I-Benzoic acid CAS: 65-85-0

incazelo emfushane:

I-Benzoic acid, eyaziwa nangokuthi i-benzoic acid, inefomula yama-molecule ye-C6H5COOH. Iyi-aromatic acid elula kakhulu lapho iqembu le-carboxyl lixhunywe khona ngqo kwi-athomu yekhabhoni yendandatho ye-benzene. Iyinhlanganisela eyakhiwe ngokufaka i-hydrogen endandatho ye-benzene esikhundleni seqembu le-carboxyl (-COOH). Ayinambala, amakristalu aqhekekile. Indawo yokuncibilika ingu-122.13℃, indawo yokubila ingu-249℃, kanti ubuningi obuhlobene bungu-1.2659 (15/4℃). Incibilika ngokushesha ku-100°C, futhi umhwamuko wayo uyacasula kakhulu futhi ungabangela ukukhwehlela kalula ngemva kokuphefumula. Incibilika kancane emanzini, incibilika kalula ezinyibilikisweni eziphilayo ezifana ne-ethanol, i-ether, i-chloroform, i-benzene, i-toluene, i-carbon disulfide, i-carbon tetrachloride kanye ne-pine Chemicalbook fuel saving. Itholakala kabanzi ngokwemvelo ngesimo se-free acid, i-ester noma izinto zayo eziphuma kuyo. Isibonelo, ikhona ngesimo se-asidi yamahhala kanye ne-benzyl ester ku-benzoin gum; ikhona ngesimo samahhala emaqabunga kanye negxolo lesiqu sezitshalo ezithile; ikhona ephunga. Ikhona ngesimo se-methyl ester noma i-benzyl ester emafutheni abalulekile; ikhona ngesimo se-hippuric acid yayo evela kumchamo wehhashi. I-Benzoic acid iyi-asidi ebuthakathaka, enamandla kune-fatty acids. Inezakhiwo ezifanayo zamakhemikhali futhi ingakha usawoti, ama-ester, ama-acid halides, ama-amides, ama-acid anhydrides, njll., futhi ayikhiqizi kalula. Ukusabela kokushintshana kwe-electrophilic kungenzeka eringini ye-benzene ye-benzoic acid, ikakhulukazi ikhiqiza imikhiqizo ye-meta-substitution.
I-Benzoic acid ivame ukusetshenziswa njengesidakamizwa noma isilondolozi. Inomphumela wokuvimbela ukukhula kwesikhunta, amagciwane, kanye nesikhunta. Uma isetshenziswa kwezokwelapha, ivame ukusetshenziswa esikhumbeni ukwelapha izifo zesikhumba ezifana ne-ringworm. Isetshenziswa kumafayibha okwenziwa, ama-resin, ama-coating, irabha, kanye nezimboni zikagwayi. Ekuqaleni, i-benzoic acid yakhiqizwa ngokufakwa kwe-carbonization kwe-benzoin gum noma i-hydrolysis ye-chemical book ngamanzi ane-alkaline. Ingakhiqizwa futhi ngokufakwa kwe-hydrolysis ye-hippuric acid. Kwezimboni, i-benzoic acid ikhiqizwa ngokufakwa kwe-toluene emoyeni lapho kukhona izinto ezibangela ukuguga ezifana ne-cobalt ne-manganese; noma ikhiqizwa ngokufakwa kwe-hydrolysis kanye ne-decarboxylation ye-phthalic anhydride. I-Benzoic acid kanye nosawoti wayo we-sodium ingasetshenziswa njengezinto ezilwa namagciwane ku-latex, i-toothpaste, i-jam noma okunye ukudla, futhi ingasetshenziswa njengezinto zokufaka umbala nokuphrinta.

Isingeniso somkhiqizo

I-Benzoic acid, eyaziwa nangokuthi i-benzoic acid, incibilika kancane emanzini futhi incibilika kalula ezinyibilikisini eziphilayo ezifana ne-ethanol, i-ether, i-chloroform, i-benzene, i-toluene, i-carbon disulfide, i-carbon tetrachloride kanye ne-turpentine. Itholakala kabanzi emvelweni ngesimo se-free acid, i-ester noma izinto eziphuma kuyo. I-Benzoic acid iyi-acid ebuthakathaka futhi inamandla kune-fatty acids. Inezakhiwo ezifanayo zamakhemikhali futhi ingakha usawoti, ama-ester, ama-acid halides, ama-amides, ama-acid anhydride, njll., futhi ayincibiliki kalula. Ukusabela kokushintshana kwe-electrophilic kungenzeka eringini ye-benzene ye-benzoic acid, ikakhulukazi kukhiqize imikhiqizo ye-meta-substitution.

Inkambu yohlelo lokusebenza

I-Benzoic acid ivame ukusetshenziswa njengesidakamizwa noma isilondolozi. Inomphumela wokuvimbela ukukhula kwesikhunta, amagciwane, kanye nesikhunta. Uma isetshenziswa kwezokwelapha, ivame ukusetshenziswa esikhumbeni ukwelapha izifo zesikhumba ezifana ne-ringworm. Isetshenziswa kumafayibha okwenziwa, ama-resin, izinto zokumboza, irabha, kanye nezimboni zikagwayi. Ekuqaleni, i-benzoic acid yakhiqizwa ngokufakwa kwe-benzoin gum noma i-hydrolysis yamanzi e-alkaline. Ingakhiqizwa futhi ngokufakwa kwe-hydrolysis ye-hippuric acid. Kwezimboni, i-benzoic acid ikhiqizwa ngokufakwa kwe-toluene emoyeni lapho kukhona izinto ezibangela ukuguga ezifana ne-cobalt ne-manganese; noma ikhiqizwa ngokufakwa kwe-hydrolysis kanye ne-decarboxylation ye-phthalic anhydride. I-Benzoic acid kanye nosawoti wayo we-sodium ingasetshenziswa njengezinto ezibangela ukuguga ku-latex, e-toothpaste, e-jam noma okunye ukudla, futhi ingasetshenziswa njengezinto zokudaya nokunyathelisa.

Izimakethe zethu eziyinhloko zifaka phakathi iMelika, iNdiya, i-Afrika, i-Indonesia, iTurkey, iNingizimu-mpumalanga ye-Asia, iNtshonalanga ye-Asia njalonjalo. Imikhiqizo emikhulu ye-MIT-IVY Industry ihlanganyela u-97% wemakethe yasekhaya egxile ekukhiqizeni nasekuphatheni, Singahlinzeka ngemikhiqizo ngezindleko ezincintisanayo. ngekhwalithi ephezulu kanye nentengo futhi siyakwamukela ukubonisana. Inkampani yethu inabantu abangochwepheshe abagxile ku-R&D yamakhemikhali kanye nokuphathwa okuzinzile, bahlinzeka ngemikhiqizo emihle yamakhemikhali enekhwalithi ephezulu kanye nensizakalo eseduze, futhi bahlinzeka ngemikhiqizo eyenzelwe wena ngokwezidingo zamakhasimende ethu. Sineqembu elisebenzayo lokuphatha elihle nelizikhuthazayo elinefilosofi efanayo, ukunakekela kanye nokuzibophezela ngokusebenzisana, ithimba lethu lilwela ukufeza impumelelo ekujabuliseni amakhasimende ethu kanye nathi. Siqhubeka nokuthuthukisa imikhiqizo yethu futhi sithuthukisa inethiwekhi yethu yesevisi, yokuthengisa. Ngakho-ke, siqala imodi yokuqala yokuthengisa ku-inthanethi eShayina, okuwukuhweba ngokuthengisa kwamaphakheji amancane okuletha izindlela zokuphatha ezahlukahlukene ngobuningi. Imikhiqizo yethu ithunyelwa kabanzi eNingizimu Korea, eVietnam, e-Australia, eYurophu naseNingizimu Melika, enconywe kakhulu ngamakhasimende ethu. Sigcizelela inkolelo yokuphatha ethi "Imakethe iyikhampasi yethu, Ikhwalithi iyimpilo yethu, Isikweletu siyimphefumulo wethu". Ukwethembana kwamakhasimende kuyisipho sethu sokuqala, ukwaneliseka kwabo kuyinjongo yethu enzima.

Isevisi Yamakhasimende Yomkhiqizo:
Inethiwekhi yethu yethimba le-akhawunti yamakhasimende e-JIT eShayina ithuthukisa futhi isebenzise imiqondo eyenzelwe wena ukuze amakhasimende ethu athole amakhemikhali ezimboni nawochwepheshe.
Izinzuzo zakho:
● Isevisi yamakhasimende ehlanganisiwe isekela ukwenza lula izinqubo zokuphatha, okuholela ekongeni isikhathi kanye nezindleko.
● Inethiwekhi yethu yaseShayina kanye nezixazululo zezokuthutha eziyinkimbinkimbi ziqinisekisa ukuthi amakhemikhali asezingeni elifanayo anikezwa amakhasimende anezindawo eziningana zokukhiqiza futhi anegalelo ekuphepheni ekuhleleni nasekuthembekeni kwezinqubo.
● Izinqubo zethu zithuthukiswa njalo futhi zivumelaniswa nezakhiwo nezidingo zamakhasimende ethu ezishintshashintshayo.

Ukuphakama kwensizakalo ye-Chemistry Logistics:
Insizakalo yokuthutha amakhemikhali iwubungcweti kakhulu futhi kufanele ibe ngcono ngaphansi kohlelo lwe-UN, ikakhulukazi ochungechungeni lwe-DGR Class. Sinikeza ikhambi lenhloso ekhethekile yokuthuthukisa insizakalo yokuthutha amakhemikhali kanye neqembu lokupakisha elifanele kanye nelebula lezinkampani zethu eziyinhloko. Amachweba ethu amakhulu aseShayina anezindawo zokugcina amakhemikhali ze-DGR ukusebenzisa amakhemikhali akhethekile nokusebenzisa wonke amaphepha ahlobene nawo.

Amakhono ethu okusabalalisa afaka:
● Ukulethwa okuguquguqukayo, izixazululo ezihlakaniphile
● Noma yini kusukela ekuthunyelweni okukhulu kwezinkulungwane zamathani kuye ekuthunyelweni okuncane kakhulu kwezimpahla ezipakishiwe ngisho namasampula.
● Ukugcinwa nokuthuthwa kwenqwaba yezimpushana noketshezi – ukuhanjiswa kwezimpahla emikhunjini – izimpushana noketshezi olukhulu
● Imithi, ukudla kanye nendawo yokugcina ukudla ngokwezindinganiso ezigunyaziwe
● Izinto ezihlukaniswe ngokweyunithi yebhizinisi kanye nokuhlukaniswa kwezingozi
