In 1995 the world capacity for ethylene glycol was about 9.7 x 106 tonnes per year. Due to its demand and a vast application area lot of research is going on for improving its production statistics. x��=ks�8��S����ҔM��T�'����c�n���Y�-^$R+��z~�u7 ���%�]�"�$�n�� u�r_7�e����˺^,��*��������q�_|\��.��ŋ������ϟ�,�� �E�%�@�$T�r�������6���U���g�>I�Դ�!x�B�:$m�uk��OC�k��֯���O,`2�dpu�Q_�\�y���Y0�Gp�ϟ�����w���)^Uu]mǨ��za�x��8d���L$A�}v5Ogk����dƅ��'�Ei�u�0�z���[�>ۯ�!Ø3����N�} ��s��>^����}�����+������6���YI��c^c�����95��gxI}�mk�Xݶ

Ethylene Glycol is nowadays one of the most industrially important chemical. In the early days of EO production, the typical start-of-cycle selectivity for EO catalysts ranged from 68 to 70%, i.e., 30% or more of the ethylene feed to the process was lost to the complete combustion side reaction. %����
