Sodium ethoxide (Sodium ethoxide 20% yankho)
| Chemical chilengedwe | ufa woyera kapena wachikasu;hygroscopic;imachita mdima ndi kuwola ikakumana ndi mpweya;amawola m'madzi kupanga sodium hydroxide ndi Mowa;amasungunuka mu ethanol mtheradi. Amachita mwankhanza ndi zidulo, madzi.Zosagwirizana ndi chlorinated solvents, chinyezi.Imamwa mpweya woipa kuchokera mumlengalenga.Zoyaka kwambiri. | |
| Mapulogalamu | Sodium ethoxide imagwiritsidwa ntchito popanga organic synthesis ya condensation reaction.Komanso ndi chothandizira ambiri organic zimachitikira. Sodium ethoxide, 21% w/w mu ethanol imagwiritsidwa ntchito ngati maziko amphamvu mu kaphatikizidwe ka organic.Iwo amapeza ntchito zosiyanasiyana zimachitikira mankhwala monga condensation, esterification, alkoxylation ndi etherifcation.Imakhudzidwa kwambiri ndi Claisen condensation, Stobbe reaction ndi Wolf-kishner kuchepetsa.Ndikofunikira poyambira kaphatikizidwe ka ethyl ester ndi diethyl ester ya malonic acid.Mu Williamson ether synthesis, imakumana ndi ethyl bromide kupanga diethyl ether. | |
| Alumali moyo | Malinga ndi zomwe takumana nazo, mankhwalawa amatha kusungidwa kwa 12miyezi kuyambira tsiku lobadwa ngati asungidwa m'mitsuko yosindikizidwa mwamphamvu, yotetezedwa ku kuwala ndi kutentha ndikusungidwa pa kutentha kwapakati pa 5 -30°C. | |

Chitetezo
Pogwira ntchitoyi, chonde tsatirani upangiri ndi zidziwitso zomwe zaperekedwa patsamba lachitetezo ndikuwona njira zodzitetezera komanso zaukhondo wapantchito zokwanira kugwiritsa ntchito mankhwala.
Zindikirani
Zomwe zili m’bukuli n’zozikidwa pa zimene tikudziwa komanso zimene takumana nazo panopa.Poganizira zinthu zambiri zomwe zingakhudze kukonza ndi kugwiritsa ntchito mankhwala athu, izi sizimachotsera mapurosesa kuti azichita okha kufufuza ndi kuyesa;komanso deta iyi sikutanthauza chitsimikizo cha zinthu zina, kapena kukwanira kwa chinthucho pazifukwa zinazake.Mafotokozedwe aliwonse, zojambula, zithunzi, deta, kuchuluka, zolemera, ndi zina zotero zomwe zaperekedwa apa zingasinthe popanda chidziwitso choyambirira ndipo sizipanga mgwirizano wogwirizana wa malonda.Mgwirizano wamakontrakitala wa chinthucho umachokera ku ziganizo zomwe zanenedwa muzotsatira zamalonda.Ndi udindo wa wolandira katundu wathu kuonetsetsa kuti ufulu wa eni eni ndi malamulo omwe alipo kale akutsatiridwa.
