Pyrogallol CAS 87-66-1 me ka maemae 99% no ka lauoho lauoho
ʻO Pyrogallol CAS 87-66-1 he keʻokeʻo keʻokeʻo ʻala ʻole. ʻona ʻawaʻawa. ʻO ka ʻike ʻana i ka ea a me ka mālamalama e hina hina. E wela mālie a hoʻomaka i ka sublimate. ʻO ka helu heheʻe 133-134 ℃, kahi e hoʻolapalapa ai 309 ℃, ka mānoanoa pili 1.453, ʻōlelo kuhikuhi refractive 1.561. Hiki ke hoʻoheheʻe ʻia i ka wai, ethanol, etera, hiki ke hoʻoheheʻe ʻia i loko o benzene, chloroform, carbon disulfide. Ke ʻike ʻia i ka ea, ʻeleʻele ka waihoʻoluʻu o ka hoʻonā wai, ʻoiai ʻoi aku ka wikiwiki o ke kala o kāna hopena caustic.

1. Hoʻohana ʻia ʻo Pyrogallol no ka hoʻomākaukau ʻana i ka solution colloidal metala, kala i ka ʻili, ka hoʻoluʻu ʻana a me ka etching fur, lauoho, etc. Hiki ke hoʻohana ʻia ʻo Pyrogallol ma ke ʻano he mea hoʻomohala kiʻiʻoniʻoni, kahi thermosensitive kiʻi infrared, kahi mea pale polymerization o ka styrene a me ka polystyrene, kahi mea waena o ka lāʻau lapaʻau a me nā mea pena, a me kahi reagent analytical.
2. Hoʻohana nui ʻia ʻo Pyrogallol i ka hana ʻana o ka mea hoʻomohala, polymerization inhibitor a me ka thermosensitive kiʻi infrared. Hoʻohana pū ʻia ʻo Pyrogallol ma ke ʻano he waena o nā lāʻau lapaʻau a me nā mea hoʻonaninani
3. Hoʻohana ʻia ʻo Pyrogallol ma ke ʻano he analytical reagent, reductant a me ka mea hoʻomohala
4. Hoʻohana ʻia ʻo Pyrogallol no ka nānā ʻana a me ka hoʻoholo ʻana i ka oxygen, antimony, bismuth, cerium, iron, molybdenum, tantalum a me niobium; Hoʻohana ʻia e hoʻomohu i ka oxygen i ka ʻike kinoea; Hoʻohana ʻia no ka hopena kala o ka nitrite, molybdenum, niobium, titanium, cerium, bismuth, keleawe, vanadium, hao, iodate, etc.
5. Metal complexing agent.Gravimetric hoʻoholo o bismuth a me ka antimony. ʻO nā reductants o ke gula, ke kālā, nā paʻakai mercury, ka waikawa phosphomolybdic a me ka waikawa phosphotungstic, i hoʻohana ʻia e komo i ka oxygen i ka loiloi kinoea.
20kgs / ʻeke, 25kgs / pahu, 200kg / pahu a i ʻole koi o nā mea kūʻai aku. E mālama iā ia mai ka mālamalama ma kahi mahana ma lalo o 25 ℃.
