Abstract

Det er beskrevet anvendelse av pyroglutaminsyre estere, som kan fremstilles ved forestring av alkoholer som har I til I00 hydroksylgrupper med pyroglutaminsyre og/eller glutaminsyre, under den forutsetning at alkoholen ikke har mer enn en estergruppe eller ikke mer enn en karboksylsyregruppe, i mengder på 0,01 til 2 vekt% for forebyggelse av dannelsen av gasshydrater i vandige faser som er forbundet med en gassformig, flytende eller fast organisk fase.
