Advanced purification and comprehensive utilization of yellow phosphorous off gas

Ping NING,Xiangyu WANG

Frontiers of Environmental Science & Engineering 2015, Volume 9, Issue 2, Pages 181-189 doi: 10.1007/s11783-014-0698-1

Abstract: Yellow phosphorous is an important raw material in the chemical industry. However, during the production of yellow phosphorous, high concentrations of carbon monoxide and other impurities are released. Without appropriate purification and removal, this off gas has potential to cause severe pollution problems once released. Purified yellow phosphorous off gas can be beneficially reused as a raw material in chemical production for synthesis of high value-added chemical reagents. In this paper, the significance of purification and reutilization of yellow phosphorous off gas are explored. The principles, processes, and main characteristics of the technologies for purification and reuse of yellow phosphorus off gas (including technical measurements of impurity reduction, relevant engineering cases, and public acceptance of the technologies) are summarized. In view of the existing problems and scientific development requirements, this paper proposes several recommendations for green production based on the concept of recycle economics. We conclude that advanced purification and comprehensive reutilization can be an effective solution for heavy pollution resulting from yellow phosphorous off gassing.

Methodologies for chemical utilization of CO

Liangnian HE, Ya Du, Chengxia MIAO, Jinquan WANG, Xiaoyong DOU, Ying WU

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 2, Pages 224-228 doi: 10.1007/s11705-009-0067-y

Abstract: The reactions of CO with oxirane to produce cyclic carbonate, and with aziridine to afford oxazolidine have been of interest as a useful method for its fixation by a chemical process. Highly efficient processesemploying recyclable CO -phlilic homogeneous catalyst were devised for environmentally benign synthesis of cyclic carbonates and oxazolidinones under supercritical CO without any organic solvent. These processes represent pathways for greener chemical fixations of CO to afford industrial useful materials such as organic carbonates and oxazolidinones with great potential applications.
