    • This invention relates to the use of a supplemental promoter in conjunction with a noble-metal-containing catalyst comprising a carbon support in catalyzing liquid phase oxidation reactions, a process for making of an improved catalyst comprising such a supplemental promoter, and an improved catalyst comprising such a supplemental promoter. In a particularly preferred embodiment, a supplemental promoter (most preferably bismuth or tellurium) is used in conjunction with a noble-metal-containing catalyst comprising a carbon support in a liquid phase oxidation process wherein N-(phosphonomethyl)iminodiacetic acid (i.e., “PMIDA”) or a salt thereof is oxidized to form N-(phosphonomethyl)glycine (i.e., “glyphosate”) or a salt thereof. The benefits of such a process include increased oxidation of the formaldehyde and formic acid by-products, and, consequently, decreased final concentrations of those by-products as well as other undesirable by-products, most notably N-methyl-N-(phosphonomethyl)glycine (i.e., “NMG”).
    • 本发明涉及补充促进剂与包含碳载体催化液相氧化反应的含贵金属的催化剂的使用,制备包含这种补充促进剂的改进的催化剂的方法,以及改进的催化剂,包括 这样的补充推动者。 在特别优选的实施方案中,补充促进剂(最优选铋或碲)与液相氧化方法中含有碳载体的含贵金属的催化剂结合使用,其中N-(膦酰基甲基)亚氨基二乙酸(即“ PMIDA“)或其盐被氧化形成N-(膦酰基甲基)甘氨酸(即”草甘膦“)或其盐。 这种方法的好处包括增加甲醛和甲酸副产物的氧化,从而减少那些副产物以及其它不希望的副产物的最终浓度,特别是N-甲基-N-(膦酰甲基 )甘氨酸(即“NMG”)。

    • A modular scaffold component of different material components advantageously uses the durability and reliability of conventional type steel ledger heads adhesively secured to by an aluminum or aluminum alloy structural member. In a preferred embodiment the structural member is an extruded elongate tube and in a further preferred structure the elongate tube is of a non circular cross section having thickened top and bottom portions preferably interior to a circular outer surface. These thickened portions provide additional strength and structural characteristics such that the component can be freely substituted for the equivalent steel component. In this way the component may be added to existing systems to take advantage of the reduced weight thereof without requiring a dedicated system or rendering an existing system obsolete.
    • 不同材料组件的模块化支架部件有利地使用粘合地由铝或铝合金结构构件固定的常规型钢分类帐头的耐久性和可靠性。 在优选实施例中,结构构件是挤出的细长管,并且在进一步优选的结构中,细长管是非圆形横截面,具有较厚的顶部和底部部分,优选在圆形外表面的内部。 这些加厚部分提供额外的强度和结构特征,使得该部件可以自由地代替等效的钢部件。 以这种方式,可以将组件添加到现有系统以利用其减轻的重量,而不需要专用系统或使现有系统变得过时。
