Isingeniso

Isoamyl acetate. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwe-isoamyl acetate:

 

Ikhwalithi:

1. Ukubukeka: uketshezi olungenambala.

2. Inzwa yokuhogela: Kunephunga elimnandi elinjengesithelo.

3. Ukuminyana: cishe ngu-0.87 g/cm3.

5. Ukunyibilika: kuncibilika ezinhlobonhlobo zezincibilikisi eziphilayo, njengotshwala nama-ether.

 

Sebenzisa:

1. Ngokuyinhloko isetshenziswa njenge-solvent embonini, engasetshenziswa ukuncibilikisa ama-resin, ama-coatings, ama-dyes nezinye izinto.

2. Ingasetshenziswa futhi njengesithako sephunga elimnandi, elivame ukutholakala ekunambithekeni kwesithelo.

3. Ku-organic synthesis, ingasetshenziswa njengenye yama-reagents wokusabela kwe-esterification.

 

Indlela:

Izindlela zokulungiselela ze-isoamyl acetate ikakhulukazi zimi kanje:

1. Ukusabela kwe-Esterification: I-isoamyl alcohol isabela ne-acetic ngaphansi kwezimo ezine-acidic ukuze kukhiqizwe i-isoamyl acetate namanzi.

2. Ukusabela kwe-Etherification: I-isoamyl alcohol isabela ne-acetic ngaphansi kwezimo ze-alkali ukuze kukhiqizwe i-isoamyl acetate namanzi.

 

Ulwazi Lokuphepha:

1. I-isoamyl acetate iwuketshezi oluvuthayo futhi kufanele igcinwe kude namalangabi avulekile kanye namazinga okushisa aphezulu.

2. Gqoka amagilavu ​​okuzivikela afanelekile kanye nezibuko lapho usebenzisa ukugwema ukuthintana nesikhumba namehlo.

3. Gwema ukuhogela umhwamuko wento futhi uqinisekise ukuthi indawo yokusebenza inomoya okahle.

4. Uma udla, uhogela umoya noma uthintana nenani elikhulu lale nto, funa usizo lwezempilo ngokushesha.

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