Ethylene glycol diacetate was synthesized from ethylene glycol and acetic acid with ferric chloride hydrate as catalyst. The yield of ester was 92% under the optimum condition.

Plasticizer DOTP was prepared from ethylene glycol residue (major component is PET low polymer) using single step process in which alcoholysis and ester interchange were combined.

A phosphate ester tert-fluorine water dispersion resin(resin monomer total weight% )comprises:1)30.0% ethylene glycol monobutyl ether;
