  非邻位脂肪族二醇的生物催化合成

  摘要：

  在细胞色素P450单加氧酶（CYP450s）和相关的过加氧酶的C–H键选择性加氧官能化领域，生物催化剂受到了越来越多的关注，并引领了该领域。在这里我们报告CYP505A30的底物滥交，以前被表征为脂肪酸羟化酶。除了饱和脂肪酸的区域选择性氧官能化（ω-1–ω-3羟基化）以外，伯脂肪醇也具有相似的区域选择性。此外，烷烃如正辛烷和正癸烷也容易被接受，从而允许通过顺序的氧合产生非邻位二醇。

  Principal solvents, especially mono-ol and diol principal solvents, having a ClogP of from about 0.15 to about 0.64, preferably from about 0.25 to about 0.62, and more preferably from about 0.40 to about 0.60, are disclosed that have the ability to make clear aqueous fabric softener compositions containing relatively high concentrations of fabric softener actives having ester linkages in their long, hydrophobic chains. The fabric softener actives are either unsaturated, or have intermediate length chains (˜C 12-14 ) and the said principal solvents are used at levels of less than about 40%. Other solvents may be present. Some of the said principal solvents are novel compounds and/or novel mixtures. Premixes of the fabric softening actives, the principal solvents, and, optionally, other solvents are useful in the preparation of complete formulations by obviating/limiting the need for heating.

  Coating compositions that provide hydrophilic and self-cleaning properties upon exposure to an electromagnetic spectrum are disclosed. Coatings can include lignin-coumarate derivatives and/or lignin-azobenzene derivatives. When exposed to the electromagnetic spectrum, these compounds isomerize to cis-configuration which are hydrophilic in nature as compared to when these compounds are in their hydrophobic trans-state.
