Abstract Copper Alloy No. C93500 is a cast bronze containing nominally 9% lead and 5% tin. It has excellent machinability, low strength and good resistance to corrosion. It is used for corrosion-resistant castings, small bearings and bushings. This datasheet provides information on composition, physical properties, hardness, elasticity, tensile properties, and compressive strength as well as fracture toughness. It also includes information on corrosion resistance as well as casting, heat treating, machining, and joining. Filing Code: Cu-439. Producer or source: Copper alloy foundries.

Abstract Copper Alloy No. 165 is a copper-cadmium-tin alloy with low strength and high ductility in the annealed condition. In the hard-drawn condition, characterized by high strength and low ductility, it is used widely as an electrical conductor. This datasheet provides information on composition, physical properties, hardness, elasticity, and tensile properties as well as fatigue. It also includes information on corrosion resistance as well as forming, heat treating, machining, and joining. Filing Code: Cu-327. Producer or source: Copper and copper alloy mills.

Kinetic study of toluene and benzene alkylation with isopropyl alcohol on alumo- and ferrisilicates of MFI structure has shown that the alkylation activity does not follow the acidity (both the number and strength of bridging OH groups) of these molecular sieves. The rate of the overall reaction is controlled by the desorption/transport rate of bulky, strongly adsorbed cymenes and cumene. A higher concentration of n-propyltoluenes compared to n-propylbenzene, both undesired reaction products, formed via a bimolecular isomerization of isopropyl aromate with benzene or toluene, was due to the higher reactivity of isopropyltoluene with toluene in comparison with that of cumene with benzene. It is concluded that ferrisilicates of MFI structure possessing low strength acid sites appear to be promising catalysts for achieving both a high isopropyl- and para-selectivity in toluene alkylation to p-cymene.
