Twin-tailed hydrophobic monomer N,N-di-n-dodecylacrylamide had been synthesized by the reaction of acryloyl chloride with N,N-di-n-dodecylamine which prepared by laurylamine and 1-bromododecane.

Ti-containing mesoporous molecular sieve Ti-HMS was synthesized at ambient temperature using dodecyl amine(DDA) as template, tetraethylorthosilicalite (TEOS) as silicon source and tetrabutylorthotitanate (TBOT) as titanium source.

Using dodecyl amine (DDA)as a template , tetraethyl orthosilicate(TEOS) as a silica source, titanium sulfate as a titanium source, and ferric chloride as a iron source, mesoporous molecular sieve HMS, Ti-HMS and Fe/Ti-HMS were synthesized at ambient temperature by the sol-gel method.

Effect of pH Value on the Adsorption Behavior and Inhibition Mechanism of Dodecylamine on Carbon Steel;

Ti-HMS was synthesized at ambient temperature using dodecylamine as the template,tetraethylorthosilicate as the silicon source,tetrabutylorthotitanate as the titanium source,and incorporating straight chain alkanes as swelling agents.

The adsorption behavior of dodecylamine on carbon steel surface and its inhibition mechanism in hydrochloric acid solutions were studied by electrochemical methods,atomic force microscopy and contact angle measurements.
