improved routes to ethylene glycol from:
1. ethylene
2. C, chemistry
improved selectivity in the classical route by
avoidance of:
total oxidation
byproducts
energy costs
new routes based on ethylene by:
1. ethylene acetoxylation, i. e., oxidative
C,H, reaction followed by hydrolysis of
glycol mono- and diacetates and recycling
of AcOH
