Isingeniso
I-3,4-Dimethoxypropiophenone (eyaziwa nangokuthi i-DMBA) iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso semvelo yayo, ukusetshenziswa, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: 3,4-dimethoxypropiophenone uketshezi olungenambala noma ikristalu emhlophe.
- Ukunyibilika: Ine-solubility ephezulu kuma-ethers, utshwala nezincibilikisi zemvelo.
- Ukuzinza: Izinzile kodwa ijwayele ukubola lapho kukhanya ilanga.
Sebenzisa:
- Ama-Chemical reagents: I-3,4-dimethoxypropiophenone ingasetshenziswa njenge-reagent ku-organic synthesis kanye nocwaningo lwamakhemikhali.
Indlela:
Indlela yokulungiselela ye-3,4-dimethoxyphenylacetone ngokuvamile isebenzisa i-styrene njengempahla eluhlaza, ibhekana ne-oxidation reaction ukuze yakhe i-hydroquinone, bese yethula amaqembu e-methoxy ezindaweni 3 kanye ne-4 ngokusebenzisa ukusabela kwe-acylation kanye nokusabela kwe-methanol.
Ulwazi Lokuphepha:
- Ubuthi: Abukho ubuthi obuncane kubantu, kodwa kusadingeka ukuthi uthathe izinyathelo zokuphepha futhi ugweme ukuhogela, isikhumba noma ukuthintana kwamehlo.
- Ukuvutha: I-3,4-dimethoxypropiophenone iyavutha futhi ingasha lapho ibhekene namalangabi avulekile noma amazinga okushisa aphezulu.
- Umthelela wendawo: Imfucuza nezisombululo kufanele kulahlwe ngendlela efanele ukuze kuvinjwe ukungcoliswa kwemvelo.
- Isitoreji: Kufanele sigcinwe endaweni epholile, eyomile, nengena umoya, kude nomlilo nezinto ezivuthayo.
