Taw qhia

Etodolac acid, tseem hu ua nitromethane sulfonic acid los yog TSA, yog ib qho inorganic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm etodolac acid:

 

Zoo:

Etodolac yog cov kua qaub uas muaj zog heev uas ua rau khaus thiab corrosive. Nws muaj peev xwm yaj tag nrho hauv dej los tsim cov kua qaub acidic. Nws ruaj khov ntawm chav tsev kub, tab sis tuaj yeem decompose los yog tawg ntawm qhov kub thiab txias, thaum raug tshav kub, los yog sib cuag nrog lwm yam tshuaj.

 

Kev Siv: Nws kuj tuaj yeem siv rau hauv kev kho corrosion ntawm hlau nto, electroplating txheej txheem thiab lwm yam teb.

 

Txoj kev:

Etodolac feem ntau yog npaj los ntawm cov tshuaj tiv thaiv ntawm nitromethane thiab sulfuric acid. Ua ntej, nitromethane yog reacted nrog concentrated sulfuric acid los tsim etoyl chloride. Etoyl chloride yog ces reacted nrog dilute sulfuric acid los yog dej los tsim nitromethane sulfonic acid.

 

Cov ntaub ntawv kev nyab xeeb:

Etodolac yog khaus thiab corrosive, thiab muaj teeb meem rau lub qhov muag, ua pa, thiab tawv nqaij. Hnav cov iav tiv thaiv, hnab looj tes thiab cov cuab yeej ua pa kom tsis txhob sib cuag nrog cov tawv nqaij thiab nqus pa. Thaum lub sijhawm khaws cia thiab siv, kev sib cuag nrog cov nplaim taws, cov khoom siv organic, oxidants, thiab lwm yam yuav tsum tau zam kom tsis txhob muaj kev phom sij txaus ntshai. Thaum pov tseg cov khoom pov tseg, cov kev cai kho mob sib raug zoo yuav tsum tau ua kom tsis txhob muaj kuab paug ib puag ncig thiab raug mob ntawm tus kheej.
