Isingeniso

I-2-nn-pentylfran iyinhlanganisela yemvelo. Okulandelayo yisingeniso kwezinye zezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-2-nn-pentylfran:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Ukuncibilika: kuncibilika otshwaleni nakwi-ether, akuncibiliki emanzini

- Izakhiwo zamakhemikhali: Izwela kuma-oxidants nama-asidi aqinile, ajwayele ukusabela kwi-polymerization

 

Sebenzisa:

- I-2-nn-pentylfuran ivamise ukusetshenziswa njengendawo ephakathi ku-organic synthesis kanye nesayensi yezinto

- Ngenxa yezakhiwo zayo ezisobala zokukhanga, isetshenziswa kakhulu ekudayini nasekudayeni ukwelapha amanzi angcolile

 

Indlela:

I-2-nn-pentylfran ingalungiswa ngu:

- I-2-nn-pentylfuran itholwe ngokusabela okuqondile kwe-alkynypropylberyllium kanye nokusabela kwe-n-pentylene, bese kuncishiswa ukusabela ukuthola i-2-nn-pentylfuran.

- I-2-ammonium sulfate 5-hydroxypentanone ikhiqizwa ukusabela kwe-2-pentenone ne-ammonium sulfate, bese i-2-n-penylfuran itholakala ngokushisa nokuphelelwa amandla kwamanzi.

 

Ulwazi Lokuphepha:

- I-2-Nn-pentylfran inezinto zokucasuka kanye nokulimala kwamehlo, ngakho-ke gwema ukuthintana nesikhumba namehlo uma uyisebenzisa.

- Izinyathelo ezinhle zokungenisa umoya kufanele zithathwe ngesikhathi sokusetshenziswa ukugwema ukuhogela amagesi.

- Kufanele igcinwe endaweni epholile, eyomile, nengena umoya, kude nomlilo kanye nama-oxidants.

- Lapho uphatha futhi ugcina, sicela ubhekisele ezinqubweni zokusebenza eziphephile zezimpahla eziyingozi futhi ulahle kahle imfucuza ekhiqiziwe.

  • Okwedlule:
  • Olandelayo:
    • Bhala umyalezo wakho lapha futhi usithumelele wona
