Study on Synthesis and Properties of a Novel Borate Ester Surfactant

摘要：

A new type of surfactant was prepared. The structure of the novel borate ester formed by reacting boric acid and lauryl alcohol and with diethanol amine was established by 11B, 1H NMR spectroscopy and IR spectrum. Testing it antistatic property, we found 0.3wt％ dodecanol diethanol amine borate ester surfactant (the final product LNB) can make specific resistance of the polyester staple fiber be decreased from 1012 to 108 at the condition of 60％ RH and 18°C. Because Amine compounds with nonbonding electrons can form the extra molecular coordination bond of nitrogen to boron and prevent hydrolysis of borate esters, it exhibits higher hydrolytic stability. And the novel borate ester surfactant shows a higher antibacterial activity. This paper mainly studies its application in modern spin finishes for polyester staple fiber.
