A novel polyurethanes from epoxidized soybean oil synthesized by ring opening with bifunctional compounds

Karadeniz, Kemal; Yakup Calokoglu; Mustafa Yasin Sen (SPRINGER, 2017)

The present work reports the first synthesis of biobased polyurethanes utilizing soy-based polyols that are synthesized by epoxy ring opening of epoxidized soybean oil with chemicals bearing two different functionalities. ...
Investigation of Plasticizer Effect of Hazelnut Oil and its Epoxidized Derivative on Chloroprene and Nitrile Rubbers

Karadeniz, Kemal (DR ALFRED HUTHIG VERLAG GMBH, 2012)

In this study, the use of hazelnut oil (HaO) and epoxidized hazelnut oil (EHaO) as plasticizers in acrylonitrile butadiene rubber (NBR) and polychloroprene rubber (CR) was investigated. Tensile properties, glass transition ...
Oil and Freeze Resistant Performance of Rubber Compounds with Non-Carcinogenic Plasticizers

Karadeniz, Kemal (DR ALFRED HUTHIG VERLAG GMBH, 2011)

In this study, oil and freeze resistant performance of rubber compounds with non-carcinogenic (phthalate-free) plasticizer were investigated. Acrylonitrile-butadiene copolymer (NBR), polychloroprene rubber (CR), styrene-butadiene ...
Ring Opening of Epoxidized Soybean Oil with Compounds Containing Two Different Functional Groups

Karadeniz, Kemal; Hatice Aki; Mustafa Yasin Sen; Yakup Calikoglu (WILEY, 2015)

bearing two different functional groups simultaneously. In this way, two new polyols were synthesized, one with TGA (polyol 1) and one with TGAME (polyol 2). FTIR and H-1- and C-13-NMR spectroscopy confirmed that the ring ...
Synthesis of Nano-Silica with Cyclohexylamine and Investigation of the Reinforcement Effect on different Rubber Types

Karadeniz, Kemal (DR ALFRED HUTHIG VERLAG GMBH, 2014)

In this study, nano-scaled silica was prepared by hydrolysis and condensation reactions of tetraethyl orthosilicate (TEOS) in presence of cyclohexylamine (CHA) as catalyst. Surface treatment of the nano-particles was carried ...
Vic-Dioxime Complexes Bearing Carboxyester and Picolyl Amide Functionality: Synthesis, Characterization, Spectroscopy and Electrochemistry, Monatshefte Fur Chemie.

Karadeniz, Kemal; Kandaz, Mehmet; Yaraşır, Meryem Nilüfer (2013)
Vic-dioxime complexes bearing carboxyester and picolyl amide functionality: synthesis, characterization, spectroscopy, electrochemistry, and electrical properties

Yaraşır, Meryem Nilüfer; Kandaz, Mehmet; Karadeniz, Kemal (SPRINGER WIEN, 2013)

We have synthesized a vic-dioxime, [(1Z,2Z)-bis(2-oxo-2-(pyridin-2-ylmethylamino)ethyl)-N'1,N'2-dihydroxyethanebis(imidothioate)] (LH4) via dimethyl 2,2'-(1,2-bis(hydroxyimino)ethane-1,2-diyl)bis(sulfanediyl)diacetate (LH2) ...
