With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

This nonmutagenic amino compound 4 (via the investigation into Salmonella/mammalian microsome assay) was also employed as diazo moiety coupling with acet-J-acid to form a diazo acid dye 5. The new dye 5 can color wool at 2% or silk at 3% o. w. f. into black one. The investigation of the uptake of 5 and its color appearance showed that it was assigned to an acid bluish black dye and its blackness was more excellent than that of Acid Black 10B.
经过Salmonella/mammalian microsome assay测试,4表现为非诱变性,用4与乙醯J-酸作用得到新型双偶氮酸性染料(5)。5对羊毛和丝绸分别在2%与3%色度下浸染都得到黑色染样,考察了5的上染曲线,并对染样进行了测色研究,发现该染料属於酸性蓝黑染料,其黑度优於目前市场上流行的酸性黑10B。
