Tsananguro Pfupi:

Nhanganyaya: Pyrogallol

kemikari reagent uye kemikari mbishi zvinhu zvine mashandisiro akawanda. Iyo inogadzirwa nenzira iyo yakatanga kugadzirirwa naScheele (1786): kudziyisa gallic acid. Parizvino gallic acid inowanikwa kubva kumatanini. Kuchenesa kunokonzera decarboxylation。 Inoshandiswa zvakanyanya mukugadzira mishonga, dhayi, chikafu, mishonga yekuuraya zvipuka uye zvigadzirwa zvemagetsi

iconMagadzirirwo

In mutsetse neyakaganhurirwa indasitiri yenyika LY-T 2862; zvinoenderana neUS "makemikari reagent zviyero"; Lawson V vhezheni uye yeJapan yenyika yakajairwa K8780 reagent yakatarwa.

iconFeature

Nzvimbo yekunyungudika ndeye 131 134 ℃, nzvimbo yekubikira iri 309 ℃, huwandu hwehukama i1.46. UVλmax2. 88nm apo pH = 5.4 mumvura. Inonyungudika mumvura, doro, ether, yakanyungudika zvishoma mu benzene, chloroform uye kabhoni disulfide.

iconKuchengetedza

Dzivisa hunyoro uye mwenje, yakavharirwa zvine simba, kusabatana nesimbi.

iconKurongedza

Chigadzirwa chakazara mumakadhibhodhi madhiramu ane huremu huremu hwe25 kg pahomwe.

iconKushanda

1. Zvizoro zvekuwedzera

2. Zvinokosha catalysts uye zvinowedzera mumakemikari indasitiri

3. Yakasimba yekudzora mumiririri uye fungicidal mumushonga

4. Imwe yemafomula akakosha ezvikafu

5. Mishonga inouraya zvipembenene yakanyanya kushanda uye yakaderera

6. Zvinyorwa zvitsva zvekufungidzira, metallurgical flotation mumiriri
