    摘要:

    蔗糖和油酸甲酯為原料,，采用無溶劑兩步法合成蔗糖多酯,，應(yīng)用響應(yīng)面分析法對(duì)蔗糖多酯合成工藝條件進(jìn)行優(yōu)化,。得出最佳合成條件為：反應(yīng)物摩爾比11.79、催化劑用量2.06g,、反應(yīng)溫度138.06℃,、反應(yīng)時(shí)間5.80h,，在此條件下合成蔗糖多酯的產(chǎn)率為

    Abstract:

    97.2%,。 Disaccharides and long chain fatty acids are used as raw materials to directional and controllable synthesize emulsifier, which is one of routes of effectively using low-value agricultural raw materials. Its realization methods include the enzyme method, the physical-assisted method and chemical synthesis method. Sucrose polyester was synthesized with methyl oleate and sucrose. The optimum reaction conditions are: methyl oleate/sucrose=10 (mol/mol); catalyzer is 2.06g; reaction temperature is 138.06℃; reaction time is 5.80h. The product yield reached 97.2%. The result indicated that synthesis of sucrose polyester by two-step method has high-yield.
