In chemistry, a phase transfer catalyst, often known as a PTC, is a catalyst that makes it easier for a reactant to move from one phase of a heterogeneous system to another, where reaction can occur. Without a phase transfer catalyst, ionic reactants are frequently soluble in an aqueous phase but insoluble in an organic phase. Phase transfer catalysis is the term used to describe how a phase transfer catalyst speeds up a reaction. The primary method for creating chemical products with practical applications, such as medications, plant protection agents, dyes, photography chemicals, monomers, etc., is called organic synthesis. Starting materials must typically undergo a variety of chemical reactions involving the use of additional reagents, catalysts, solvents, etc. to transform into the desired final products. Due to the non-quantitative and non-selective nature of the procedures used to change ejects into products, and in especially because of the usage of these extra components, many waste materials are created during synthesis in addition to the desired products. These wastes need to be recycled, destroyed, and disposed of, which uses a lot of energy and puts a lot of strain on the environment. Therefore, it is crucial to create and apply synthetic approaches that reduce these issues. Phase-transfer catalysis (PTC) is possibly one of the most versatile and effective methods that meets this condition. A special use of heterogeneous catalysis known as phase transfer catalyst (PTC) quickens the transition of the reactant between phases. It is one of the exceptional and promising approaches for the synthesis of organic molecules. Since they reduce the need for organic solvents and enable the use of water, phase-transfer catalysts are very useful in green chemistry. Contrary to popular opinion, PTC in a system can be caused by both hydrophilic and hydrophobic reactants. In liquid/solid and liquid/gas processes, PTC is sometimes used. This review article will discuss the role that PTC can play in green chemistry.
