| 中文摘要: |
| 为探究环境友好型高效催化剂原位催化小球藻制备生物柴油，采用5种氨基酸（甘氨酸、天冬氨酸、L-谷氨酸、L-赖氨酸、L-脯氨酸）分别与盐酸和氢氧化钾反应合成氨基酸离子液体，以氨基酸离子液体为提取剂和催化剂，对小球藻进行原位催化制备生物柴油，并采用单因素实验对反应条件进行优化。结果表明：L-脯氨酸与盐酸反应合成的氨基酸离子液体（\[L-Pro\]\[Cl\]）具有更好的生物柴油提取率和催化率；小球藻生物柴油的最优制备条件是\[L-Pro\]\[Cl\]用量100%（以小球藻藻粉质量计）、甲醇与藻粉质量比11∶ 1、反应温度65 ℃、反应时间18 h，在此条件下小球藻生物柴油的提取率为83.16%，催化率为64.54%。综上，氨基酸离子液体\[L-Pro\]\[Cl\]适合用于原位催化小球藻制备生物柴油。 |
| 英文摘要: |
| To explore the in-situ catalytic preparation of biodiesel from Chlorella using environmentally friendly and efficient catalysts, amino acid ionic liquids were synthesized by reacting five amino acids (glycine, aspartic acid, L-glutamic acid, L-lysine and L-proline) with hydrochloric acid and potassium hydroxide, respectively. The amino acid ionic liquids were used as extraction agents and catalysts for the in-situ catalytic preparation of biodiesel from Chlorella. The reaction conditions were optimized using single factor experiments. The results showed that the amino acid ionic liquid \[L-Pro\]\[Cl\] synthesized by the reaction of L-proline with hydrochloric acid had better biodiesel extraction rate and catalysis rate. The optimal preparation conditions for Chlorella biodiesel were as follows: dosage of \[L-Pro\]\[Cl\] 100%(based on the mass of Chlorella powder), mass ratio of methanol to Chlorella powder 11∶ 1, reaction temperature 65 ℃, and reaction time 18 h. Under these conditions, the extraction rate of biodiesel was 83.16%, and the catalysis rate was 64.54%. In summary, the amino acid ionic liquid \[L-Pro\]\[Cl\] is suitable for in-situ catalytic preparation of biodiesel from Chlorella. |
