Abstract: Various carbonyl reagents and catalysts employed in the synthesis of dialkyl hexamethylene-1,6-diyldicarbamate (HDC) were reviewed. The advantages and disadvantages of carbonyl reagents such as CO，CO2，dimethyl carbonate (DMC) and alkyl carbamate in the synthesis of HDC were analyzed systematically. The low toxicity，high activity and wide raw material sources make alkyl carbamate the most industrialized carbonyl reagent for HDC synthesis. The catalysts for the preparation of HDC from dimethyl carbonate and alkyl carbamate were introduced，classified，reviewed and summarized in the aim of providing a guide for the development of efficient catalyst for HDC synthesis. Preparation of cheap，easy recovered and recyclable environmentally friendly catalyst would be the key to promote the industrialization of HDC synthesis.
