I-Pyrogallol

Incazelo emfushane:

Isingeniso: I-Pyrogallol

kuyinto ebonakalayo yamakhemikhali e-reagent kanye namakhemikhali asetshenziswa kaningi. Ikhiqizwa ngendlela eyaqala ukulungiswa nguScheele (1786): ukushisa i-gallic acid. Njengamanje i-gallic acid itholakala nge-tannin. Ukushisa kukhuthaza i-decarboxylation。 Kusetshenziswa kakhulu ekwenziweni kwemithi, odayi, ukudla, izibulala-zinambuzane nemikhiqizo kagesi

iconImininingwane

Ku- kulayini nemboni kazwelonke ejwayelekile LY-T 2862; ngokuhambisana ne-US "amazinga we-reagent chemical"; Uhlobo lweLawson V kanye nemininingwane ejwayelekile yaseJapan ejwayelekile ye-K8780.

iconIsici

Iphuzu lokuncibilika ngu-131 134 ℃, iphoyinti elibilayo lingu-309 ℃, ukuminyana kwesihlobo kungu-1.46. I-UVλubuningi2. 88nm lapho i-pH = 5.4 emanzini. Iyancibilika emanzini, utshwala, i-ether, incibilike kancane ku-benzene, i-chloroform ne-carbon disulfide.

iconIsitoreji

Gwema umswakama nokukhanya, kuvalwe ngokuqinile, akukho ukuxhumana nensimbi.

iconUkupakisha

Umkhiqizo ugcwele emigqonyeni yamakhadibhodi enesisindo senetha esingu-25 kg emgqonyeni ngamunye.

iconIsicelo

1. Izithasiselo zezimonyo

2. Izithako ezibalulekile nezithasiselo embonini yamakhemikhali

3. I-ejenti yokunciphisa okunamandla ne-fungicidal kwezokwelapha

4. Enye yezindlela ezibalulekile zokuphakelayo

5. Isibulali zinambuzane esisebenza kahle kakhulu futhi esiphansi

6.New imaging materials, metallurgical flotation ejenti
