Kachulukidwe ka Ethyl Acetate: Kusanthula Kwakukulu ndi Kugwiritsa Ntchito Mwanzeru
Ethyl Acetate ndi wamba organic zosungunulira ntchito m'madera osiyanasiyana mafakitale ndi labotale. Kumvetsetsa kachulukidwe ka Ethyl Acetate sikofunikira kokha pakupanga mankhwala, komanso kumathandizira kukhathamiritsa kwake muzochitika zosiyanasiyana zogwiritsira ntchito. M'nkhaniyi, tikambirana za kuchuluka kwa ethyl acetate ndi zinthu zomwe zikukhudzidwa kuti zikuthandizeni kumvetsetsa bwino katundu wakuthupi.
Tanthauzo la Kachulukidwe ka Ethyl Acetate
Kuchuluka kwa ethyl acetate ndi kuchuluka kwa voliyumu ya ethyl acetate pa kutentha komwe kumaperekedwa ndi kukakamizidwa. Nthawi zambiri, kachulukidwe amayesedwa mu g/cm³ (ma gramu pa kiyubiki centimita) kapena kg/m³ (makilogramu pa kiyubiki mita). Kwa iwo omwe amagwira ntchito m'makampani opanga mankhwala, deta yolondola ya kachulukidwe ka ethyl acetate ingathandize kuwerengera molondola kagwiritsidwe ntchito ka zinthu, kukhathamiritsa njira ndikuwonetsetsa kuti zinthu zili bwino.
Makhalidwe enieni a kachulukidwe ka ethyl acetate
Pamikhalidwe yokhazikika (20°C, 1 atmosphere), kuchulukira kwa ethyl acetate ndi pafupifupi 0.902 g/cm³. Mtengo uwu umatanthauza kuti cubic centimita iliyonse ya ethyl acetate imalemera pafupifupi 0.902 magalamu. Ndikofunika kuzindikira kuti kachulukidwe amasiyanasiyana ndi kutentha. Kutentha kumawonjezeka, mphamvu yamadzimadzi nthawi zambiri imakula, zomwe zimapangitsa kuti kachulukidwe kakang'ono kakhale kochepa. Choncho, zotsatira za kusintha kwa kutentha kwa malo ogwirira ntchito pa kachulukidwe ka ethyl acetate ziyenera kuganiziridwa popanga mawerengedwe olondola.
Zinthu zomwe zimakhudza kachulukidwe wa ethyl acetate
Kutentha: Kutentha ndi chimodzi mwazinthu zazikulu zomwe zimakhudza kachulukidwe ka ethyl acetate. Pamene kutentha kumakwera, kuyenda kwa molekyulu yamadzimadzi kumakula kwambiri ndipo kuchuluka kwake kumawonjezeka, zomwe zimapangitsa kuchepa kwa kachulukidwe. Nthawi zambiri pakupanga mafakitale, kuchuluka kwa ethyl acetate kumakonzedwa molingana ndi kusintha kwa kutentha kuti zitsimikizire kulondola kwa kuyeza.

Kuyera: Kuchuluka kwa ethyl acetate kumakhudzidwanso ndi chiyero chake. Ngati ethyl acetate ikusakanikirana ndi zonyansa zina, monga madzi kapena zosungunulira zina, kachulukidwe kake kangasinthe. Choncho, kugwiritsa ntchito chiyero chachikulu cha ethyl acetate sikungotsimikizira kukhazikika kwa ndondomeko, komanso kumabweretsa deta yodalirika ya kachulukidwe.

Kupanikizika: Ngakhale kuti kupanikizika kumakhala kochepa kwambiri pa kachulukidwe ka madzi, pansi pa zovuta kwambiri kachulukidwe kameneka kamawonjezeka pang'ono. Izi ziyenera kuganiziridwa pakugwiritsa ntchito kwambiri mafakitale, makamaka pamene ntchito zolondola kwambiri zimakhudzidwa.

Kugwiritsa ntchito kachulukidwe ka ethyl acetate
M'makampani opanga mankhwala, kuchuluka kwa ethyl acetate kumakhala kofunikira m'malo angapo. Popanga zinthu monga zokutira ndi zomatira, kachulukidwe deta ndiye maziko a kudziwa kuchuluka kwa zigawo zikuluzikulu. Muzosungirako ndi zoyendetsa, chidziwitso cha kachulukidwe chimathandizira kuwerengera kuchuluka kwa zosungirako ndi ndalama zoyendetsera zinthu. M'njira zolekanitsa monga distillation, kachulukidwe ndi gawo lofunikira pakuzindikiritsa mphamvu ya kulekanitsa kwa zosakaniza za zinthu zofanana.
Mapeto.
Kumvetsetsa kachulukidwe ka ethyl acetate ndi zinthu zomwe zimakhudzidwa ndikofunikira pazinthu zonse zopanga mankhwala. Pozindikira zotsatira za kutentha, chiyero ndi kukakamizidwa kwa kachulukidwe ka ethyl acetate, akatswiri amankhwala amatha kuwongolera bwino momwe amapangira ndikuwongolera mtundu wazinthu. Tikukhulupirira kuti nkhaniyi ikuthandizani kuti mumvetsetse bwino ndikugwiritsa ntchito kachulukidwe ka ethyl acetate pakugwiritsa ntchito.
