CHEMICAL NAME : n-Butyltris(2-ethylhexanoate)tin

FORMULA : C28H54O6Sn

CAS NO. : 23850-94-4

 

Description:

n-Butyltris(2-ethylhexanoate)tin is a light yellow transparent liquid, soluble in most organic solvents, insoluble in water. It is a kind of esterification catalyst with low amount of hydrolysis and high catalytic activity. It is mainly used for esterification and polycondensation with reaction temperature of 210~240 "C, and the maximum reaction temperature can reach 250C. The catalyst is neutral and has no corrosive effect on the equipment. After the reaction is completed, it does not need to be separated and does not affect the quality of the final product.
