シロキシシランが高沸点のため蒸留精製ができないこと
による不純物の混入などの問題がある。However, these conventional methods have many drawbacks, particularly in the production of higher fatty acid acyloxysilane having 6 or more carbon atoms. 1)
In the above method, continuous production can be performed when a carboxylic acid having a small number of carbon atoms is used, but when a higher fatty acid is used, the reaction takes a lot of time. When pyridine, triethylamine or the like is used as a dehydrochlorinating agent, the reaction proceeds easily, but it is difficult to completely remove the by-produced hydrochloride. In the method 2), when an alkali metal salt of higher fatty acid is used, it is very difficult to remove it because the metal salt produced is dispersed in fine particles. In the method of 3),
When a higher fatty acid is used, its reactivity is low and it takes time, and it is difficult to remove the acid and alkali used for the catalyst. As described above, in the production of higher fatty acid acyloxysilane, there is a problem that reactivity of higher fatty acid is low, or impurities cannot be mixed because the acyloxysilane cannot be purified by distillation because of high boiling point.
