i-diethyl ethylidenemalonate (CAS#1462-12-0)

Isingeniso

I-Diethyl malonate (i-diethyl malonate) iyinhlanganisela yezinto eziphilayo. Okulandelayo ulwazi mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela nokuphepha kwe-diethyl ethylene malonate:

Ikhwalithi:

Ukubukeka: Uketshezi olungenambala.

Ukuminyana: 1.02 g/cm³.

I-Solubility: I-Diethyl ethylene malonate iyancibilika kuzincibilikisi eziningi eziphilayo ezifana notshwala, ama-ether, nama-esters.

Sebenzisa:

I-Diethyl ethylene malonate ivame ukusetshenziswa njenge-reagent ebalulekile ku-organic synthesis. Ingasetshenziselwa ukuhlanganisa izinhlanganisela ezifana nama-ketone, ama-ether, ama-asidi, njll.

I-Diethyl ethylene malonate ingasetshenziswa njenge-solvent kanye ne-catalyst.

Indlela:

I-Diethyl ethylene malonate ingahlanganiswa ngokusabela kwe-ethanol kanye ne-anhydride ye-malonic phambi kwe-catalyst ye-asidi. Izimo zokusabela ngokuvamile izinga lokushisa eliphezulu kanye nokucindezela okukhulu.

Ulwazi Lokuphepha:

I-Diethyl ethylene malonate iwuketshezi oluvuthayo, olungadala umlilo kalula lapho luvezwe elangabini elivulekile noma izinga lokushisa eliphezulu. Kufanele igcinwe futhi isetshenziswe kude nemithombo yomlilo kanye nezindawo ezinokushisa okuphezulu.

Kufanele kuqashelwe ukugwema ukuthintana nesikhumba, amehlo kanye nemigudu yokuphefumula, futhi izinto zokuzivikela ezifana namagilavu ​​okuzivikela, izibuko kanye namamaski kufanele kugqokwe lapho kunesidingo.

Ukunakekela kufanele kuthathwe ukuze kuvinjelwe ukuvuza ngesikhathi sokusetshenziswa nokugcinwa, nokugwema ukusabela ngama-oxidants aqinile nama-asidi aqinile.

I-Safety Data Sheet (MSDS) yomkhiqizo kufanele ifundwe ukuze uthole ulwazi oluningiliziwe lokuphepha ngaphambi kokusetshenziswa.
