conditions. The increase of the initial H2 pressure from 2 MPa
to 6 MPa enhanced the yields of the main products (1,2-PDO
and EG). The yields of the 1,2-PDO and EG depicted a rapid
growth in the range of 2–4 MPa and mild rise in the other
pressure range, whereas the yields of others-1 and others-2
changed slightly all the time.
