diethyl ethylidenemalonate (CAS#1462-12-0)

Intshayelelo

I-Diethyl malonate (i-diethyl malonate) yi-organic compound. Olu lulandelayo lulwazi malunga neempawu, ukusetyenziswa, iindlela zokulungiselela kunye nokhuseleko lwe-diethyl ethylene malonate:

Umgangatho:

Imbonakalo: Ulwelo olungenambala.

Ubuninzi: 1.02 g/cm³.

Ukunyibilika: I-Diethyl ethylene malonate iyanyibilika kwii-solvents ezininzi ze-organic ezifana ne-alcohol, i-ethers, kunye ne-esters.

Sebenzisa:

I-Diethyl ethylene malonate isoloko isetyenziswa njenge-reagent ebalulekileyo kwi-organic synthesis. Ingasetyenziselwa ukwenza iikhompawundi ezifana neeketoni, ii-ethers, iiasidi, njl.

I-Diethyl ethylene malonate ingasetyenziselwa njenge-solvent kunye ne-catalyst.

Indlela:

I-Diethyl ethylene malonate inokuqulunqwa ngokusabela kwe-ethanol kunye ne-anhydride ye-malonic phambi kwe-catalyst ye-asidi. Iimeko zokusabela ziqhelekileyo ubushushu obuphezulu kunye noxinzelelo oluphezulu.

Ulwazi ngoKhuseleko:

I-Diethyl ethylene malonate lulwelo olunokutsha, olunokwenza lula umlilo xa luvezwe kwidangatye elivulekileyo okanye ubushushu obuphezulu. Kufuneka igcinwe kwaye isetyenziswe kude nemithombo yomlilo kunye neendawo zokushisa okuphezulu.

Kufuneka kuthathelwe ingqalelo ukuthintela ukudibana nolusu, amehlo kunye nepheshana lokuphefumla, kunye nezixhobo zokuzikhusela ezinje ngeeglavu zokhuselo, iiglavu kunye nemaski kufuneka zinxitywe xa kukho imfuneko.

Ukunyamekela kufuneka kuthathwe ukuthintela ukuvuza ngexesha lokusetyenziswa kunye nokugcinwa, kunye nokuphepha ukusabela ngee-oxidants ezinamandla kunye ne-acids eqinile.

IPhepha leDatha yoKhuseleko (MSDS) yemveliso kufuneka ifundwe ngolwazi oluthe vetshe ngokhuseleko phambi kokusetyenziswa.
