Niki Uzi Kubijyanye n'amabara ya sufuru (2)?

ubwoko

Ubwoko nyamukuru bwamabara ya sulfuru ni umukara wa sulfure (CI sulfure umukara 1). Itegurwa na hydrolyzing 2, 4-dinitrochlorobenzene hamwe na sodium hydroxide yumuti wa sodium dinitrophenol yumuti hafi yo gutekwa, hanyuma gushyushya no guteka hamwe na sodium polysulfide yumuti ku kigero runaka cya molekile, no kugabanya no gusohora sulfure mukibazo cyangwa nta gitutu. Nyuma ya sulfurizasiya irangiye, yumishwa neza na firime yumye kugirango ibone irangi ryumwimerere. Ihita ivangwa mu marangi yubucuruzi. Mugihe cya volcanisation, igipimo cya molekuline ya sodium phenol na sodium polysulfide, x (ni ukuvuga indangagaciro ya sulfure) muri sodium polysulfide Na2Sx hamwe nubushyuhe bwa reaction biratandukanye, kuburyo urumuri rwamabara yibicuruzwa byirabura bya sulferi bifite itandukaniro ryumucyo wicyatsi, icyatsi itara ritukura n'itara ritukura. Ikibi kinini cyamabara yumukara wa sulfure nikintu cyimyenda yoroheje. Ni ukubera ko molekile yumukara ya sulfide irimo sulfure ikora muburyo bwurunigi rwa polysulfide. Ibigize sulfuru ntibihinduka, kandi iyo irangi rishyushye cyangwa rigashyirwa mu kirere gishyushye kandi cyinshi, biroroshye okiside kuri acide sulfurike, bikavamo ubudodo bwimyenda y'ipamba. Mu myaka yashize, mugutezimbere umusaruro wumukara wa sulfure, umukara usanzwe wa sulfuru ukonjeshwa kugeza kuri 100 ℃ nyuma yo gukorwa, hanyuma aside ya fordehide na monochloroacetic yongerwamo imbaraga kugirango sulfure idahungabana mu irangi, hamwe n’umukara wa anti-sulfure wirabura. irangi ryakozwe.

Koresha

Irangi rya sufuru rikoreshwa kugirango rigabanuke kuri leucosome ikemurwa n'amazi hamwe na sodium sulfide cyangwa ifu yubwishingizi, hanyuma igahinduka igasubira mubintu byambere byamabara adashobora gushonga nyuma yo kwinjizwa n irangi binyuze muri okiside cyangwa izindi ngaruka, kugirango irangi rishyirwe kumarangi. .

Koresha

irangi rya sulfuru rikoreshwa cyane mugusiga fibre selile, ikoreshwa cyane mubudodo, imiterere nizindi myenda yinganda nigitambara kiremereye. Ubwoko bukoreshwa cyane ni sulfure Yuan, ubururu bwa sulfuru,

Igisubizo kigabanya

(1) Ibyiza byo kugabanya abakozi

1. Ibyiza bya Na2S

. Nibintu bigabanya, ariko kandi nimbaraga ikomeye ya alkali, ibintu bihamye. Kugabanya ubushobozi bwa sodium sulfide biri munsi yubwa fu yubwishingizi, alkaline iri munsi ya soda ya caustic kandi iruta ivu rya soda, kandi ifite ruswa ikomeye kuruhu.

(2) Sodium sulfide hydrolysis kuri NaHS, NaHS ku kugabanya irangi, birashobora kugaragara ko ubushobozi bwa sodium sulfide bugabanya isano na hydrolysis.

(3) Sodium sulfide itanga gaze ya H2S iyo ihuye na aside, bityo rero hagomba kwitonderwa kugirango idashyirwa hamwe na aside.

. Kubwibyo, igomba gufungwa iyo ibitswe, kandi ibiyigize bigomba gusesengurwa mugihe bidakoreshejwe igihe kirekire.
