摘要
从菽麻种子里分离出一种半乳甘露多糖,mp.285℃,[a]_D^(25)+43.5,半乳糖和甘露糖的克分子比为1:2.3。该多糖和它的羧甲基衍生物与 Na_2B_4O_7KAl(SO_4)_2交联成冻胶,用作石油工业水基冻胶压裂液的原料。
The isolated galaetomannan from the seeds of Crotlaria juncea L.have mp.285℃,[a]_D^(25)+43.5°.The molicule ratio between galactose and mannose is 1:2.3 in the galactomannan The polysaccharide and his carboxymets hyl derivate can connet with Na_2B_4O_7 or KAI (SO_4)_2 to form gel.It is used in the petroleum industry for the sources of the hydraulic fracturs ing of hydrogel.
