Sulfuric acidKev siv
Sulfuric acid (hatso₄) yog ib qho ntawm feem ntau dav siv tshuaj lom vim nws versatility thiab reactivity. Nov yog qee qhov ntawm nws qhov tseem ceeb siv:
1. Siv thiab ua cov chiv tshawb phospholde chiv:Sulfuric acid CAS 7664-93-9 yog qhov tseem ceeb nyob rau hauv kev tsim cov tshuaj phospephe chiv. Nws nthuav tawm nrog phosphate pob zeb los tsim cov kua qaub phosphoric acid, uas yog siv los tsim chiv zoo li superphosphate.
2. Petroleum Refining Petroleum Cracking:Sulfuric acid CAS 7664-93-9 yog siv nyob rau hauv cov txheej txheem ua kom zoo ntawm roj av. Nws pab txhawm rau ua kom cov txheej txheem alkylation, qhov twg me me hydrocarbons tau sib xyaw ua ke los ua cov roj av loj dua, tsim cov roj ntiav siab-octural. Kev ntxuav tu: nws tseem siv los tshem tawm cov impurities los ntawm cov khoom siv roj av.
3. Tshuaj Raug Ntau Lawm Cov Tshuaj:Sulfuric acid cas 7664-93-9 yog cov khoom siv tseem ceeb hauv kev tsim ntau yam tshuaj lom neeg, suav nrog cov tshuaj acid (hco₃), thiab hluavtaws hluav taws xob. Catalyst: nws pabcuam ua cov tshuaj tua hluav taws xob, xws li kev tsim cov tshuaj txhuam alkylated (piv txwv li cov xab taws, dyes, thiab tshuaj).
4. Hlau ua pickling ntawm hlau:Sulfuric acid cas 7664-93-9}}}} Siv hauv cov hlau thiab lwm yam hlau los ntawm kev tshem cov xeb, nplai, thiab lwm yam tsis txaus ntseeg. Electroplating: Nws yog siv hauv qee cov txheej txheem electroplating los ntxuav cov hlau ua ntej plating.
5. Roj teeb raug ua cov-kua roj teeb:Sulfuric acid cas 7664-93-9 yog siv los ua cov roj teeb ua, uas feem ntau pom muaj cov roj teeb thiab tsis sib xws (UPS).
6Sulfuric acid CAS 7664-93-9 yog siv los kho cov pH hauv cov dej kho dej rau neutralize. Wastewater kev kho mob: nws tau siv rau neutralize cov khib nyiab alkaline thiab kho cov lag luam muaj effluents.
