Disclosed are chemical products useful for crude oil conditioning, particularly to demulsifying basic compounds. Disclosed are PEO w -PPO y -PEO w triblock bipolymers, with amphoteric groups, β-amino acid derivatives, at the chain ends, which destabilize water-in-crude oil (W/O) emulsions, thereby removing emulsified water and salts dissolved salts in the aforementioned phase. |
