Pyridinium chlorochromate CAS 26299-14-9 yog piv nrog rau lwm cov khoom siv chromium-muaj oxidants xws li jons reagent, Colljn reagent, thiab lwm yam. Nws muaj zog oxidizing muaj peev xwm, zoo xaiv, thiab olefinic daim ntawv cog lus ntawm lub substrate molecule Chemicalbook tsis cuam tshuam lub sij hawm. txheej txheem oxidation. , thiab yooj yim rau kev khiav lag luam. Tsis tas li ntawd, acidity ntawm PCC tsis muaj zog, yog li cov pab pawg uas tsis ruaj khov rau cov kua qaub tseem tuaj yeem khaws cia thaum oxidation.
Ntseeg tshuaj yog ib tug ua Tuam Tshoj Pyridinium chlorochromate CAS26299-14-9manufacturers, tsum thiab exporter. Ua raws li kev ua raws li cov khoom zoo tshaj plaws, kom peb cov Pyridinium chlorochromate CAS 26299-14-9 tau txaus siab los ntawm ntau tus neeg siv khoom. Shandong Ntseeg
Peb cov khoom raug xa tawm mus rau Tebchaws Europe, Tebchaws Meskas, Nyiv, Kaus Lim Qab Teb, Sab Hnub Tuaj Asia thiab lwm lub tebchaws thiab cheeb tsam. Nrog rau kev tshawb fawb thiab thev naus laus zis raws li kev qhia, kev ncaj ncees raws li lub hauv paus, zoo li lub neej, thiab tso siab rau lub tswv yim kev lag luam ntawm kev tsim kho tshiab thiab kev loj hlob, peb cia siab tias yuav tsim kev sib pauv thiab kev koom tes nrog cov neeg siv khoom hauv tsev thiab txawv teb chaws los tsim kev vam meej!

Pyridine chlorochromate, feem ntau abbreviated NBS, yog ib tug me me oxidizing tus neeg saib xyuas nrog txiv kab ntxwv-daj crystals. Rau qhov txwv oxidation ntawm cawv rau aldehydes, qhov tsis zoo ntawm kev siv PCC yog lub sij hawm ntev cov tshuaj tiv thaiv thiab cov tshuaj toxicity ntawm PCC. Cov reagent nws tus kheej tsis muaj zog acidic, yog li nws feem ntau siv nrog rau qhov tsis xws li sodium acetate.
Oxidizer, xaiv oxidizes cawv. Nyob rau hauv Grubbs-catalyzed nplhaib-kaw decomposition ntawm D-glucose los ua ke unsaturated lactones rau oxidation ntawm allylmethylene pawg.
