共轭效应;
The hydrolysis of chitin under concentrated alkali conditions would produce double anion because of conjugative effect and steric effect ( producing primary amine which had positive ion properties and linear chain macromolecular structure and which has good flocculability and clarification performance).
因共轭效应和空间效应,甲壳质在浓碱条件下水解,能形成双负离子,形成具阳离子性质的伯胺和具有直链高分子结构,具有优良的絮凝性能和澄清作用。
When they both can produce conjugative effect, they have the reaction characteristic of conjugated diene.
当两者可生成共轭体系时,应具有共轭二烯烃的反应特性。
