1,2-Dichloroethane CAS 107-06-2

piav qhia luv luv:

1,2-Dichloroethane yog cov xim tsis muaj xim, pob tshab oily kua nrog chloroform zoo li tsw thiab saj qab zib. Soluble nyob rau hauv dej txog 120 zaug, miscible nrog ethanol, chloroform thiab ether. Muaj peev xwm yaj cov roj thiab roj, roj, paraffin.
Feem ntau yog siv rau hauv kev tsim cov yas chloride, oxalic acid thiab ethylenediamine, thiab tseem tuaj yeem siv los ua cov kuab tshuaj, cov tshuaj fumigants, detergents, extraction agents, hlau degreasing agents, thiab lwm yam.
Txoj kev tsim khoom:
1. Direct synthesis txoj kev ntawm ethylene thiab chlorine: chlorine ethylene thiab chlorine nyob rau hauv 1,2-dichloroethane nruab nrab los tsim crude dichloroethane thiab ib tug me me npaum li cas ntawm polychlorides, ntxiv alkali thiab flash evaporate kom tshem tawm acidic tshuaj thiab ib co boiling tshuaj, ntxuav nrog dej. kom txog thaum nruab nrab, azeotropic lub cev qhuav dej, thiab distillation kom tau txais cov khoom tiav. 2. Ethylene oxychlorination method: Ethylene yog ncaj qha chlorinated nrog chlorine los ua dichloroethane. Cov hydrogen chloride rov qab los thaum lub sij hawm tawg ntawm dichloroethane los tsim cov yas chloride, cov pa roj carbon monoxide Chemicalbook (cua) thiab ethylene preheated rau 150-200 ° C yog dhau los ntawm tooj liab chloride catalyst loaded ntawm alumina ntawm lub siab ntawm 0.0683-0.1033MPa. , react ntawm qhov kub ntawm 200-250 ° C, thiab cov khoom crude yog txias (condensing feem ntau ntawm trichloroacetaldehyde thiab ib feem ntawm cov dej), pressurized, thiab refined kom tau cov khoom dichloroethane. 3. Txoj kev ncaj qha chlorination ntawm ethylene los ntawm cov roj av tawg los yog coke qhov cub. Tsis tas li ntawd, 1,2-dichloroethane kuj yog cov khoom siv los ntawm kev tsim cov chloroethanol thiab ethylene oxide.
