Xwm
kua tsis muaj xim nrog tshwj xeeb pungent tsw. Tsis txhob yaj hauv dej, soluble hauv ethanol, ether thiab benzene, ntawm 15 deg C thiab dej los yog nrog lub luag hauj lwm ntawm alkali nyob rau hauv aqueous tov los tsim benzoic acid thiab hydrochloric acid. Nyob rau hauv cov ntaub ntawv ntawm cov nplaim taws, kub kub los yog kev sib cuag nrog oxidant, muaj kev pheej hmoo ntawm combustion tawg. Cov tshuaj tiv thaiv nrog dej ua rau kub hnyiab ntawm cov pa phem thiab corrosive gases. Corrosive.
| Taw qhia | benzoyl chloride (CAS98-88-4 ib) kuj hu ua benzoyl chloride, benzoyl chloride, belongs rau ib hom kua qaub chloride. Ntshiab xim tsis muaj pob tshab flammable kua, raug rau huab cua pa luam yeeb. Cov khoom lag luam nrog lub teeb daj, nrog cov ntxhiab tsw muaj zog. Vapor ntawm lub qhov muag mucosa, daim tawv nqaij thiab ua pa ib ntsuj av tau muaj zog stimulating nyhuv, los ntawm stimulating lub qhov muag mucosa thiab kua muag. Benzoyl chloride yog ib qho tseem ceeb nruab nrab rau kev npaj dyes, fragrances, organic peroxides, tshuaj thiab resins. Nws kuj tau siv rau hauv kev yees duab thiab kev tsim cov tannins, thiab tau siv los ua cov roj stimulant hauv tshuaj tua rog. Daim duab 1 yog cov qauv qauv ntawm benzoyl chloride |
| txoj kev npaj | Hauv chav kuaj, benzoyl chloride tuaj yeem tau txais los ntawm distilling benzoic acid thiab phosphorus pentachloride nyob rau hauv cov xwm txheej tsis muaj dej. Txoj kev npaj ua lag luam tuaj yeem tau txais los ntawm kev siv thionyl chloride thiab benzaldehyde chloride. |
| qeb phom sij | Cov phom sij rau benzoyl chloride: 8 |
| Siv | benzoyl chloride yog ib qho nruab nrab ntawm cov tshuaj tua kab mob oxazinone, thiab tseem yog ib qho nruab nrab ntawm cov tshuaj tua kab benzenecapid, hydrazine inhibitor. benzoyl chloride yog siv los ua raw khoom rau organic synthesis, dyes thiab tshuaj, thiab raws li ib tug pib, dibenzoyl peroxide, tert-butyl peroxide, tshuaj tua kab, thiab lwm yam. Nyob rau hauv cov nqe lus ntawm cov tshuaj tua kab, yog ib yam tshiab ntawm inducible insecticide isoxazole thiophos (isoxathon. , Karphos) intermediates. Nws tseem yog ib qho tseem ceeb benzoylation thiab benzylation reagent. Feem ntau ntawm benzoyl chloride yog siv los tsim benzoyl peroxide, ua raws li kev tsim cov benzophenone, benzyl benzoate, benzyl cellulose thiab benzamide thiab lwm yam tseem ceeb tshuaj raw khoom, benzoyl peroxide rau lub polymerization pib ntawm yas monomer, polyester, epoxy, catalyst rau acrylic resin. ntau lawm, tus kheej-coagulant rau iav fiber ntau cov khoom, crosslinking tus neeg saib xyuas rau silicone fluororubber, roj refining, hmoov bleaching, fiber ntau decolorization, thiab lwm yam. Tsis tas li ntawd, benzoic acid yuav reacted nrog benzoyl chloride los tsim benzoic anhydride. Kev siv lub ntsiab ntawm benzoic anhydride yog ua tus neeg sawv cev acylating, ua ib feem ntawm bleaching tus neeg sawv cev thiab flux, thiab tseem nyob rau hauv kev npaj ntawm benzoyl peroxide. siv los ua cov tshuaj analytical reagents, kuj siv rau hauv txuj lom, organic synthesis |
