Abstract:
A method for preventing the formation of gas hydrates in an aqueous phase by adding esters of pyroglutamic acid in the quantities of from 0.01 to 2% by weight. The esters of pyroglutamic acid produced by esterifying at least one alcohols, comprising from 1 to 100 hydroxyl groups with pyroglutamic acid and/or glutamic acid, wherein the alcohol has no more than one ester group or no more than one carboxylic acid group.
