| 1 | An Efficient and Stable Ionic Liquid System for Synthesis of Ethylene Glycol via Hydrolysis of Ethylene Carbonate显示文摘An ionic liquid system of [Bmim]X/[Bmim]OH(X Cl,BF4,and PF6,) was developed for the hydroly-sis of ethylene carbonate to ethylene glycol. The important parameters,such as the variety of ionic liquids,molar ratio of [Bmim]X to [Bmim]OH,amount of ionic liquid,molar ratio of water to ethylene carbonate,reaction tem-perature,pressure and reaction time,were investigated systematically. Excellent yield(>93%) and high selectivity(99.5%) of ethylene glycol were achieved. Under the optimum reaction conditions,the ionic liquid system could be reused at least five times and the selectivity of ethylene glycol remained higher than 99.5%. | MENG Zhenying SUN Jian WANG Jinquan ZHANG Jianxin FU Zengzeng CHENG Weiguo ZHANG Xiangping | 2010 | Chinese Journal of Chemical Engineering2010，18，6： | 8 |
| 2 | Ocular Symptoms of Tumors at Sella Turcica Region显示文摘Background: The sella tumors were found in 15% of intracranial tumors. The sella turcica region locates in the base of skull, so the carcinoma patients in early stage often showed no intracranial hypertension and other positive signs of neural system. However, the patients presented visual field defect and hypopsia, and often went to see the doctor of ophthalmology, which resulted from that the tumor often compressed optic nerve and chiasm. We analysed the symptomatic changes of the visual organs in order to provide a diagnositic basis for sellar tumor in oph-thalmological department.Clinical materials: Of the 407 cases of sellar tumors, 296 were pituitary adenoma, 52 were craniopharyngioma, 43 were meningioma, and the rest 16 were other kinds of sellar tumors. We analysed their ocular changes of the sellar tumors and the characteristics of the tumors.Results: The sellar tumor in its early stage is mainly symptomized as visual field changes. Visual field defect was found in 92. 9% of pituitary adenoma, | Xiangping Fu, Hongqi WangDepartment of Neuro-ophthalmology, Xijing Hospital The 4th Military Medical University Xian 710032, China | 1996 | Eye Science1996，16，3： | 4 |
