Patent

CA 2162252

The invention concerns the use, for making hydrocarbons, of aminotriarylmethanes of formula (I) in which the ring A may be benzoanellated; R1 and R2 are optionally substituted C1-C13 alkyl or optionally substituted phenyl or R1 and R2 together with the nitrogen atom to which they are bound are a heterocyclic group, whereby R1 may also be hydrogen; R3 and R4 ae optionally substituted C1-C20 alkyl, whereby R3 may be hydrogen; and X1 and x2 are optionally substituted C1-C13 alkyl, a group of the formula NR1R2 or one of the groups X1 and X2 or hydrogen. The invention also concerns hydrocarbons containing such aminotriarylmethanes, a method of detecting the presence of such aminotriarymethanes in hydrocarbons and new aminotriarylmethanes.

Utilisation d'aminotriarylméthanes répondant à la formule (I), dans laquelle le noyau A peut être benzo-annelé, et R<1> et R<2> désignent un alkyle en C1-C13 éventuellement substitué, un phényle éventuellement substitué, ou bien R<1> et R<2> forment, conjointement avec l'atome d'azote les liant, un reste hétérocyclique, ou bien R<1> est également un hydrogène; R<3> et R<4> désignent un alkyle en C1-C20 éventuellement substitué, ou R<3> est également un hydrogène; et X<1> et X<2> désignent un alkyle en C1-C13 éventuellement substitué, un reste de formule NR<1>R<2>, ou l'un des deux restes X<1> X<2> ou bien un hydrogène, pour le marquage d'hydrocarures, hydrocarbures renfermant les aminotriarylméthanes précités, procédé permettant la détection de tels aminotriarylméthanes dans les hydrocarbures, et nouveaux aminotriarylméthanes.
