Molecular Formula: BuSnOOH Molecular Weight: 208.8 Solubility: White power, insoluble in water and most organics.Dissolves in strong alkaline and mineral acid solutions M.P. Decompose without melting Sn Content: 56.5 ± 0.5% Property: It is a solid,hydrolytically stable catalyst that is active at low loadings. It is used primarily to catalyst esterification and polycondensation reaction at temperature between 210 ℃ and 240 ℃ . It begines to solubilize in carboxylic acid at 80 ℃ during the reaction and become incorporated into the final product without affecting the quality of the product. It can be used at temperatures up to 250 ℃
