'amoniuma persulfate: hoʻololi kemikala a me ka mea hiki nui

'amoniuma persulfate ua hoʻohana 'io? i ka polymerization kaʻina hana, e like me ka Punk i ka makaukau ana o rubbers, Ka lula ea Ke a me latex, ma ka For the, ma ka etching o pai huakai kaapuni papa. Keia mea ua i kekahi manawa hoʻohana no ka disinfection a me ka loloʻa.

'amoniuma persulfate: Physico-Nine Inch waiwai

Himreaktiv ho colorless papa, i kekahi manawa, me he omaomao iki hue. Iki wailana ma H 2 O (42.7%) i ka wela o ka 15,5 ° C. Ma paio hahana maoli nō ma luna o 120 degere pirosernisty'amoniuma ano, oiai o oxygen ua hookuu. It E e kaulana ua maloo ka paʻakai hiki waiho wahoʻaneʻane loa, oiai ka wai paakai ua hoʻomaka koke hydrolyzed me ka hoʻokuʻu o ka o oxygen a me ka naikokene. Koʻana koko pāʻoihana o ka hui hoʻomaka e hydrolyze, a hiki ma ka lumi ana wela, i ka wa a ka mehana o ka disintegration kaʻina ua hoʻokāʻoi '. I mea e 'ūlōlohi i ka decomposition, i koʻana koko pāʻoihana o'amoniuma persulfate i hoʻohuiʻia potasiuma alum paha sulfates o ka mekala' åkilikai ke hooheheeia.

'amoniuma persulfate: hoʻololi kemikala o

A mea kemikala pāʻoihana ua hoomakaukauia ma electrolysis o ka'amoniuma sulphate i loko o ka sulphateʻakika. E hana i kēia, lawe i kekahi kiaha 20 knm anawaena a me ka buke o nā lika elua ua nininiʻia ma loko o laila 1,7 hano o ka paʻa kūhohonu loa'amoniuma sulufahate pāʻoihana a me elima ka pono o ka sulphateʻakika. Next, ka mea kūpono ukuhiia i na hoopai ana e electrolysis ka hoʻohana nā uila aʻa lolo i ka platinum uea. Inā ma ka kaʻina hana o ka electrolysis hoʻomaka e honi i'amoniuma hydroxide, laila, hoʻokomo ekolu iʻelima ml o ka paʻa kūhohonu loa pāʻoihana o ke'amoniuma sulphate maʻakika sulufahate. Ma hope iho o kela mea keia ekolu i eha hora, a holoi iho la i akuʻikena nā uila aʻa lolo. Ma hope o 24 hola electrolysis i huiia 90 g. O ka pepe iho la ka'amoniuma sulufahate a me ka electrolysis hoomauia no kekahi 70 hola. Iloko o ka electrolysis pāʻoihana ua ho'āla mau. Ke kūpono nā pōaka o'amoniuma persulfate i hoʻokaʻawaleʻia, a me ka pāʻoihana ua hou paʻa kūhohonu loa me ka'amoniuma sulphate a me kaʻakika sulphate acidified. Ke kūpono precipitate ua maloʻo ma ka wela, aole oi aku mamua o 40 degere.

E like me ka rula, loaa e like me ka la hana o ko lakou hoomakaukau ana kekahi i oi aku mamua o 90%'amoniuma nadsernistogo, ka mea, ua pinepine hoʻohana me ka oxidant. A mea kemikala me ka lehulehu malalo o ka hana waiwai amenable i ka recrystallization. No ka mea, 700 g. O ka paʻakai mea hoʻoheheʻe i loko o ka'ālike buke o ka mehana ka wai (ma kahi o 40 ° C). Eia, hoʻohana 'ohe Kānana pepa, i ka hoao ana pāʻoihana ua wae', i kau ai i ka filtrate ua ho'ēmi. Ke kūpono nā pōaka i huikalaʻia'amoniuma persulfate i wae 'ia ma ka Buchner funnel, a holoiʻia me ka wai. Ka la hoomalolo loaa ka nui me ka palapala hōʻoia reagents q.s.p.

'amoniuma persulfate - Naita me ia a me ke ahi maopopo, akā, ka poʻea pau i ke'ā o nā waiwai. Ma ke kaʻina hana o ka umu ahi e keʻano ukiuki a me kaʻawahia waiwai aku. Ka hoʻomaopopoʻana mai la mea kemikala me combustible waiwai ua ole ae, e like me ka mea pili i ka oxidant ikaika, a reacts me combustible mea, e like me hoemi konohiki. Ma paio hahana maoli nō'amoniuma persulphate decomposes hoʻomaka koke, keia paha ke he wahi lihi iki o kaʻawahia, a corrosive kinoea (naikokene oxides, ammonia ka ohu, luaipele oxides). Ke degere o ka ole ma ka kanaka kino ia mea i kekahi o ka waiwai o ke kolu o ka papa o ka pilikia. I kā mākou tolerated mahele lāʻau i loko o ka hana pū nō ia kahi no ka'amoniuma persulfate mea 0,1 mg no cubic mika.

'amoniuma persulfate ho'āʻo i keʻano ukiuki o ia ma kaʻili, a mucous membranes o ka nasal, ku una lua, naehana'āpana, conjunctiva. Inhalation o ka waiwai hoʻonāukiukiʻana mai o ka ulu ana o asthmatic maʻi. I ka hoʻolōʻihiʻia ai ka puanaʻia ke ana dermatitis, eczema, pinepine pu ma allergic reactions, hoikeia mai me urticaria a me ka hawewe.

I ka hana ana me ka mea kemikala pono e hana i kekahiʻano o ka aiiay? Ieaoa (respirator, laholio goggles, nohona ma).
