Kamar yadda acetylene aka shirya daga methane

Acetylene ne abu na ga aji na alkynes. A wasu kalmomin, da hydrocarbon wanda yana a cikin kowane kwayoyin sau uku bond. A wannan sinadaran dabara acetylene kamar haka: C ₂ H _2. A kanta, wannan abu ne mai colorless iskar gas, wanda shi ne da yawa m fiye da iska. Acetylene samu daga methane. The abu ne mai amsawa da kuma fashewar.

Yadda za a samu acetylene

Methane a cikin gida don samun acetylene ne da wuya sosai. A mafi sauki hanya domin kadaici na gas - wannan ruwa reacts tare da alli carbide. Mutane da yawa daga gare ku yiwuwa tuna da yadda za a jefa a puddles guda daga cikin abu da kuma abin da na dauki faruwa. An lura da m yi fito. Kamar yadda na alli carbide, sa'an nan shi a hankali narke, kafa wani babban adadin kumfa. A irin wannan dauki za a iya rubuta kamar:

CAC ₂ + 2h ₂ Ya = C ₂ H ₂ + Ca (OH) _2.

Mutane da yawa fasaha alli carbide da ake amfani, wanda ya ƙunshi babban adadin impurities. A sakamakon haka, na dauki kayan da ruwa ta saki mugun wari. Yana taso ne daga cikin samuwar, tare da qananan adadin acetylene gas mai guba vapors. Mafi sau da yawa shi ne phosphine, hydrogen sulfide, da sauransu. Wannan hanya ne ya fi kowa, kamar yadda ya samu acetylene daga methane mai yiwuwa ne kawai tare da musamman kayan aiki.

Shiri Industry

Yadda za a samu da acetylene daga methane a wani m yanayi? A halin yanzu yi amfani da daya kawai Hanyar - fatattaka. A lokacin shiri na acetylene aka kwashe decoupling -C-C. Wannan na faruwa a gaban catalysts kuma a isasshe high zazzabi daukan hotuna. Domin yana amfani da methane - iskar gas. Wannan shi ne wani m da kuma samuwa raw kayan. Yana da wannan dalilin cewa fatattaka ne mafi m Hanyar biyu ta fuskar tattalin arziki da kuma a zahiri.

Yadda aka fashe

Domin gudanar da hira da "methane - acetylene" a hanyoyi da dama. A cikin farko case, iskar gas da aka wuce ta pre-zafi lantarki. The zazzabi za a kai har zuwa 1600 ° C. Bayan dumama, m sanyaya auku. Na biyu Hanyar ta dogara ne a kan yin amfani da zafin rana da aka generated da m konewa na acetylene.

Reaction lissafi "methane - acetylene" an rubuta kamar haka:

1. A yanayin na: 2Tar ₄ = C ₂ H ₂ + 3H _2.

1. A hali II: 6SN ₄ + 4O ₂ = C ₂ H ₂ + 8H + 3SO ₂ + ₂ + CO 3H ₂ O.

Masana sun ba da shawarar yin amfani da ga ajiya na acetylene cylinders sanye take da bawuloli na tagulla. Lalle ne, a cikin abun da ke ciki na gami dauke da jan karfe. Tun acetylene chemically aiki, zai iya amsa tare da karfe. A sakamakon wannan nau'i m gishiri.

A amfani da acetylene

Acetylene - wani abu da ake amfani da ko'ina a daban-daban da masana'antu sassa. Mafi sau da yawa, wannan gas da ake amfani da a samar da ethyl barasa a matsayin babban albarkatun kasa. Bugu da kari, da acetylene da ake amfani da wasu iri roba, robobi da kuma acetic acid.

Active gas ne yadu amfani, da kuma a lokacin waldi, da kuma ma lokacin da yankan daban-daban karafa. Ya kamata a lura da cewa karfi harshen wuta da aka kafa a cikin hadawan abu da iskar shaka ta oxygen acetylene. Gas tushen ne isasshe haske a cikin fitilu na m irin. Bisa acetylene kayan nakiyoyi, wanda ake kara amfani da detonators.
