ARN

Portuguese to English Tech/Engineering Petroleum Eng/Sci QUIMICA
LABORATÓRIO DE CROMATOGRAFIA LÍQUIDA
LAUDO TÉCNICO

OBJETIVO
Caracterizar ácidos naftênicos na amostra de óleo do poço XXXXX, incluindo ácidos do tipo ARN.
...
A análise por FT-ICR-MS foi feita com varredura de massas até 1200 Da, o que exclui os íons de ácidos ARN resultantes de uma única ionização ([M-H]-).
CONCLUSÃO

....
Íons [M-H]- do ácido ARN C80H146O4

Ácidos naftênicos do tipo ARN foram detectados na amostra, porém em concentração muito pequena. Isso não elimina ou confirma o risco da formação de depósitos de sais de cálcio de ARN, pois não há dados históricos na ZZZZZZ que permitam a correlação entre a detecção de ácidos ARN e episódios de deposição.


Thanks in advance. 'C80H146O4' appears to be an example of an 'ácido ARN'.

Hits Re 'c80h146o4' (letter 'O,' 4), I got no hits either. I have two graphs (intensity/wavelength); one is marked with an arrow to a data point -

Íons [M-H]- do ácido ARN C80H146O4. The other says simply
Íons [M-H]- de ácidos ARN

The relevant literature uses 'AN' to refer to Ácido Naftênico. But I looked for a long time and found no likely candidates for ARN. The text is largely free of English words, except for such acronyms as 'HPLC-MS', so maybe ARN is in fact English. 'RNA' - as far as my limited chemistry goes - seems improbable and does not pattern with anything else.

Hi
Are you sure you've got the formula right?
C80H146O4

I am getting zero hits for this.
