I-Benzoic acid CAS: 65-85-0

inkcazo emfutshane:

I-Benzoic acid, ekwaziwa ngokuba yi-benzoic acid, inefomula yemolekyuli ye-C6H5COOH. Yeyona asidi ilula ye-aromatic apho iqela le-carboxyl liqhagamshelwe ngqo kwi-atom yekhabhoni yeringi ye-benzene. Yikhompawundi eyenziwe ngokutshintsha i-hydrogen kwiringi ye-benzene ngeqela le-carboxyl (-COOH). Ayinambala, iikristale eziqhekekileyo ezingenavumba. Indawo yokunyibilika yi-122.13℃, indawo yokubila yi-249℃, kwaye ubuninzi bayo yi-1.2659 (15/4℃). Inyibilika ngokukhawuleza kwi-100°C, kwaye umphunga wayo uyacaphukisa kakhulu kwaye unokubangela ukukhwehlela emva kokuphefumla. Inyibilika kancinci emanzini, inyibilika lula kwizinyibilikisi ze-organic ezifana ne-ethanol, i-ether, i-chloroform, i-benzene, i-toluene, i-carbon disulfide, i-carbon tetrachloride kunye ne-pine Chemicalbook fuel saving. Ifumaneka kakhulu kwindalo ngohlobo lwe-asidi ekhululekileyo, i-ester okanye izinto eziphuma kuyo. Umzekelo, ikhona ngohlobo lwe-asidi ekhululekileyo kunye ne-benzyl ester kwi-benzoin gum; ikhona ngohlobo olukhululekileyo kumagqabi nakwigxolo lesiqu sezityalo ezithile; ikhona kwivumba elimnandi. Ikhona ngohlobo lwe-methyl ester okanye i-benzyl ester kwiioyile ezibalulekileyo; ikhona ngohlobo lwe-hippuric acid yayo evela kumchamo wehashe. I-Benzoic acid yi-asidi ebuthathaka, enamandla kune-fatty acids. Zineempawu ezifanayo zeekhemikhali kwaye zinokwenza iityuwa, ii-esters, ii-acid halides, ii-amides, ii-acid anhydrides, njl.njl., kwaye azikwazi ukunyibilikiswa lula. Impendulo yokutshintshwa kwe-electrophilic inokwenzeka kwindandatho ye-benzene ye-benzoic acid, ikakhulu ivelisa iimveliso ze-meta-substitution.
I-Benzoic acid idla ngokusetyenziswa njengeyeza okanye isigcini. Inefuthe lokuthintela ukukhula kwefungi, iibhaktheriya, kunye nomngundo. Xa isetyenziswa njengeyeza, idla ngokusetyenziswa eluswini ukunyanga izifo zesikhumba ezifana ne-ringworm. Isetyenziswa kwiifayibha zokwenziwa, ii-resins, ii-coating, irabha, kunye nemizi-mveliso yecuba. Ekuqaleni, i-benzoic acid yaveliswa ngokufaka i-carbonization ye-benzoin gum okanye i-hydrolysis ye-chemical book ngamanzi e-alkaline. Ingaveliswa nangokufaka i-hydrolysis ye-hippuric acid. Kwimizi-mveliso, i-benzoic acid iveliswa ngokufaka i-toluene emoyeni xa kukho izinto ezibangela ukuguga ezifana ne-cobalt kunye ne-manganese; okanye iveliswa ngokufaka i-hydrolysis kunye ne-decarboxylation ye-phthalic anhydride. I-Benzoic acid kunye netyuwa yayo yesodium ingasetyenziswa njengee-antibacterial agents kwi-latex, i-toothpaste, i-jam okanye ezinye izinto zokutya, kwaye ingasetyenziswa njengezinto zokudaya nokuprinta.
