Structures of a clathrate hydrate former, inhibitor, and synergist in water.

Perrin, Andrea and Goodwin, Melissa J. and Callear, Samantha and Soper, Alan K. and Musa, Osama M. and Steed, Jonathan W. (2018) 'Structures of a clathrate hydrate former, inhibitor, and synergist in water.', Journal of physical chemistry B., 122 (18). pp. 4901-4912.

Abstract

SANS studies are reported for aqueous THF at the 1:17 clathrate hydrate-forming composition and on aqueous solutions of the synergist 2-butoxyethanol. Addition of the clathrate hydrate inhibitor polyvinylcaprolactam and a dimeric model compound, 1,3-bis(caprolactamyl)butane, show that the inhibitors do not significantly affect the solution structures of these two important species in clathrate hydrate formation and inhibition. The SANS studies show that 1,3-bis(caprolactamyl)butane is a good model for polyvinylcaprolactam, and both the polymer and model compound exhibit hydrogen bonding interactions with water but do not interact significantly with 2-butoxyethanol in aqueous solution.
