Monga acetylene kukonzekera kwa dziko

Acetylene ndi mankhwala a kalasi ya alkynes. Mu mawu ena, hydrocarbon amene ali uliwonse molekyulu nsinga patatu. Mu ichi mankhwala chilinganizo acetylene motere: C ₂ H _2. Palokha, mankhwala ndi mpweya colorless, lomwe ndi opepuka kuposa mpweya. Acetylene kuwapeza dziko. thunthu ndi zotakasika ndi zachiwawa.

Kodi kupeza acetylene

Wa dziko kunyumba kuti akatenge acetylene zovuta. The njira yosavuta kwa kudzipatula mpweya - madzi amachitira ndi carbide calcium. Ambiri a inu mwina kumbukirani momwe kuponya mu zidutswa puddles wa chinthu ndi zimene anachita amapezeka. Inafotokoza za hiss mofulumira. Koma kashiamu carbide, ndiye pang'onopang'ono kusungunuka, kupanga kuchuluka kwa thovu. A zotani zofanana akhoza kulembedwa monga:

CaC ₂ + 2H ₂ O = C ₂ H ₂ + Ca (o) _2.

Ambiri luso kashiamu carbide ntchito, muli wambirimbiri zosafunika. Motero, zinthu zimachitika ndi madzi akumasula fungo loipa. Vutolo limachitika kwa mapangidwe, pamodzi ndi zazing'ono kuchuluka kwa acetylene mafuta nthunzi poizoni. Nthawi zambiri ndi phosphine, sulfide wa hydrogen, ndi zina zotero. Njira imeneyi ndi ambiri, monga kupeza acetylene ku dziko zimatheka ndi zipangizo zina zapadera.

Kukonzekera Makampani

Kodi kutenga acetylene ku dziko chilengedwe mafakitale? Panopa ntchito njira imodzi yokha - akulimbana. Pa yokonza acetylene ikuchitika decoupling -C-C. Izi zimachitika mu kukhalapo kwa catalysts ndi pa kukhudzana mokwanira mkulu kutentha. Pakuti amagwiritsa dziko - gasi. Ichi ndi zotsika mtengo komanso zosavuta kupeza zipangizo. Pachifukwa ichi kuti akulimbana ndi njira lanzeru zachuma ndi mwaukadaulo.

Kodi losweka

Kuti akwanitse kutembenuka kwa "dziko - acetylene" m'njira zingapo. Mbali yoyamba, gasi anadutsa elekitirodi chisanadze otentha. Kutentha angafikire ku 1600 ° C. Pambuyo Kutentha, kuzirala mofulumira amapezeka. Yachiwiri njira zachokera ntchito kutentha ndi kwaiye kuyaka tsankho la acetylene.

Chisoni aone kuti pali "dziko - acetylene" zinalembedwa motere:

1. Ndikakulangizani: 2 Mbiri ₄ = C ₂ H ₂ + 3H _2.

1. Pankhaniyi II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3SO ₂ + ₂ NKHA + 3H ₂ O.

Akatswiri musati amalangiza kuti agwiritse ntchito kusungiramo zonenepa acetylene okonzeka ndi mavavu zamkuwa. Ndithudi, zikuchokera kwa aloyi munali mkuwa. Popeza acetylene mankhwala yogwira, akhoza kutani ndi zitsulo. Chifukwa cha mchere mawonekedwe zachiwawa.

Ntchito acetylene

Acetylene - mankhwala kuti chimagwiritsidwa ntchito zamanja zosiyanasiyana mafakitale. Nthawi zambiri, gasi ichi ntchito yopanga ethyl mowa nkhani yaikulu yaiwisi. Komanso, acetylene ntchito mitundu ina ya labala, mapulasitiki acid acetic.

gasi yogwira chimagwiritsidwa ntchito kwambiri, ndi pa kuwotcherera, komanso pamene kudula zitsulo zosiyana siyana. Tikumbukenso kuti lawi amphamvu aumbike mwa makutidwe ndi okosijeni ndi mpweya acetylene. Mpweya gwero ndi kuwala mokwanira owala mu nyali ya mtundu yoyenda yokha. Yachokera acetylene zokolola mabomba, amene anapitiriza ntchito ngati detonators.
