A process for inhibiting the deposit of paraffins in crude oils and petroleum fractions incorporating additives of the family of N-substituted succinimide ethers. The additives according to the invention make it possible, on the one hand, to maintain in dispersion the whole range of paraffins improving the flowing properties of crude oils and, on the other, to prevent the deposit of the heavier paraffins on the walls. Therefore, the process is effective during both the storage and the transportation of crude petroleum.

A process for inhibiting the deposit of paraffins in crude oils which comprises incorporating into th oil a paraffin deposit inhibiting amount of and N-substituted succinimide ether of the formulae: [Figure] (I) and [Figure] (II) wherein R1 and R2 each independently represent a linear saturated aliphatic radical containing 1 to about 25 carbon atoms, a linear unsaturated aliphatic radical containing 2 to about 25 carbon atoms, a branched saturated aliphatic radical containing 3 to about 25 carbon atoms and a branched unsaturated aliphatic radical containing 3 to about 25 carbon atoms, A and B each independently represent a linear alkylene radical containing from 2 to 4 carbonatoms, a branched alkylene radical containing from 3 to 4 carbon atoms; X represents an －NH－group or an oxygen atom －O－; n is an integer from 1 to 50; m is an integer from 0 to 4; and z is an integer from 0 to 5.
