Ammonium persulfate: kwetunhu uye anoshanda. kukosha

Ammonium persulfate inoshandiswa kuwedzera zviri polymerization muitiro, uyewo dzora panguva kwegadziriro rubbers, mapurasitiki uye latex, mune mapikicha, ari etching ose akadhindwa redunhu mapuranga. Izvi zvinhu dzimwe nguva inoshandiswa disinfection uye bleaching.

Ammonium persulfate: Physico-mushonga ehupfumi

Himreaktiv anomiririra Hauoneki ndiro, dzimwe nguva ane greenish Hue. Zvishoma soluble mu H 2 O (42.7%) pane imwe tembiricha kuti 15,5 ° C. Panguva muchidziisa pamusoro madhigirii 120 pirosernisty Ammonium siyana, apo okisijeni asunungurwa. Zvinofanira kucherechedzwa kuti yakaoma munyu inogona kuchengetwa zvachose nokusingaperi, apo nemadhaka munyu yava hydrolyzed pamwe kusunungurwa okisijeni uye senitrogen. Aqueous zvingaitwa of mukomboni vanotanga hydrolyze, kunyange nzvimbo tembiricha, apo tembiricha inokwira ari disintegration kwacho kunosimudzirwa. Kuti kuderedza manyowa, kuti aqueous rokugadzirisa pamusoro Ammonium persulfate Wakawedzerwa potassium alum kana sulfates kuti alkali simbi.

Ammonium persulfate: reongororo pamusoro

A reagent inotoda vakazvigadzirirwa electrolysis kuti Ammonium sulphate ari sulphate acid. Kuti aite izvi, tora nechirongo 20 cm dhayamita uye bhuku marita maviri uchidururwa imomo 1,7 fő kuti zvine Ammonium sulfate mhinduro uye milliliters mashanu ane sulphate acid. Next, kunoguma musanganiswa zvakaiswa pasi electrolysis kushandisa electrodes dzakagadzirwa Platinum waya. Kana nedanho electrolysis anotanga dzakafafadzwa Ammonium hydroxide, ipapo wedzera matatu shanu ml munhu zvine mhinduro ine Ammonium sulphate mune asidhi sulfate. Mushure ose maawa matatu kusvika mana uye akapukuta kubvisa iyezvino electrodes. Mushure maawa 24 electrolysis Wakawedzerwa 90 g yakapwanyika Ammonium sulfate uye electrolysis mberi kwemamwe maawa 70. Panguva electrolysis mhinduro ichibvongodzwa nguva dzose. The zvichiguma crystals pamusoro Ammonium persulfate chakaparadzaniswa uye inotoda zvakare zvakazara Ammonium sulphate uye iine acid sulphate acidified. The zvichiguma precipitate wasvava panguva tembiricha kwete kupfuura 40 inegumi.

Kazhinji, vakawana maererano akati nzira rokugadzirira rine asingapfuuri 90% Ammonium nadsernistogo, izvozvo rinowanzoshandiswa sechinhu oxidant. A reagent ane yakaderera Kuwanda vanoshingaira zvinhu amenable kuti recrystallization. Pariri 700 g munyu zvazvichanyungudutswa ane fanana Vhoriyamu mvura inodziya (anenge 40 ° C). Uyezve, kushandisa fluted Sefa bepa, muedzo inotoda yakasvinwa, dzakatsigira filtrate iri haachandidi. The zvichiguma crystals vakanga vazvinatsa Ammonium persulfate yakasvinwa pamusoro Buchner fanera uye nemvura. The gadziriro vakawana Kazhinji asangana zvinodiwa reagents q.s.p.

Ammonium persulfate - kuputika uye moto kuidzwa, asi zvinoita kuti combustion vamwe zvinhu. Mukuita yokupisa kubvisa kunovhiringidza uye zvine chepfu. Kubata akati reagent pamwe combustible zvinhu haabvumirwi, sezvo kwazvinoita yakasimba oxidant uye zvaanoita pamwe combustible zvinhu, uyewo yokuderedza nevamiririri. Panguva muchidziisa Ammonium persulphate uchiora nokukurumidza, ichi zvinowanisa yakawanda chepfu uye kungatikanganisa magasi (senitrogen oxides, amoniya nemhute, sarufa oxides). The mwero simba pamusoro mumuviri womunhu mumwe zvinhu mukirasi yechitatu ngozi. Maximum akashivirira dose rwekuita nzvimbo nokuda Ammonium persulfate iri 0.1 MG paavhareji cubic mita.

Ammonium persulfate kuratidza chinhu kunovhiringidza nomugumisiro ganda uye mucous membranes ari nasal, nemumuromo mhango, kufema turakiti, conjunctiva. Inhalation of fuma chinokurwadzai kukura asthmatic chirwere. Kana mazhinji kana akadzokorora kuonana kuitika dermatitis, eczema, kazhinji achiperekedzwa neutachiona, richiratidzwa sezvo urticaria uye kuvhunduka.

Kana uchishanda reagent zvakakodzera kushandisa dzakasiyana-siyana pachake unodzivirira midziyo (unomubatsira kufema, rabha magogorosi, overalls).
