Issue 4, 2016 - China's first organic guanidine-catalyzed polycondensation PLA process

China's first organic guanidine catalyzed polycondensation PLA process
Recently, the pilot and application project of organic guanidine catalytic condensation into polyL-lactic acid technology led by Nanjing University passed the expert appraisal
in Lanzhou.
The appraisal committee, composed of 9 experts, including Academician Ouyang Pingkai, Academician Qian Yi, Academician Cai Daoji, Academician Jiang Shicheng and Academician Chen Fahu, believes that this technology is the first green synthesis process developed at home and abroad, which is original and reaches the international leading level
.

Appraisal experts believe that the non-toxic, metabolizable and green organic guanidine catalyst used in this process is the first at home and abroad, which has the characteristics of strong specificity of catalytic lactic acid polycondensation structure, small dosage and high catalytic efficiency.
The solvent-free polymerization adopted is a green synthesis process, with high reaction yield and low production cost; Pilot polylactic acid (PLA) has high product quality, good biological and environmental safety, strong heat resistance, and comprehensive performance leading in China and advanced
in the world.
