Abstract

fettsyreestere med den generelle formelen (I) R'-COO-(CnH2nO)x-R2 anvendes for å fjerne faste asfaltrester fra overflaten på petroleumsinstallasjoner eller petroleumsformasjoner rundt petroleumsborehull. I formel (I) R'-COO-(CnH2nO)x-R2 står R1 står for en alkylradikal med 6 til 22 C-atomer eller for et (CH2)m-COOR4 radikal, R2 og R4 står uavhengig for et alkylradikal med l til 8 C-atomer, n er lik på 2 eller 3, m er lik l til 6 og x er lik O eller et tall fra l og 12.
