Anisole reacts huvnrog cov nyiaj sib npaug ntawm sulfuric lossis fluorosulphuric acid hauv trifluoroacetic acid los ua 4-methoxy-benzenesulphonic acid.
Sulfuric acid ua li cas nrog?
Sulfuric acid reacts hnyav nrog cawv thiab dej tso cua sov. Nws reacts nrog cov hlau feem ntau, tshwj xeeb tshaj yog thaum diluted nrog dej, tsim cov roj hydrogen flammable, uas yuav ua rau muaj kev phom sij tawg.
Dab tsi yog sulfuric acid tsis hnov mob nrog?
Concentrated sulfuric acid yog cov kua qaub uas tsis muaj zog (saib cov kua qaub thiab cov hauv paus) thiab cov electrolyte tsis zoo vim tias nws me ntsis yog dissociated rau ions ntawm chav tsev kub. Thaum txias nws tsis hnov mob nrog xws li cov hlau xws li hlau lossis tooj liab.
Cov tshuaj tiv thaiv ntawm dilute sulfuric acid ntawm anisol yog dab tsi?
H2SO4 (nitrating sib tov), anisole muab ortho thiab para nitro anisol. Methoxy pab pawg (−OCH3 pab pawg) yog qhib thiab ortho para directing pawg.
Cov tshuaj tiv thaiv ntawm anisol yog dab tsi?
Cov phenol reacts nrog sodium hydroxide thiab muab phenoxide ion uas reacts nrog methyl muab anisol. Nov yog cov lus teb yog lawm.

Leej twg nrhiav tau sulfuric acid?
Qhov kev tshawb pom ntawm sulfuric acid tau lees paub rau 8th caug xyoo alchemist Jabir ibn Hayyan. Sulfuric acid ua ntej li cas? Nyob rau xyoo pua 17th, German-Dutch chemist Johann Glauber tau npaj sulfuric acid los ntawm kev hlawv sulfur ua ke nrog ntsev (potassium nitrate, KNO 3 ), nyob rau hauv lub xub ntiag ntawm chav.
Puas yog magnesium hnov mob nrog dilute sulfuric acid?
Magnesium reacts nrog dilute sulfuric acid los ua magnesium sulphate thiab hydrogen gas. Qhov no yog ib qho kev hloov pauv ib zaug thiab kuj exothermic. Yuav ua li cas thaum magnesium reacts nrog dilute sulfuric acid? Cov tshuaj tiv thaiv magnesium ribbon nrog dilute sulfuric acid rau form magnesium sulphate thiab hydrogen yog kev sib xyaw ua ke.

Thaum txias nws tsis hnov mob nrog cov hlau xws li hlau lossis tooj liab.
Thaum twg ntxiv sulfuric acid rau roj teeb?
Thaum koj pom koj roj teeb acid theem pib poob, koj yuav xav tias thaum twg thiab yog tias tsim nyog ntxiv kua qaub, lossis tsuas yog dej xwb. Peb pom zoo tias tshwj tsis yog lub roj teeb tau ntsoog thiab tag nrho cov kua qaub ntws tawm, uas koj ntxiv cov dej distilled nkaus xwb.
