Ibyerekeranye na Sufuru Ubururu 7

Numero ya CAS:1327-57-7

Ibyiza: ifu yubururu-bwijimye. Kudashonga mumazi, gushonga muri sodium sulfide yumuti nicyatsi kibisi. Ni ubururu-ibara ry'umuyugubwe muri acide sulfurike yibanze kandi ikavangwa nubururu bwijimye. Irangi rihinduka ibara ry'umuhondo ryoroshye ry'umuhondo mu gisubizo cy'ifu ya alkaline, kandi ibara ry'umwimerere rishobora kugarurwa nyuma ya okiside; Byashize burundu muri sodium hypochlorite igisubizo; Ihindura ibara ry'umuyugubwe wijimye kuri acide sulfurike

Uburyo bwo kubyaza umusaruro: nitrosation ya fenol sodium nitrite na acide sulfurike kugirango ikore p-nitrosyphenol, guhuza hamwe na o-toluidine yashonga muri acide sulfurike, kugabanya no guturika hamwe na sodium polysulfide hamwe numubare runaka wa sulferi, hanyuma binyuze muri okiside ya gaze, hanyuma ikanyura mu kuyungurura; , kumisha, kumenagura no kuvura bisanzwe kugirango bitange ibicuruzwa. Gukoresha ibikoresho bibisi (kg / t) O-toluidine (99%) 165-210 fenol (inganda) 185-220 sodium nitrite 195-230 soda ya caustic (100%) 1-20 soda ivu (inganda) 920-1120 aside sulfurike ( 100%) 900-1160 sulfure (99%) 430 sodium sulfide (63.5%) 480-620 Ifu ya Yuan 10

Imikoreshereze: Irakwiriye gusiga irangi ipamba, ikivuguto, viscose nigitambara cyayo, kandi irashobora no gukoreshwa mugusiga vinylon. Ibicuruzwa bisize irangi ryubururu nyamukuru ibara ryirangi, ibara rirasa. Irangi ryirangi rirakennye, biroroshye guhinduranya okiside ijana yumutuku, itambitse, ikibara gitukura nizindi nenge, cyane cyane ubururu bwa sulfuru yubururu BRN, Sulfuru yubururu 7 biroroshye kubyiga. Gukoresha irangi rya padi birashobora kugabanya impande zitukura, erythma nizindi nenge. Kuberako umubare wibyiciro bya sodium polysulfide ikoreshwa mugukora ibicuruzwa bitandukanye, amarangi yubucuruzi afite amabara atandukanye. Itara ry'ubururu ryitwa Sulfuru ubururu 7, itara ry'ubururu ritukura ryitwaAmazi yubururu 7, kandi itara ritukura ryitwa Sulfuru yubururu 7, rigomba kwitonderwa mugihe rishyizwe. Amazi yubururu 7 arashobora kubyazwa umusaruro ukoresheje o-nitroethylbenzene, ibicuruzwa biva mu musaruro wa chloramphenicol, aho kuba o-toluidine

Isosiyete yacu itanga umusaruroAmazi yumukara, Amazi Yumukara Amazi, Amazi yubururu 7.Ibicuruzwa byoherezwa muri Bangladesh. Ubuhinde. Pakisitani. Misiri, na Irani. Ibitangwa hamwe nubuziranenge byombi birahagaze neza. Icyingenzi ni inyungu yibiciro
