DMF Boiling Point: kutaridzika kwakazara pane zvivakwa zve dimethylfamadi
DimethylfMide (DMF) organc solvent yakashandiswa zvakanyanya mumakemikari, mishonga uye maindasitiri yemagetsi. Munyaya ino, isu tichakurukura zvakadzama nzvimbo yekubika yeDMF, chivakwa chakakosha chemuviri, uye ongorora zvakaringana pazvinhu zvinoshanda.

1. Zvekutanga zvivakwa zveDMF
DMF imvura isina ruvara yakajeka ine isina kusimba ammonia inonhuwira. Iyo polar solvent uye inokanganisa nemvura uye yakawanda organic sol sol. Nekuda kwekushamisira kwayo solubility uye yakakwira boling point, DMF inowanzo shandiswa mumakemikari synthesis, polymerisation maitiro, fiber uye kugadzira fiber uye kugadzirwa kwefirimu. Kuziva iyo yekubika yeDMF ndeimwe yemakiyi ekushandiswa kwakakodzera kweichi solvent.

2. Ndeipi nzvimbo yekubikira yeDMF?
DMF ine point yekubika ye307 ° F (153 ° C). Iyi yakakwira nzvimbo yekubika inobvumira DMF kuti ishandiswe pakukwirira kusimudzirwa pasina kugadzikana Mune izvi zvekushandisa, DMF inopa nzvimbo yakachengeteka uye inoshanda yekuita.

3. Chikonzero cheDMF Boiling Point pane yayo application
Iyo yekubika point yeDMF yakananga inobata mashandisiro ayo ayo maindasitiri akasiyana. Muindasitiri yemishonga, nzvimbo yakakwirira yekubika inoreva kuti DMF inogona kunyungudutsira yakaoma-ku-kugadzirisa zvinodhaka pakupisa kwakakwirira, kuvandudza kushanda kwezvinodhaka synthesis. Mune indasitiri yemakemikari, yakakwira yekubika madhiri inoshandiswa mukuita zvinoda kupisa kwakanyanya, sekugadzirwa kwemazwi nemapuranga. Ichi chivakwa chinoitawo kuti DMF isiriyo soli yekunyora yekudziya tembiricha uye inks.
Kune rimwe divi, iyo nzvimbo yekubikira yeDMF zvakare inokanganisa kupora kwayo uye kushamwaridzana kwakawanda. Iko kudzikisira kunodiwa kuti udzore dmf, iyo yekubikira ipfungwa inosarudza iyo simba rekushandisa uye kushanda kweiyo yekugadzirisa maitiro. Naizvozvo, mune maindasitiri ekushandisa, kwete chete zvimiro zveDMF chinoda kufungwa nezvazvo,

4. Tembiricha mhedzisiro paDMF Boiling Points
Kunyangwe iyo DMF Boint point ndeye 153 ° C pane yakajairwa kumanikidzwa kwemweya, shanduko mukumanikidzwa kweAmberion kunogona kuitawo pfungwa yekubika. Pazvinetso zvakadzika, iyo yekubikira yeDMF inoderera, iyo iri mukana weChium Dhiclilation proctions iyo Solvent kupora kunogona kuwanikwa kupisa kwezvinhu zvakaderera nekukuvara kwakanyanya kune zvinhu zvinotyisa. Kunzwisisa uye ruzivo rwekuchinja muDMF Boiling point pane dzakasiyana dzvinyiriro chikamu chakakosha chekugadzirisa maitiro eindasitiri.
5. Kuchengetedza uye kutevedzera zvakatipoteredza

DMF inzvimbo isina kujairika, uye kunyangwe yayo yakakwira nzvimbo yekuchengetera, kuriridzwa kunofanirwa kutorwa kuti iite kuti njodzi dzekusamwisa panguva yekushisa kwakanyanya. Kufumurwa kwenguva refu kune iyo Mpf inogona kunge iine maitiro ehutano hwevanhu, saizi dzakakora dzinofanira kutorwa panguva yekuita, uye kuraswa kweDMF kutambisa mvura, dzivirira kusvibiswa kwezvakatipoteredza.

Pfupiso
Kunzwisisa iyo DMF Boint Pfungwa uye kuti inobata sei mashandiro eindasitiri ruzivo kune avo vanoshanda mumakemikisheni ezvemakemikari, uye yakakwira yekubika nzvimbo yeDMF pa153 ° C inopa mukana wakakura mukushandiswa kwakanyanya. Kunzwisisa kwakakodzera kwekukanganisa kweDMF Boiling Pfungwa pane matanho uye matanho ekuchengetedza anogona kubatsira kuti agadzirise maitiro, achivandudza kushanda zvakanaka uye kuve nechokwadi chekuchengetedza. Izvo zvakakosha kutevedzera zvakachengeteka uye zvakatipoteredza zvichironga kana uchishandisa DMF kuve nechokwadi chekuti mabhenefiti ayo akawedzerwa.
