CAS 23850-94-4 Butyltin tris(2-ethylhexanoate) is a light yellow transparent liquid that is soluble in most organic solvents and insoluble in water. It is a type of esterification catalyst that is resistant to hydrolysis and has low dosage and high catalytic activity. It is mainly used for esterification and condensation reactions at reaction temperatures of 210-240 ° C, with high reaction temperatures up to 250C. The catalyst is neutral and has no corrosive effect on the equipment. After the reaction is completed, there is no need to separate it, which does not affect the quality of the final product.
