Tetraphenylphosphonium bromide CAS 2751-90-8 yog ib theem hloov pauv catalyst (Phasetransfercatalyst) daim ntawv thov yog cov cuab yeej tshiab tsim nyob rau hauv ob lub xyoos dhau los, vim nws kov yeej qhov tsis txaus ntawm qhov xav tau rau Chemicalbook polar aprotic solvents hauv heterogeneous organic synthesis, thiab cov tshuaj tiv thaiv heterogeneous. tuaj yeem ua tau raws li qhov mob me me, ua kom cov tshuaj tiv thaiv sai thiab txhim kho cov txiaj ntsig, yog li txhawb kev loj hlob ntawm cov organic synthesis.
Ntseeg Tshuaj yog ib tug ua Tuam Tshoj Tetraphenylphosphonium bromide CAS 2751-90-8 chaw tsim tshuaj paus, tsum thiab exporter. Ua raws li kev ua raws li cov khoom zoo tshaj plaws, kom peb cov Tetraphenylphosphonium bromide CAS 2751-90-8 tau txaus siab los ntawm ntau tus neeg siv khoom. Shandong Ntseeg
Peb zoo ntawm qhov zoo ntawm cov khoom siv tshuaj lom neeg hauv thaj chaw. 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!
