Daim ntawv thov
DMAP yog ib qho zoo acylation catalyst nrog dav siv nyob rau hauv cov organic synthesis, tshuaj synthesis, tshuaj tua kab, tshuaj, dyes, fragrances, thiab lwm yam teb.
QA & QC
Lub tuam txhab muaj lub chaw ntsuas kev ntsuas, cov khoom siv HPLC thiab GC.
Yam ntim
Cov khoom yog ntim rau hauv cov duab los qhia nruas, hauv ob txheej txheej polyethylene hnab, 25kg / Nruas.
Cia
Cov khoom no yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, thiab qhov cua zoo, kaw. Cia. Cia tej yam kev mob yuav tsum zoo dua yog ib qho chaw tiv thaiv uas tsis tshua muaj kub variations thiab tsis tsawg humidity theem.Kov lub pob nrog dej los yog lwm yam kua ncaj qha yuav ua rau cov khoom rau ncuav mog qab zib, yuav tsum stacked nyob rau hauv pallets. Raws li ib txwm muaj, kev siv cov khoom no tsis ua rau muaj kev phom sij rau kev noj qab haus huv. Kev ceev faj yuav tsum tau ua kom tsis txhob muaj cov khoom ua kua los yog cov khoom ua kua rau kev sib cuag ntawm daim tawv nqaij lossis qhov muag.
Kev tuav thiab kev thauj mus los
{{0 {0}} dimethylaminopyridine (DMAP) ntim yog qhov haum rau txhua hom kev thauj mus los xws li nthuav tawm tus me nyuam, dav hlau, hiav txwv.
