DMAC feem ntau yog siv los ua cov kuab tshuaj rau cov hluavtaws (acrylonitrile 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 cov kuab tshuaj nrog lub siab npau npau, lub teeb ci ntsa iab, cov khoom siv hluav taws xob, nws tuaj yeem siv tau rau cov kuab tshuaj thiab lwm yam coploymers thiab lwm cov coploymers thiab muaj ntxhiab carboxylic acid forment; Nyob rau hauv cov nqe lus ntawm catalyst, nws tuaj yeem siv nyob rau hauv cov txheej txheem ntawm cua sov urea los tsim alkhlenated alkyne, thiab cov tshuaj tiv thaiv ntawm cov organic halide thiab cyanate los tsim khoom 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.
