Latest advances in preparation of ethylene glycol(EG) were reviewed, including preparation of EG via catalytic hydration from ethylene oxide(EO) and ethylene carbonate(EC), as well as via syngas.

Four preparation methods for aromatic amine were reviewed in the paper: reduction of metals, catalytic hydrogenation reduction, hydration hydrazine reduction and electro-chemical reduction.

The preparation method of the catalyst prepared by anodic oxidation of aluminium, hydration treatment and impregnation of the catalytic active substance is introduced in this paper.
