| abstract |
The invention concerns the use, for making hydrocarbons, of aminotriarylmethanes of formula (I) in which the ring A may be benzoanellated; R<1> and R<2> are optionally substituted C1-C13 alkyl or optionally substituted phenyl or R<1> and R<2> together with the nitrogen atom to which they are bound are a heterocyclic group, whereby R<1> may also be hydrogen; R<3> and R<4> are optionally substituted C1-C20 alkyl, whereby R<3> may be hydrogen; and X<1> and X<2> are optionally substituted C1-C13 alkyl, a group of the formula NR<1>R<2> or one of the groups X<1> and X<2> or hydrogen. The invention also concerns hydrocarbons containing such aminotriarylmethanes, a method of detecting the presence of such aminotriarylmethanes in hydrocarbons and new aminotriarylmethanes. |
