Efek elektronik serapan infra merah pada pengukuran TBP dan capuran MBP + DBP

The measurement band P=0 the trybuthylphosphat (TBP) and dibuthylphosphat (DBP) + monobuthyphiosphat (MBP) mixture by infra red absorbtion. This measurement was carried out using CaF2 window cell, period 6, alith width 0,3 mm, gain l, speed 150 cm -1, per minute and absorption band range 1300 - 1120 cm -1 on beckmann spectrophotometer IR 4250. The electronic effect P=0 band of CH3-CH2-CH2-CH2- (buthyl) caused absorption band of TBP was 1285 cm -1 while (40% MBP + 40% DBP) mixture was 1260 cm -1.
