초록
윤활유 첨가제 중간체로서 Alkenyl Succinic Anhydride (ASA)계열인 i-(2',5'-diketotetrahydrofuranyl)octadacenyl acid (OSA)를 oleic acid (OA)와 maleic anhydride (MA)의 ene-reaction을 통하여 합성하였다. 이 반응의 진행과정은 GC분석을 통해 관찰함으로써 확인하였다. 숙신이미드 화합물은 알킬아민과 OSA와의 반응에 의해 합성되었다. 이 숙신이미드 화합물들은 윤활유 첨가제로서 항유화성, 내마모성, 방청성능 등을 시험하였으며, 이때 상대적으로 긴 알킬사슬을 가진 octadecylamine 유도체가 우수한 물성을 나타내었다.
i-(2',5'-Diketotetrahydrofuranyl)octadecenyl acid (OSA), an intermediate for the lubricating oil additive, was prepared by the ene-reaction of oleic acid with maleic anhydride. The reaction progress was monitored by gas chromatography by analyzing the amount of OSA. The series of succinimidyl compounds were synthesized by the reaction of alkyl amines and OSA. As a kind of lubricant additives, demulsibility, anti-wear, and anti-corrosion properties of these succinimidyl compounds were measured. The derivative of octadecylamine which has relatively long-chained alkyl group has showed good properties.
