Kev siv
Ib qho txiaj ntsig tseem ceeb ntawm DMC yog nws lub peev xwm los hloov phosgene ua tus neeg sawv cev carbonylating, muab kev nyab xeeb dua thiab muaj kev nyab xeeb dua ib puag ncig. Phosgene ua rau muaj kev pheej hmoo loj rau tib neeg kev noj qab haus huv thiab ecosystems vim nws toxicity. Los ntawm kev siv DMC es tsis txhob siv phosgene, cov tuam txhab lag luam tuaj yeem tsis tsuas yog txhim kho cov qauv kev nyab xeeb, tab sis kuj tseem ua rau muaj kev nyab xeeb thiab huv si.
Tsis tas li ntawd, DMC tuaj yeem ua ib qho kev hloov pauv zoo rau tus neeg sawv cev methylating dimethyl sulfate. Dimethyl sulfate yog ib qho tshuaj lom neeg uas ua rau muaj kev phom sij loj rau cov neeg ua haujlwm thiab ib puag ncig. Siv DMC ua tus neeg sawv cev methylating tshem tawm cov kev pheej hmoo no thaum muab cov txiaj ntsig sib piv. Qhov no ua rau DMC zoo tagnrho rau kev lag luam tsim tshuaj, agrochemicals, thiab lwm yam methyl-critical chemicals.
Ntxiv rau qhov zoo li hais saum toj no, DMC kuj tseem ua tau zoo raws li cov kuab tshuaj lom neeg tsawg, ua rau nws muaj kev xaiv zoo rau ntau yam kev siv. Nws cov tshuaj toxicity tsawg ua kom muaj kev nyab xeeb ntawm kev ua haujlwm, txo qhov kev pheej hmoo ntawm cov neeg ua haujlwm thiab cov neeg siv khoom raug rau cov khoom phom sij. Tsis tas li ntawd, DMC qhov zoo heev solubility thiab broad compatibility nrog ntau yam ntaub ntawv ua rau nws muaj nuj nqis muaj nyob rau hauv roj av additive manufacturing. Siv DMC ua cov kuab tshuaj rau cov roj additives txhim kho tag nrho cov combustion efficiency ntawm roj av, uas txo emissions thiab txhim kho lub cav kev ua tau zoo.
Hauv kev xaus, dimethyl carbonate (DMC) yog ntau yam thiab muaj txiaj ntsig zoo rau cov tshuaj sib xyaw ua ke. Nws txoj kev nyab xeeb, yooj yim, tsis muaj tshuaj lom thiab ua tau zoo ua rau DMC zoo tagnrho rau ntau yam kev siv. Los ntawm kev hloov phosgene thiab dimethyl sulfate, DMC muaj kev nyab xeeb, kev xaiv ntsuab dua yam tsis muaj kev cuam tshuam kev ua haujlwm. Txawm hais tias siv los ua tus neeg sawv cev carbonylating, methylating tus neeg sawv cev, lossis cov kuab tshuaj lom neeg tsawg, DMC yog cov kev daws teeb meem zoo rau kev lag luam nrhiav kev txhim kho cov khoom thiab cov txheej txheem thaum txo kev cuam tshuam ib puag ncig.
