Zvinhu zvinokanganisa nzvimbo yekubikira yeTetrahydrofuran uye zvinoshanda zvinoshanda
Tetrahydrofuran (thf) ishandare yakashandiswa zvakanyanya muindasitiri yemakemikari ane solvency solvency uye yakadzika kushandiswa muminda yemigodhi yemishonga, makemikari uye midziyo yemidziyo. Mune ino bepa, isu tichakurukura zvakadzama hunhu hwekutanga hweTetrahydroupuran, zvinhu zvinokanganisa uye zvakakoshesesa mune zvinoshanda zvinoshandiswa.
I. Basic Staket of Tetrahydrofuran uye Yayo Boling Point
Tetrahydrofuran (thf) ndeye cyclic ether neemakemikari formula c4h8o. Sezvinowanzo shandiswa solvent, Tetrahydrofuran isiriyo isina ruvara uye inojekesa mvura pamhepo tembiricha uye ine yakakwirira kwazvo. Tetrahydrofuran ine nzvimbo yekubika yeanenge 66 ° C (anenge 339 k), iyo inoita kuti zvive nyore kuputika uye kupora mumakemikari akawanda maitiro. Tetrahydrofur's yakaderera inovhara pfungwa zvinoreva zvakare kuti inogona kubviswa kubva kune reaction system yakanyatsokurumidza, kuderedza kupindira nekuita kwekutevera maitiro.
Zvinhu zvinokanganisa nzvimbo yekubikira yeTetrahydrouran
Kunyangwe iyo yekubikira yeTetrahydrouran ine kukosha kwakarongeka mumabhuku emakemikari, mukuita iyo yekubikira yenzvimbo yeTetrahydrouran inogona kukanganiswa nezvikamu zvakati:
Simba rekumanikidza kumanikidzwa kweAmbired: Iyo yekubikira yeTetrahydrofuran inosiyana nekumanikidzwa kweAmberion. Panguva yekudyidzana kwemhepo, iyo yekubikira yeTetrahydrouran ndeye 66 ° C. Pasi pekudzvinyirirwa kwakanyanya kana kuderera, nzvimbo yekubikira ichachinja nenzira kwayo. Kazhinji, zvakakwirira kumanikidzwa, kukwirira kwepamberi kwekutya kweTetrahydrouran; Kukurukurirana, mune vacuum, iyo nzvimbo yekubikira ichaderera.

Simba rekuchena: Kusvibiswa muTetrahydrofuran kuchave nemhedzisiro pachirevo charo. Kana Tetrahydrofururur Solution ine huwandu hwakareba hwemvura kana zvimwe zvinosvibiswa solives, iyo nzvimbo yayo yekubikira inogona kusiyana neiyo yeiyo yakachena Tetrahydroan. Kunyanya, kuvapo kwemanyoro, uko kunonyanyoka mumvura, kunogona kuumba iyo Azeotrope neTH, zvichikonzera shanduko diki mune yekubikira.

Azeotropic phenomena: mune, Tetrahydrofuran inowanzo kuvhenganiswa pamwe nemamwe mashiromisi ekuumba azotropic musanganiswa. Pfungwa dzinobikwa dzemisipa yakadaro kazhinji dzinowanzove dzakasiyana neiya yezvikamu zvega uye zvinoshamisa zvinomutsa maitiro ekuparadzanisa. Naizvozvo, kana uchisarudza Tetrahydrouran sechirimo, chakakosha kuti unzwisise maitiro ayo ezotropic nemamwe ma compounds.

III. Zvinoshanda zvinoshanda zveTetrahydrofuran Boiling Point muindasitiri
Iyo inovhara Point Properties yeTetrahydrouran ine zvakakosha zvikumbiro mukugadzirwa kwemakemikari:
Kudzoreredza uye kushandirazve kweSolvent Ichi chivakwa chisingangobatsire kuderedza mari yekugadzira, asi zvakare inoderedza maitiro emamiriro ekunze.

Zvikumbiro muPolymerisation: Mune mamwe mapepa ekufunga, Tetrahydrofuran ane mwero anoyevedza nzvimbo, inobvumidza kunyatso kudzora tembiricha uye simbisa kuti kuita kunoenderana zvakanaka. Hosha yayo inogona zvakare kubviswa mukupera kwekuita, kudzivirira mhedzisiro yakaipa pakuchena kwechigadzirwa.

Chishandiso mudhaka synthesis: Tetrahydrofuran inowanzo shandiswa solvent mune zvinodhaka synthesis, iyo nzvimbo yayo yekubika iri pakati nepakati, iyo inokodzera kudzora kwezvinhu zvekuita. Tetrahydrofur

Mhedziso
Iyo yekubikira point yeTetrahydrofuran ndiyo imwe yezvinhu zvayo zvakakosha mune maindasitiri ekushandisa. Kunzwisisa pfungwa yekubika yeTetrahydropuran uye kugadzirwa kwayo kunogona kubatsira makambani emakemikari kuve nani kudzora mamiriro ezvinhu mukugadzirwa chaiko uye kugadzirisa kunaka uye kugadzirwa kwezvigadzirwa. Kushandisa zvine musoro kweiyo yakaderera yekubika kwenzvimbo inogona kubatsira kuzadzisa kudzokororwa zvinobudirira zviwanikwa uye kukurudzira kwakasimba kwenzvimbo. Paunenge uchisarudza uye uchishandisa Tetrahydrofuran sosi solvent, kuzere kwekurara kwezvinhu zvayo zvekutadza uye kufurira zvinhu ndiyo kiyi yekuita kuchengetedza uye kushanda kwemakemikari maitiro.
