Zinthu zomwe zikukhudza malo otentha a tetrahydroforan ndi ntchito zothandiza
Tetrahydroforan (thf) amagwiritsidwa ntchito kwambiri zosungunulira zamankhwala ndi solvency yayikulu komanso zoopsa zochepera, chifukwa chake zagwiritsidwa ntchito kwambiri m'minda ya mankhwala a mankhwala opanga mankhwala, mankhwala ndi zinthu za sayansi. Mu pepala ili, tikambirana mozama za mawonekedwe a malo otentha a tetrahydroforan, zomwe zikukhudza ndi kufunikira kwake mu mapulogalamu othandiza.
I. Malo oyambira a tetrahydroforan ndi malo ake owira
Tetrahydroforan (thf) ndi ether ya cyclic ndi njira ya mankhwala C4H8O. Monga zosungunulira kawiri, tetrahydroforan ndi madzi opanda utoto komanso owoneka bwino kutentha komanso amakhala ndi kusazikira kwakukulu. Tetrahydroforan ili ndi malo owiritsa pafupifupi 66 ° C (pafupifupi 339 k), zomwe zimapangitsa kuti zikhale zosavuta kutuluka ndikuchira pamachitidwe ambiri. Kuphatikiza kwa tetrahydroforan kumatanthauzanso kuti zitha kuchotsedwa ku dongosolo lazomwe zimachitika mwachangu, kuchepetsa zomwe zimasokoneza.
Zinthu zomwe zikukhudza malo otentha a tetrahydroforan
Ngakhale malo owira a tetrahydroforan ali ndi mtengo wokhazikika mu mabuku owiritsa, pochita zowotcha za tetrahydroforan amatha kukhudzidwa ndi zinthu zingapo:
Kutengera kwa kupanikizika kozungulira: malo otentha a tetrahydroforan amasiyana ndi kupanikizika kozungulira. Pamavuto a m'mlengalenga, malo otentha a tetrahydroforan ndi 66 ° C. Pansi kapena yotsika kwambiri, malo owiritsa adzasintha moyenerera. Nthawi zambiri, kupanikizika kwambiri, malo owira kwambiri a tetrahydrofor; Mofananamo, pamutu, malo owira chidzachepa.

Mphamvu ya kuyera: Zonyansa ku Tetrahydroforan idzathandiza pa malo ake owira. Ngati tetrahydroforan muli madzi okwanira kapena zosungunulira zina, malo ake owira mtengo amatha kusiyana ndi za tetrahydroforan. Makamaka, kupezeka kwa chinyezi, komwe kumasungunuka pang'ono m'madzi, kumatha kupanga azetrope ndi thf, zomwe zimapangitsa kuti zisinthe pang'ono.

Azetropic Phenomena: Pochita, Tetrahydroforan nthawi zambiri imasakanikirana ndi ma sol sol osungunuka kuti apange zosakhazikika za Azetrotropic. Mfundo zosakanikirako nthawi zambiri zimakhala zosiyana ndi zigawo chimodzi ndipo azeotropy amakakamiza kupatukana. Chifukwa chake, posankha tetrahydroforan ngati zosungunulira, ndikofunikira kumvetsetsa mawonekedwe ake a Azetropic ndi zina.

Iii. Ntchito zothandiza za Tetrahydroforan malo owiritsa m'makampani
Malo otentha a tetrahydroforan ali ndi mapulogalamu ofunikira pakupanga mankhwala:
Kubwezeretsa ndi kugwiritsidwa ntchito kwa ma soltrahydrotsiran ali ndi malo ocheperako, ndikosavuta kubwezeretsedwa chifukwa cha kusakaniza komwe kumachitika ndi distillation kapena njira zina zolekanitsa. Katunduyu samangothandiza kuchepetsa ndalama zopanga, komanso amachepetsa zomwe zimakhudza chilengedwe.

Mapulogalamu mu polymerisation: Mu polymerrotion yomwe imachitika pakusintha, tetrahydrofuran ili ndi malo owiritsa pang'ono, omwe amalola kuti ithe kuyendetsa bwino kutentha ndikuwonetsetsa kuti zinthu zitheke. Kulowerera kwake kumathanso kuchotsedwa kumapeto kwa zomwe anachita, kupewa mavuto olakwika pa chiyero chazogulitsa.

Kugwiritsa ntchito mu kaphatikizidwe ka mankhwala: Tetrahydroforan nthawi zambiri amagwiritsidwa ntchito ngati zosungunulira mu mankhwala a mankhwala a mankhwala, malo ake owiritsa ndi okhazikika, omwe amathandizira kuwongolera kwazomwe zimachitika. Katundu wa Tetrahydroun wofulumira amapangitsa kuti zikhale zothandiza kwambiri pakukonzekera ndi kuyeretsa.

Mapeto
Malo owiritsa a tetrahydroforan ndi amodzi mwa malo ake ofunikira mu mafakitale. Kumvetsetsa malo otentha a tetrahydroforan ndipo zinthu zomwe zimapangitsa kuti zithandizire makampani kuti mugwiritse ntchito bwino zomwe zikuchitika ndikusintha bwino zinthu ndi zopanga. Kugwiritsa ntchito moyenera madera ake owotcha kungathandize kukwaniritsa zinthu zabwino ndi kukhazikitsa chilengedwe. Mukamasankha ndi kugwiritsa ntchito tetrahydroforan monga zosungunulira, kulingalire kwathunthu mawonekedwe awo ndi zinthu zomwe zimapangitsa kuti zitsimikizike ndi njira yowonetsetsa chitetezo cha mankhwala.
