Synthesis of ε-caprolactone

1. Background

ε-caprolactone monomer is a useful chemical intermediate and can also be used as a strong solvent. Polycaprolactone (PCL) is widely used in the synthesis of environmentally friendly materials (degradable plastics).

2. Process

Dimethyl adipate (DMA) was firstly prepared by continuous esterification from adipate (AA) and then hydrogenated to 1, 6-hexanediol (HDO). ε-caprolactone is a by-product. Because of its high value, we can get high value-added by-products by distillation separation.
