Preparation and Characterization of Phosphorus Pentafluoride Gas for Lithium Ion Battery Electrolyte Salt

引用

Chemical Research in Chinese Universities 2009年第6期25卷 791-795页

作者： LIU Jian-wen LI Xin-hai WANG Zhi-xing GUO hua-jun HU Qi-yang School of Metallurgical Science and Engineering Central South University Changsha 410083 P. R. China

A novel preparation method of phosphorus pentafluoride（PF5） is introduced in details in the article. Phosphorus pentafluoride is mainly used to synthesize lithium ion battery electrolyte salt. In the experiment mesneproduct- hexafluorophosphoric acid（HPF6） was firstly prepared-from phosphorus pentoxide（P2O5） and anhydrous hydrogen fluoride（HF）, according to the chemical stoichiometrics, the optimum amount of excess HF used was about 60% and the optimum reaction time was 4 h; then HPF6 was dehydrated by oleum with an excess amount of 35%-- 40% which was heated for 40--50 min at 150 ℃; thus HPF6 was decomposed to a mixture of gases containing PF5; impurity gases were removed through condensation in the presence of cooling water at 0 ℃, then PF5 of high purity was eventually prepared. The production was characterized by inffared（IR） spectrometry and gas chromatography-mass spectroscopy-selected ion monitoring（GC-MS-SIM）. Eventual results indicate that PF5 prepared by the novel method has a high target purity and a low amount of impurity and water.

Evaluation of regional bulbar redness using an imagebased objective method

引用

International Journal of Ophthalmology(English edition) 2014年第1期7卷 71-76页

作者： Wen-Juan Zhao Fang Duan Zhong-Ting Li hua-jun yang Qiang huang Kai-Li Wu Zhongshan Ophthalmic Center State Key Laboratory of OphthalmologySun Yat-sen University

AIM: To develop an image-based objective method to precisely evaluate regional ocular bulbar injection. · METHODS: Six healthy adult volunteers were photographed in four orientations(superior,inferior,nasal and temporal sides) with and without stimulating eye drops. Six line segments(covering 30°) were drawn 4mm away from the limbus on each image using ImageJ software. The graph peaks,which were derived from the areas under the line segments and corresponded to the cross-sectional grey-level of the vessels,were analyzed to obtain peak area,peak height/width(PH/PW),and peak numbers. Different-sized areas were selected to calculate the pixels based on the edge-detection algorithm. Also,conjunctival and superficial scleral vessels were analyzed separately. ·RESULTS: This method had a smaller coefficient of variation,especially for PH/PW,in all four orientations. Hyperaemia parameters changed the least after challenging in the superior region. Moreover,95% of the PH/PW ratios were greater than 0.87 in conjunctival vessels and less than 1.00 in superficial scleral vessels. PH/PW significantly increased in conjunctival vessels and changed less in superficial scleral vessels. ·CONCLUSION: A new method of objectively assessing bulbar injection based on ocular surface images was developed. This method can be used to quantify ocular regional injection and to distinguish the superficial scleral and conjunctival vessels.
