摘要
以B型微晶淀粉为原料、正己醇为配体,采用非水溶剂法制备得到了V型直链淀粉-正己醇复合物。研究了反应温度、滴加时间和冷却温度等对V型复合物结晶度的影响。通过单因素及正交试验得到最佳工艺条件为:反应温度为70℃、滴加速率为2mL/min、室温冷却制备条件,此时所得到的V型复合物的结晶度为70.7%,且具有优异的结晶性。
By means of non-aqueous solvent,V-type amylose-hexanol complex which B-type microcrystalline starch made a combination with hexanol was prepared.Study the influence of the reaction temperature,dropping time and cooling temperature on the V-type complexes’ crystallinity.The optimal synthetic conditions were found through the single and orthogonal experiment as follows：reaction temperature at 70 ℃,dropping rate 2 mL/min,cooling to room temperature.V-type complex was prepared under optimum conditions,the crystallinity reached 72.07%.
