As nouns the difference between automation and automatization is that automation is the act or process of converting the controlling of a machine or device to a more automatic system, such as computer or electronic controls while automatization is a process of making an action of a higher animal reflexive.
In organic chemistry, transesterification /ËtraenzËÉstÉrÉ¨fÉ¨ËkeÉªÊÉn/ ËtrÃ¦nzËÉstÉrÉ¨fÉ¨ËkeÉªÊÉn is the process of exchanging the organic Groupâ³ r of an ester with the organic Groupâ² r of an. alcoholhe reverse reaction, methanolysis, is also an example of transesterification. This process has been used to recycle polyesters into individual monomers (see plastic recycling). It is also used to convert fats (triglycerides) into biodiesel.
