Liners mantle

The autoclave is allowed to cool overnight in the heating mantle, to ensure slow crystallization of the product. The pressure is then released, the liner tube is removed from the autoclave, and the yellow solution is decanted immediately and discarded. The checkers observed a red-orange solution at this point, which could be due to the presence of Ru6(ethylene) derivatives if the prescribed reaction time is exceeded. 

When designing components of pumps subject to torsion and bending loads, such as shaft sleeves and pump casings, it is important to appreciate that the harder the material, the narrower the limit on strain or elongation. A range of elongation of 0.5% to 1.5% is a minimum for bowls, mantle liners, pump-wetted parts, ball mill grates, and components... 

Heptane (50 mL) is added to a 100-mL autoclave liner tube containing Ru3(CO)i2 (400 mg, 0.626 mmol) and a Teflon-coated stirring bar. The autoclave is assembled and pressurized twice to 30 atm of ethylene. Then, the ethylene is vented to atmospheric pressure and the autoclave is Anally repressurized with ethylene to 30 atm and sealed. The pressure will drop to 15 to 20 atm on stirring. The autoclave is then heated to 165 °C over a period of 0.75 h, with rapid stirring, and maintained at 165°C for an additional 4.25 h (thermocouple measuring temperature at the interface between autoclave and heating mantle).
