Do you know how many types and synthesis methods there are for titanate coupling agents?

Titanates can be divided into four types according to their chemical structures: monooxyalkyl type, monooxyalkyl pyrophosphate type, chelating type, and coordination type. These different types of titanates have a wide range of applications in various fields.

The general synthesis of titanate coupling agents involves two steps. The first step is the formation of tetraalkyl titanate, which can be achieved through multiple methods, but the most commonly used is the direct method, where tetrachlorotitanic acid and the corresponding alcohol react directly to synthesize it. The second step is the synthesis of the final coupling agent, where further reactions with different fatty acids convert the tetraalkyl titanate into the desired type of titanate coupling agent. This synthetic method has the advantages of simple process and low cost, making it commonly used in industry.
