Recrystallization and Acid/Base Extraction

Salt The product from the reaction of an acid and a base Freebase The natural form of a drug, hasn't been reacted with an acid. You can change it back and forth between its freebase and salt form as many times as you want. Explanation of A/B (acid base) extraction. Most drugs have an amine group. This is a NH 2 attached to the molecule somewhere.

What is the role of salt in DNA extraction?

Answer (1 of 3): Saltingout proteins in a sample that contains DNA (usually a blood sample) is a cheap and highly effective step in separating nonDNA (cell walls, cellular proteins and other unwanted substances) molecules from DNA molecules. Basically, it's a procedure where one "dismantles" th...

PGM Extraction | Hydrocaronyl Processes

In most cases, the wellknown hydrometallurgical process is applied, which involves dissolution of metals by hydrochlorination. Pt is separated by precipitation of the ammonium salt, ammonium hexachloroplatinate (NH 4) 2 [PtCl 6], which is further calcined to obtain sponge Pt. From the filtrate, Pd is extracted in the form [PdCl 2 (NH 3) 2].

Basic Methods of Salt Production

· Salt production is one of the oldest chemical practices performed by man. Although salt is produced naturally when seawater evaporates, the process can easily be reproduced to create a higher yield. Some salt is still produced using ancient methods, but new, faster, and less expensive methods have been developed.

History of Salt | SaltWorks®

A major portion of this writing is devoted to a discussion of more than 40 kinds of salt, including descriptions of two methods of salt extraction that are similar to processes used today. Salt production has been important in China for two millennia or more, and the Chinese, like many other governments over time, realized that taxing salt would could be a major revenue source.

· Extraction of metals from their compounds is also a reduction process. Besides using carbon (coke) to reduce metal oxides to metals, sometimes displacement reactions can also be used. The highly reactive metals such as sodium, calcium, aluminum, etc. are used as reducing agents because they can displace metals of lower reactivity from their compounds.

Crystallisation process. Hot steam at 140°C causes the brine to boil in the evaporator. The steam that is formed (now referred to as "flash steam") is fed away from the top of the evaporator. The salt crystallises continuously and collects at the lower end of the evaporator as a wet paste. Schweizerhalle Saltworks operates six evaporators.
