A cooling bath or ice bath, in laboratory chemistry practice, is a liquid mixture which is used to maintain low temperatures, typically between 13 C and −196 C.These low temperatures are used to collect liquids after distillation, to remove solvents using a rotary evaporator, or to perform a chemical reaction below room temperature (see Kinetic control).

Get DetailsDestructive distillation is a chemical process in which decomposition of unprocessed material is achieved by heating it to a high temperature; the term generally applies to processing of organic material in the absence of air or in the presence of limited amounts of oxygen or other reagents, catalysts, or solvents, such as steam or phenols.It is an application of pyrolysis.

Get DetailsMar 30, 2022 Step 4: Evaporate the Methanol. Gently heat the mixture overnight to evaporate the methanol. As the methanol evaporates, 5-MeO-DMT “oil slicks” form on the surface of the liquid. Step 5: Purify the 5-MeO-DMT. Now that the 5-MeO-DMT is created, it needs to be separated from the rest of the elements in the mixture.
