Production of ethylene glycol

Production of ethylene glycol

The principal by-products are diethylene glycol and higher glycols (e.g. triethylene glycol). The formation of these higher glycols is inevitable as ethylene oxides react more rapidly with ethylene glycols as with water.

Systems maintain a high conversion rate by using excess amounts of water to promote ethylene glycol production selectively.

The excess water is removed by a series of evaporators and recycled. The ethylene glycol is then refined by vacuum distillation.
