Txhais lus hais tias

Rooj mov

DMAC feem ntau yog siv los ua cov kuab tshuaj rau hluavtaws (acrylonitrile . Piv txwv li. Tam sim no, nws yog dav siv hauv cov tshuaj thiab tshuaj tua kab los ua ke cov tshuaj tua kab mob thiab tshuaj tua kab. Nws kuj tseem tuaj yeem siv los ua cov tshuaj tiv thaiv rau cov tshuaj tiv thaiv, cov kuab tshuaj electrolytic, thiab ntau yam ntawm crystalline cov kuab tshuaj ntxiv thiab cov nyom.

Kev piav txog

N, n-dimethylacetamide, tseem hu ua acyetlimethylas, lossis DMAC rau luv, yog solubanity tsw me me, thiab ntau ntawm cov khoom siv soluble. Nws tau dav dav nrog dej, cov khoom sib cai uas muaj ntxhiab, tshuaj tua kab, cov neeg muaj dej cawv, yog li nws tau siv dav ua cov kuab tshuaj thiab catalyst. Nyob rau hauv cov nqe lus ntawm cov kuab tshuaj, raws li kev daws teeb meem nrog lub siab npau npau, muaj kuab lom, nws tuaj yeem siv rau polyacryloniturin thiab lwm yam coploymers thiab lwm cov coploymers thiab cov caromic carboxylic acid microscent; Nyob rau hauv cov nqe lus ntawm catalyst, nws tuaj yeem siv nyob rau hauv cov txheej txheem ntawm cua sov urea los tsim alkhlide thiab halogenated alkyl los tsim alkyl alkyne, thiab cov tshuaj tiv thaiv ntawm organic halide thiab cyanate los tsim cov khoom lag luam isocyanate. N, n-Dimethylacetamide kuj tseem siv tau los ua cov huab cua rau electrolygy kuab thiab cov duab pleev xim nyoos, tshuaj tua kab thiab khoom siv. Expactact distillation distillation distillation rau cais cov styrene los ntawm C8 feem, thiab lwm yam.
