TIB KAT 256 is used primarily to catalyze esterification and polycondensation reactions at temperature between 210°C and 240°C (stable up to 250°C).
TIB KAT 256 begins to solubilize in carboxylic acid at 80°C during the reaction and becomes incorporated into the final product without affecting the quality of the product.
For this reason TIB KAT 256 does not require neutralization or filtration at the end of production.
TIB KAT 256 can significantly shorten esterification times, offers energy savings due to lower reaction temperatures, with a consequent more efficient use of equipment.
TIB KAT 256 minimizes side reactions such as dehydration and oxidative degradation of polyhydric alcohols, especially secondary alcohols.
TIB KAT 256 can be charged up front with other reactants, and requires no special handling other than avoiding excessive exposure to moisture.
Organotin compounds are an important product of tin deep processing, with the characteristics of various varieties and wide applications, and TIB KAT 256 is the fastest growing field of tin consumption.
Organotin products are used as heat stabilizers in plastic processing industries such as PVC, and have been widely used in industrialization.
As catalysts, they are widely used in chemical industries such as silica gel synthesis, polyurethane synthesis, and coating synthesis.
TIB KAT 256, also known as monobutyltin oxide, can be used to synthesize butyl tin series heat stabilizers and catalysts, and can also be used as a polyurethane catalyst, silica gel catalyst, and coating catalyst with excellent performance.
The current method for synthesizing butylstannoic acid has problems such as complex synthesis, difficult control, low conversion rate, and low product purity.
Overcoming these problems is an important topic in the chemical industry.
