한국산 토탄의 성상(분자량, 분자식 및 시성식)과 기응용(전답용 토양개량제 및 액성인질 비료구조)에 관해서 이미 연구보한 바가 있으나, 흄산의 구조를 추정하는데 있어서, 미흡한 점이 있어서, 이의 보완책으로서 aromatic diazonium salt를 coupling 시켜, phenolic-OH group 의 결합상태를 살펴보고 각종 aromatic diazonium salt와 흄산 및 니트로흄산에 의해서 얻어진 생성물들을 Azo 염료로 이용함으로서 응용책의 일환을 강구했다.

The coupling of aromatic diazonium salts with humic or nitrohumic acid, as a supplemental method of determining the structure and utilization of humic acid, were studied. The following results were obtained. 1) Humic acids have many vacan to-and p-positions in their phenol kernels. 2) Humic acids have not so many benzene kernels in their structure units. 3) When coupled with aromatic diazonium salts (such as aniline, aminonaphthalene and aminoanthraquinone derivatives), various azo-dye were obtained.
