Katundu wakuthupi

Phewa mankhwala a siliva oxide ndi Agáo, wokhala ndi kulemera kwa 231.74. Brown kapena imvi Kusungunuka pang'ono m'madzi, kusungunuka kwambiri mu nitric acid, ammonia, sodium thiosulpate, ndi potaziyamu kum'mawa. Pamene Amoni anagwiritsa ntchito, ziyenera kuthandizidwa pa nthawi yake. Kuwonekera kwa nthawi yayitali kumatha kuthira makristali akuda kwambiri - siliva nitride kapena sulfite sulfite sulfite. Ogwiritsidwa ntchito ngati oxidant ndi galasi lagalasi. Yakonzedwa ndi siliva yasiliva yothetsera sodium hydroxide yankho.

Brown Crystalline kapena ufa wakuda. Kutalika kwa mgwirizano (AG o) 205pm. Kuwonongeka kumapeto madigiri 250, kumasula mpweya. Kachulukidwe 7.220g / masentimita 25 (madigiri 25). Kuwala pang'onopang'ono kumawola. Muzichita ndi sulfuric acid kuti apange sulfate yasiliva. Kusungunuka pang'ono m'madzi. Sungunulani mu Amoni madzi, sodium hydroxide Solution, kuchepetsa nitric acid, ndi sodium thiosulfate yankho. Insuliluble mu ethanol. Yakonzedwa ndi siliva yasiliva yothetsera sodium hydroxide yankho. Onyowa AG2o amagwiritsidwa ntchito ngati chothandizira polowetsa ma galogens okhala ndi magulu a hydroxyl mu synthesis. Amagwiritsidwanso ntchito ngati chinthu chosungira ndi zida zamagetsi.

 

Katundu wa mankhwala

Onjezani yankho la cautic ku yankho la siliva nitrate yankho kuti mupeze. Choyamba, yankho la siliva hydroxide ndi nitrate limapezeka, ndipo siliva hydroxide amawongolera kukhala siliva ndi madzi kutentha. Oxide oxide amayamba kuwola atatenthedwa mpaka 250 ℃, amatulutsa mpweya wabwino, ndikuwola mofulumira 300 ℃. Kusungunuka pang'ono m'madzi, koma kusungunuka kwambiri pamankhwala monga Nitric acid, ammonia, potaziyamu cyanide, ndi sodium thiosulpate. Pambuyo pakuwonekera kwa nthawi yayitali kwa Ammonia, makristali amphamvu kwambiri nthawi zina amatha kutenthetsa - mwina siliva nitride kapena siliva wainide. Mu synthesis synthesis, magulu a hydroxyl nthawi zambiri amagwiritsidwa ntchito kusintha ma halogens kapena ngati oxidants. Itha kugwiritsidwanso ntchito ngati colorant mu malonda agalasi.

 

Njira Yokonzekera

Oxide oxide otuwa amatha kupezeka polemba alkali zitsulo za alkroxide ndi siliva nitrate. [1] Zomwe zimachitika koyamba zimatulutsa siliva wosakhazikika kwambiri, womwe nthawi yomweyo umawola kuti upeze madzi ndi siliva. Pambuyo pakutsuka kumtunda, iyenera kuwuma pasanathe 85 ° C, koma ndizovuta kwambiri kuti muchotse madzi ochepa kuchokera ku siliva kumapeto chifukwa pamene kutentha kumawonjezeka, ma siliva amawonjezeka. 2 AL- → 2 Alefh → AG2o + h2o.

 

Kugwiritsa Ntchito Zoyambira

Makamaka monga chothandizira pamankhwala amchere. Amagwiritsidwanso ntchito ngati chida choteteza, chida chamagetsi, cotorant colorant, ndi wothandizira wopera. Ntchito zamankhwala komanso ngati wothandizira wagalasi, woyeretsa komanso woyeretsa madzi; Ntchito ngati kupukutira ndi kukongoletsa kwagalasi.

 

Ntchito

Ma siliva oxide ndi zinthu zamagetsi za mabatire asiliva ali. Ndiwonso malo ofooka komanso ofooka mu synthesis synthesis, omwe angachitire ndi Imayimazole Sctts ndi Benzimidazole mchere kuti apange Azenes. Itha kusintha masikono osakhazikika monga cyclooctile kapena acetonitrile ngati njira yosinthira ma carbene kuti isinthe masinthidwe azitsulo za Carbenes. Kuphatikiza apo, siliva oxide amatha kutembenuka ma bromic ndi kuyamwa mu mowa wochepa kutentha komanso pamaso pa nthunzi yamadzi. Amagwiritsidwa ntchito molumikizana ndi iodomethane monga metylat reage ya kusanthula kwa shuga ndi hoffman kuchotsedwa kwa ma eldehyd a Aldeyydes ku Carboxyydic Acids.
