利用GPC测定标准样品的异氰脲酸酯含量，结合ATR谱图中异氰脲酸酯吸收峰的强度得到外标工作曲线，以此为基础利用FTIR-ATR技术测定聚异氰脲酸酯泡沫中异氰脲酸酯三聚体含量。

Isocyanurate based on TDI was synthesized and the heat-resistance property of casting polyurethane elastomer which synthesized using isocyanurate based on TDI and PEPA was obviously enhanced compared to polyurethane elastomer which did not introduce the isocyanurate by the TGA under the different temperature and the mechanics performance maintenance rate at high temperature.

在催化剂作用下，合成了TDI-100型异氰脲酸酯，并与己二酸乙二醇丙二醇酯合成了浇注型聚氨酯弹性体，通过不同温度下的热失重分析和弹性体的力学性能高温保持率对比分析表明，在TDI型聚氨酯弹性体中引入异氰脲酸酯基团，可明显提高弹性体的耐热性能。

In this study, we investigate the effect of benzyl isothiocyanate and phenethyl isothiocyanate on human prostate cancer DU-145 cells, the results demonstrate that benzyl isothiocyanate and phenethyl isothiocyanate induced cause G2 / M phase arrest and apoptosis. These effects are in a dose- and time-dependent manners.

但是苯甲基异硫氰酸酯和苯乙基异硫氰酸酯造成人类前列腺癌细胞株DU-145的凋亡机转则尚未有较详细的报导，所以本研究即是探讨苯甲基异硫氰酸酯和苯乙基异硫氰酸酯造成人类前列腺癌细胞株DU-145的相关凋亡机转。

The volatile components were separated and identified using GC-MS technique. RESULTS Seven ingredients were. isolated: 2-ethyl-hexyl-adipate (66.5%), 1-methoxy-4-(1-propenyl)benzene (12.5%), isopropyl isothiocyanate (6%), isobutylisothiocyanate (6%), 6-methyl-5-heptene-2-one (3.5%), benzaldehyde (1.4%), phenylacetaldehyde (0.8%).

结果 分离出7个成分，采用峰面积归一化法确定了各成分的相对含量，分别为66.5%双－2-乙基己基－己二酸、12.5%1-甲氧基－4-（1-丙烯基）苯、6%异硫氰酸异丙酯6%、6%异硫氰酸异丁酯、3.5%6-甲基－5-庚烯－2-酮、1.4%苯甲醛、0.8%苯乙醛。

Firstly, headspace solid-phase microextraction was established to determine AITC by orthogonal design. Extraction temperature, stir speed, extraction time, and desorption time were set at 40℃, 900r/min, 30min, and 5min, respectively. Under these optimal conditions, volatile flavor compounds in mustard oil, wasabi, and 'Chongcai'leaf mustard product were identified by SPME/GC/MS. In these three samples, 6,12,17 constituents were identified respectively; Allyl isothiocyanate was the main flavor compound, which accounted for 73.45%, 64.25%, 32.74% of total volatile compounds, respectively. Carbon disulfide, a hydrolysis product of AITC, accounted for 14.37% 25.40%, 51.67% of total volatile compounds respectively. There were some other isothiocycannates, such as butane, 1-isothiocyanato-, isobutyl isothiocyanate, 1-benzene, 4-isothiocyanato-, benzene (2-isothiocyanatoethyl)-, etc.

首先采用正交实验设计优化固相微萃取技术的前处理条件，结果表明，以萃取温度40℃、搅拌速度900r／min、萃取时间30min、解吸时间5min为最佳条件；在此最优条件基础上，利用SPME／GC／MS联用技术分析芥末油、青芥辣、冲菜的挥发性风味成分，分别检出6、12、17种化合物，主要风味物质均为AITC，相对丰度分别为73.45％、64.25％、32.74％；AITC的水解产物二硫化碳的相对丰度分别为14.37％、25.40％、51.67％；还检测到了其它几种异硫氰酸酯，如异硫氰酸丁酯、异硫氰酸异丁酯、异硫氰酸丁烯酯、2-苯乙基异硫氰酸酯等。

The research breaks the concept that the aromatic isocyante shall be blocked by sodium bisulfate at low temperature.

该研究突破了亚硫酸氢钠封闭芳香族异氰酸酯需采用低温条件进行封闭的观念

The results showed that Japanese cedar, Ma bamboo and Makino bamboo all had a good liquefaction efficiency as liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 as a catalyst. The properties of PU foams made from liquefied woody material were influenced by the formulas of PU resins. Wherein, the PU foams made with a higher ratio of isocyanate would had a more complete crosslinking structure, a better mechanical properties and solvent resistance, and a lower water adsorption.

由试验结果得知，以PEG-400/glycerol为液化药剂，H2SO4为催化剂对柳杉、麻竹及桂竹均有良好之液化效果；液化木质材料所制造PU发泡体之性质受各成分调配比例所影响，其中异氰酸酯比例较高者，其PU树脂中液化木质材料之架桥反应较完全，发泡体机械性能及耐溶剂性较高，吸水性较低。

In this study, Japanese cedar, Ma bamboo and Makino bamboo were liquefied in polyethylene glycol/glycerol co-solvent with H2SO4 or HCl as catalyst. The liquefied woody materials were blended with PMDI (4,4'-Diphenylmethane diisocyanate;MDI) to prepare the PU foams. The effects of preparation conditions of PU resin on the properties of PU foams were investigated.
