宋纪蓉教授现为西北大学教授、博士生导师、化工学院院长、中国民主同盟中央委员。陕西省政协委员,西安市人大常委。同时兼任中国化学会化学热力学和热分析专业委员会副主任,中国化工学会生物化工专业委员会委员,陕西省化工学会副理事长。她近年来从事精细化工和生物化工的研究和教学工作,现已出版著作三部,获陕西省科技进步一等奖、陕西省科学技术奖二等奖等省部级奖六项。在《Thermochimica Acta》、《Journal of Molecule Structure (THEOCHEM)》、《Journal of Thermal Analysis and Calorimetry》、《中国科学(B 辑)》《科学通报》、《化学学报》、《Journal of Chinese Chemistry》和《高等学校化学学报》等国内外著名期刊上公开发表论文60 余篇,且20 余篇被SCI、EI 等国际著名索引收录。近年来获得国家自然科学基金、高等学校骨干教师资助计划项目、科技部国家级星火计划项目、中国博士后基金、陕西省自然科学基金、陕西省重点攻关项目等多项资助,有8 项研究成果通过省级技术鉴定。
近年来,主要从事以下两个方面的科学研究工作,并做出了突出的贡献:(1)NTO 类功能材料的研究 3-硝基-1,2,4-三唑-5-酮(NTO)类新材料的合成、性能、热分解机理及应用研究是近年来国内外研究的热点之一。她系统地研究了NTO 金属盐类的合成、晶体结构、热分解机理、热力学性质及应用。从微观上获得了这类功能材料的组成原子或离子的空间排列、化学结合方式、分子的主体构型、构象、电荷分布、热振动情况以及精确的键长、键角等数据,开创了NTO 类功能材料的微观系统研究,得到了国内外同行的高度评价。(2)苹果资源综合深加工研究陕西是全国最大的苹果生产基地之一,随着苹果种植业的蓬勃发展,作为鲜果食用的苹果出现了饱和。1994 年以来,在陕西先后建成了二十多条苹果榨汁生产线。由于国际市场的变化,苹果浓缩汁价格急剧下跌,因此延长苹果加工产业链、提高深加工产品的附加值迫在眉睫。宋纪蓉教授的研究采用高科技生物工程技术,发酵生产出系列苹果酒和苹果白兰地;同时利用苹果榨汁线上排出的苹果渣生产膳食纤维、柠檬酸、饲料蛋白和生物有机肥。

[Li(NTO)(H2O)2] was prepared by mixing the aqueous solution of 3-nitro-1, 2, 4-triazol-5-one (NTO) and lithium hydroxide. The crystal structure of [Li(NTO)(H2O)2] was determined by single crystal diffraction analysis. The crystal is monoclinic, space group P21/n with crystal parameters of α=0.742 0(2)nm, b=0.344 9(1)nm, c=2.490 6(3)nm, β=94.89(1)α, Z=4, Dc=1.799g. cm 3, V=0.635nm3, μ=l.591cm-1, F(000)=392. The finaIR is 0.051. TheMNDOMOcalculation shows that the coordinate bonds of title compound possess certain extent of covalent character. 02 atom of NTO anion is bonded to Li atom; the nitro group will be lost first when NTO is decomposed.

The single crystal of lead salt of 3-nitro- 1, 2, 4-triazol-5-one (NTO), [Pb(NTO)2.H20] was prepared and its structure was determined by a four-circle X-ray diffractometer. The crystal is monoclinic, its space group is P21/n with crystal parameters of a=0.7262(1) rim, b=1.2129(2)nm, c=1.2268(3)nm, [3=90.38(2)o, V=1.0806(2)nm3, Z=4, Dc=2.97gcm-3, p.=157.83cm-1, F(000)=888. The final R is 0.027. By using SCF-PM3-MO method we obtained optimized geometry for [Pb(NTO)2.H20] and particularly positions for hydrogen atoms. Through the analyses of MO levels and bond orders it is found that Pb atom bond to ligands mainly with its 6p, and 6py AOs. The thermal decomposition experiments are elucidated when [Pb(NTO)z.H20] is heated, ligand water is dissociated first and NO2 group has priority of leaving. Based on the thermal analysis, the thermal decomposition mechanism of [Pb(NTO)2.H20] has been derived. The lattice enthalpy and its lattice energy were also estimated.

Cellulase can evidently incerase th content of glucose and has a singiflicant effect on the production of citric acid from apple pomace by Aspergillus niger. Based on experiments, a cellulolytic enzyme named cellulase A6 was found able to produce about 170g glucose from 1kg dried apple pomace after 12h reaction, with cellulase comcentration of 20U/g the medium at 50℃, natural pH without pretreatment of alkali. Using the treated apple pomace as a liquid apple pomace at 35℃ in 3d or 30℃ in 5d with flask rotation speed of 210r/min, and the conversion of citric acid could reach 80% based on the amount of sugar consumed.
