Popis: Pure conjugated methylcis-trans andtrans-trans octadecadienoates have been prepared and used to develop a method for the determination of these compounds by infrared spectrometry.Cis-trans compounds alone or in the presence oftrans-trans conjugation may be determined directly by the absorption at 10.55 μ. In the absence ofcis-trans isomers conjugatedtrans-trans octadienoates may be determined directly from the absorption at 10.11 μ. When both types of compounds are present however, a correction must be applied for the contribution of thecis-trans isomers to the 10.11 μ absorption of thetrans-trans material.
