Ammonium persulfate: kaphatikizidwe ndi kufunika othandiza

ammonium persulfate ntchito kwambiri njira polymerization, komanso condense pa yokonza rubbers, mapulasitiki ndi lalabala, kujambula, mu etching wa matabwa kusindikizidwa dera. Zinthu zimenezi nthawi zina amagwiritsidwa ntchito kwa disinfection ndi oyeretsa.

Ammonium persulfate: katundu Physico-mankhwala

Himreaktiv akuimira mbale colorless, nthawi zina azioneka Kamaoneka. Pang'ono sungunuka H 2 O (42.7%) pa kutentha kwa 15,5 ° C. Pa Kutentha pamwamba madigiri 120 mitundu pirosernisty ammonium, pamene mpweya adzamasulidwa. Tikumbukenso kuti mchere wouma akhoza kusungidwa pafupifupi kalekale, pamene mchere yonyowa mofulumira hydrolyzed ndi kumasulidwa mpweya ndi asafe. njira amadzimadzi pawiri anayamba hydrolyze, ngakhale firiji, pamene kutentha limatuluka ndondomeko azingokhala kumatheka. Pofuna msanga kuwonongeka, zothetsera amadzimadzi persulfate ammonium Chinawonjezeka alum potaziyamu kapena sulfates zitsulo soda.

Ammonium persulfate: kaphatikizidwe

A njira reagent zakonzedwa ndi electrolysis wa sulphate ammonium mu asidi sulphate. Kuti tichite zimenezi, kutenga mtsuko 20 cm awiri ndi buku la malita awiri udzathiridwa m'menemo 1.7 lita imodzi ya zimalimbikitsa njira ammonium sulphate ndi Botolo asanu asidi ndi sulphate. Kenako, osakaniza chifukwa chinaperekedwa kwa electrolysis ntchito maelekitirodi zopangidwa pulatinamu waya. Ngati m'kati electrolysis akuyamba pfungo la hydroxide ammonium, onjezerani ml ya zitatu mpaka zisanu njira zimalimbikitsa wa sulphate ammonium mu sulphate acid. Pambuyo mawola atatu kapena anayi napukuta kuchokera maelekitirodi panopa. Patapita maola 24 electrolysis Chinawonjezeka 90 ga sulphate wosweka ammonium ndi electrolysis anapitiriza maola wina 70. Pa njira electrolysis akawinduka nthawi zonse. The makhiristo chifukwa cha persulfate ammonium anapatulidwa ndi njira akufunanso ladzala ndi sulphate ammonium acid sulphate acidified. The precipitate chifukwa nafota pa kutentha osati kuposa madigiri 40.

Monga ulamuliro, analandira malinga anati njira kukonzekera lili osati oposa 90% ammonium nadsernistogo, amagwiritsidwa ntchito kawirikawiri pamene oxidant ndi. A reagent ndi ndende apansi yogwira amenable kuti recrystallization. Kuti izo 700 ga mchere kusungunuka mu buku zofanana madzi ofunda (40 ° C). Komanso, ntchito yosema fyuluta pepala, mayeso njira ndi osasankhidwa, inatuluka ndi filtrate ndi utakhazikika. The makhiristo chifukwa anali mwayeretsa persulfate ammonium osasankhidwa pa Buchner nyuzi ndi osambitsidwa ndi madzi. Kukonza analandira zambiri akukwaniritsa ziyeneretso reagents q.s.p.

Ammonium persulfate - Zipangizo ndi moto umboni, koma kumathandiza kuti kuyaka zinthu zina. Mu ndondomeko ya moto kuchokera zinthu akutivutitsa ndi poizoni. Polumikizana anati reagent ndi zinthu kuyaka sikuloledwa, monga ukukamba oxidant amphamvu ndi amachitira ndi zinthu kuyaka, komanso kuchepetsa wothandizira. Pa Kutentha persulphate ammonium linawola mofulumira, ichi amapanga ambiri mpweya woipa komanso zikuwononga (oxides asafe, amoniya nthunzi, oxides sulfure). Mlingo wa chikoka pa thupi la munthu ndi m'modzi za zinthu za m'kalasi yachitatu ya ngozi. Zolemba malire analekerera mlingo m'dera ntchito kwa persulfate wa ammonium ndi 0,1 mg wa pa mita kiyubiki.

ammonium persulfate kuonetsa zimakhudzanso akutivutitsa pa khungu ndipo zimagwira ntchito zosiyanasiyana mucous wa m'mphuno ndi m'kamwa M'mimbamo thirakiti kupuma, conjunctiva. Inhalation wa thunthu amakwiya chitukuko cha matenda mphumu. Pamene yaitali kapena mobwerezabwereza kukhudzana zimachitika dermatitis, chikanga, nthawi zambiri limodzi ndi thupi lawo siligwirizana, chidawoneka urticaria ndi mantha.

Pamene tikugwira ntchito ndi reagent zofunika ntchito zosiyanasiyana zida munthu woteteza (makina, Goggles labala, ovololo).
