N-methylformadi / Cas 123-39-7 / NMF

Tsananguro pfupi:

N-methylformadie (NMF) haina ruvara kuti isimbe mvura ine mhepo ine mwenje ambi-sekunhuhwirira. Iyo polar solvent iyo inowanzoshandiswa mune dzakasiyana siyana dzemakemikari. Iyo compound ine yakadzika viscosity uye iri hygroscopic, zvichireva kuti inobata unyoro kubva kumhepo.

N-methylfamide (NMF) inochenesa kwazvo mumvura, pamwe chete nehuremu hwakasiyana-siyana hwamanikidzwa senge balhopls, anah uye hydrocarbons. Zvivakwa zvayo zvePolar zvinobvumidza kuti zviite kuti ubate zvakanaka neese polar zvinhu uye zvisiri zvepolar zvinhu, zvichiita kuti ive solile simba mumhando dzakasiyana dzemakemikari.

6. Tsvagurudzo: Mubaratori, NMF inoshandiswa kune akasiyana-siyana ekutsvaga zvinyorwa, kusanganisira izvo zvinosanganisira organic synthesis uye mavara sainzi.

Chengetedza

Kuchengetedza chisimbiso kudzivirira kubhururuka, dzivisa mvura, kuratidzwa, kukanganisa kukuru uye kupokana.

Ramba kure nemoto uye kupisa masosi.

1. Mudziyo: Shandisa midziyo yemoto yakagadzirwa nezvinhu zvinowirirana, senge girazi kana dzimwe mapurasitiki, kudzivirira kusvibiswa uye kusvibiswa.

2. Tembiricha: Chengetedza NMF munzvimbo inotonhorera, yakaoma kure kubva kune yakananga zuva uye kupisa. Zvakanakisa, inofanira kuchengetwa pamhepo tembiricha, asi dzivisa kuratidzwa nekunyanyisa kupisa.

3. Ventilation: Ita shuwa nzvimbo dzekuchengetedza dzakanyatsovhuvhuta kuti uderedze vapor

5. Label: zvakajeka manyorerwo emidziyo ine zita remakemikari, njodzi ruzivo, uye risiti rekutambira kuti rive nechokwadi chekubata uye kuzivikanwa.

6. Zvivakwa Zvekudzivirira

7. Kurasa: kurasa nmf uye chero zvinhu zvakasvibiswa mukuteerera nemirairo yemuno.

2. Kuvapo mukuputa utsi.

Nyevero Kana Tumira N-MethylforMadide?

1. Regulatory kutevedzera: Ita shuwa kuti iwe uteedzere nemitemo yemuno, yenyika, uye zvepasi rose maererano neyekufambisa kwezvinhu zvine njodzi. NMF inogadziriswa seyakareba zvinhu uye saka inogona kuve iri pasi pemirairo yekutumira (semuenzaniso, UN nhamba, zita rekutumira rakakodzera).

2. Kutakura: Shandisa zvakakodzera kurongedza zvinhu zvinowirirana neNMF. Kazhinji, izvi zvinosanganisira kurwisa kwemicess, zvinongedzo-zvinoputika midziyo. Ita shuwa midziyo yakachengetedzwa zvakachengetedzwa kuti udzivise kufambisa panguva yekufambisa.

3. Label: zvakajeka Label packing neiyo chaiyo njodzi zviratidzo uye ruzivo, kusanganisira zita rechokwadi rekutumira, UN nhamba uye chero nyevero dzine njodzi dzakakodzera. Izvi zvinobatsira kuona kuti vanobata vanonzwisisa zviri mukati mezvitakura uye nenjodzi dzakabatana.

Is N-methylformamide inokuvadza munhu here?

1. Inhalation: Kuratidzwa kuNMF vapombi kunogona kutsamwisa turakiti rekufema, zvichikonzera zviratidzo zvakadai sekukosora, kupfupika kwemweya, uye kurapa kutsamwiswa. Kufumurwa kwenguva refu kana kwepamusoro-soro kunogona kukonzera matambudziko akakomba ekufema.

2.. Zvinokurudzirwa kupfeka magurovhosi ekudzivirira kana uchibata zvinhu izvi.

5. Kureba-miganho: Yakareba-kuratidzwa kuNMF kunogona kuburitsa uye kusimudzira hutachiona. Dzimwe zvidzidzo zvakaratidza kuti zvinogona kuve nemhedzisiro yakaipa pakubereka uye feta yekusimudzira.

6 Ita shuwa kuti nzvimbo yebasa yakanyatsonaka.

7. Kuongorora kwemazambiringa: kana uchionana, tsvaga kurapwa nekukasira uye kutora matanho ekutanga ekutanga, sekunyepedzera nzvimbo yakakanganisika nemvura uye kubvisa zvipfeko zvakasvibiswa.
