters to produce macrocyclic esters suitable for fragrance applications is carried out using an olefin polymer. High yields of the corresponding macrocyclic ester are produced at high rates while substantially eliminating reactor fouling and the formation of undesirable by-products. The depolymerization is most advantageously conducted using polyethylene.
