You are on a multiple-product tankship and scheduled to load a cargo classed as an aromatic amine. This cargo is incompatible with cargoes classed as __________.
• Cargo compatibility tables in 46 CFR (especially for dangerous chemicals) • General reactivity of aromatic amines with other organic functional groups • Why certain combinations can lead to polymerization, heat release, or toxic by‑products
• Think about which functional group is most likely to react strongly with an aromatic amine rather than just sit together safely in a tank or piping system. • Ask yourself which type of cargo, if mixed with an aromatic amine, could create a significant chemical reaction risk (heat, pressure, or decomposition). • Consider what the Coast Guard chemical compatibility requirements are trying to prevent when they say a cargo is "incompatible".
• Check the chemical compatibility guidance used for tank vessels carrying dangerous chemicals (46 CFR chemical compatibility references). • Verify which of the listed groups is specifically flagged as incompatible with amines in standard cargo compatibility references, rather than just "use caution" or "separate". • Confirm in your mind the basic chemical behavior of amines with each listed group: phenols, esters, organic anhydrides, and ketones.
