diethyl ethylidenemalonate (CAS#1462-12-0)

Mawu Oyamba

Diethyl malonate (diethyl malonate) ndi organic pawiri. Zotsatirazi ndizo zokhudzana ndi katundu, ntchito, njira zokonzekera ndi chitetezo cha diethyl ethylene malonate:

Ubwino:

Maonekedwe: Madzi opanda mtundu.

Kachulukidwe: 1.02 g/cm³.

Kusungunuka: Diethyl ethylene malonate imasungunuka mu zosungunulira zambiri monga ma alcohols, ethers, ndi esters.

Gwiritsani ntchito:

Diethyl ethylene malonate nthawi zambiri amagwiritsidwa ntchito ngati reagent yofunika mu organic synthesis. Itha kugwiritsidwa ntchito popanga zinthu monga ma ketoni, ethers, acids, etc.

Diethyl ethylene malonate angagwiritsidwe ntchito ngati zosungunulira ndi chothandizira.

Njira:

Diethyl ethylene malonate imatha kupangidwa ndi zomwe ethanol ndi malonic anhydride pamaso pa chothandizira cha asidi. The anachita zinthu zambiri kutentha ndi kuthamanga.

Zambiri Zachitetezo:

Diethyl ethylene malonate ndi madzi oyaka, omwe amatha kuyambitsa moto mosavuta akakhala pamoto kapena kutentha kwambiri. Iyenera kusungidwa ndi kugwiritsidwa ntchito kutali ndi magwero a moto ndi malo otentha kwambiri.

Chisamaliro chiyenera kutengedwa kuti musakhudzidwe ndi khungu, maso ndi kupuma, komanso zida zodzitetezera monga magolovesi otetezera, magalasi ndi masks ayenera kuvala ngati kuli kofunikira.

Chisamaliro chiyenera kutengedwa kuti chiteteze kutayikira panthawi yomwe mukugwiritsa ntchito ndikusunga, komanso kupewa kuchitapo kanthu ndi ma okosijeni amphamvu ndi ma asidi amphamvu.

Mapepala a Chitetezo cha Chitetezo (MSDS) ayenera kuwerengedwa kuti mudziwe zambiri zachitetezo musanagwiritse ntchito.
