查询词典 isocyanate

A series of 3,5-disubstituted chiral hydantoins were prepared from D-amino acid and phenyl isocyanate in mixed solvent, and the catalyst was then supported on macroporous adsorption resins.

摘 要：以混合溶剂法由D 氨基酸和异氰酸酯制备一系列3，5 二取代手性海因，用大孔吸附树脂作载体，制成固载型手性催化剂，并考察了不同结构手性海因化合物在3 苯氧基苯甲醛氰醇化反应中的催化活性。

Kinetics of hydroxyl-terminated polybutadiene/ phenyl isocyanate, bonding agent (BA-5)/PI and antioxidant H/PI were studied in toluene/dimethyl sulphoxide solution. The rate constants and the activation parameters were calculated. The results show that the reactionary rate of these three active hydrogen components decreased in same condition.

分别对端羟基聚丁二烯/苯异氰酸酯，键合剂(BA-5)/PI和防老剂H（N，N'-二苯基对苯二胺）／PI在甲苯／二甲基亚砜混合溶液体系中进行了反应动力学研究，计算了相应体系的反应速率和活化能。

The results indicate that Phenylisothiocyanate can insert into the lanthanide alkyl bond of organolanthanide complexes to give mono-insertion product,〓 [Ln=Y (35) ] and 〓 as phenyl isocyanate does.

得到了单插入产物〓[Ln=Y（35）]和〓。

It is further provided an apparatus comprising heating means (22) in thermal communication with a sample holder (31) suitable for the containment of the material, the sample holder being in gaseous communication (12) with a sansing region (6), the apparatus being further provided with a means (9) for inducing flow of gas from the sample holder of the sensing region and a means (9) for sensing the presence of hydrogen isocyanate in the sensing region.

而且还提供了一种装置，包括与适于留存材料的样品储存器(31)热连接的加热装置(22)，该样品储存器与传感区域(6)相互气体连接(12)，该装置进一步设置有：用于从传感区域的样品储存器引导气体流动的装置(9)和用于检测传感区域中异氰酸的存在的装置(9)。

An agent for a protective film which comprises a liquid mixture of a urethane type compound, methyl ethyl ketone and ethyl acetate and a curing rate enhancing agent comprising an isocyanate type compound and ethyl acetate; and a method for forming a protective film which comprises applying the agent for a protective film on the outer surface of a mold (9) or on the region of the outer surface of the mold (9) except a specific portion as an article to be coated.

本发明提供了一种保护膜制剂和形成保护膜的方法，其中所述保护膜制剂含有聚氨酯型化合物、甲基乙基酮和乙酸乙酯的液体混合物与含有异氰酸酯型化合物和乙酸乙酯的固化增速剂；所述形成保护膜的方法包括将保护膜制剂涂布于模具(9)的外表面或涂布于模具(9)的外表面除了作为待涂布制品的特定部分以外的区域。

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。

Singer Leona Lewis and former Led Zeppelin guitarist Jimmy Page emerged as the bus transformed into a grass-covered carnival float, and the pair combined for a rendition of "Whole Lotta Love".

歌手leona刘易斯和前率领的飞艇的吉他手吉米页出现巴士转化为基层所涵盖的嘉年华花车，和一双合并为一移交&整个lotta爱&。

This is Kate, and that's Erin.
