CAS No. 74-86-2 Ethyne Supplier. High purity Ethyne lag luam wholesale.
CAS Naj Npawb 74-86-2 sib raug rau Ethyne, feem ntau hu ua Acetylene, roj tsis muaj xim, nplaim taws tau siv dav hauv ntau yam kev lag luam. Nov yog qee cov yam ntxwv tseem ceeb ntawm acetylene:
Cov roj formula: C2H2
Lub cev lub cev: Ntawm qhov ntsuas kub thiab siab (STP), acetylene yog roj. Nws feem ntau yog khaws cia yaj hauv cov kuab tshuaj xws li acetone hauv lub tog raj kheej siab lossis tsim rau ntawm qhov chaw rau kev siv tam sim.
Molecular Luj: Kwv yees li 26.04 g / mol.
Boiling Point: -83.8 ° C (-120.84 ° F) ntawm 1 cua.
Melting Point: -81.8 ° C (-115.24 ° F).
Ceev: Nyob ib ncig ntawm 1.17 kg / m³ ntawm STP, ua rau nws me ntsis sib zog dua huab cua.
Vapor Pressure: Siab heev, yuav tsum tau txiav txim siab tshwj xeeb cia.
Solubility: Me ntsis soluble hauv dej tab sis ntau soluble hauv cov kuab tshuaj organic xws li acetone thiab ethanol.
Flammability thiab Reactivity: Acetylene yog cov nplaim taws heev thiab tawg thaum sib xyaw nrog huab cua hauv qee qhov kev faib ua feem (nruab nrab ntawm 2.5% thiab 82%). Nws muaj zog heev nrog tooj liab, nyiaj, mercury, thiab lawv cov alloys, tsim cov khoom tawg; Yog li, acetylene tuav cov cuab yeej yuav tsum tsis muaj cov ntaub ntawv no.
Kev siv Acetylene:
Vuam thiab Txiav: Acetylene yog cov roj roj ntawm kev xaiv hauv oxy-acetylene torches vim nws cov hluav taws kub kub, ua rau nws tsim nyog rau kev txiav hlau, vuam, thiab brazing.
Chemical Synthesis: Siv los ua cov khoom siv raw hauv kev tsim ntau yam tshuaj, suav nrog vinyl acetate, acetic acid, thiab chloroprene.
Teeb pom kev zoo: Keeb kwm, nws tau siv nyob rau hauv carbide teeb rau illumination.
Kev kho cua sov: Muab cov cua kub kub rau kev sib tsoo, tawv tawv, thiab lwm yam kev kho cua sov.
Kev txiav txim siab txog kev nyab xeeb:
Hluav taws kub heev thiab tawg phom sij: Yuav tsum tau ua raws li nruj me ntsis rau kev tuav thiab cia cov txheej txheem tiv thaiv ignition.
Toxicity: Thaum acetylene nws tus kheej tsis muaj tshuaj lom heev, nws cov khoom siv hluav taws xob tuaj yeem ua rau muaj kev phom sij, tshwj xeeb tshaj yog nyob rau hauv qhov chaw tsis zoo.
Copper-Free Equipment: Txhua yam khoom siv nrog acetylene yuav tsum tau ua los ntawm cov ntaub ntawv uas tsis cuam tshuam nrog nws, xws li stainless hlau los yog tooj dag uas tsis muaj ntau tshaj li cov tooj liab.
Thaum nrhiav tus neeg muag khoom ntawm acetylene, nrhiav cov khoom siv roj muaj npe lossis cov chaw muag roj tshwj xeeb uas paub zoo txog kev tuav pov hwm kev nyab xeeb, khaws cia, thiab kev thauj mus los ntawm cov pa roj no. Lawv yuav tsum muab cov thooj voos kheej kheej uas muaj cov acetylene yaj los yog muab cov txheej txheem acetylene nyob rau ntawm qhov chaw, ua kom muaj kev ua raws li tag nrho cov cai tswj kev nyab xeeb thiab kev ua haujlwm zoo tshaj plaws.
