This study focuses on the synthesis and application of glycerol carbonate (GC) as an emulsifier for light crude oil. GC was synthesized from glycerol and dimethyl carbonate via transesterification, achieving a 90% yield. Characterization through H-NMR, C-NMR, and FT-IR confirmed its structure. The emulsification properties of GC were tested by mixing it with light crude oil and water, demonstrating effective emulsification and forming stable emulsions. Stability tests with GC concentrations of 60/40, 70/30, and 80/20 revealed that emulsions remained stable for over 24 h. A particle size analysis indicated that higher GC concentrations produced smaller droplet sizes, enhancing the emulsification efficiency. This study highlights the potential applications of GC in oil spill remediation and enhanced oil recovery, emphasizing its biodegradability and low toxicity as environmental benefits. Overall, GC is presented as an effective and eco-friendly emulsifier for light crude oil, offering stable emulsions and promising industrial applications.
本研究聚焦于碳酸甘油酯（GC）作为轻质原油乳化剂的合成与应用。GC通过甘油与碳酸二甲酯经酯交换反应合成，产率达90%。通过氢核磁共振（H-NMR）、碳核磁共振（C-NMR）和傅里叶变换红外光谱（FT-IR）对其进行表征，证实了其结构。将GC与轻质原油和水混合测试其乳化性能，结果表明其具有有效的乳化作用并形成了稳定的乳液。对GC浓度为60/40、70/30和80/20的乳液进行稳定性测试，结果显示乳液在24小时以上保持稳定。粒度分析表明，较高的GC浓度会产生更小的液滴尺寸，提高了乳化效率。本研究突出了GC在溢油修复和提高原油采收率方面的潜在应用，强调了其生物降解性和低毒性等环境优势。总体而言，GC被证明是一种用于轻质原油的有效且环保的乳化剂，能提供稳定的乳液并具有广阔的工业应用前景。
