    摘要:
    当前在技术上使用微藻的努力集中在产生具有与原油基产品相同的分子结构的燃料。在这里,我们通过将藻类油脂肪酸的独特分子结构转化为价值更高的化学中间体和材料,提出了一种利用藻类的不同方法。获得了来自微藻的粗提取物,即硅藻硅藻(Phaeodactylum tricornutum),其为包含不饱和脂肪酸(16:1、18:1和20:5)磷酸胆碱甘油三酸酯的多组分混合物。使用已知的催化剂前体[{1,2-(t Bu 2 PCH 2)2 C 6 H 4将该粗藻油暴露于CO和甲醇中} Pd(OTf)](OTf)导致不饱和脂肪酸异构化/甲氧基羰基化为高纯度(> 99%)的线性1,17-和1,19-二酯的混合物。与相应二醇的混合物进行缩聚反应,得到了一种新型的混合聚酯-17 / 19.17 / 19,其熔融和结晶温度高。
