Kinetics and Mechanism of Acetylene Hydrogenation Catalyzed by AuCL_3 KBH_4 KBH H_2O System

AuCl3-KBH4-H2O体系对乙炔的选择性催化加氢活性及反应机理

Polymer-supported borohydride reagents ( BER ) have been prepared by reaction ofKBH _ 4 with 717 ~ # anion exchange resin.

用KBH_4与717~ # 阴离子交换树脂反应制备了聚合物支载的硼氢化试剂 ( BER ).

To make all the users around the world satisfied and proud of our products is the mission to KBH.

让全世界和睿家具的使用者感到自豪，也正是KBH的使命。

The experimental conditions and instrumental operation parameters such as KBH 4 concentration, flow rate of the carrier and shield gas, currents of lamp were optimized.

优化了光电管负高压，灯电流，屏蔽气和载气流量等实验条件。

Compared with KBH and glucose, formaldehyde is a good reducing agent for the silver catalyst preparation.

结果表明，还原剂的选择和搅拌强度对催化剂的活性有明显影响，与硼氢化钾和葡萄糖相比，甲醛是一种优良的制备银催化剂的还原剂；

Builders with higher debt, such as KB home ( KBH), Beazer ( bzh), and hovnanian whose debt levels range from 77% to 186% of market cap, will likely see a slower rebound, he says.

他还说，负债较高的建筑商，比如KB Home、Beazer和霍夫纳尼安的债务水平介于市值的77-186%，它们反弹速度可能会慢一些。
