Ubucucike bwa DMF bwasobanuwe: Byimbitse Reba Ubucucike bwa Dimethylformamide
1. DMF ni iki?
DMF, izwi mu gishinwa nka Dimethylformamide (Dimethylformamide), ni ibara ritagira ibara, rifite umucyo kandi rikabije rya hygroscopique rikoreshwa cyane mu nganda z’imiti, imiti, imiti n’ikoranabuhanga. Ifite imbaraga nziza kandi irashobora gushonga ibintu bitandukanye kama nimborera, bityo bigira uruhare runini mubikorwa byinshi byinganda.
2. Igitekerezo cyibanze cyubucucike bwa DMF
Ubucucike ni igipimo cya misa nubunini bwibintu, mubisanzwe bigaragazwa nkubunini kuri buri gice. Mu nganda z’imiti, ni ngombwa kumva ubwinshi bwa DMF kuko igira ingaruka ku buryo butaziguye gupima, gutwara no gukoresha ibintu. Ubucucike bwa DMF bukunze kugaragara muri g / cm³ cyangwa kg / m³. Ku bushyuhe busanzwe (20 ° C), DMF ifite ubucucike bwa 0,944 g / cm³. Agaciro gashobora gutandukana gato bitewe nubushyuhe nubuziranenge.
3. Ingaruka yubushyuhe kuri DMF
Ubushyuhe bufite ingaruka zikomeye kubucucike bwa DMF. Mugihe ubushyuhe bwiyongera, ubwinshi bwa DMF buragabanuka. Ibi biterwa na moteri yihuta ya molekuline yamazi, bigatuma intera yiyongera hagati ya molekile bityo misa ikaba mike kubunini bwikibice. Kubikorwa byukuri byinganda, birakenewe gusobanukirwa nimpinduka yubucucike bwa DMF mubushyuhe butandukanye. Kurugero, mugihe ukora imiti yubushyuhe bwo hejuru, impinduka zubucucike bwa DMF zigomba kwitabwaho kugirango metero zukuri neza.
4. Ingaruka yubucucike bwa DMF mubikorwa byinganda
Ubucucike bwa DMF bufite akamaro gakomeye mubikorwa byinganda. Kurugero, DMF ikoreshwa kenshi nkigisubizo mugutegura ibiyobyabwenge. Ubucucike bwabwo bugira ingaruka ku bwinshi no guhunika kwa solvent, ari nako bigira ingaruka ku bwiza no kwera kw'ibicuruzwa byanyuma. Mu musaruro w’imiti, ubwinshi bwa DMF nabwo bujyanye no gutwara ibintu no kubika. Gusobanukirwa n'ubucucike bwa DMF birashobora gufasha kunoza inzira no kugabanya ibiciro byumusaruro.
5. Nigute ushobora gupima ubucucike bwa DMF neza?
Kugirango ubone ubucucike nyabwo bwa DMF, birakenewe gupimwa ukoresheje densitometero ihanitse cyangwa icupa ryihariye rya rukuruzi. Muri laboratoire, ubushyuhe buhoraho hamwe nicyitegererezo cyiza bigomba kubungabungwa kugirango hamenyekane ibisubizo byibipimo. Mu nganda zikora inganda, kugenzura-igihe na byo birashobora gukorwa hamwe na densitometero kumurongo kugirango ibipimo ngenderwaho bishobora guhinduka mugihe gikwiye.
6 Incamake
Ubucucike bwa DMF ni kimwe mu bintu by'ingenzi bigize umubiri wa dimethylformamide, ibintu by'ingenzi bya shimi, kandi gusobanukirwa no kumenya ibiranga ubucucike ni ngombwa mu gukora imiti no kuyishyira mu bikorwa. Binyuze mu gupima neza no gusesengura siyanse, dushobora gukoresha neza DMF kugirango tunoze umusaruro kandi tumenye neza ibicuruzwa. Mu bihe bitandukanye byinganda, impinduka mubucucike bwa DMF zishobora kuzana ingaruka zitandukanye, kubwibyo rero ni ngombwa cyane cyane kubyumva byimbitse no kubigenzura.
Binyuze mu isesengura ryavuzwe haruguru, turashobora kubona ko kumenya amategeko yo guhindura nuburyo bwo gupima ubucucike bwa DMF aribwo shingiro ryogutezimbere iterambere ryimikorere yimiti. Twizere ko iyi ngingo ishobora kugufasha kumva neza akamaro k'ubucucike bwa DMF no gutanga ibisobanuro ku musaruro wawe n'ubushakashatsi.
