A chemical engineer needs to select a lining material for an industrial reaction vessel. The vessel will contain highly acidic reactants at a temperature of 165 ∘C165\ ^\circ\text{C}165 ∘C. To ensure effective temperature regulation, the lining must also allow rapid heat transfer to an external cooling jacket.
The properties of four candidate materials are shown in the table below:
| Material | Maximum usable temperature (∘C^\circ\text{C}∘C) | Resistance to acids | Thermal conductivity |
|---|---|---|---|
| A | 140 | Excellent | High |
| B | 200 | Poor | High |
| C | 220 | Excellent | Low |
| D | 280 | Excellent | High |
Which material is best suited for this application?
Material A
Material B
Material C
Material D
