The same year with the Institute of Fine Chemicalto develop fine chemical products - o-aminobenzoic acid, and 1.4 million yuan of funds into an annual output of 200 tons built anthranilic acid production line, by the province for the Prohibition of Chemical Weapons Convention to fulfill the work of leadership Office approval in April 2002 with an annual output of 200 tons of the scale of operation, product quality compared with similar products in the domestic leading level, in October 2002 to carry out technical transformation again, the scale of production from 200 tons; years expanded to 500 tons; in size, and product performance, production capacity of plant expansion requirements, in 2003 officially put into operation. The end of 2004 our company moved to Sequoia small city are on the 1st, covering over 20,000 square meters, anthranilic acid after the removal of the production line expanded to 1200 tons; in size, at the same time developed a 2,2 - Dithio Benzophenone acid, benzo-iso thiazoline -3 - one, dichloro-acetonitrile, thiophene tons of ketones, a series of inter-amino benzoic acid, etc. Fine Chemical Products.

同年公司与上海桑迪精细化工研究所合作开发精细化工产品—邻氨基苯甲酸，并投入140万元资金建成了年产200吨邻氨基苯甲酸生产线，经省履行禁止化学武器公约工作领导小组办公室批准于2002年4月以年产200吨的规模投入运行，产品质量与国内同类产品相比处于领先水平，2002年10月公司再次进行技改，把生产规模由原来的200吨；年扩到500吨；年规模，且产品性能、生产装置能力达到扩产的要求，2003年正式投入运行。2004年末我公司搬迁至杉城小均1号，占地2万多平方米，搬迁后邻氨基苯甲酸生产线扩大到1200吨；年规模，同时开发了2，2-二硫代二苯甲酸、苯并异噻唑啉-3-酮、二氯乙腈、噻吨酮、间氨基苯甲酸等一系列化工精细产品。

The plots of ln K′ of peptide 1 versus φ are well fitted with quadratic equations when isocratically eluted by aquo _ acetonitrile mobile phases.

当以乙腈为流动相测定肽1的lnK′随φ变化关系时，所得结果显示lnK′与φ呈现良好的二次曲线关系。

The Van't Hoff plots (plots of ln K′ versus 1/T) of the two peptides from microtubule _ associated protein 2 were also determined under isocratic elution conditions with aquo _ acetonitrile mobile phases.

以乙腈为流动相测定肽1和肽2的Van'tHoff曲线(lnK′与1/T的关系图)时，发现两种多肽的Van'tHoff曲线分别呈二次和三次方曲线。

Computationalresults indicate that the no-planar trans-benzanilide is the most stable structure. The spectra indicate that the Franck Condon region photodissociation dynamics have multidimensional character withnine activemodes. The intensity of υ24 mode in methanol is much stronger than that in acetonitrile. Compared with fatty amides and benzamide, phenyl substitution for H atom on-NH2 group makes C=O solvent effects disappear.

结果表明，苯甲酰苯胺的非平面反式结构为最稳定结构；在Frank-Condon区域内，苯甲酰苯胺主要由9个活性振动模组成；其中ν24（苯环上C＝C不对称伸缩振动和CCH的面内弯曲振动，NH面内弯曲振动）振动模在甲醇溶剂中的强度远远大于其在乙腈的强度；与脂肪酰胺类化合物和苯甲酰胺的研究结果比较发现，苯基取代－NH2上的H原子使得C＝O不再具有明显的溶剂效应。
