please help me to answer theses question Synethesis of soap, What is the advantage of refluxing a solution as opposed to heating it in a beaker on a hot plate? why is it that the solution has 2 phase after doing the initial heating to melt the shortening? then after refluxing the solution why does it become homogeneous?

Why does a solid form at the interface of the two solutions? PROCEDURESynthesis of NylonIn a small beaker dissolve ~ 0.5 mL of sebacoyl chloride in 12 mL of ether. In a smalltest tube get ~ 6 mL (~1/4 of a 6 “ test tube) of 1,6-diaminohexane solution in water.In order to form the good polymer fibers, it is best to not mix the solutions. Youshould try to layer one solution on top of the other. First pour the 1,6-diaminohexanesolution into a 100 mL beaker. Then slowly pour the sebacoyl chloride down the sideof the tilted beaker with minimal mixing. At this point you should see two distinctlayers with a white film at the interface. Hook the nylon which forms at the interfacewith a straightened paper clip and pull slowly straight up as high as possible. Thenwrap it around your large beaker and then continue to wind the polymer around tillthe reaction is complete. Rinse your polymer in DI water to remove any salts or acidthat may be present.Weigh your product and characterize it by…
