Description
Tetrabutyl titanate (CAS 5593-70-4, EC 227-006-8) is an organotitanium compound commercially known as titanium butoxide, butyl titanate, or TBT. It carries no assigned E-code. It is classified under HS code 29051900 and belongs to the catalysts and catalyst precursors category.
In plastics and polymer manufacturing, tetrabutyl titanate acts as a transesterification and polycondensation catalyst, accelerating ester-bond formation in PET and polyurethane production by coordinating with carbonyl oxygen. In personal care and food applications, it functions as a flavorant and fragrance component, where controlled hydrolysis generates reactive intermediates that contribute to target sensory profiles.
Tetrabutyl titanate is supplied as a liquid and is available in catalyst-grade and technical-grade specifications. It is subject to REACH registration requirements within the EU. Procurement teams should confirm grade suitability against FCC or internal formulation standards, as purity thresholds vary between food-contact and industrial catalyst applications.
