The mean activity coefficients of sodium salts of 1-amino-4-alkylaminoanthraquinone-2-sulfonic acid (alk= Me(MAS), Et, n-Pr, or n-Bu (n-BAS)) in aqueous solutions ranging in concentration from 10−3 to 10−2 mol kg−1 have been determined by means of isopiestic measurements at 50 and 60 °C respectively. It has been found that the mean activity coefficients of these dyes are much smaller than unity, the
1-氨基-4-烷基氨基蒽醌-2-磺酸钠盐(alk= Me(MAS), Et, n-Pr, or n-Bu (n-BAS))在不同浓度水溶液中的平均活性系数从 10-3 到 10-2 mol kg-1 已分别通过等压测量在 50 和 60 °C 下确定。已经发现这些染料的平均活性系数远小于1,MAS的系数最大,而n-BAS的系数最小。已经发现这些系数随着染料浓度的增加而降低。对 Miliceivic 处理获得的结果的检查表明,在 60 °C 时,MAS 以二聚体或三聚体形式存在,而其他染料以四聚体形式存在。
