Over the past years, many innovative processes for producing synthetic fiber monomer have been developed. These have been broadly divided into three levels:(1)optimizing, reducing leakage, drops and spills;(2)changing the reactor or reaction conditions and introducing new catalysts; and(3)completely changing raw materials, such as the replacement of aromatics with butadiene, biomass and other non-aromatic raw materials. Renewing most of the first two levels can achieve energy saving, consumption reducing, and production cost lowering. Although the 3rd level was an attempt to tackle the problem at the source and can be considered as completed greening progress, industrialization is more difficult than for the 1st and 2nd levels, perhaps due to material consumption and energy consumption. It is harder for it to be compared favorably with traditional aromatic raw material route and the introduction of new hazardous materials or too many by-products. In order to advance the process of green chemical fiber monomer production, find new ones, and build new road as soon as possible, this paper reviews the green process achieved by our predecessors in order to further the use of patented data with analysis tools, track the frontrunner footprint in green progress of raw materials preparation, process improvement, and three waste treatment. Furthermore, it is recommended that atomic and mass efficiency and life cycle inventory(LCI)be introduced first before completing life cycle assessment(LCA)of greenhouse gas emissions as indicators in the measurement and comparison of the green progress and innovative improvement, in order to make objective and practical evaluation and avoid biased or misled viewpoints produced when inconsistent border(range)was chosen in comparison. In the future, the multiple evaluation systems such as eco-efficiency and SEEBALANCE will be introduced as indicators in green chemistry or green engineering.
