diethyl ethylidenemalonate（CAS#1462-12-0）

Hoʻolauna

ʻO Diethyl malonate (diethyl malonate) he mea hoʻohuihui. Eia ka ʻike e pili ana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka palekana o ka diethyl ethylene malonate:

ʻAno maikaʻi:

Ke ʻano: wai kala ʻole.

Māmā: 1.02 g/cm³.

Solubility: Hiki ke hoʻoheheʻe ʻia ka Diethyl ethylene malonate i loko o nā mea hoʻoheheʻe kūlohelohe e like me nā ʻawaʻawa, eter, a me nā esters.

E hoʻohana:

Hoʻohana pinepine ʻia ʻo Diethyl ethylene malonate ma ke ʻano he reagent koʻikoʻi i ka synthesis organik. Hiki ke hoʻohana ʻia e synthesize i nā pūhui e like me ketones, ethers, acids, etc.

Hiki ke hoʻohana ʻia ʻo Diethyl ethylene malonate ma ke ʻano he solvent a me ka catalyst.

Hanana:

Hiki ke hoʻohui ʻia ʻo Diethyl ethylene malonate e ka hopena o ka ethanol a me ka malonic anhydride i mua o kahi catalyst acid. ʻO ke ʻano o ka hopena he wela kiʻekiʻe a me ke kaomi kiʻekiʻe.

ʻIke palekana:

ʻO ka Diethyl ethylene malonate he wai lapalapa, hiki ke hana maʻalahi i ke ahi ke ʻike ʻia i ka lapalapa a i ʻole ka wela wela. Pono e mālama ʻia a hoʻohana ʻia mai nā kumu ahi a me nā wahi wela.

Pono e mālama ʻia e pale aku i ka hoʻopili ʻana me ka ʻili, nā maka a me nā ʻāpana hanu, a pono e hoʻohana ʻia nā mea pale pilikino e like me nā mīkina lima pale, nā maka aniani a me nā masks inā pono.

Pono e mālama i ka leakage i ka wā o ka hoʻohana ʻana a me ka mālama ʻana, a e pale aku i ka pane ʻana me nā oxidants ikaika a me nā waikawa ikaika.

Pono e heluhelu ʻia ka Pepa ʻIkepili Palekana (MSDS) o ka huahana no ka ʻike kikoʻī palekana ma mua o ka hoʻohana ʻana.
