    摘要:
    由于长烷基链在亲水性和水溶性方面的固有缺陷,烷基α - D-木糖苷( 7 )作为糖基表面活性剂几乎没有实际应用,需要进行改造以获得烷基二氧乙基α - D-木糖苷( 5 )以二氧乙烯片段(-(OCH 2 CH 2 ) 2 -))作为亲水间隔基以增加相关的TPSA值。以D-木糖为原料,立体选择性合成了1,2-顺式烷基二氧乙基α - D-木糖苷(5a-5f ,n=6-12)。研究了它们的物理化学性质,包括水溶性、表面张力、发泡性、乳化性、热致液晶性和吸湿性。随着烷基链长度 (n)的增加,它们的水溶性逐渐降低,而计算出的HLB值为 14.72 → 11.67 (n = 6 → 12)。十二烷基二氧乙基α - D-木糖苷( 5f )由于HLB值低而不具有水溶性。此外,它们的CMC值随着烷基链长度的增加而降低,其中癸基二氧乙基α - D-木糖苷( 5e )的CMC值低至9.21×10 -5  mol·L
