Kusanthula mwatsatanetsatane kuwira kwa methanol
Methanol ndi imodzi mwazinthu zofunika kwambiri zopangira mankhwala, ndipo imagwiritsidwa ntchito kwambiri ngati mafuta, zosungunulira komanso kaphatikizidwe ka mankhwala. Mu pepala ili, tidzasanthula mwatsatanetsatane nkhani ya "Methanol Boiling Point", ndikukambirana mozama zakuthupi za methanol, zomwe zimakhudza kuwira kwake komanso kufunikira kwake pamafakitale.
The zofunika thupi katundu methanol
Methanol, yomwe imadziwikanso kuti mowa wamatabwa kapena mzimu wamatabwa, mankhwala a CH₃OH, ndiye mowa wosavuta kwambiri. Monga madzi opanda mtundu, omwe amatha kuyaka, methanol ndi yotentha kwambiri komanso ndi poizoni kwambiri. Kuwira kwake ndi gawo lofunikira pakumvetsetsa za methanol. Pamphamvu ya mumlengalenga, methanol imakhala ndi kuwira kwa 64.7 ° C (148.5 ° F), zomwe zimapangitsa kuti zisawonongeke kutentha kwapakati. Choncho, pogwira ndi kusunga methanol, ndikofunika kuganizira za kusinthasintha kwake ndi kuyaka kwake ndi kutenga njira zoyenera zotetezera.
Zomwe Zimakhudza Kutentha kwa Methanol
Pali zinthu zingapo zomwe ziyenera kuganiziridwa pomvetsetsa nkhani ya "methanol boiling point". Maselo a methanol amatsimikizira kuwira kwake kochepa. Molekyu ya methanol imakhala ndi gulu la methyl (CH₃) ndi gulu la hydroxyl (OH) ndipo imakhala ndi kulemera kochepa. Chifukwa cha kukhalapo kwa hydrogen kugwirizana mu gulu la hydroxyl, izi zimakweza kuwira kwake pang'ono, koma zimakhala zotsika kwambiri kuposa zakumwa zina zomwe zimakhala ndi mamolekyu apamwamba kwambiri.
Zinthu zakunja monga kusintha kwa kuthamanga kungakhudzenso kuwira kwa methanol. Pansi pazifukwa zotsika, malo otentha a methanol amachepa, pomwe pansi pazovuta kwambiri, amawonjezeka. Chifukwa chake, pangakhale kofunikira kuwongolera kutuluka kwa methanol ndi njira yotsitsimutsa posintha kupanikizika munjira zosiyanasiyana zamafakitale.
Kufunika kwa methanol kuwira mfundo mu ntchito mafakitale
Malo otentha a methanol ndi ofunikira kuti agwiritsidwe ntchito popanga mankhwala. Mwachitsanzo, popanga methanol ndi distillation, ndikofunikira kuwongolera kutentha koyenera ndi kukakamiza kwa kulekanitsa bwino komanso kuyeretsa methanol. Chifukwa cha kuwira kwake kochepa, methanol imatha kupangidwa ndi mpweya pogwiritsa ntchito zida zotenthetsera wamba, zomwe zimakhala zopindulitsa pakupulumutsa mphamvu zamagetsi.
Methanol otsika kuwira malo kumapangitsanso kukhala bwino zosungunulira, makamaka ntchito zimene zimafunika nthunzi nthunzi mofulumira, monga utoto ndi zotsukira. Pogwiritsa ntchito, kutentha ndi mpweya wabwino wa malo ogwira ntchito ziyenera kuyang'aniridwa mosamalitsa kuti muteteze kuwonjezereka kwa nthunzi ya methanol, motero kupewa moto kapena zoopsa za thanzi.
Mapeto
Kuchokera pa zomwe tafotokozazi, zikuwoneka kuti kumvetsetsa "kuwira kwa methanol" ndikofunikira kuti methanol ikhale yotetezeka komanso yogwira ntchito m'mafakitale. The kuwira mfundo methanol osati zimakhudza katundu wake thupi ndi zikhalidwe ntchito, komanso mwachindunji zokhudzana ndi kusankha ndi ntchito zosiyanasiyana mankhwala. Kudziwa kumeneku kumathandizira kukhathamiritsa njira zamakampani, kupulumutsa mphamvu ndikuwonjezera kupanga bwino.
