Abstract
A method for inhibiting formation of hydrocarbon hydrates in mixtures of water and a hydrate-forming guest molecule involves adding a reaction product to the mixtures in an effective amount to inhibit formation of the hydrocarbon hydrates under conditions otherwise effective to form the hydrocarbon hydrates in the absence of the reaction product. The product is made by the reaction of first reactant that is an amine or polyamine, or alcohol or polyalcohol, with a second, aldehyde reactant and a third reactant that is an alcohol or polyalcohol or, an amide or polyamide. Preferably, if the first and third reactants are both an alcohol or both a polyalcohol, they are not the same. A non-limiting example of a suitable amine would be a fatty alkyl amine, while formaldehyde would be a non-limiting of a suitable aldehyde and polyacrylamide would be a suitable third reactant.
