(FR) PROCÉDÉ POUR L'ÉLIMINATION DE SALISSURE
Abstract:
(EN) The invention relates to a process for removing fouling on a surface, wherein the surface is contacted with an aqueous solution of a guanidine of formula R1R2N-C ( =NH) -NR3R4 (I) wherein R1,R2, R3 and R4 may be the same or different and each of R1, R2, R3 and R4 is hydrogen or hydrocarbyl.
(FR) L'invention porte sur un procédé pour l'élimination de salissure d'une surface, suivant lequel la surface est mise en contact avec une solution aqueuse d'une guanidine de formule R1R2N-C(=NH)-NR3R4 (I) dans laquelle R1, R2, R3 et R4 peuvent être identiques ou différents et chacun parmi R1, R2, R3 et R4 représente hydrogène ou hydrocarbyle.
