含不同水溶性基团的三聚氰氯衍生物的合成

Synthesis of 2,4,6-Trichloro-1,3,5-triazine Derivatives with Different Water-Soluble Groups

木质纤维素制备乙醇最关键的步骤是使纤维素水解成可发酵糖,但目前纤维素水解效率很低,是生物质能源化利用的瓶颈。依据活性染料染色纤维素类织物具有"活性脆损"的性质提出一种新思路——以化学改性的方法改变纤维素的结晶结构从而提高其水解效率。采用三聚氰氯与氨基丙酸、氨基乙磺酸中的-NH2发生亲核取代反应,制备含有不同水溶性基团的三聚氰氯衍生物作为木质纤维素化学改性的改性剂。通过红外光谱、高效液相色谱质谱联用、13C NMR谱对其进行结构验证。

The key of producing fuel ethanol with lignocellulose is how to hydrolyze cellulose into fermentable sugars efficiently,but the low yield of fermentable sugar in cellulose hydrolysis is the bottle-neck problem in biomass utilization. A creative idea was proposed that based on the cellulose fabric dyed reactive dyes owns the character of'reactive tendering',the yield of hydrolysis can be improved by the crystal structural change of cellulose based on chemical modification. 2,4,6-trichloro-1,3,5-triazine derivatives with different water-soluble groups were synthesized successfully through nucleophilic substitution reaction between cyanuric chloride and aminopropionic acid or aminoethanesulfonic acid. These 2,4,6-trichloro-1,3,5-triazine derivatives were used as modifiers and reacted with lignocellulose under chemical modification. The structure of the target products were determined by IR,HPLC / MS and13 C NMR spectrometer.
