Shiri na sulfuric acid da kuma ta fannin aikace-aikace.

Yau, da shiri na sulfuric acid da aka samar yafi biyu masana'antu tafiyar matakai: lamba kuma nitrogen. Contact Hanyar ne mafi m, kuma a Rasha da shi da ake amfani da mafi baje fiye da nitrous, watau hasumiya.

Shiri na sulfuric acid farawa tare da harbe-harben da sulphurous kayan, msl, da baƙin ƙarfe pyrites. A musamman Tanderu pyrite samu don haka ya kira kiln gas, wanda ya ƙunshi game 9% na sulfur dioxide. Wannan mataki ne guda ga lamba kuma ga nitrous Hanyar.

Next, sakamakon oxidized sulfur dioxide zuwa sulfur. Duk da haka, dole ne a pre-tsabtace daga wani adadin impurities wanda tsoma baki tare da kara tsari. A calcined gas tsarkake daga turɓãya a precipitators ko cyclone na'ura, sa'an nan kawota ga na'ura, hada da wani m lamba taro, inda sulfur dioxide SO ₂ da aka oxidized zuwa sulfur trioxide SO _3.

Wannan exothermic dauki reversible - karuwa a yawan zafin jiki take kaiwa zuwa bazuwar daga cikin kafa sulfur trioxide. A daya hannun, a lokacin da zafin jiki da aka saukar da gaba dauki kudi ne sosai m. Saboda haka, da yawan zafin jiki a cikin contactor ne kiyaye a cikin 480 ^{° C} da daidaitawa ta gudun nassi na gaseous cakuda.

Daga bisani kafa a lamba yanayin sulfuric acid tare da wani fili na sulfur trioxide da ruwa.

Nitrous Hanyar ne halin a cewa sulfur dioxide da aka oxidized nitrogen oxides. Shiri na sulfuric acid da wannan hanya da aka fara da samuwar sulfurous acid a cikin hulda da sinadarin sulfur dioxide daga ƙõnuwa gas da ruwa. Daga bisani sakamakon sulfurous acid da aka oxidized tare da nitric acid, sakamakon samuwar nitrogen monoxide da sulfuric acid.

Wannan dauki cakuda an ciyar a cikin wani musamman hasumiya. Saboda haka, ta hanyar daidaitawa da gas da kwarara don tabbatar da cewa gas cakuda fadowa cikin sha hasumiya dioxide da nitrogen monoxide kunshe ne a cikin wani rabo daga 1: 1 wajibi ne a samu da nitrogenous anhydride.

A karshe, ta maida martani sulfuric acid da nitrous anhydride kafa NOHSO ₄ - nitrosylsulfuric acid.

A sakamakon nitrosylsulfuric acid da aka ciyar da su da samar da hasumiya inda shi decompose ruwa, nitrous anhydride allocates:

2NOHSO ₄ + H ₂ Ya = N ₂ Ya ₃ + 2h ₂ SO _4,

wanda oxidizes da sulfurous acid kafa a cikin hasumiya.

Nitric oxide saki a cikin sakamakon dauki an sake mayar da su zuwa da hadawan abu da iskar shaka da kuma hasumiyar shiga wani sabon sake zagayowar.

A halin yanzu, da shiri na sulfuric acid Rasha samar da yafi by lamba. Nitrous Hanyar da aka yi amfani da wuya.

A amfani da sulfuric acid ne mai fadi da kuma bambance bambancen.

Mafi yawa daga shi ke samar da sinadaran zaruruwa da kuma ma'adinai da takin mai magani, shi wajibi ne a samar da magunguna da kuma dyes. Amfani da sulfuric acid ba ethyl da sauran alcohols, ƙuna kuma magungunan kashe qwari.

Its mafita aka yi amfani a cikin yadi, da abinci masana'antu, a matakai domin samar da nitration da kuma bama-bamai. Sulfuric acid hidima a matsayin baturi electrolyte cika a gubar-acid batura, wanda ake amfani da ko'ina a cikin kai.
