I-Benzoic acid CAS: 65-85-0

incazelo emfushane:

I-Benzoic acid, eyaziwa nangokuthi i-benzoic acid, inefomula yamangqamuzana engu-C6H5COOH. I-asidi enamakha elula kakhulu lapho iqembu le-carboxyl lixhunywe khona ngokuqondile ne-carbon athomu yeringi ye-benzene. Kuyinhlanganisela eyakhiwe ngokufaka i-hydrogen eringini ye-benzene neqembu le-carboxyl (-COOH). Ayinambala, amakristalu acwebile angenaphunga. Iphuzu elincibilikayo lingu-122.13℃, indawo yokubilisa ngu-249℃, kanti ukuminyana okuhlobene ngu-1.2659 (15/4℃). Yehlisa ngokushesha ku-100°C, futhi umhwamuko wayo uyacasula kakhulu futhi ungabangela ukukhwehlela kalula ngemva kokuhogela. Incibilika kancane emanzini, incibilika kalula kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-chloroform, i-benzene, i-toluene, i-carbon disulfide, i-carbon tetrachloride ne-pine Chemicalbook ukonga uphethiloli. Itholakala kabanzi ngokwemvelo ngesimo se-asidi yamahhala, i-ester noma okuphuma kuyo. Isibonelo, ikhona ngesimo se-asidi yamahhala ne-benzyl ester ku-benzoin gum; ikhona efomini yamahhala emaqabunga nesiqu segxolo lezinye izitshalo; ikhona kuphunga Ikhona ngesimo se-methyl ester noma i-benzyl ester emafutheni abalulekile; ikhona ngesimo se-hippuric acid ephuma kumchamo wehhashi. I-Benzoic acid iyi-asidi ebuthakathaka, enamandla kunama-fatty acids. Zinezici ezifanayo zamakhemikhali futhi zingakha usawoti, ama-esters, ama-asidi halides, ama-amide, ama-anhydride ane-asidi, njll., futhi awafakwa kalula i-oxidized. Ukusabela kwe-electrophilic substitution kungenzeka eringini ye-benzene ye-benzoic acid, ikakhulukazi ukukhiqiza imikhiqizo eshintshwayo ye-meta.
I-Benzoic acid ivame ukusetshenziswa njengesidakamizwa noma isilondolozi. Inomphumela wokuvimbela ukukhula kwesikhunta, amagciwane kanye nesikhunta. Uma isetshenziselwa ukwelapha, ngokuvamile isetshenziswa esikhumbeni ukwelapha izifo zesikhumba ezifana nezikelemu. Isetshenziswa kuma-synthetic fibers, ama-resin, ama-coatings, irabha nezimboni zikagwayi. Ekuqaleni, i-benzoic acid yakhiqizwa yi-carbonization ye-benzoin gum noma i-hydrolysis yencwadi yamakhemikhali ngamanzi ane-alkali. Ingabuye ikhiqizwe yi-hydrolysis ye-hippuric acid. Ngokwezimboni, i-benzoic acid ikhiqizwa i-air oxidation ye-toluene phambi kwama-catalysts afana ne-cobalt ne-manganese; noma ikhiqizwa i-hydrolysis kanye ne-decarboxylation ye-phthalic anhydride. I-Benzoic acid kanye nosawoti wayo we-sodium ingasetshenziswa njengama-antibacterial e-latex, umuthi wokuxubha amazinyo, ujamu noma okunye ukudla, futhi ingasetshenziswa njengama-mordants ukudaya nokuphrinta.

Omaka bomkhiqizo

Isingeniso somkhiqizo

I-Benzoic acid, eyaziwa nangokuthi i-benzoic acid, iyancibilika kancane emanzini futhi incibilika kalula kuzincibilikisi eziphilayo njenge-ethanol, i-ether, i-chloroform, i-benzene, i-toluene, i-carbon disulfide, i-carbon tetrachloride ne-turpentine. Itholakala kakhulu emvelweni ngesimo se-asidi yamahhala, i-ester noma okuphuma kuyo. I-Benzoic acid iyi-asidi ebuthakathaka futhi inamandla kune-fatty acids. Zinezici ezifanayo zamakhemikhali futhi zingakha usawoti, ama-esters, ama-asidi halides, ama-amide, ama-anhydride ane-asidi, njll., futhi awafakwa kalula i-oxidized. Ukusabela kwe-electrophilic substitution kungenzeka eringini ye-benzene ye-benzoic acid, ikakhulukazi ukukhiqiza imikhiqizo eshintshwayo ye-meta.

Inkambu yohlelo lokusebenza

I-Benzoic acid ivame ukusetshenziswa njengesidakamizwa noma isilondolozi. Inomphumela wokuvimbela ukukhula kwesikhunta, amagciwane kanye nesikhunta. Uma isetshenziselwa ukwelapha, ngokuvamile isetshenziswa esikhumbeni ukwelapha izifo zesikhumba ezifana nezikelemu. Isetshenziswa kuma-synthetic fibers, ama-resin, ama-coatings, irabha nezimboni zikagwayi. Ekuqaleni, i-benzoic acid yakhiqizwa yi-carbonization ye-benzoin gum noma i-hydrolysis yamanzi ane-alkali. Ingabuye ikhiqizwe yi-hydrolysis ye-hippuric acid. Ngokwezimboni, i-benzoic acid ikhiqizwa i-air oxidation ye-toluene phambi kwama-catalysts afana ne-cobalt ne-manganese; noma ikhiqizwa i-hydrolysis kanye ne-decarboxylation ye-phthalic anhydride. I-Benzoic acid kanye nosawoti wayo we-sodium ingasetshenziswa njengama-bacteriostatic agents ku-latex, umuthi wokuxubha amazinyo, ujamu noma okunye ukudla, futhi ingasetshenziswa njengama-mordants ukudaya nokuphrinta.
