N-Bromosuccinimide/NBS/CAS: 128-08-5

Kushandiswa

N-Bromosuccinimide, inowanzo pfupikiswa seNBS, chinhu chakanaka chekristaro chine ruvara ruchena kusvika ruchena. Inonyungudika muacetone, tetrahydrofuran, N,N-dimethylformamide, dimethyl sulfoxide, uye acetonitrile, inonyungudika zvishoma mumvura uye acetic acid, uye hainyungudike mu ether, hexane, uye carbon tetrachloride. NBS inowanzoshandiswa mu free radical bromination reactions ye allyl ne benzyl groups; electrophilic bromination reactions ye ketones, aromatic compounds, kana heterocyclic compounds; hydroxylation, etherification, uye lactonization reactions ye olefins. NBS inonzwa hunyoro uye inofanira kuchengetwa mufiriji. Munguva yekushandisa, kufema kana kubata ganda kunofanirwa kudzivirirwa, uye inowanzo shandiswa mu fume hood ine mhepo yakanaka.

Inoshandiswa semushonga wekuona doro rekutanga, rechipiri, uye rechitatu. Inogona kushandiswa kugadzira mishonga yebromoacetonitrile. Muindasitiri yemishonga yezvipembenene, inoshandiswa kugadzira thiabendazole uye inogona zvakare kushandiswa semushonga wekuchengetedza michero, mushonga wekuuraya utachiona, uye mushonga wekudzivirira mildew, nezvimwewo. Ichinhu chisina kugadzirwa cheorganic synthesis, chinoshandiswa kudzora maitiro ebromination ane simba shoma, uye chinoshandiswawo mukugadzira zvinowedzerwa zverabha nemishonga. Inogona kushandiswa kugadzira bromoacetonitrile yemishonga. Muindasitiri yemishonga yezvipembenene, inoshandiswa kugadzira thiabendazole uye inogonawo kushandiswa semushonga wekuchengetedza michero, mushonga wekuuraya utachiona, uye mushonga wekudzivirira mildew. Inoshandiswa semushonga wekuona doro rekutanga, rechipiri, uye rechitatu uye muwedzero yezvigadzirwa zverabha, uye inoshandiswawo mukugadzirwa kweorganic. Imushonga unokosha webrominating mukugadzirwa kweorganic. Muindasitiri yemishonga, inowanzo shandiswa semushonga webrominating mukugadzirwa kwemishonga inorwisa mabhakitiriya, senge kugadzira cefaloram. Organic synthesis. Bromination yeolefins. Oxidation yeethanol kualdehydes nemaketones. Kuoxidation yealdehydes kuita bromo - acids. Mushonga webrominating unoshanda zvakawanda. Unoshandiswa mukuita oxidation yetryptophan, asi mwero weoxidation wetyrosine, histidine, uye methionine residues unogona kunge wakaderera. Unogona zvakare kushandiswa mukushandura mapoka e ribosomal thiol. Imushonga webrominating universal. Kana paine AIBN, silyl ethers inogona oxidized kuita aldehydes. Imushonga webrominating universal; unoshandiswa muoxidation yetryptophan, kunyangwe paine tyrosine, histidine, uye methionine oxidation residues zvishoma; unoshandiswa mukushandura mapoka e ribosomal thiol; kana paine AIBN, silyl ethers dzinooxidized kuita aldehydes.

Nguva yesherufu: Mwedzi makumi maviri nemana kubva pazuva rekugadzirwa kwayo, yakachengetwa munzvimbo inotonhorera yakaoma isina chiedza chezuva, mvura.
Imba yekuchengetera zvinhu ine mhepo, Inoomesa zvinhu zvishoma, Yakaparadzaniswa nezvinokonzera makemikari, maasidhi.

Imba yekuchengetera zvinhu inofanira kunge ine mhepo inofefetera, ichichengetwa patembiricha yakaderera uye yakaoma. Chengeta zvakasiyana neaniline, dialkyl sulfide, hydrazine hydrate, peroxides uye propionitrile.
