Optimizacija metode za testiranje korozivnosti hlapnih organskih spojin

Ocepek, Jan (author), Strlič, Matija (mentor)

V diplomski nalogi sem optimiziral metodo za testiranje vpliva izbranih hlapnih organskih snovi (HOS) na korozijo bakra in svinca. Osredotočil sem se na vpliv koncentracije HOS in vpliv volumna reakcijske posode. Pri testiranju sem uporabil etanojsko kislino, ki sodi med najbolj korozivne HOS v notranjem prostoru, in pentanal, s pomočjo katerega lahko predvidimo vpliv aldehidov na korozijo. Z rezultati testov za etanojsko kislino in pentanal sem predvidel vpliv mešanic HOS na korozijo. Sestavo mešanic HOS, ki jih uporabljamo za odišavljanje prostorov, sem analiziral s plinsko kromatografijo.

• Title: Optimization of Corrosion Test Methods for Volatile Organic Compounds

Abstract

In my thesis, I optimized the testing method for the impact of volatile organic compounds (VOCs) on the corrosion of copper and lead. I focused on the impact of the concentration of VOCs and the impact of the volume of the reaction vessel. During the testing, I used acetic acid which is one of the most corrosive VOS indoors, and pentanal which enables the prediction of aldehydes' impact on corrosion. With the results of the tests for acetic acid and pentanal, I predicted the impact of VOCs mixtures on corrosion. Using gas chromatography I analyzed the compositions of VOCs mixtures used for scenting spaces.
