Synthesis and rust preventing properties of dodecyl succinate derivatives containing triazole groups / Seung-Yeob Baek in Industrial & engineering chemistry research, Vol. 51 N° 28 (Juillet 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 28 (Juillet 2012) . - pp. 9669-9678 Titre : Synthesis and rust preventing properties of dodecyl succinate derivatives containing triazole groups Type de document : texte imprimé Auteurs : Seung-Yeob Baek, Auteur ; Young-Wun Kim, Auteur ; Seung Hyun Yoon, Auteur Année de publication : 2012 Article en page(s) : pp. 9669-9678 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Properties  Dodecyl  succinate  derivatives Résumé : Green corrosion inhibitors, n-dodecyl succinate derivatives containing one (HSE) or two triazole groups (DSE), were prepared by three step reactions, that is, nucleophilic substitution reaction, click coupling reaction, and esterification reaction. The characterization results obtained from 1H NMR, FT-IR, and elemental analysis indicated that the succinate derivatives were synthesized successfully. The rust preventing properties of the final products were also investigated using both ASTM D665 and weight loss methods. It was found that the strength of rust-preventing property due to the presence of succinate derivatives in paraffin oil was largely determined by the concentration of alkyl chains, not by their length or by the types of functional groups.

Synthesis of succinic acid alkyl half - ester derivatives with improved lubricity characteristics / Seung-Yeob Baek in Industrial & engineering chemistry research, Vol. 51 N° 9 (Mars 2012) 

Public ISBD [article]  in Industrial & engineering chemistry research > Vol. 51 N° 9 (Mars 2012) . - pp. 3564–3568 Titre : Synthesis of succinic acid alkyl half - ester derivatives with improved lubricity characteristics Type de document : texte imprimé Auteurs : Seung-Yeob Baek, Auteur ; Young-Wun Kim, Auteur ; Keunwoo Chung, Auteur Année de publication : 2012 Article en page(s) : pp. 3564–3568 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Succinic  acid  Lubricating  properties Résumé : A series of succinic acid alkyl half-esters were synthesized with higher than 97% yields by a one-step reaction of succinic anhydride with various fatty alcohols. The synthesized esters were soluble in 100N base oil at 1 wt %, and the lubricating properties of the esters in ultralow-sulfur diesel fuel were measured using a high-frequency reciprocating test rig and a four-ball wear machine. Wear scar diameter results showed that lubricity depended on the presence of a carboxylic acid group and that enhancements to lubricity depended strongly on the chain lengths of the alkyl group.
