Ammonium persulfate: kira da m muhimmancin

ammonium persulfate ake amfani da su ƙara da Polymerization tsari, kazalika da cunkoso a lokacin shiri na rubbers, robobi da kuma latex, a cikin daukar hoto, a cikin etching na buga kewaye allon. Wannan abu ne wani lokacin amfani ga disinfection da bleaching.

Ammonium persulfate: Physico-sinadaran Properties

Himreaktiv wakiltar colorless faranti, wani lokaci tare da wani greenish ya dafa. Dan kadan mai narkewa a cikin H 2 Ya (42.7%) a zazzabi na 15,5 ° C. A lokacin dumama sama 120 digiri pirosernisty ammonium siffofin, yayin da oxygen da aka saki. Ya kamata a lura cewa bushe gishiri za a iya adana kusan illa ma sha Allahu, yayin da rigar gishiri ne hanzari hydrolyzed tare da saki na oxygen da kuma nitrogen. Mai ruwa-ruwa mafita na fili fara hydrolyze, ko da a dakin da zazzabi, idan zafin jiki yakan disintegration tsari ne inganta. Domin rage da bazuwar, to mai ruwa-ruwa mafita daga ammonium persulfate aka kara potassium alum ko sulfates Alkali karafa.

Ammonium persulfate: kira na

A reagent bayani ne ta shirya electrolysis na ammonium sulphate a sulphate acid. Don yin wannan, kai mai jar 20 cm diamita da kuma wani juz'i na biyu lita aka zuba a cikinta 1.7 lita na cikakken ammonium sulfate bayani da kuma biyar milliliters na wani sulphate acid. Next, sakamakon cakuda da aka hõre electrolysis yin amfani da wayoyin sanya na platinum waya. Idan a cikin aiwatar da electrolysis fara jin warin na ammonium hydroxide, sa'an nan ƙara uku zuwa biyar ml na wani cikakken bayani na ammonium sulphate a acid sulfate. Bayan kowane uku zuwa hudu hours kuma goge kashe halin yanzu wayoyin. Bayan 24 hours electrolysis aka kara 90 g na murƙushe ammonium sulfate da electrolysis ci gaba ga wata 70 hours. A lokacin electrolysis bayani ne zuga a kai a kai. A sakamakon lu'ulu'u na ammonium persulfate aka raba da bayani ne a sake tare da cikakken ammonium sulphate da kuma acid sulphate acidified. A sakamakon precipitate ya bushe a zazzabi ba fi 40 digiri.

Matsayin mai mulkin, ya samu bisa ga ce Hanyar shiri ƙunshi ba fiye da 90% ammonium nadsernistogo, shi ne sau da yawa amfani da matsayin oxidant. A reagent da ƙananan taro na aiki abubuwa amenable ga recrystallization. Don shi 700 g na gishiri narkar da a wani m girma na dumi ruwa (game da 40 ° C). Bugu da ari, ta amfani da fluted tace takarda, da gwajin bayani ne tace, sa'ilin da filtrate an sanyaya. A sakamakon lu'ulu'u ne da aka tsarkake ammonium persulfate tace a kan wani Buchner mazurari da kuma wanke da ruwa. A shirye-shiryen samu ne kullum ya gana da cancantar reagents q.s.p.

Ammonium persulfate - Fashewa da kuma wuta da hujja, amma na taimaka wa konewa na sauran abubuwa. A kan aiwatar da kona kashe irritating da guba abubuwa. Tuntužar ce reagent da combustible abubuwa ba a yarda, kamar yadda dangantaka da wani karfi oxidant da reacts tare da combustible abu, kazalika da rage jamiái. A lokacin dumama ammonium persulphate decomposes hanzari, wannan ya haifar da wani yawa na mai guba da kuma lalatattu gas (nitrogen oxides, ammonia tururi, sulfur oxides). A mataki na tasiri a jikin mutum shi ne daya daga cikin abubuwa na uku aji na hatsari. Matsakaicin jure kashi a cikin aiki yanki na ammonium persulfate ne 0.1 MG da cubic mita.

ammonium persulfate nuna wani irritating sakamako a kan fata da kuma mucous membranes na hanci, baka rami, numfashi fili, conjunctiva. Inhalation na abu tsokani ci gaban asthmatic cuta. Lokacin da tsawo ko maimaita lamba faruwa dermatitis, eczema, sau da yawa tare da rashin lafiyan halayen, bayyana a matsayin urticaria da kuma buga.

Lokacin aiki tare da wata reagent zama dole yin amfani da wani iri-iri na sirri m kayan aiki (respirator, roba fitattun idanu, overalls).
