| 中文摘要: |
| 分别以浓硫酸和氢氧化钠为催化剂,以蓖麻油和甲醇为原料制备了生物柴油样品,并对其进行了减压蒸馏.用气-质联用仪对蒸馏样品进行了分析.结果表明:由蓖麻油制得的生物柴油主要成分为蓖麻酸甲酯,还含有少量油酸甲酯、亚油酸甲酯、十六酸甲酯及十八酸甲酯等成分;当减压蒸馏的液相温度较高、升温速率较慢时,少部分蓖麻酸甲酯将分解为10-十一烯酸甲酯和庚醛;当减压蒸馏的生物柴油样品含硫酸催化剂时,大部分蓖麻酸甲酯将发生脱水反应生成亚油酸甲酯. |
| 英文摘要: |
| Biodiesel samples were made from castor seed oil and methanol using concentrated sulfuric acid and sodium hydroxide as a catalyst respectively,and vacuum distillation of biodiesel samples were carried out.Distillated samples were analyzed by GC/MS.The results showed that main components of the biodiesel from castor seed oil were methyl ricinoleate,in addition,there were still a spot of methyl oleate,methyl linoleate,methyl hexadecanoate and methyl octadecanoate.When the temperature of liquid phase was highe... |
