The dividing line between what we call soluble and what we call insoluble is arbitrary, but the following are common criteria for describing substances as insoluble, soluble, or moderately soluble. If less than 1 gram of the substance will dissolve in 100 milliliters (or 100 g) of solvent, the substance is considered insoluble.

Previously, no patent application was made because the methanolysis process requires a large investment compared to the glycolysis process in separating and purifying mixtures of glycols, alcohols, phthalate derivatives, etc. From 1990 to 1997, Eastman Kodak filed an active patent application for methanolysis.
Crystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of crystal lattice is called a unit cell, which can accept atoms or molecules to grow a macroscopic crystal. During crystallization, atoms and molecules ...
