3-phenylprop-2-ynenitrile (CAS# 935-02-4)

Isingeniso

I-3-phenylprop-2-ynenitril iyinhlanganisela ye-organic enefomula yamakhemikhali i-C9H7N. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukulungiswa kanye nolwazi lokuphepha:

Imvelo:

1. Ukubukeka: I-3-phenylprop-2-ynenitrile iwuketshezi olungenambala ukuya kokuphuzi okukhanyayo.

2. Iphuzu elincibilikayo: cishe -5°C.

3. Iphuzu lokubilisa: cishe ku-220°C.

4. ukuminyana: cishe ngu-1.01 g/cm.

5. Ukunyibilika: I-3-phenylprop-2-ynenitrile iyancibilika kuzincibilikisi eziningi eziphilayo, njenge-ethers, utshwala namaketone.

Sebenzisa:

1. njengengxenye emaphakathi ekuhlanganiseni okuphilayo: I-3-phenylprop-2-ynenitrile ingasetshenziswa ukuze kuhlanganiswe ezinye izinhlanganisela eziphilayo, njengezinhlanganisela ezinuka kamnandi, izinhlanganisela ze-nitrile, njll.

2. Isayensi yezinto ezibonakalayo: Ingasetshenziselwa ukuhlanganiswa kwe-polymer nokuguqulwa kokusebenza ukuze kushintshwe izakhiwo zama-polymers.

Indlela:

I-3-phenylprop-2-ynenitril ilungiswa ngokusabela inhlanganisela ye-phenyl nitro ne-sodium cyanide. Izinyathelo ezithile zifaka:

1. Inhlanganisela ye-phenyl nitro isabela nge-sodium cyanide ngaphansi kwezimo ze-alkaline.

2. I-3-phenylprop-2-ynenitril ekhiqizwa ngesikhathi sokusabela itholakala ngokukhipha kanye nokuhlanzwa kwe-distillation.

Ulwazi Lokuphepha:

1. I-3-phenylprop-2-ynenitril kufanele isetshenziswe endaweni enomoya omuhle, ukugwema ukuhogela isitimu noma ukuthintana nesikhumba namehlo.

2. Kungase kucasule isikhumba namehlo, ngakho hlambulula ngamanzi ngokushesha ngemva kokuxhumana.

3. Gqoka izinto zokuzivikela ezifanele njengezibuko, amagilavu ​​namajazi elebhu lapho usebenza.

4. I-3-phenylprop-2-ynenitril kufanele igcinwe esitsheni esivaliwe, kude namalangabi avulekile kanye namazinga okushisa aphezulu.

5. Lapho kulahlwa imfucuza, kufanele kulandelwe imithetho yokulahlwa kwendawo.
