Igama lekhemikhali: 2,5-Hexanedione

Amagama afanayo: Hexan-2,5-Dion; hexane-2,5-dione; acetonylacetone

Isisindo sama-molecule:C₆H₁₀I-THE₂

Ukubukeka: Uketshezi olukhanyayo onsundu

Ukuzinza: 1. Ungathintani nama-oxidants aqinile, ama-reducer anamandla, kanye ne-alkali enamandla. Indawo yokubilisa iphezulu, umusi uphansi, futhi ngokuvamile kuphephile ukuyisebenzisa ngaphansi kwezimo ezijwayelekile, kodwa kusadingeka ukunaka ukuvimbela umlilo. Ingaxutshwa namanzi, i-ethanol kanye ne-ether, kodwa hhayi nezinyibilikisi ze-hydrocarbon. Ayincibiliki futhi ezixazululweni ze-potassium hydroxide noma ze-potassium carbonate ezigxilile. Ingancibilikisa i-polymethyl methacrylate, i-polystyrene, i-polyvinyl acetate, i-vinyl chloride kanye ne-vinyl acetate copolymer, i-cellulose nitrate, i-phenolic resin kanye nezinye izinhlayiya zokwenziwa kanye ne-rosin, i-conch rosin, i-grease kanye nezinye izinhlayiya zemvelo. Ingancibilikisa ingxenye ye-shellac, i-dewaxed dama resin, i-glycerin trirosin ester, uwoyela we-cottonseed, njll.

2. Izakhiwo zamakhemikhali: Ukusabela okuvamile kwama-ketone. Isabela ne-diphosphorus pentasulfide ukuze yakhe i-2, 5-dimethylthiophene. I-2, 5-dimethylpyrrole yakheka uma isabela ngesisombululo se-alcohol-ammonia noma ishiswa nge-ammonium carbonate. Ukuphelelwa amanzi emzimbeni kukhiqiza i-2, 5-dimethylfuran. Isabela ne-2, 4-dinitrophenylhydrazine ukuze yakhe i-bis (2, 4-dinitrophenyl) hydrazone enephuzu lokuncibilika elingu-257 ° C.

3. Itholakala emaqabunga kagwayi ahlanziwe ngoketshezi kanye nasentuthwini.

4. Isikhuthazi sendawo esimaphakathi, ukugxilisa ingqondo okuphezulu kubangela ukubulala izinzwa.

I-2,5-Hexanedione isebenza njengesakhiwo esiwusizo esiguquguqukayo kanye nomlandeli oyinhloko ekuhlanganisweni kwemithi yesimanje. Isakhiwo sayo se-diketone esilinganayo, esinamaqembu amabili e-reactive carbonyl, siyenza ibe yindawo ebalulekile yokwakha amakhemikhali ayinkimbinkimbi e-heterocyclic kanye ne-cyclic aphakathi kwezithako eziningi zokwelapha ezisebenzayo (ama-API).

Izicelo zayo eziyinhloko zemithi zifaka:

Ukwenziwa Kwezicafu Ze-Heterocyclic: I-2,5-Hexanedione isetshenziswa ngokuyisisekelo ekwakhiweni kwe-Paal-Knorr ukukhiqiza ama-furan nama-pyrroles afakwe esikhundleni. Lawa masongo e-heterocyclic anamalungu amahlanu ayizakhiwo ezinelungelo kumakhemikhali ezokwelapha, akha umongo wemithi eminingi enemisebenzi eyahlukahlukene yezinto eziphilayo (isb., ama-antimicrobial, anti-inflammatory, kanye nama-kinase inhibitory).

Ukukhiqizwa Kwezinto Ezivela Ku-Pyrrole: Ngokuhlangana nama-amine ayinhloko, i-2,5-Hexanedione ikhiqiza ngempumelelo i-2,5-dimethylpyrrole kanye nezinto eziphuma kuyo. Lawa ma-pyrrole ngokwawo ayizinto ezibalulekile zokusebenza okwengeziwe kuma-molecule ayinkimbinkimbi asetshenziswa ocwaningweni nasekuthuthukisweni kwemithi.

I-Precursor to Cyclic Compounds: Le nhlanganisela ingabhekana nokusabela kwangaphakathi kwama-molecule ukuze yakhe ama-cyclohexenone derivatives, okuyizinto ezibalulekile zokuhlanganisa izinhlaka ze-steroidal kanye nezinye izinhlelo ze-cyclic ezihambisana nemithi.

I-Intermediate for Specialty Chemical: Isebenza njengento yokuqala ekuhlanganisweni kwe-intermediate yamakhemikhali athuthukile afakwa emithini yokugcina yemithi ehlose izindawo ezahlukene zokwelapha, okuhlanganisa izifo zesimiso sezinzwa esiyinhloko (CNS) kanye nezifo ezithathelwanayo.

Ngenxa yendima yayo kulezi zindlela ezibalulekile zokwenziwa, i-2,5-Hexanedione ichazwe ezinqubweni zokukhiqiza zama-API amaningana ajwayelekile kanye nemithi emisha yocwaningo. Izinga lethu lokuhlanzeka okuphezulu (>99%) liqinisekisa ukuhambisana, amaphrofayili okungcola okuphansi, kanye nokuhambisana nezindinganiso zekhwalithi eziqinile ezidingekayo ekukhiqizweni kwe-GMP yemithi, okusekela ukwanda okuthembekile kusukela ocwaningweni kuya ekukhiqizweni kwezentengiselwano.

1. Ubumsulwa obuphezulu 99.0% min

2.Sebenzisa ukunambitheka okuhlukahlukene.

3. Sinesitifiketi se-ISO 9001, ISO 14001 kanye ne-ISO22000, Sinesitifiketi se-HACCP, sinesitifiketi se-Halal kanye ne-kosher salo mkhiqizo.

5. Sinamandla amakhulu, ngakho-ke, sivame ukuba nesikhathi sokuhola esisheshayo.

6. Singakunikeza isampula yamahhala engu-10g-50g yokuhlolwa kwakho kwelebhu. Sivame ukuletha isampula ngeposi lamazwe ngamazwe njenge-DHL noma i-Fedex. Kuyashesha futhi kulula.

1. Ukupakisha isampula kungu-20g/30g/50g ngebhodlela ngalinye.

2. Ukupakisha okuncane kungu-1kg /5kg /10 kg ngebhodlela ngalinye.

3.25 kg ngedrama (idrama yepulasitiki yezinga lokudla, ayinapulasitiki, umbiko wesitifiketi somuntu wesithathu)

Ukupakisha nakho kungenziwa ngezifiso ngokwezidingo zamakhasimende
