5 Advantages Of Phase Transfer Catalyst And How You Can Make Full Use Of It!
The basic principle of phase transfer catalysis (PTC) was introduces by Reuben and Sjoberg in the year 1981. The principle of phase transfer catalysis is generally based on the ability of certain PT catalysts also known as phase-transfer agents, in order to facilitate the transport of one reagent from one phase into another (immiscible) phase wherein the other reagent exists. Thus, reaction is made possible by bringing together the reagents which are originally in different phases.
Wide use of PTC in making inexpensive organic chemicals: Phase Transfer Catalysis is widely utilized as a part of the commercial manufacturing of chemicals of more than 10 billion dollars per year. PTC is likewise utilized as a part of prevention of pollution, its treatment and for the impurities removal in waste and product streams. The demand of PTC is increased in the chemical industries due to several convincing advantages it provides, especially for lessening the cost in making organic chemical as well as pollution prevention.
Can be used in place of Expensive Bases The use of PTC with inorganic base i.e. NaOH can easily replace the use of risky as well as expensive bases like sodium methylate, sodium amide or sodium hydride etc. In fact, PTC inorganic base systems are beneficial as well as very effective.
PTC provides easy work-up procedures A phase transfer catalyst is easily dis-solvable in 2 solvents, and it conveys anions of inorganic salts into natural solvents and returns them to the water phase. The Phase Transfer Catalysis reaction is generally carried out with easy work-up procedures and under mild conditions, which is also a main reason behind its increased industrial uses.
Can be used in several noteworthy Reactions The scope of PTC can be figured out by considering the scope of reactions to which PTC can be applied. The 1700 patents along with 8000 publications on PTC are in around 30 noteworthy reactions classifications. This scope of PTC utilization is amazingly wide and is one of the most important reasons behind the increased demand of PTC in chemical industries and its great importance.
Decreases the manufacturing cost Regardless of market conditions, process scale or country of manufacture, the ability of increase the isolated yield of a reaction is always a basic method in order to decrease its cost, prevent pollution and improve the raw material usage. PTC provides higher isolated yield because of the higher selectivity achieved by taking advantage of the high flexibility in designing the microenvironment of the reaction.
