Abstract

Anvendelse av benzaldehyder med formelen Ri W c ^"^ R3 hvor ringen A kan være benzoanellert, og hvor R^, r2 og R^ uavhengig av hverandre i hvert tilfelle betyr hydrogen, hydroksy, Ci-Ci5-alkyl, C^-C^^. alkoksy, cyano, nitro eller en rest: med formelen nr4r5 eller COOR^, hvor R** står for hydrogen eller Ci-C]_5-alkyl, R^ står for eventuelt substituert C]_-Ci5-alkyl, eller en rest med formelen L-NX^X^, hvor L har betydningen av C2-Cg-alkylen og X^ og X^ uavhengig av hverandre i hvert tilfelle har betydningen av C]_-Cg-alkyl eller sammen med nitrogenatomet som forbinder har betydningen av en heterocyklisk rest, og R^ står for hydrogen, eventuelt substituert C]_- Ci5-alkyl, eller for en rest med formelen L- NX^X^, hvor L, X^ og x2 i hvert tilfelle har den ovennevnte betydning, som markeringsmidler for hydrokarboner, en fremgangs- måte for påvisning av disse benzaldehyder i hydrokar- boner, samt hydrokarboner som inneholder de ovennevnte benzaldehyder.The use of benzaldehydes of the formula R 1 W c 2 R 3 where the ring A may be benzoanellated and wherein R 1, R 2 and R 2 independently in each case means hydrogen, hydroxy, C 1 -C 15 alkyl, C 1 -C 2 alkoxy, cyano, nitro or a residue: of formula # 4R5 or COOR4, wherein R18 represents hydrogen or C1-C5 alkyl, R4 represents optionally substituted C1-C15 alkyl, or a residue of the formula L-NX ^ X ^, where L has the meaning of C₂-Cg alkylene and X ^ and X ^ independently in each case have the meaning of C]-Cg alkyl or together with the nitrogen atom connecting has the meaning represents a hydrogen, optionally substituted C1-C15 alkyl, or a residue of the formula L-NX2 X4, wherein L, X2 and x2 are in each case the above meaning, as marking agents for hydrocarbons, a method for detecting these benzaldehydes in hydrocarbons, as well as hydrocarbons containing the above-mentioned benzaldehydes.
