Kev siv tshuaj DMAC
Pharmaceutical Intermediates
N,N-Dimethylacetamide yog cov khoom siv tshuaj tseem ceeb uas siv dav hauv kev tsim cov tshuaj xws li amoxicillin thiab cephalosporins.
Polymer Synthesis
DMAC Chemical pom zoo solubility rau ntau yam resins, tshwj xeeb tshaj yog polyurethane thiab polyimide resins. Nws feem ntau yog siv los ua cov kuab tshuaj hauv cov cua sov- cov hluavtaws hluavtaws, cov yeeb yaj kiab yas, txheej, tshuaj, thiab acrylonitrile spinning.
Organic Pigments
Hauv cov organic pigment ntau lawm, ntau lub chaw ntiav DMAC ua cov kuab tshuaj.
Kev lag luam Petrochemical
Hauv cov txheej txheem petrochemical, DMAC ua haujlwm zoo heev. Nws accelerates cov tshuaj tiv thaiv xws li cyclization, halogenation, cyanation, alkylation, thiab dehydrogenation thaum txhim kho cov txiaj ntsig ntawm cov khoom tseem ceeb.
Lwm Daim Ntawv Thov
DMAC feem ntau siv los ua cov kuab tshuaj rau kev sib cais cov ntshiab benzene, cyclohexane, thiab cyclohexene hauv nylon 66 ntsev cyclohexanol nroj tsuag.
Nws kuj tseem tuaj yeem ua cov kuab tshuaj lossis co-catalyst hauv kev tsim tshuaj tua kab.
DMAC Tshuaj Ntim & Cia
Pob: Galvanized hlau nruas pob, 190kg / chim . 1000kg / IBC tank Ib 20GP tuaj yeem thauj tau 80 chim lossis 20 IBC tso tsheb hlau luam.
Cia hauv qhov chaw huv thiab qhuav.
