The Role of Esterification in Industrial Manufacturing

Esterification is a pivotal process in industrial manufacturing, contributing to the production of a plethora of specialty chemical applications in the production of bulk and commodity chemicals. This chemical reaction combines an acid and an alcohol to form an ester, a component critical in various industrial applications from pharmaceuticals to adhesives and coatings[1].

The importance of esterification stems from the versatility of esters themselves. Depending on the specific acid and alcohol used, esters can have wide-ranging physical and chemical properties, making them adaptable to many different applications, including coatings, adhesives and sealants, composites, elastomers, personal care and lubricants.  They can be found in pharmaceuticals where they are used as pro-drugs, in adhesives and coatings due to their bonding capabilities and resistance properties, and in plastics for their flexibility and durability.[2]

In addition to their versatility, the esterification process is commonly used due to its relative simplicity and cost-effectiveness. Under the right conditions, acids and alcohols readily react to form esters, making it an accessible reaction for many industrial processes. The ability to create complex molecules through a straightforward process underscores the esterification reaction’s importance in the chemical industry and manufacturing.[3]

Inorganic Tin and Organotin Compounds: Essential Ingredients for Esterification

Tin catalysts are commonly used in the synthesis of a wide range of mono- and polyesters and alkyds. In regard to polyesters, tin catalysts are used primarily in the production of saturated polyesters used in various coatings applications. Saturated Polyester polyols are one of the key raw materials used in producing polyurethanes.  Tin catalysts are also used in the synthesis of unsaturated polyesters,  such as those used in the production of various plastic composites. Inorganic tin and organotin catalysts such as REAXIS® C125 (Stannous Neodecanoate) REAXIS® C129 (Stannous Octoate) Stannous Chloride (both in dihydrate as REAXIS® C154 and anhydrous as REAXIS® C162), REAXIS® C160, (Stannous Oxalate) REAXIS® C188 (Stannous Oxide) REAXIS® C216  (Dioctyltin Dilaurate) REAXIS® C220 (Monobutyltin Tris-(2-Ethylhexanoate)) REAXIS® C233 (Dibutlytin Diacetate) and REAXIS® C248 (Dibutyltin Oxide) are commonly employed.
