ABSTRACT:
A method is provided for inhibiting the formation of hydrates in streams containing low-boiling hydrocarbons and water. The method includes adding to the stream a component of the formula: ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 are independently chosen from the group consisting of normal and branched alkyls having at least 4 carbon atoms,
