Certain substituted amines, alkylenediamines or polyamines, and derivatives of these, are suitable for use in preventing, inhibiting, or otherwise modifyin g crystalline gas hydrate formation. These inhibitors include compounds from any of the following groups. (see formula 1) (see formula 2) (see formula 3) (see formula 3b) (see formul a 4) (see formula 5) (see formula 6) (see formula 7a) (see formula 7b) The substituents R1 - R5 may be hydrocarbyl groups or, in some cases, polyhydroxyalkyl groups or (CH2)p-COO- in which p is either 1 or 2.
