本研究は、非食用植物油であるカロフィルム・イノフィルム（ニヤンプルン）油をグリーン潤滑油として評価し、二段階エステル交換とトリメチロールプロパンを用いたエステル化により特性を改善。引火点212℃、流動点8℃、動粘度38.3 cStなど工業規格を満たし、酸価や過酸化物価の低減により化学的安定性も向上。FTIRとGC-MSでエステル基と脂肪酸バランスを確認し、再生可能潤滑油としての可能性を示した。
English
This study evaluates Calophyllum Inophyllum (nyamplung) oil as a green lubricant. Through two-step transesterification and esterification with TMP, the oil achieves industrial standards: flash point 212°C, pour point 8°C, kinematic viscosity 38.3 cSt, and improved chemical stability (acid value reduced from 36.5 to 1.62 mg KOH/g). FTIR and GC-MS confirm ester formation and balanced fatty acids. The modified oil shows potential as a renewable alternative to mineral lubricants.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではバイオマス由来潤滑油の需要が高まっているが、本研究成果は非食用油からの工業規格適合潤滑油の可能性を示しており、国産バイオ潤滑油開発の参考になる。ただし、実用化には酸化安定性などさらなる改善が必要。
In the global GX context
Globally, bio-based lubricants reduce dependence on petroleum. This paper demonstrates a viable processing route for non-edible vegetable oil to meet industrial lubricant standards. While not directly tied to climate disclosure, it contributes to the circular bioeconomy and renewable materials substitution, relevant for Scope 3 upstream emissions reduction strategies.
👥 読者別の含意
🔬研究者:Provides a chemical processing method and performance data for bio-lubricant production from Calophyllum Inophyllum oil.
🏢実務担当者:May inform R&D teams in lubricant manufacturing about renewable alternatives, but lacks economic and scalability analysis.
📄 Abstract（原文）
Calophyllum Inophyllum (nyamplung) Oil is recognized as a promising non-edible vegetable oil for the development of sustainable green energy lubricants. This study aims to improve the physicochemical characteristics of nyamplung oil through a two-step transesterification followed by esterification using trimethylolpropane (TMP), and to assess its tribological performance. The refined oil exhibited a flash point of 212 °C (ASTM D92) and a pour point of 8 °C (ASTM D97), indicating excellent thermal and flow stability. The kinematic viscosity was 38.3 cSt (ASTM D445) and the density 0.88 g/cm³ (ASTM D4052), both within industrial lubricant standards. The acid value decreased markedly from 36.5 to 1.62 mg KOH/g, while the iodine value (0.006 g I₂/100 g) and peroxide value (0.23 Meq/kg) demonstrated chemical stability. FTIR analysis confirmed the formation of ester functional groups, and GC–MS results showed a balanced distribution of saturated and unsaturated fatty acids. Overall, the modified Calophyllum Inophyllum Oil fulfills key technical criteria for eco-friendly green energy lubricants and shows strong potential as a renewable alternative to conventional mineral-based lubricants in industrial applications. Nevertheless, its crude form presents several drawbacks, including high acid and peroxide values as well as poor oxidative stability.
