Sodium ethoxide (Sodium ethoxide 20% solution)
| ʻAno kemika | ʻO ka pauka keʻokeʻo a melemele paha;hygroscopic;pōʻeleʻele a popopo i ka ʻike ʻana i ka ea;decomposes i loko o ka wai e hana ana i ka sodium hydroxide a me ka ethanol;hoʻoheheʻe ʻia i loko o ka ethanol pono.ʻAʻole kūpono me nā mea hoʻoheheʻe chlorinated, moisture.Hoʻopili i ke kalapona mai ka lewa.Hiki ke ahi. | |
| Nā noi | Hoʻohana ʻia ka sodium ethoxide i ka synthesis organik no nā hopena condensation.He mea hoʻoikaika ia i nā ʻano hana kūlohelohe. Hoʻohana ʻia ka sodium ethoxide, 21% w/w i ka ethanol ma ke ʻano he kumu ikaika i ka synthesis organik.Loaʻa iā ia ka hoʻohana ʻana i nā hopena kemika like ʻole e like me ka condensation, esterification, alkoxylation a me ka etherifcation.Hoʻokomo ikaika ia i ka condensation Claisen, ka hopena o Stobbe a me ka hōʻemi Wolf-kishner.He mea hoʻomaka koʻikoʻi ia no ka hana ʻana o ka ethyl ester a me ka diethyl ester o ka malonic acid.Ma Williamson ether synthesis, hana ia me ka ethyl bromide e hana i diethyl ether. | |
