In this study, several novel and natural hydrophobic deep eutectic solvents (D.E.Ss) were prepared using Me trioctylammonium chloride (M.T.O.A.C) as H. B. A and different types of straight chain alcs. as H. B.Ds. One of the D. E.Ss composed of M. T. O. A. C and n-butanol was advantageously used to develop an ultrasound-assisted dispersive liquid-liquid microextraction (U.A-D.L.L.M.E) method combined with high-performance liquid chromatog.-UV detection (H.P.L.C-U.V) for the determination of some strobilurin fungicides in apple samples. Several important parameters influencing extraction efficiency were investigated and optimized, including the type and volume of extractant in ultrasound stage, sonication time, the type and volume of D. E. S, sample solution pH and effect of salt addition Under optimal exptl. conditions, the method showed good linearity with correlation coefficients (R2) of 0.9985 – 0.9991 in the linear range of 4-1500μg kg-1, low limits of detection of 1.5-2μg kg-1 and acceptable extraction recoveries in the range of 76-92%. Enrichment factor was in the range of 95-115. The proposed method was successfully applied for the extraction and preconcentration of trace fungicides in apple samples, and the results demonstrated the potential of the synthesized D. E. S for the extraction and determination of contaminants in aqueous samples. This study involved multiple reactions and reactants, such as N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3Computed Properties of C25H54ClN).
N-Methyl-N,N-dioctyloctan-1-aminium chloride (cas: 5137-55-3) belongs to organic chlorides. Chlorinated organic compounds are found in nearly every class of biomolecules and natural products including alkaloids, terpenes, amino acids, flavonoids, steroids, and fatty acids. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Computed Properties of C25H54ClN
