Synthesis of Tri-Cationic Surfactants Containing Three Positive Nitrogen Atoms Acting as Corrosion Inhibitors in Acidic Medium

Öz

One of the important problems of many branches of industry is corrosion. Especially in the metal industry, it deforms the metal surface, thereby causing it to lose its metallic properties. Against this adverse effect of corrosion, in this study, tri-cationic surfactant containing three positive groups in its structure was synthesized in order to prevent metal corrosion occurring in 1.0 M HCl medium. After their structures were elucidated by spectroscopic methods (IR and NMR), the corrosion inhibition activities of these compounds in acidic corrosive medium were investigated by weight loss method. For this, metal coupons are immersed in corrosive solutions containing different concentrations of inhibitor for 24 hours at room temperature. As a result of the corrosion tests conducted, it has been determined that the synthesized surfactants are very effective against the corrosion of low carbon steel in acidic environment. In order to associate with the corrosion inhibition mechanism, the physicochemical parameters of the synthesized tri-cationic surfactants such as critical micelle concentration, surface tension, micelle formation free energy were calculated. In addition, images of the metal surface were taken with a scanning electron microscope (SEM) to support it protects the metal surface against corrosion.

Asidik Ortamda Korozyon İnhibitörü Görevi Üstlenen Üç Pozitif Azot Atomu İçeren Tri-Katyonik Yüzey Aktif Maddelerin Sentezi

Öz

Birçok endüstri dalının önemli sorunlarından birisi korozyondur. Özellikle metal endüstrisinde, metal yüzeyini deforme eder ve böylece metalik özelliklerinin kaybolmasına yol açar. Korozyonun bu olumsuz etkisine karşı, bu çalışmada, 1.0 M HCl ortamında meydana gelen metal korozyonunu önlemek için yapısında üç pozitif grup içeren tri-katyonik yüzey aktif maddeler sentezlenmiştir. Yapıları spektroskopik yöntemler (IR ve NMR) ile aydınlatıldıktan sonra bu bileşiklerin asidik korozif ortamda korozyon inhibisyon etkinlikleri kütle kaybı yöntemiyle incelenmiştir. Bunun için değişik konsantrasyonlarda inhibitör içeren korozif çözeltilere metal kuponlar oda sıcaklığında 24 saat süre ile daldırılmıştır. Yapılan korozyon testleri sonucu, sentezlenen yüzey aktif maddelerin düşük karbon çeliğinin asidik ortamdaki korozyonuna karşı çok etkin oldukları tespit edilmiştir. Korozyon inhibisyon mekanizması ile ilişkilendirmek için, sentezlenen tri-katyonik yüzey aktif maddelerin, kritik misel konsantrasyonu, yüzey gerilimi, misel oluşum serbest enerjisi gibi fizikokimyasal parametreleri hesaplanmıştır. Ayrıca, metal yüzeyini korozyona karşı koruduğunu desteklemek adına taramalı elektron mikroskobu (SEM) ile metal yüzeyi görüntüleri alınmıştır.
