CA 2392061

Petroleum additive formulations include a petroleum additive dissolved in a carrier fluid including at least one compound of the formula (I): (R2)p-Ph- (CH2)m-COO-(AO)n-R1 where; R1 is C1 to C10 alkyl; AO is alkyleneoxy; n is 0 or from 1 to 100; m is 0, 1 or 2; and Ph is a phenyl group, which may be substituted with groups (R2)p; where each R2 is independently C1 to C4 alkyl or alkoxy; and p is 0, 1 or 2. Further, crude petroleum or petroleum refinery streams can be treated by adding a petroleum additive dissolved in a carrier fluid of the formula (I) to the product stream. Desirably the carrier fluid is or includes iso-propyl benzoate and/or 2-ethyl hexyl benzoate.

L'invention concerne des formulations d'additifs pétroliers contenant un additif pétrolier dissout dans un liquide porteur comportant au moins un composé de la formule (I) : (R?2¿)¿p?-Ph-(CH¿2?)¿m?-COO-(OA)¿n?-R?1¿, dans laquelle R?1¿ représente un C¿1? à C¿10? alkyle, OA représente un alkyléneoxy, n est 0 ou un entier compris entre 1 et 100, m est 0, 1, ou 2, et Ph est un groupe phényle pouvant être substitué avec des groupes (R?2¿)¿p?, R?2¿ représentant indépendamment du C¿1? à C¿4? alkyle ou alkoxy, et p étant 0, 1, ou 2. Par ailleurs, des flux de pétrole brut ou provenant de raffineries de pétrole peuvent être traités par addition d'un additif pétrolier dissout dans un liquide porteur de la formule (I) au flux de produit. Idéalement, le liquide porteur est ou contient de l'iso-propyl-benzoate et/ou du 2-éthylhexyl-benzoate.
