Cov ntawv thov ntawm n-Heptane Solvent (CAS 142-82-5) yog dab tsi?

n{0}}Heptane Solvent yog dab tsi?

CAS 142-82-5 n-heptaneyog xim tsis muaj xim, tsis muaj zog alkane hydrocarbon thiab paub txog nws cov yam ntxwv, tsw qab me ntsis thiab feem ntau yog siv los ua cov kuab tshuaj hauv chav kuaj chemistry thiab hauv kev tsim cov nplaum, xim thiab tshuaj ntxuav.

n-heptane feem ntau yog tau los ntawm kev distillation ntawm cov roj crude hauv refineries. Nws yog siv nyob rau hauv kev lag luam tshuaj thiab nyob rau hauv lub chaw soj nstuam raws li ib tug txheej txheem tov thiab raws li ib tug hnyav nyob rau hauv lub tsim ntawm ntau yam tshuaj.

Dab tsi yog daim ntawv thov ntawm n-Heptane Solvent

n-heptane yog cov kuab tshuaj zoo heev rau cov uas tsis yog- cov khoom siv polar, rog thiab roj. Tshwj xeeb tshaj yog nyob rau hauv kev lag luam kws tshuaj, nws yog siv raws li ib tug inert hnyav, rau purification, recrystallization thiab ntxuav ntawm active tshuaj cov khoom xyaw (API). Qee cov roj hmab hluavtaws xws li polybutadiene yog tsim nyob rau hauv kev daws. Txij li thaum n-heptane yog tshuaj inert (nws tsis muaj li- hu ua functionality lossis functional group), nws yog ib qho hnyav zoo tagnrho rau cov tshuaj tiv thaiv no.

Cov roj hnyav lossis roj tuaj yeem diluted nrog parafins xws li n-heptane kom yooj yim rau kev thov. Nws kuj tseem muaj nyob rau hauv cov xim, varnishes thiab adhesives.

n-Heptane muaj tus lej octane ntawm 0, uas tau txhais thoob ntiaj teb. Qhov no ua rau siab -purity n-heptane (min. 99.75 %) yog thawj cov roj siv rau kev txiav txim siab octane tus naj npawb ntawm cov roj av hauv lub cav tshwj xeeb.

txog peb

Henan Gneebiotau tsim nyob rau hauv 2016, ua raws li lub tswv yim ntawm "cov khoom siv tshuaj lom neeg thoob ntiaj teb" thiab tsom mus rau qib siab -kev lag luam tshuaj lom neeg zoo. Lub tuam txhab feem ntau cuam tshuam cov khoom siv tshuaj lom neeg, xws li dichloromethane; methyl sulfoxide DMSO ( qib kev lag luam thiab kws tshuaj); ethylene glycol (MEG); p-Xylene, thiab lwm yam.

Tag nrho peb cov khoom siv tshuaj lom neeg tau txais cov ntawv pov thawj thoob ntiaj teb suav nrog REACH, ISO, FMQS, HALAL, thiab Halal ntawv pov thawj, kom ntseeg tau tias muaj txiaj ntsig zoo thiab kev lees paub thoob ntiaj teb, Peb muaj cov tsev khaws khoom hauv coreports xws li Qingdao, Tianiin, thiab Shanghai, nrog rau 15-hnub kev xa khoom xa tuaj.
