摘要
选用合适的复合酰化体系,通过电位滴定,测定了工业碱木质素及其改性树脂的羟值。该方法简便快捷,精确性及重复性较好,易于实际应用。
Hydroxyl values of straw alkali lignin and modified lignin resin were determined by potentiometric titration in suitable composite aeylation system. This kind of assay is a simple, quick and precise method with good repetition. It is also easy for practical use.
