Ph of ethylene
WebThe highest yields of ethylene glycol occur at acidic or neutral pH with a large excess of water. Under these conditions, ethylene glycol yields of 90% can be achieved. During the process some by-products are formed: Diethylene Glycol (DEG) and Triethylene Glycol (TEG). These by-products are separated from MEG through distillation.
