Pyrogallol

Kufotokozera Kwachidule:

Chiyambi: Pyrogallol

ndi mankhwala reagent ndi mankhwala zopangira ndi ntchito angapo.Amapangidwa monga momwe adakonzera koyamba ndi Scheele (1786): kutenthetsa gallic acid.Pakalipano gallic acid imachokera ku tannin.Kutentha kumapangitsa decarboxylation .Amagwiritsidwa ntchito kwambiri popanga mankhwala, utoto, zakudya, mankhwala ophera tizilombo ndi zinthu zamagetsi.

Maonekedwe:White crystalline ufa

Dzina la Chemical:Benzene-1,2,3-triol

Mayina ena:1,2,3-Trihydroxybenzene, Pyrogallic acid

Molecular formula:C6H3(OH)3

Kulemera kwa mamolekyu: 126.11

Malo osungunuka:309 °C

Nambala ya CAS:87-66-1

Katundu:Izi ndi ufa woyera wonyezimira wa crystalline, wosungunuka m'madera awiri a madzi, 1 gawo la ethanol kapena 2 mbali za ether.

Zofotokozera

Inmogwirizana ndi muyezo makampani dziko LY-T 2862;mogwirizana ndi US "chemical reagent miyezo";Mtundu wa Lawson V ndi mtundu wa Japan wa K8780 reagent.

Mbali

Malo osungunuka ndi 131～134 ℃, malo otentha ndi 309 ℃, kachulukidwe wachibale ndi 1.46.UVλ_max2. 88nm pamene pH = 5.4 m'madzi.Kusungunuka m'madzi, mowa, ether, kusungunuka pang'ono mu benzene, chloroform ndi carbon disulfide.

Kusungirako

Pewani chinyezi ndi kuwala, kusindikizidwa mwamphamvu, osakhudzana ndi zitsulo.

Kulongedza

Zogulitsazo zimadzaza mu ng'oma za makatoni zolemera 25 kg pa mbiya.

Kugwiritsa ntchito

1. Zodzikongoletsera zowonjezera

2. Zothandizira zofunikira komanso zowonjezera pamakampani opanga mankhwala

3. Wamphamvu kuchepetsa wothandizira ndi fungicidal mankhwala

4. Chimodzi mwazinthu zofunika kwambiri pazakudya

5. Mankhwala othandiza kwambiri komanso otsika otsalira

6. Zida zatsopano zojambulira, wothandizila zitsulo zoyandama
