The study of binary phase diagram of palm-oil based maltosides (MPO)

The objectives of this research project are to prepare the sample of palm-oil based maltosides (MPO) and to observe the sample by using thin cross polarizer at four different temperature which is the room temperature, 30℃, 40℃, 50℃ and 60℃. The results are two phases are probably formed within this phase diagram which is the viscous isotropic phase and viscous isotropic plus water phase. The anisotropic is probably not exist in MPO liquid crystalline since no birefringence phase observe during the experiment. Another objective is to analyze the phases of lyotropic liquid crystals appear in MPO using Optical Polarizing Microscope (OPM). The temperature used to analyze this substance is 30℃, 40℃, 50℃ and 60℃. Each sample is needed to go through heating process until isotropic phase appear and for MPO, the temperature for isotropic phase is 280℃. The sample is left for cooling process back to its initial temperature and observation is recorded each 5 minute once the process of heating-cooling started. Based on this analysis, it is observe that there might be two isotropic phases appear with MPO which is the micellar isotropic phase and lamellar isotropic phase.
