Sodium ethoxide (Sodium ethoxide 20% yankho)
| Chilengedwe cha mankhwala | Ufa woyera kapena wachikasu; wosawoneka bwino; umadetsedwa ndi kuwola ukakumana ndi mpweya; umawola m'madzi ndikupanga sodium hydroxide ndi ethanol; umasungunuka mu ethanol yeniyeni. Umayankha mwamphamvu ndi ma acid, madzi. Sigwirizana ndi zosungunulira za chlorine, chinyezi. Umayamwa carbon dioxide kuchokera mumlengalenga. Umayaka kwambiri. | |
| Mapulogalamu | Sodium ethoxide imagwiritsidwa ntchito popanga zinthu zachilengedwe kuti ipange zinthu zoundana. Imagwiranso ntchito ngati chothandizira pa zinthu zambiri zachilengedwe. Sodium ethoxide, 21% w/w mu ethanol imagwiritsidwa ntchito ngati maziko olimba mu kapangidwe ka organic. Imagwiritsidwa ntchito muzochita zosiyanasiyana zamakemikolo monga condensation, esterification, alkoxylation ndi etherifcation. Imagwira ntchito kwambiri mu Claisen condensation, Stobbe reaction ndi Wolf-kishner reduction. Ndi chinthu chofunikira poyambira kupanga ethyl ester ndi diethyl ester ya malonic acid. Mu Williamson ether synthesis, imayanjana ndi ethyl bromide kupanga diethyl ether. | |
| Nthawi yosungira zinthu | Malinga ndi zomwe takumana nazo, mankhwalawa akhoza kusungidwa kwa masiku 12.miyezi kuyambira tsiku loperekedwa ngati zasungidwa m'zidebe zotsekedwa bwino, zotetezedwa ku kuwala ndi kutentha ndikusungidwa kutentha pakati pa 5 -30°C. | |

Chitetezo
Mukamagwiritsa ntchito mankhwalawa, chonde tsatirani malangizo ndi chidziwitso chomwe chaperekedwa mu pepala la deta yachitetezo ndipo tsatirani njira zodzitetezera komanso zaukhondo kuntchito zoyenera pogwiritsira ntchito mankhwala.
Zindikirani
Deta yomwe ili m'buku lino imachokera ku chidziwitso chathu chamakono komanso zomwe takumana nazo. Poganizira zinthu zambiri zomwe zingakhudze kukonza ndi kugwiritsa ntchito malonda athu, deta iyi siimasula opanga kuti achite kafukufuku wawo ndi kuyesa; deta iyi sikutanthauza chitsimikizo chilichonse cha katundu wina, kapena kuyenerera kwa malondawo pacholinga china. Mafotokozedwe aliwonse, zojambula, zithunzi, deta, kuchuluka, kulemera, ndi zina zotero zomwe zaperekedwa pano zitha kusintha popanda chidziwitso cham'mbuyomu ndipo sizipanga mtundu wa malonda womwe wavomerezedwa. Ubwino wa malonda womwe wavomerezedwa umachokera kokha ku mawu omwe aperekedwa mu ndondomeko ya malonda. Ndi udindo wa wolandira malonda athu kuonetsetsa kuti ufulu uliwonse wa mwiniwake ndi malamulo ndi malamulo omwe alipo akutsatiridwa.
